AIA (American Institute of Architects)

The American Institute of Architects (AIA) and its Committee on the Environment (COTE) have selected the top ten examples of sustainable architecture and ecological design projects that protect and enhance the environment. The projects will be honored at the AIA 2014 National Convention and Design Exposition in Chicago. The COTE Top Ten Awards program, now in its 18th year, is the profession's best known recognition program for sustainable design excellence. The program celebrates projects that are the result of a thoroughly integrated approach to architecture, natural systems and technology. They make a positive contribution to their communities, improve comfort for building occupants and reduce environmental impacts through strategies such as reuse of existing structures, connection to transit systems, low-impact and regenerative site development, energy and water conservation, use of sustainable or renewable construction materials, and design that improves indoor air quality.

2014 Top Ten Award Winners with Green Roofs:

  • Bushwick Inlet Park; Brooklyn, New York; Kiss + Cathcart, Architects
    This project is the first phase of the transformation of the Greenpoint–Williamsburg waterfront from a decaying industrial strip to a multifaceted public park. The design team integrated a program of playfields, public meeting rooms, classrooms, and park maintenance facilities, into a city-block sized site. The park building becomes a green hill on the west side, making 100% of the site usable to the public, and offering views to Manhattan. Below the green roof is a complex of building systems – ground source heat pump wells, rainwater harvest and storage, and drip irrigation. A solar trellis produces half the total energy used in the building.

  • Gateway Center - SUNY-ESF College of Environmental Science & Forestry, Syracuse, NY; Architerra
    The SUNY-ESF College of Environmental Science & Forestry Gateway Center is a striking symbol of environmental stewardship and climate action leadership. This LEED Platinum campus center meets ESF’s goal of reducing the overall carbon footprint of the campus through net positive renewable energy production, while creating a combined heat and power plant and intensive green roof that serve as hands-on teaching and research tools. The double-ended bioclimatic form exemplifies passive solar design. Net positive energy systems integrated with the design serve four adjacent ESF buildings, providing 60% of annual campus heating needs and 20% of annual power needs. [4.23.14]

2013 Top Ten Award Winners with Green Roofs:

  • Swenson Civil Engineering Building; Duluth, Minnesota - Design Architect: Ross Barney Architects, Architect of Record: SJA Architects
    As an educational facility whose curriculum directly impacts the natural environment, the building overtly exposes sustainable systems and materials. 73% of the site is devoted to pervious materials and landscaping, reducing site detention requirements. An extensive green roof with native plants covers 22% of the roof, reducing storm water rates and filtering impurities. Storm water is directed from the roof to three scuppers and into above ground cylinders filled with rocks for filtering. Storm water eventually makes its way to a French drain system of underground water storage pipes for retention. The site lighting is minimal, and all fixtures are equipped with full cut-off optics.

  • Yin Yang House; Venice, California - Brooks + Scarpa
    This sound passive design strategy combined with a very tight perimeter building envelope and other active sustainable features such as the 12kw solar system make this home a zero energy consumption home. It produces 100% of its energy needs and since completion, has never received an electric bill. The design maximizes the opportunities of the mild, marine climate with a passive cooling strategy using cross-ventilation and a thermal chimney. A large cantilevered roof overhang shades all the bedrooms from direct sunlight while providing ample natural light and ventilation. The project also has green roofs, its own storm water retention system and retains 95% of roof storm water on site. [4.22.13]

The American Institute of Architects (AIA) introduced the first overview guide on how architects can implement  the International Green Construction Code (IgCC) in their practice, which was introduced in March by the International Code Council (ICC). The guide, entitled simply “Guide to the IgCC,” is meant as a one-stop-shop document exclusively for AIA-member architects working in jurisdictions where the IgCC is adopted or soon will be. The announcement was made on the opening day of the AIA’s 2012 National Convention. [5.17.12]

The American Institute of Architects (AIA) and its Committee on the Environment (COTE) have selected the top ten examples of sustainable architecture and green design solutions that protect and enhance the environment.

2012 Top Ten Award Winners with Green Roofs:

  • Mercy Corps Global Headquarters; Portland, OR - THA Architecture
    The roof reduces heat-island effect using light-colored roofing combined with a 3,800 sf green roof, which not only filters water and slows stormwater discharge but also contributes to better air quality in this area of the downtown.

  • Kensington High School for the Creative and Performing Arts; Philadelphia, PA - SMP Architects (in collaboration w/ SRK Architects)
    The project received expedited review and approval by the Water Department (critical for its tight construction schedule) by reducing stormwater run-off to zero. This was accomplished through the use of porous paving materials, grass paving blocks and no-mow turf. Visible (even from the EL) strategies included vegetated roofs on 45% of the roof area and a rain garden filled with flowering plants at the main entrance.

  • University of Minnesota Duluth – Bagley Classroom Building; Duluth, MN - Salmela Architect
    The design is very sensitive to issues of site disturbance, water run-off, and views and meets the energy efficiency goals of the University while gracefully marking the entry to the nature preserve and allowing the students to study the natural systems without disturbing them. The building footprint and heat island effect were addressed by minimizing size to 1995 gsf and 1550 nsf and providing a vegetative roof. [4.19.12]

The American Institute of Architects (AIA) has selected the 2012 recipients of the Institute Honor Awards, the profession’s highest recognition of works that exemplify excellence in architecture, interior architecture and urban design.

American Rivers

Without proper maintenance, any type of infrastructure can lose functionality and ultimately fail. As more communities move towards adopting green infrastructure as a cost-effective approach to manage polluted runoff, it is critical that local governments address barriers to operations and maintenance. Despite the benefits of green infrastructure, operations and maintenance has been repeatedly raised as a technical barrier to adoption of green infrastructure and remains a concern for many local governments in the Chesapeake Bay region and across the country. American Rivers and Green for All collaborated to develop two companion reports exploring different elements of operations and maintenance of green infrastructure in the region.

American Rivers Releases Guide To Integrate Green Infrastructure Into Stormwater Permits. This guide is intended to be a resource for community and watershed advocates that provides clear examples of new developments in municipal stormwater permits that foster on-site management of stormwater by encouraging or requiring that runoff be controlled through the practices commonly referred to as “low impact development” or “green infrastructure.” These permits represent an emerging new generation of regulatory approaches and reflect the emerging expertise of water advocacy organizations, stormwater professionals and permitting agencies. Our goal is to provide up-to-date information about new trends in stormwater permitting and examples of permits that demonstrate leadership toward standards that will build green infrastructure and compliance with water quality standards. With this tool, we hope to inform and inspire continued progress toward stormwater permitting and management that protects our rivers and other shared waters, invigorates healthy communities, and provides cost-effective solutions for stormwater managers. You may download Permitting Green Infrastructure: A Guide to Improving Municipal Stormwater Permits and Protecting Water Quality. [1.17.13]

In our latest white paper, we explore how green infrastructure practices can mitigate the urban heat island effect and provide a number of other public health benefits. Growing Green: How Green Infrastructure Can Improve Livability and Public Health provides a compendium of potential benefits that green infrastructure provides to improve community health and livability. From rain gardens to green roofs, green infrastructure practices decrease pollutant loadings into waters, which can reduce illness from recreational contact or polluted drinking water. Green infrastructure solutions can also improve air quality and mitigate the urban heat island effect to lower heat stress related fatalities. [7.23.12]

In their recent report, Banking on Green, American Rivers explained the many benefits of using green roofs and other techniques like rain gardens and green streets to save money, reduce energy use and flooding, and keep people healthy and water clean. Now, working with Goodby Silverstein & Partners they’ve just released Get More Green – an interactive tool that let’s you virtually “green” a roof in your own community to find out how much money you’ll save in heating and cooling costs as well as how much dirty water you’ll keep out of your local river! [4.20.12]

Communities looking for the most cost-effective options for managing polluted runoff and protecting clean water should choose green infrastructure solutions, according to a report released today by American Rivers, the Water Environment Federation (WEF), the American Society of Landscape Architects (ASLA), and ECONorthwest. The report, Banking on Green: How Green Infrastructure Saves Municipalities Money and Provides Economic Benefits Community-wide, demonstrates that green infrastructure practices can offer more cost-effective solutions relative to traditional infrastructure approaches. The report also details additional potential benefits of green infrastructure such as lower energy expenses, reduced flood damage and improved public health. [4.12.12]

Innovative financing and pricing flexibility are key to preparing the nation’s aging freshwater systems to handle growing demand and environmental challenges, according to a Charting New Waters report released by The Johnson Foundation at Wingspread, American Rivers and Ceres. The Financing Sustainable Water Infrastructure report, is the product of a meeting convened by The Johnson Foundation, in collaboration with American Rivers and Ceres, which brought together a group of experts to discuss ways to drive funding toward the infrastructure needed for the 21st century.

Want to create 1.9 million American jobs and add $265 billion to the economy? Upgrade our water infrastructure. That's the message of Water Works: Rebuilding Infrastructure, Creating Jobs, Greening the Environment, a report by Green For All, in partnership with American Rivers, Pacific Institute, and the Economic Policy Institute. The report looks at an investment of $188.4 billion in water infrastructure—the amount the EPA indicates would be required to manage stormwater and preserve water quality. That investment would inject a quarter of a trillion dollars into the economy, create nearly 1.3 million direct and indirect jobs and result in 568,000 additional jobs from increased spending. [10.4.11]

Quantifying the economic value of green infrastructure’s benefits is the key to helping municipalities adopt this innovative and cost-effective stormwater management approach, according to a new report by the Center for Neighborhood Technology (CNT) and American Rivers. “The Value of Green Infrastructure: A Guide to Recognizing Its Economic, Social and Environmental Benefits” is a broad analysis that is the first to place an economic value on the numerous benefits provided by green infrastructure. [1.21.11]

American Rivers and the Green Reserve - Funding Green Infrastructure Solutions: A new report issued by American Rivers analyzes how the $1.2 billion of green water infrastructure funding under the American Recovery and Reinvestment Act has been spent. According to "Putting Green to Work: Economic Recovery Investments for Clean and Reliable Water," demand for green infrastructure projects has never been higher. The report highlights case studies and makes recommendations for how to best leverage future spending for clean and reliable water. Of the 19 states studied for the report, Maryland stands out as exemplary, with the highest percentage (64 percent) of green projects. Other strong states include New York and Rhode Island, where over 40 percent of green reserve-funded projects added elements such as wetlands, green roofs and water efficiency to existing, centralized water infrastructure.

American Society of Landscape Architects)

The American Society of Landscape Architects (ASLA) has launched a new guide to explain the many benefits of “green infrastructure” — designed systems that harness nature to create proven benefits for communities and the environment. Green infrastructure includes park systems, urban forests, wildlife habitat and corridors, and green roofs and green walls. These infrastructure systems protect communities against flooding or excessive heat, or help to improve air and water quality, which underpin human and environmental health. [9.3.14]

The outlook remains positive for landscape architecture firms, according to the American Society of Landscape Architectssecond quarter 2014 Business Quarterly survey. The survey revealed a marked rise in billable hours and inquiries for new work. Hiring plans rose slightly from the last quarter. The survey indicates widespread strengthening of the landscape architecture industry, says Nancy Somerville, Hon. ASLA, executive vice president and CEO of ASLA. We are very much encouraged by the growth shown during the second quarter and rise in hiring plans, particularly among mid-sized firms. Hopefully, these signs point to continued growth for the rest of this year. The American Society of Landscape Architects (ASLA) Business Quarterly survey asks quarterly benchmarks on key statistics including billable hours, inquiries, and hiring plans. The survey is not intended to be statistically significant but instead provides a snapshot of the landscape architecture industry. [8.12.14]

ASLA launches new educational resources for K-12 Teachers and Educators. The American Society of Landscape Architects is launching two new educational resources that will help young people and teachers explore the landscape architecture profession-a newly redesigned Career Discovery website and the new Tools for Teachers.

The intent of the legislation is to provide critical support to advanced stormwater strategies that improve our nation's ability to effectively manage polluted runoff and sewage overflows while relieving pressure on aging infrastructure. [11.15.13]

In honor of National Landscape Architecture Month in April, landscape architects across the country will host a variety of activities to celebrate the profession and show how the profession promotes public health. This year’s theme will be 'Healthy Living Through Design'. Since Olmsted’s time the field of landscape architecture has taken a lead in solving environmental problems and promoting civic planning for healthy living. Recent innovations include green roofs, sustainability certification, green infrastructure, and active transportation measures including complete streets." [3.19.13]

The American love affair with the back yard shows no signs of slowing, according to the 2012 Residential Landscape Architecture Trends survey conducted by the American Society of Landscape Architects. The results show a preference for an undemanding outdoor space for lots of entertaining. Landscape architects with a specialization in residential design across the country were asked to rate the expected popularity of a variety of residential outdoor design elements. The category of gardens and landscape spaces, with 94.9%t rating somewhat or very popular, was followed closely by outdoor livings spaces at 91.5%, which were defined as kitchen and entertainment spaces. When thinking of gardening, Americans tend toward the practical and sustainable with native plants (86.3%), food/vegetable gardens (81.2%), with over half of them preferred to be organic (61.2 percent), rain gardens (55.6%), and rooftop gardens (38.3%). [5.3.12]

The Sustainable Sites Initiative™ (SITES™) is an interdisciplinary effort by the American Society of Landscape Architects, the Lady Bird Johnson Wildflower Center at The University of Texas at Austin and the United States Botanic Garden to create voluntary national guidelines and performance benchmarks for sustainable land design, construction and maintenance practices - see below for more information. [1.25.12]

The Environmental Protection Agency (EPA) recently initiated a national rulemaking to establish a comprehensive program to reduce stormwater runoff from new development and re-development projects, and make other improvements to strengthen its stormwater program. The EPA announced that during this rulemaking process it will evaluate sustainable green infrastructure design techniques that mimic natural processes to evapo-transpire, infiltrate and recharge, and harvest and reuse stormwater. The EPA asked ASLA to collect case studies on projects that successfully and sustainably manage stormwater. ASLA members responded with 479 case studies from 43 states, the District of Columbia, and Canada. Not only do these projects showcase landscape architecture, they also demonstrate to policymakers the value of promoting green infrastructure policies. Green infrastructure and low-impact development (LID) approaches, which are less costly than traditional grey infrastructure projects, can save communities millions of dollars each year and improve the quality of our nation’s water supply. [10.20.11]

New Sustainable Design 101 resource available for students and teachers from the American Society of Landscape Architects (ASLA). Plants that digest toxic waste, parks built from old building materials, trees that lower utility bills and many other sustainable concepts are part of a new free educational resource from the American Society of Landscape Architects (ASLA) available at In addition to the animations, the resource now includes 20 case studies of sustainable projects of all sizes, including master plans, university campuses, urban farms, green roofs and backyards. Each case study lists the project’s environmental benefits and includes a slideshow with images and descriptions, project facts and a downloadable one-page brief. [5.5.11]

ASLA Headlines Congressional Hearing on the Benefits of Green Infrastructure: David Yocca, FASLA, represented the American Society of Landscape Architects in testifying before the House Transportation and Infrastructure Committee’s Water and the Environment Subcommittee on September 30, 2010 for a hearing entitled “Impact of Green Infrastructure and Low Impact Development on the Nation’s Water Quality, Economy, and Communities.”  Green infrastructure and low impact development approaches and technologies were introduced and their impacts summarized, with greenroofs leading the bullet list. ASLA asks us to take a moment to let your member of Congress know how green infrastructure has provided multiple benefits in your community: Ask your legislators to support HR 4202/S 3561 which would provide localities the tools they need to implement a green infrastructure agenda.  [9.30.10]

The American Society of Landscape Architects (ASLA) announced support for new Senate legislation designed to encourage green infrastructure – a novel, sustainable approach that uses natural systems of trees, plants and soils to manage rainwater instead of the overburdened and outdated infrastructure that currently exists in cities. In most instances, rainwater picks up pollutants as it flows from driveways, parking lots, roofs and roadways before pouring untreated through the sewer system into the nearest watershed or drinking water supply. Introduced by U.S. Senator Tom Udall, the Green Infrastructure for Clean Water Act (S 3561) offers grants and technical assistance for communities to use green roofs, rain gardens and other sustainable approaches that naturally capture and clean the rainwater – often preventing the water from ever entering the sewer system. “Green infrastructure techniques can save cities millions of dollars each year on water management and billions of dollars in infrastructure upgrades. In addition, these natural systems actually remove pollutants from the water while helping clean the air, reduce the urban heat-island effect and lower energy consumption,” said ASLA Executive Vice President and CEO, Nancy Somerville, Hon. ASLA. “We applaud the leadership of Senator Udall for this legislation, and encourage swift action.” The legislation would create between three and five centers around the country to research best green infrastructure practices and provide technical assistance to communities. S 3561 also provides community grants to implement these practices and create a green infrastructure program within the U.S. Environmental Protection Agency. Learn more about the issue at: [7.7.10]

City of Atlanta

The Atlanta City Council has approved significant changes to the "post-construction stormwater ordinance" that will require the use of green stormwater infrastructure to manage stormwater onsite. Going forward, new and re-development sites greater than 500 square feet are required to treat the first inch of stormwater runoff with green infrastructure best management practices including rain gardens, bioswales, permeable paving, green roofs, etc. The ordinance also requires that new homes and large additions of 1000 square feet or more manage the first inch of stormwater runoff with green infrastructure best management practices. This is a huge step forward and puts Atlanta among progressive cities beginning to manage their water with natural infrastructure. [3.4.13] 

City of Austin

On August 27, 2009, Austin City Council charged the Green Roof Advisory Group (GRAG) to work with City staff to explore the feasibility of offering energy and stormwater credits and other incentives, based on performance, to encourage the creation of green roofs in the City. GRAG produced a policy document that included recommendations regarding those credits and incentives that would be appropriate for promoting green roofs in Austin. The stakeholder group was drawn from the fields of design, development, and green building and includes input from local green roof organizations and the Lady Bird Johnson Wildflower Center. GRAG's findings were presented to various City of Austin Boards and Commissions throughout September and October, and the final report to City Council will be on October 28, 2010. Please see the final GRAG Report. [10.28.10]

Austin is moving to make roofs in the city greener. The City Council heard a report from its Green Roof Advisory Group (GRAG) on Thursday, March 25. This was the culmination of the initial phase of research into how green roofs could benefit Austin and how to make it easier for them to flourish in the city. The next phase will determine best practices and develop policy recommendations for the city over the next five years. Green roofs take many forms, but essentially involve vegetation atop building structures. Most any level or near-level roofing structure can be made to support greenery. There are many lightweight solutions for existing roofs, including roll-out systems and shallow modular trays. If a structure is built with green roofs in mind, more substantial plans, including trees, can be included. Austin City Hall was built with an underground parking garage, so the roof of the garage is actually a 12,000 square foot plaza with trees and plants. Eleanor McKinney, a registered landscape architect and licensed green roof professional, chairs the GRAG and presented the report. She said there are nineteen green roofs recorded in the city database of green roofs in Austin. Green roofs provide many benefits to cities. They help mitigate the urban heat island effect, where city temperatures are often up to ten degrees warmer than surrounding areas. They help moderate cooling and heating costs in the buildings they cover by keeping the rooftop temperatures lower and providing another layer of insulation to the building. They extend the life of the roofs they cover. They help improve air quality in the city by absorbing carbon dioxide and producing oxygen. They reduce and filter runoff of rainwater, easing city sewer systems and local creeks.  The GRAG final report will be presented to the city council in August 2010.

City of Baltimore

Baltimore City Proposes to Adopt the International Green Construction Code (IgCC) in 2015 to replace the Baltimore City Green Building Standards. Since July of 2009, new buildings over 10,000 square feet built in Baltimore City have been required to meet the Leadership in Energy and Environmental Design (LEED) standard at a Silver level. LEED is an evaluation system that rates the overall “greenness” of a building by assessing its energy and water efficiencies as well as certain site and interior design strategies. In 2010, the City offered an alternative compliance path by issuing the Baltimore City Green Building Standards, a locally developed alternative to LEED. [11.25.14]  

City of Chicago

As of January 1, 2012, the Department of Environment no longer exists as a standalone unit. The integrated model that replaces it is critical to incorporate sustainability so that it is a part of every policy decision and capital investment. Starting in 2012, each department and sister agency will be engaged in creating a more sustainable Chicago. For more information on the Chicago Center for Green Technology's programs, courses, and volunteer opportunities, please visit: [1.1.12]

City of Cincinnati

The Ohio Environmental Protection Agency, Metropolitan Sewer District of Greater Cincinnati and the Cincinnati Office of Environmental Quality have created the first Green Roof Loan Program of its kind in Ohio. The Ohio EPA has made $5,000,000 available for linked-deposit, below-market-rate loans to install green vegetative roofs within the service area of MSD. These can be installed on residential, commercial and/or industrial buildings. Green roofs have wonderful benefits and have been utilized in Europe for many years to address various climate and aesthetic issues. They absorb rain water, help purify the air and provide additional green space in highly developed areas, especially within urban cores. [12.6.12]

Mayor Seeks Citizen Input on Sustain Louisville Plan for Greener City. Establish a citywide alternative energy strategy. Increase TARC ridership by 25 percent. Develop a citywide green infrastructure program to reduce storm water runoff (implementing a Cool Green Roof program). Improve the energy efficiency of city-owned buildings by 20 percent. Those are some of the 60 initiatives contained in the city’s first comprehensive plan to make Louisville greener and more environmentally friendly. Mayor Greg Fischer today released the draft report of the plan, called Sustain Louisville, and is asking citizens to spend the month of February reading it and providing feedback. That input will be considered before the final report is released in March. [1.31.13]

The Louisville Metro Council unanimously passed an ordinance adopting changes to the Land Development Code via a resolution introduced in March 2011, which Councilwoman Tina Ward-Pugh sponsored. These changes will reward builders and developers for incorporating green building practices into their projects by providing for greater development intensity on qualifying projects. The changes also encourage builders and developers to orient their buildings to account for the sun, to add more windows to reduce energy used on lighting and to reduce surface water runoff by using green roofs or adding open space. [7.29.11]  

City of Milwaukee

MMSD has proposed awarding the 21 public and private property owners a total of $1.35 million in grants to help pay up to 50% of the cost of each project. The district's goal is to encourage property owners throughout the metropolitan area to build 740 million gallons' worth of storage capacity by 2035. The volume is 42% more than the deep tunnel system storage capacity of 521 million gallons. The program is known as Fresh Coast 740, and the district estimates it will distribute $1.3 billion over the next 20 years in grants to its green infrastructure partners. Storm water flowing off parking lots would enter a long swale connected to a rain garden. The system will prevent the water from draining to a combined sanitary and storm sewer there, and reduce pollutants in storm water draining to the canal, a tributary of the Menomonee River. For MMSD, the year 2035 also is the deadline the district has given itself to achieve no sewer overflows. Since 1994, the first full year of deep tunnel system operation, the district has had an average of 2.4 overflows a year of combined sanitary and storm sewers in central Milwaukee and eastern Shorewood. [6.16.14]

Milwaukee Receives EPA Great Lakes Shoreline Cities Green Infrastructure Grant. The U.S. Environmental Protection Agency today announced the award of a $1 million Great Lakes Restoration Initiative grant to the city of Milwaukee to fund green infrastructure projects to improve water quality in Lake Michigan. EPA Region 5 Administrator / Great Lakes National Program Manager Susan Hedman was joined at the Global Water Center by Milwaukee Mayor Tom Barrett to announce the grant. [3.12.14]

The Milwaukee Metropolitan Sewerage District's Commission has approved a Regional Green Infrastructure Plan. Milwaukee is already a recognized national leader in infrastructure, and this plan will keep them at that forefront. Green infrastructure mimics Mother Nature by storing and infiltrating stormwater on the land where the rain falls, making it a resource rather than a nuisance. This can be done with porous pavement, green roofs, rain gardens, rain barrels and bioswales. Implementing the Regional Green Infrastructure Plan will be a monumental undertaking over the coming decades, but the beauty of green infrastructure is that it complements what already exists, builds from the success of our existing infrastructure, naturalizes and beautifies our urban fabric, and can be built in our front and backyards alike. [7.22.13]

The MMSD is providing partnership funding to increase more natural stormwater management practices that capture, store, or filter rainwater. These practices reduce the risk of basement back-ups, flooding, and sewer overflows, and help prevent rain from becoming polluted stormwater runoff, the biggest remaining threat to our rivers and lakes in the United States. The Regional Green Roof Initiative is a cost reimbursement program for eligible green roof expenses for chosen applicants. Awardees will receive up to $5.00 per square foot for their green roof. These projects will provide the District with information related to Green Infrastructure (GI) effectiveness, costs, and maintenance, and help to meet future stormwater capture goals. Application submission period closes on March 29, 2013. [1.16.13]

More rooftops in the Milwaukee area will be enlisted to grow grasses, flowers and other plants now that the Milwaukee Metropolitan Sewerage District (MMSD) has been given the nation's first wastewater discharge permit mandating "green infrastructure" to collect and absorb storm water. The state Department of Natural Resources issued MMSD a new five-year pollution discharge permit this week that requires the district to establish 1 million gallons of so-called green storm-water storage capacity each year. Sewer pipes, bedrock tunnels and concrete reservoirs cannot be used to meet the mandate. A green roof or rain garden can capture up to 3 gallons of rain per square foot. One rain barrel holds 55 gallons. [1.9.13]

The Milwaukee Metropolitan Sewerage District (MMSD) is providing incentive funding to increase green roof coverage within its service area. The Regional Green Roof Initiative will provide up to $5 per square foot of an approved green roof project. The District’s interest in green roofs is to hold rainwater where it falls, thereby diminishing the risk of sewer overflows and improving the overall water quality in the region. In addition to managing stormwater, green roofs offer numerous additional environmental, economic, and social benefits. The application due date is March 30, 2012. [2.19.12]

The Milwaukee Metropolitan Sewerage District (MMSD) is inviting units of government, organizations, school districts, and businesses within the 28 communities it serves to participate in a 2010 Regional Green Roof Initiative Program. Participation in the program will require interested parties to respond to a Request for Proposal (RFP) following standard procedure. The MMSD’s interest in green roofs is in capturing rainwater on our region’s rooftops and keeping it out of our regional sewer system. Doing so will help reduce polluted stormwater runoff and combined and separated sewer overflows to Lake Michigan. For more information you can download the press release from we energies regarding the Initiative along with a Green Roof Program Notice and RFP from MMSD. Read more in Industry Support. [11.9.10] 

City of New Orleans

The Sewerage and Water Board of New Orleans Announces Launch Of A New Green Infrastructure Program. The Sewerage and Water Board of New Orleans is getting a little greener. The Board unveiled seven green infrastructure projects it’s partnering on that aim to improve community outreach and participation in the city’s water management. One of the seven grantees for the Sewerage and Water Board’s green initiative is Rabouin International High School. It plans to build both a blue and a green roof on top of its building in the CBD. Anthony Mayer is the project coordinator. Mayer says blue roof technology means creating a kind of bathtub on top of a building to catch excess rain and storm-water. Unlike most roofs, which let water run straight down, this roof keeps water up high, so it won’t back up sewers and cause floods. [9.26.14]  

City of New York

The goal of the Green Infrastructure Grant Program is to support projects that will reduce the strain of rainwater on the city’s combined sewer system by turning hard surfaces such as concrete into permeable ones such as the soil on green roofs. Applications must be submitted by Nov. 23. New York City is a world leader in protecting the natural environment and fighting climate change and we encourage community groups and non-profits from across the city to apply for the $5 million in new funding we have made available to build green infrastructure projects, DEP Commissioner Emily Lloyd said in a statement. [10.2.14]

The New York City Department of Environmental Protection (DEP) today encouraged community groups, non-profits, and property owners to apply for the $6 million in new funding that is available for green projects through the 2014 Green Infrastructure Grant Program. DEP is engaged in a city-wide effort to soften the impervious urban landscape and help absorb rainwater that would otherwise drain into the combined sewer system and contribute to combined sewer overflows into local waterways. Notable projects that were funded during the first three years of the Grant Program and have completed construction include a 43,400 square foot green roof at the Brooklyn Navy Yard, one of the nation’s first blue/green roof combinations at The Osborne Association in the Bronx, a green roof at Lenox Hill Neighborhood House in Manhattan, permeable pavers and rain gardens at Queens College, a New York Restoration Project community garden in Brooklyn’s Gowanus neighborhood, and a green roof at Bishop Loughlin Memorial High School in Brooklyn. [3.4.14]

The New York property tax abatement for green roofs in New York City is amended to extend the application deadline from March 15, 2013, to March 15, 2018. Beginning with tax years commencing on or after July 1, 2014, and ending on or before June 30, 2019, the tax abatement is increased from $4.50 per square foot to $5.23 per square foot of a green roof, provided that the amount of the abatement does not exceed the lesser of $200,000 (an increase from $100,000) or the tax liability of the eligible building in the tax year in which the abatement is taken. [12.30.13]

The New York City Department of Environmental Protection (DEP) last week issued a Request for Proposals for engineering teams to assist the department in its Green Infrastructure Research and Development Program. In order to improve the cleanliness and health of New York City’s waterways, DEP has embarked on an aggressive campaign to install cost-effective green infrastructure installations throughout the city to manage stormwater that falls on city streets, roofs, and sidewalks. DEP is planning for $2.4 billion in public and private funding for green infrastructure installations by 2030 to significantly reduce the discharges from the City’s combined sewer system which can occur during heavy rain storms. Preliminary monitoring results to date show that pilot installations are meeting or exceeding expectations for absorbing stormwater. Over the next three years, DEP will invest over $187 million in the green infrastructure program and a robust research and development effort is necessary to ensure the success of the program. DEP expects to select an experienced team that is familiar with the New York City green infrastructure program, or a comparable municipality’s program, and can work with DEP to implement an innovative and effective green infrastructure research and development effort for several years. [6.14.13]

City Planning Commission unanimously approves Zone Green proposal. Zone Green is the most comprehensive effort of any city in the nation to sweep aside obstacles to green buildings and energy efficiency – eliminating barriers to green roofs to energy generation and to rooftop agriculture. Zone Green will give homeowners and building owners new opportunities to make investments that save them energy, save them money, and improve our environment. [3.28.12]

The City Planning Commission unveiled a proposal to amend New York City's zoning code to make it easier for buildings to incorporate environmentally friendly additions such as solar panels, wind turbines and wall insulation. New Yorkers spend $15 billion annually to heat and power buildings, contributing 80 percent of the city's carbon emissions. But building owners currently face height and floor area restrictions that can stand in the way of adding energy-saving features on building exteriors. In November, City Planning Commissioner Amanda Burden said her department would soon propose rule changes to do away with these hurdles, but she declined to provide details. The package of rule changes, dubbed Zone Green, would permit solar panels, green roofs, storm water detention systems, skylights and other green features on buildings, despite height restrictions, and would allow owners to install wind turbines up to 55 feet above rooftops on waterfront buildings and buildings taller than 100 feet. Free standing turbines would be permitted on waterfront blocks in commercial and manufacturing areas. The proposal would also loosen restrictions on sun control devices that help provide natural light, exempt greenhouses up to 25 feet from floor area and height limits on non-residential buildings, and specify that electric vehicle charging is allowed in all parking facilities. Building owners could also add external wall insulation without impacting floor area calculations, among other things. The rule changes are subject to a full public review process before the city's community boards, borough presidents and city council. [12.12.11]

Environmental Protection Commissioner Carter Strickland announced up to $4 million in grants as part of the 2012 Green Infrastructure Grant Program to build green roofs, rain gardens, rainwater harvesting, right-of-way bioswales, and similar methods for reducing and managing stormwater on private property and public sidewalks in combined sewer areas. The new round of grants continues to support the PlaNYC goal of improving water quality by reducing the likelihood and intensity of combined sewer overflows. New York City, like other older urban centers, is largely serviced by a combined sewer system where stormwater and wastewater are carried through a single pipe. During heavy storms, the system can exceed its capacity and is designed to prevent treatment plants from washing out by discharging a mix of stormwater and wastewater — called a combined sewer overflow, or CSO — into New York Harbor. Under the 2011 Green Infrastructure Grant Program, DEP awarded $3.8 million in grants to 13 entities out of 52 that applied. [11.21.11]

The New York State Department of Environmental Conservation and the New York City Department of Environmental Protection reached a draft agreement to reduce combined sewer overflows (CSO) into area water bodies, the agencies announced. The agreement modifies New York City's approach to improving harbor water quality, under which the city will invest an estimated $187 million in green infrastructure projects by 2015, part of a planned $2.4 billion public and private investment over the next 20 years. The city will also complete work on approximately $1.6 billion in gray infrastructure projects. [10.19.11]

On Wednesday, New York City Mayor Bloomberg signed into law a bill to exempt rooftop greenhouses from being counted toward a buildings’ height and floor area measurements. The greenhouses will join structures like roof tanks, air-conditioning equipment and chimneys as apparatus that are not factored into buildings’ official totals, easing limitations on the construction of such structures. As for greenroofs, new legislation will allow 4 inch depth systems to be submitted to the NYC Department of Buildings without the need for construction plans or permits. [8.17.11]

Urban forestry grants totaling $966,489 are being awarded to communities and organizations across New York, state Department of Environmental Conservation (DEC) Commissioner Joe Martens announced. The New York State Urban and Community Forestry Program provides technical assistance to communities through local DEC Urban Foresters and ReLeaf volunteers. Financial assistance is available from the state through competitive cost-share grants. "Urban forestry initiatives are key to promoting clean air, clean water, energy savings, habitat creation, and improved quality of life for New York residents," Commissioner Martens, said. "These grants build upon our goals to improve the environment across the state and will have a lasting impact by creating cleaner, healthier communities for both current and future generations to enjoy." [7.25.11]

In the fall of 2009, North Star Fund launched the "Greening Western Queens Fund," a new $7.9 million initiative to invest in energy-efficiency and environmental projects in the Western Queens community affected by a July 2006 electric power outage. This program is supported by funds from the community's settlement with Con Edison. The Public Service Commission of the State of New York selected North Star Fund to administer the project because of our expertise in facilitating community led grant making processes. This includes efforts to improve existing sites, as well as creating new green spaces. Special consideration will be given to the planning and/or creation of green roofs and other newly created green spaces that demonstrate multiple benefits, for example, energy conservation and increased local food production. Examples of community and public sites include: community centers, schools, libraries, etc. To apply for a Greening Western Queens Fund grant, you must submit an application to the North Star Fund by September 12, 2011. [7.25.11]

Environmental Protection Commissioner Cas Holloway announced the 15 winners of DEP's 2011 Green Infrastructure Grant Program. Selected from a total of 52 applications, the 15 winners will share approximately $3.8 million of funds to build green infrastructure projects that will reduce combined sewer overflows and improve water quality in New York Harbor. During heavy storms, the sewer system often reaches capacity and must discharge a mix of stormwater and wastewater — called a combined sewer overflow, or CSO — into the city's surrounding waterways. As part of the NYC Green Infrastructure Plan that calls for investing $1.5 billion over the next 20 years to reduce sewer overflows, the grant program enables the city to partner with community organizations, businesses and not-for-profits to address stormwater runoff from private property. The grants will be used for a wide variety of innovative and creative stormwater controls, including green roofs, blue roofs, porous concrete, bioswales, and other measures to reduce and manage as much as 5.7 million gallons of stormwater a year. [6.11.11]

DEP announces $3 Million in community-based Green Infrastructure Program grants. Environmental Protection Commissioner Cas Holloway announced up to $3 million in grants this year for green infrastructure projects within combined sewer overflow drainage areas in New York City as part of the NYC Green Infrastructure Plan. The grants can be used for green roofs, enhanced tree pits, and other measures to reduce and manage stormwater on private property and public sidewalks. The launch of the grant program fulfills a 2011 State of the City commitment made by Mayor Bloomberg last month, and helps achieve the PlaNYC goal of improving water quality. [2.2.11]

DEC Accepting Applications for Urban Forestry Grants: Tree Plantings, Green Infrastructure Can Reduce Pollution, Improve Urban Quality of Life. The New York State Department of Environmental Conservation (DEC) announced it is making grants available to support urban forestry projects across the state. The Urban and Community Forestry grants will enhance New York's urban landscapes with healthy trees and provide numerous environmental, health and economic benefits. Eligible projects include tree inventories and management plans, tree and shrub planting and maintenance, and green infrastructure projects such as green roofs and rain gardens. [12.8.10]

Yesterday, New York City’s Department of Environmental Protection released a proposed “NYC Green Infrastructure Plan” to integrate green infrastructure into the city’s efforts to combat Combined Sewer Overflow. The Plan presents an alternative approach to improving water quality, integrating swales and green roofs, among others, with investments to optimize the existing system and to build targeted, cost-effective “grey” or traditional infrastructure. [9.28.10]

City of North Vancouver

The City of North Vancouver has introduced new incentives and requirements for all new construction. In addition, amendments to the City's Zoning Bylaw will provide more opportunities to include higher energy efficiency, waste and water diversion, local food production and healthy living environments into construction design. A summary of the zoning amendments, which was presented at a public meeting on October 20, 2014, included the following changes: Solar roofs, green roofs: Solar collector height exemption (four feet for ground-oriented residential and six feet for all other zones) and green roof exemption (1.5 ft for ground-oriented residential and up to 3.5 ft for all other zones). [11.10.14]  

City of Philadelphia

The Philadelphia Water Department (PWD) and the Philadelphia Industrial Development Corporation (PIDC) have awarded $4.7 million in grants to promote green stormwater management practices in a highly competitive selection process. Launched in January 2012, the Stormwater Management Incentives Program (SMIP) grant program is designed to be a catalyst for transforming large, commercial impervious properties that generate high volumes of stormwater runoff and burden the City’s sewer system and waterways into properties that build and maintain green stormwater management practices. These practices include rain gardens, vegetated infiltration basins, porous asphalt, and green roofs. [10.9.13]

Mayor Michael A. Nutter and the Mayor’s Office of Sustainability released the Greenworks Philadelphia Update and 2012 Progress Report, marking the midway point in the plan’s goal for Philadelphia to be the greenest city in America by 2015. Of the 167 initiatives put forth in Greenworks, 38 initiatives are complete, and 110 are currently underway. For the first time, this year’s progress report features metrics for each of the plan’s measurable targets. Progress toward two thirds of the targets is on track, and two of the target goals, Targets 7 and 9, are exceeding expectations. Target 7 is to divert 70% of solid waste from landfill; the City has exceeded that and is now aiming higher. Target 9 was to provide Park and Recreation resources within 10 minutes of 75 % of residents; the City accomplished that and now is aiming to provide walkable access to Park and Recreation Resources for all residents. [6.18.12]

On June 1, the PA Department of Environmental Protection and the Philadelphia Water Department signed a groundbreaking agreement that will allow PWD to officially implement its Green City, Clean Waters plan. PWD plans to spend approximately $2 billion over the next 25 years to use largely green infrastructure (stormwater tree trenches, porous paving, rain gardens, sidewalk planters) to transform manmade surfaces that repel the rain into green acres that capture, infiltrate and manage rainwater runoff—just like Mother Nature. [6.1.11]

The City of Brotherly Love, aiming to become America's greenest, has joined other U.S. cities in requiring energy-efficient reflective roofs for new buildings. Philadelphia's "Cool Roof" bill, signed into law last month by Mayor Michael Nutter, follows similar steps taken in Chicago, California and New York, according to Builder magazine. Unlike traditional black asphalt roofs, cool ones (often white) reflect the sun's rays back into the atmosphere and release absorbed heat. This keeps buildings cooler, reducing the demand for air conditioning by 10% to 30%. "This legislation is a simple step to reduce energy consumption and is virtually cost-neutral for new construction," its sponsor Councilman Jim Kenney said at a press conference overlooking Philadelphia's City Hall from the white roof of 1515 Market Street. The new law, which applies to all new buildings with little or no roof slope, will likely affect only row houses and commercial buildings. Not many single-family homes have flat or near-flat roofs. The law, which exempts projects with vegetative roofs and those with rooftop photovoltaic panels, is part of Philadelphia's plan to become the "greenest city in America" by reducing its energy consumption 10% and retrofitting 15% of its housing stock by 2015. To get started, Nutter also announced that all homes on the 1200 block of Wolf Street won the "Coolest Block" contest and will receive energy efficient upgrades that include a cool roof, air sealing and insulation. The Dow Chemical Company is helping fund the project. [6.3.10]

City of Portland, ME

The City of Portland, ME, will release new details this week of a plan to charge property owners a stormwater fee for the amount of pavement, roof coverage and other hard surfaces on their land. Both homeowners and business owners will pay, although businesses with large parking lots and building footprints -- and that shed more rainwater -- will get hit harder than other landowners. The details include a preliminary estimate of the future stormwater rate, which will raise money for costly projects to keep dirty storm runoff out of waterways. The fee structure and timeline for rolling it out are still being discussed by the City Council's Finance Committee, and the actual rates ultimately must be set by the full City Council. The fee was intended to kick in this winter, but the launch is now expected to be pushed back. The fee can be reduced for properties whose owners install rain barrels, rain gardens, green roofs and commercial treatment centers. See the City of Portland, Maine's Proposed Stormwater Service Charge FAQs. [9.23.13] 

City of Portland, OR

International recognition for Portland’s Ecoroof Program. Portland’s reputation as a leader in ecoroof technology continues to grow. The city has received a 2013 Green Roof Leadership Award for Municipalities from the International Green Roof Association (IGRA). Portland received the award at the 3rd International Green Roof Congress held in May in Hamburg, Germany. Over 250 participants from more than 40 countries attended to learn about future trends for roof and façade greening. “It’s great for the city that Portland is receiving international recognition for our innovative stormwater management,” said City Commissioner Nick Fish. “Ecoroofs have many benefits, and one of the main benefits is that they make the sewer system more efficient and reliable by acting like giant sponges soaking up rain and keeping stormwater runoff out of our sewers.” The association noted that Portland’s work to promote green roofs is encouraging other cities around the world to adopt the technology to manage stormwater. “We’re honored to receive this award,” said Bureau of Environmental Services Director Dean Marriott. “And we are pleased that our efforts to promote green roofs are being recognized.” Green roofs replace conventional roofing materials with soil and vegetation. They manage stormwater onsite and provide many other human health and environmental benefits. Over 500 green roofs cover more than 1.5 million square feet of rooftop in the City of Portland. [6.11.13]

The Portland Ecoroof Symposium to examine the ecoroof business case. The costs and savings of ecoroofs is the focus of the Portland Ecoroof Symposium on Thursday, May 2, 2013 at the World Trade Conference Center in downtown Portland. Speakers and presenters will discuss the bottom line on green rooftops in Portland, and present scientific research and case studies that explore the economics of ecoroofs. The event is targeted toward architects, landscape architects, developers, building owners and facility managers. The symposium also features a vendor showcase of leading green roof companies from Portland and the surrounding region. Registration for the event is $25 and includes lunch. The registration deadline is Friday, April 26th. Go to for more information. Ecoroofs are vegetated roof systems that absorb rain to reduce stormwater runoff, improve air quality and save energy. There are currently 382 ecoroofs in Portland covering over 19 acres. [4.23.13]

The BES Ecoroof Program provides technical assistance, trainings, design innovation, monitoring, and ecoroof research. Since the onset of the Grey to Green Initiative in 2008, the ecoroof incentive has allowed us to contribute $2 million to 160 projects for close to 10 acres of ecoroof. Through these projects we've seen innovations developed, new partnerships formed, and steady growth in the local green roof industry. The city is in the process of setting its budget priorities for the 2013-14 fiscal year. There is a possibility that the ecoroof incentive will be discontinued. Applications for the ecoroof incentive are currently being accepted but may not be awarded pending budget discussions over the next few months. Applications will be evaluated against available resources. Be assured that the Ecoroof Program itself will continue. The next Ecoroof Symposium will take place on Thursday, May 2, 2013. This year's Symposium will take a closer look at return on investment, with a focus on the design and development communities. We hope to use that opportunity to celebrate what has been accomplished and engage the audience in a discussion about next steps. I hope you'll be able to participate in that discussion. [1.31.13]

Portland Bureau of Environmental Services will begin accepting applications again in October 2012 for ecoroof construction. The City of Portland offers an incentive to property owners and developers to add more ecoroofs. The incentive program is part of Portland's Grey to Green initiative to increase sustainable stormwater management practices, control non-native, invasive plants, and protect sensitive natural areas. The incentive funds up to $5 per square foot of an ecoroof project. Installation costs for ecoroofs in Portland range from $5 to $20 per square foot. [10.1.12]

Portland Ecoroof Symposium - The Bottom Line on Portland Green Rooftops, Portland, OR. Cities across the world are investing in green roofs to combat urban challenges. Portland is a leader in green roofs, and we’ve learned a great deal about their benefits for managing stormwater and greening our city. But more and more is being learned about the true costs and benefits of greenroofs and how they offer a better return on investment. On May 18 join the City of Portland for a series of presentations and case studies that present current research examining the green roof bottom line. [5.18.12]

Portland has again topped the 100,000 square foot mark for new greenroof construction in a calendar year. 2011's total is just a hair over the mark and comprises the green, vegetated portions of ecoroofs and roof gardens constructed within the City limits. There's likely a bit more out there as this comprises only projects which City staff are aware of. Thank you and congratulations to everyone involved in the industry and we look forward to setting a new record this year.

After three months of tweaking, the city’s fifth Regulatory Improvement Code Amendment Package has been approved by Portland City Council. Approved at a recent council meeting, RICAP 5 addresses outdated codes on the proper installation of solar panels, wind turbines, eco-roofs, rain or grey water cisterns and other sustainable technologies. In addition, it provides for larger Accessory Dwelling Units, where a smaller building is constructed alongside an existing residence. ADU’s are considered a more sustainable housing option since they use existing land and require fewer materials to build than single family homes. Under the new code, ADUs can be 75 percent the size of the main unit or a maximum of 800 square feet. [3.11.10]

The City of Portland sponsored Ecoroof Portland on March 12-13, 2010. Attendees learned how ecoroofs work, why they're important, and what's next for Portland's rooftops and skyline. The City has nearly 200 ecoroofs and an incentive available to help with the costs - if you own property in Portland, manage or own development projects, aspire to work in the ecoroof industry, or just support things sustainable, the yearly Ecoroof Portland is the event to get involved with this alternative roofing approach. Activities included Portland ecoroof tours, live ecoroof installations, presentations by local and national experts, and workshops to help you get started on your own project. Fair attendance is always free and vendors can reserve booth space very economically. In addition to Dr. David Sailor of Portland State University and others, Ed Snodgrass, Patrick Carey, and Linda Velazquez spoke at Ecoroof Portland 2010.  Learn more here.

Part of Portland's Grey to Green initiative to increase sustainable stormwater management practices, control non-native, invasive plants, and protect sensitive natural areas, over $800,000 will be spent on the incentive in this fiscal year, and will make funds available over the next three years. You could receive $5 per square foot to build your ecoroof! Applications of incentive applications will be available in April 2010 for the next cycle that begins in the summer of 2010.  Read more under Industry Support.

City of San Francisco

The City of San Francisco’s Green Building Ordinance (GBO) and related policies was named the winner of the World Green Building Council’s Best Green Building Policy Award. A joint venture led by URS Corporation provided significant guidance during the ordinance’s preparation by the San Francisco Department of the Environment. Evidence of the city’s commitment to green building includes the URS joint venture’s design and implementation of the city’s newest “living roof” at One South Van Ness Ave. The 10,000 square foot living roof adds insulation to the building, reduces stormwater runoff and features native plants that provide habitat for hummingbirds and butterflies. The project team also participated in San Francisco’s JobsNow training program by instructing interns on plant identification, irrigation control and weeding techniques. [12.19.11]

City of Seattle

The city of Seattle and King County have agreed to make a total of $1.46 billion in sewer-system upgrades to reduce the amount of polluted water that enters Puget Sound and other waterways, under settlements reached with the federal government. The settlements resolve claims by the U.S. Environmental Protection Agency (EPA) and the state Department of Ecology that the county and city violated the federal Clean Water Act by discharging raw sewage and other pollutants into local waters. The consent decree was negotiated over several years by local, state and federal officials and was filed Tuesday in U.S. District Court in Seattle. The settlements allow the county and city greater flexibility to use so-called green infrastructure such as green roofs, rain gardens and bioswales to improve water quality. [4.16.13]

The Washington Department of Ecology has released its draft draft plan for beefing up its low-impact development requirements for controlling polluted stormwater runoff -- which is considered the top environmental threat to the Puget Sound and many other Northwest lakes, rivers, and streams. This policy change is a big deal. It's trying to solve one of the region's top environmental and health challenges, perhaps second only to climate change and ocean acidification in importance to our area. And what's approved in the coming months will be on the books for a long time. [10.12.10]

The Emerald City is living up to its name, according to a new study which found that half of all new commercial structures here are designed with planted rooftops. With 62 green roofs already built—359,375 square feet, about the size of nine football fields—Seattle is a national leader in the field. The report found that the rate of new green roof installation has increased nearly every year in Seattle since 2001 and the design and installation business sector has also consistently expanded during this time. The study also created the first self-guided walking tour of green roofs in North America, which will allow residents and visitors to explore the hidden gems of our urban ecosystem. [9.23.10]

City of Toronto

The City of Toronto has expanded their Eco Roof Incentive Program by adding the eligibility of residential roofs and increasing the incentive amount for the green roof grant to $75 per square metre. Introduced in 2009, the initiative aims to reduce energy consumption and emissions. One of the updates to the program increases the green roof grant to $75 per square metre to maximum of $100,000. The amount for cool roof grants remains the same at two dollars per square metre to coat over an existing roof and five dollars per square metre to cover a new roof. The grant has a $50,000 maximum. [8.21.13]

Toronto's City Planning division has produced a new resource called Guidelines for Biodiverse Green Roofs, detailing best practices for promoting biodiversity on green roofs in Toronto. The guidelines provide a comprehensive list of plants suitable for green roofs that encourage biodiversity, outline recommended growing media depths and composition and provide ideas for creating habitat aimed at specific species. The document recognizes that green roofs are part of a larger urban ecosystem and provides design strategies for creating appropriate adjacent eco zones alongside existing natural heritage features. These guidelines support and expand the current Toronto Green Roof Construction Standard and are primarily designed for use by architects and landscape architects but may also be of interest to others.  [3.19.13]

Toronto is the first City in North America to have a bylaw to require and govern the construction of green roofs on new development. It was adopted by Toronto City Council in May 2009, under the authority of Section 108 of the City of Toronto Act. The Bylaw applies to new building permit applications for residential, commercial and institutional development made after January 31, 2010 and will apply to new industrial development as of April 30, 2012. [3.30.12]

According to Green Roofs for Healthy Cities, the City of Toronto’s award winning Green Roof Bylaw has already resulted in more than 1.2 million square feet (113,300 square meters) of new green space planned on new commercial, institutional, and multi-unit residential developments across the City. By the way, make sure to apply now for the City of Toronto’s Eco-Roof Incentive Program at Live green Toronto - funding ends December 31, 2011. [9.30.11]

The District Department of the Environment (DDOE) today finalized a new regulatory framework for stormwater management by large development sites in the District of Columbia. The new regulations are published in the DC Register today, Friday, July 19, 2013. This comes in advance of a federal requirement for the District to update its stormwater regulations by July 22, 2013. The new framework includes stormwater retention performance standards that will dramatically reduce stormwater runoff’s harmful impacts to the Anacostia and Potomac Rivers, Rock Creek, and their tributaries. It also includes an innovative Stormwater Retention Credit (SRC) trading program, which is the first of its kind in the nation and has the potential to increase the new standards’ benefit to District waterbodies while reducing the cost of compliance and providing other sustainability benefits. Under the rule, large construction sites that trigger the requirements will install green roofs, rain gardens, permeable pavement, and other green infrastructure practices to reduce stormwater runoff. Stormwater runoff erodes District stream banks and carries trash, oil, pet waste, and other pollutants into District waterbodies. [7.19.13]

The District of Columbia is a national leader in the total amount of Green Roofs constructed - second only to Chicago, IL in the total area of green roofs per capita – and need your help getting to number one! The District’s Green Roof Rebate Program is the perfect way to fund your green roof - and it’s now is back in full swing. AWS is offering $5 per square foot on a first-come, first-served basis for qualified DC buildings of any size! This program is available for residential, commercial and institutional properties. Green Roofs provide numerous ecological, health and economic benefits. The owner of a green roof can benefit from lower energy costs, extended roof-life, fee/tax credits, and increased property values.

EPA Releases Planning Resource to Help Communities Manage Stormwater and Wastewater with Green Infrastructure. EPA has released “Greening CSO Plans: Planning and Modeling Green Infrastructure for Combined Sewer Overflow (CSO) Control,” to provide municipalities and sewer authorities with tools to help quantify green infrastructure contributions to CSO control plans. Communities with combined sewers often view green infrastructure as an attractive way to reduce stormwater flows going into their sewer system, thus helping to reduce capital and operational costs at publicly owned treatment works. Greening CSO Plans will help communities make cost-effective decisions to maximize water quality benefits. The resource explains how to use modeling tools such as EPA’s Storm Water Management Model (SWMM) to optimize different combinations of gray and green infrastructure to reduce both sewer overflow volume and number of overflow events. [3.7.14]

The U.S. Environmental Protection Agency (EPA) announced nearly $5 million dollars in grants to five universities to evaluate innovative green infrastructure practices in urban areas, using Philadelphia, Pa. as the pilot area. These grants stem from a cooperative partnership between EPA and Philadelphia’s Green City, Clean Waters program that represents a broad, long-term investment in implementing green infrastructure stormwater management practices. Philadelphia is a national leader among cities around the country in using green infrastructure to address problems from combined sewer overflows (CSOs). Green infrastructure is a cost-effective and innovative approach to reduce runoff from overflowing combined sewer systems in urban areas. The goal of green infrastructure is to retain or redirect water into the ground where plants and soil will naturally filter the water – avoiding CSOs and reducing violations of the Clean Water Act. Green infrastructure investments also make our communities cleaner, healthier, and more attractive places to live and work. [1.21.14]

EPA Releases Report on Economic Benefits of Green Infrastructure. This EPA report summarizes 13 economic benefit analyses conducted by public entities across the US to assess the effectiveness of their green infrastructure programs.

The Onondaga Environmental Institute will use a $60,000 EPA grant to train people in Syracuse to develop, build, install and maintain controls on stormwater using green infrastructure. Green infrastructure is an approach to water management that protects, restores, or mimics the natural water cycle and enhances quality of life for communities. The Onondaga Environmental Institute will sponsor two green Infrastructure training workshops for low-income, unemployed adults at the L&M Training Center in Syracuse’s southside. Participants will be taught to create and maintain green infrastructure, including rain gardens, bioretention basins, rain barrels and green roofs. In addition, the program will include training on life skills, job readiness, workplace safety and exposure to a variety of “green” careers. [8.8.13]

The U.S. Environmental Protection Agency has invited the 22 largest U.S. Great Lakes shoreline cities to apply for Great Lakes Restoration Initiative funding for green infrastructure projects that will improve Great Lakes water quality. “These Great Lakes Restoration Initiative grants will be used for green infrastructure projects to reduce urban runoff and sewer overflows that foul beaches and impair Great Lakes water quality,” said Great Lakes National Program Manager Susan Hedman. Eligible cities can use the grants to cover up to 50 percent of the cost of rain gardens, bio-swales, green roofs, porous pavement, greenways, constructed wetlands, stormwater tree trenches and other green infrastructure measures installed on public property. Detailed eligibility requirements are available at [7.26.13]

The EPA has launched a National Stormwater Calculator to help property owners, developers, landscapers and urban planners make better land-use decisions to protect local waterways from pollution caused by stormwater runoff. The calculator, which is phase I of the Stormwater Calculator and Climate Assessment Tool package announced in President Obama’s Climate Action Plan, is a desktop application that estimates the annual amount of stormwater runoff from a specific site, based on local soil conditions, slope, land cover, and historical rainfall records. Users can enter any US location and select different scenarios to learn how specific green infrastructure changes — including green roofs, rain harvesting and porous pavement — can prevent pollution. This information helps users determine how adding green infrastructure can be one of the most cost-effective ways to reduce stormwater runoff. [7.24.13]

Decisions about how and where we build our communities have significant impacts on the natural environment and on human health. Cities, regions, states, and the private sector need information about the environmental effects of their land use and transportation decisions to mitigate growth-related environmental impacts and to improve community quality of life and human health. In 2001, EPA published Our Built and Natural Environments: A Technical Review of the Interactions Between Land Use, Transportation, and Environmental Quality to show how development patterns affect the environment and human health. Since then, research has continued to clarify and better explain these connections. To capture this research, EPA has revised and updated the report, incorporating key findings from hundreds of studies. Current patterns of land use, building, and travel behavior have affected the environment in many ways. EPA's Smart Growth Program invites you to participate in a webinar on Wednesday, July 24, from 2:00 - 3:00 Eastern that examines how we could reduce those impacts as our nation's population grows. The webinar will provide an overview of EPA's recent report. [6.19.13]

The value of the assistance available to each project will be approximately $50,000 - $100,000. Letters of interest must be received by April 6, 2012. [2.21.12]

The Department of Justice and the U.S. Environmental Protection Agency (EPA) announced a Clean Water Act (CWA) settlement with the Metropolitan Water Reclamation District of Greater Chicago (MWRD) to resolve claims that untreated sewer discharges were released into Chicago area waterways during flood and wet weather events. The settlement will safeguard water quality and protect human health by capturing wet weather flows entering the combined sewer system, which services the city of Chicago and 51 communities. This consent decree requires MWRD to invest in green roofs, rain gardens and other green infrastructure to prevent basement flooding in the neighborhoods that are most severely impacted by sewer overflows, said EPA Region 5 Administrator Susan Hedman. The enforceable schedule established by this consent decree will ensure completion of the deep tunnel and reservoir system to control untreated sewage releases into Chicago area rivers and Lake Michigan. [12.14.11]

The US Environmental Protection Agency (EPA) and the General Services Administration (GSA) have joined forces to promote the Federal Green Challenge Initiative in New England federal facilities. The Federal Green Challenge Initiative is a voluntary program designed to help federal agencies improve operating efficiency and reduce their environmental footprint. GSA’s goal is to reduce the environmental footprint of New England federal facilities by at least five percent annually in a minimum of two of the following areas: waste, electronics, purchasing, transportation, water and energy. [11.17.11]

U.S. Environmental Protection Agency (EPA) announced a commitment to using an integrated planning process to help local governments dealing with difficult financial conditions identify opportunities to achieve clean water by controlling and managing releases of wastewater and stormwater runoff more efficiently and cost effectively. The integrated planning process, outlined in a guidance memo to EPA’s regional offices from EPA’s Office of Water and Office of Enforcement and Compliance, will help municipalities prioritize infrastructure investments to address the most serious water quality issues and provide flexibility to use innovative, cost-effective stormwater and wastewater management solutions. Integrated planning approaches can also have other benefits, like leading to the identification of innovative, sustainable solutions that improve water quality and enhance community vitality. Green infrastructure, such as green roofs, rain gardens, planter boxes, and permeable pavement, is an example of an integrated solution that can reduce, capture, and treat stormwater runoff at its source before it can reach the sewer system. Green infrastructure provides a cost effective way to reduce overflows and add green space in communities. [10.28.11]

The Metropolitan St. Louis Sewer District (MSD) has agreed to make extensive improvements to its sewer systems and treatment plants, at an estimated cost of $4.7 billion over 23 years, to eliminate illegal overflows of untreated raw sewage, including basement backups, and to reduce pollution levels in urban rivers and streams, the Department of Justice and the U.S Environmental Protection Agency (EPA) announced. The settlement will also significantly advance the use of large scale green infrastructure projects to control wet weather sewer overflows by requiring MSD to invest at least $100 million in an innovative green infrastructure program, focused in environmental justice communities in St. Louis. Examples of potential green infrastructure projects include green roofs, bioretention, green streets, rain barrels, rain gardens and permeable pavement. [8.5.11]

The U.S. Environmental Protection Agency (EPA) is launching a new strategy to promote the use of green infrastructure by cities and towns to reduce stormwater runoff that pollutes our nation’s streams, creeks, rivers, lakes and coastal waters. Green infrastructure decreases pollution to local waterways by treating rain where it falls and keeping polluted stormwater from entering sewer systems. In addition to protecting Americans’ health by decreasing water pollution, green infrastructure provides many community benefits including increased economic activity and neighborhood revitalization, job creation, energy savings and increased recreational and green space. Stormwater is one of the most widespread challenges to water quality in the nation. Large volumes of polluted stormwater degrade our nation’s rivers, lakes and aquatic habitats and contribute to downstream flooding. Green infrastructure captures and filters pollutants by passing stormwater through soils and retaining it on site. Effective green infrastructure tools and techniques include green roofs, permeable materials, alternative designs for streets and buildings, trees, rain gardens and rain harvesting systems.

Green Roofs for Stormwater Runoff Control - Urban development has led to large areas of impervious surfaces such as parking lots and building roofs, and runoff from these areas is causing problems for many urban and suburban communities. Green roofs have been suggested as a means to reduce the stormwater impact and test results indicate that green roofs are capable of removing 50% of the annual rainfall volume from a roof through retention and evapotranspiration. [12.7.10]

The U.S. Environmental Protection Agency announced that it has issued a proposed permit to the District of Columbia requiring the District to continue improving its Municipal Separate Storm Sewer System (MS4) program for controlling stormwater runoff. EPA is accepting comments on the permit until June 4. “The innovations in this new permit are vital to restoring and protecting the health of local waterways in the District, as well as the Chesapeake Bay,” said Shawn M. Garvin, EPA mid-Atlantic Regional Administrator. “We all need to do our part, and this permit can serve as a model to other municipalities for preventing runoff from washing harmful pollutants into streams and rivers in the Bay watershed.” Medium and large MS4s such as the District’s are required by federal law to have permits covering their discharges. The permit announced requires the District to take progressive steps that were not required by the old permit issued in 2004, including: Implementing a sustainable and enforceable approach to promoting low impact development and green infrastructure, including enhanced tree planting, green roofs, and water reuse onsite to slow down the rate of runoff from paved areas of the District.

Reducing Urban Heat Islands: Compendium of Strategies: Urban areas are usually warmer than their rural surroundings, a phenomenon known as the “heat island effect.” As cities develop, more vegetation is lost and more surfaces are paved or covered with buildings. The change in ground cover results in less shade and moisture to keep urban areas cool. Built-up areas also evaporate less water, which contributes to elevated surface and air temperatures. Properties of urban materials, in particular solar reflectance, thermal emissivity, and heat capacity, also influence the development of urban heat islands, as they determine how the sun’s energy is reflected, emitted, and absorbed. Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality. [10.1.08] (Federal Business Opportunities)

Green Infrastructure Ontario Coalition (GIO)

Cities need living green infrastructure as well as grey. The federal government has made a strong commitment to funding infrastructure across Canada with its announcement of $14B over 10 years from the Building Canada Fund. Getting the most from our investments in national infrastructure, however, requires including support for living green infrastructure as well as traditional grey infrastructure. Increased investment in grey infrastructure like roads and transit is much needed, but Canada is falling behind countries like the United States in funding living green infrastructure. The current focus on grey infrastructure should not dictate how infrastructure is conceived for the next 10 years. Living green infrastructure is a different way of thinking about infrastructure. It is a multi-scale network of ecological features that provide a wealth of benefits to our communities. Living green infrastructure includes everything from natural vegetative systems such as tree-lined streets or urban parks, to green technologies such as green roofs and permeable pavement. All of these elements combine to form a natural network that helps clean our air and water. [2.18.14]

A new report released by the Green Infrastructure Ontario Coalition identifies green infrastructure as a cost solution policy makers should be considering on the eve of the Ontario Budget and in subsequent political discussions centered on doing more with less. Health, Prosperity and Sustainability: The Case for Green Infrastructure in Ontario argues taxpayer dollars spent on green infrastructure offer a greater return on investment because of the multiple economic, health and environmental benefits. The report, co-written by the Coalition and Ecojustice, examines how other jurisdictions in North America are leveraging the rewards from public policies and investments in green infrastructure, and makes specific, practical recommendations to the provincial government on how to similarly benefit.

NASA (National Aeronautics and Space Administration)

NASA plays an increasingly important role in research into climate change and its potential impacts on the quality of life on earth. This includes several thrusts of research into the impact on urban life on climate change. One such effort at NASA involves utilizing green (a.k.a. vegetated) roofs. NASA’s research reveals that roofs covered with vegetation provide a cleaner environment, energy savings, and increased insulation. Additionally, utilization of green roofs can dramatically reduce the surface temperature of urban environments, something critically important for elderly and other sensitive populations.

NASA has released a fact sheet detailing efforts to research, use, and improve upon the concept of "green roofs" - urban rooftops covered with vegetation. Although the idea is centuries old, it has great relevance in addressing today's challenges. With over half of the entire human population living in cities, it is important to understand how cities can be affected by climate change, and to devise strategies to employ adaptation strategies to deal with possible impacts.

NRDC (Natural Resources Defense Council)

A new NRDC report released today, The Green Edge: How Commercial Property Investment in Green Infrastructure Creates Value, details the following benefits, which help to build the business case for commercial real estate owners to invest in green infrastructure: increased rents and property values, increased retail sales, energy savings, local financial incentives (such as tax credits, rebates, and stormwater fee credits), reduced infrastructure costs, reduced flood damage, reduced water bills, increased health and job satisfaction for office employees, and reduced crime. [12.17.13]

NRDC has released an update to its 2011 report Rooftops to Rivers II, which showed how cities of all sizes were employing green infrastructure to solve their stormwater pollution problems and revitalize their communities. It showcases how 20 cities were using green infrastructure to better manage stormwater and achieve a host of non-water benefits, including capital and maintenance cost savings.  [10.30.13]

Installing green roofs and cool roofs in southern California could save consumers more than $211 million in energy bills and reduce emissions equivalent to removing 91,000 cars from the road each year, according to a new study from the Natural Resources Defense Council and the Emmett Center on Climate Change and the Environment at UCLA School of Law. Installing green roofs will additionally reduce stormwater runoff that pollutes our beaches. According to the report, “Looking Up: How Green Roofs and Cool Roofs Can Reduce Energy Use, Address Climate Change, and Protect Water Resources in Southern California,” if green roofs or cool roofs were installed on 50 percent of existing roof surfaces for residential, commercial, and government and public use buildings in southern California, it could save up to 1.6 million megawatt hours of electricity annually, enough energy to power more than 127,000 homes in California and save residents up to $211 million in energy costs each year based on 2012 rates. The energy savings would cut carbon pollution by 465,000 metric tons annually. [6.13.12]

NRDC released a new report on how local and state governments can stimulate potentially billions of dollars of private investment, to offset the costs of repairing our nation’s broken stormwater infrastructure. It’s worth a read for policymakers, investors, and anyone who receives a wastewater or stormwater bill from a local utility. In other words, anyone concerned with how municipalities and wastewater utilities will pay for much-needed water infrastructure investments. Our new report, titled “Financing Stormwater Retrofits in Philadelphia and Beyond,” uses the City of Brotherly Love as a test case to explore how innovative financing mechanisms, currently being used for energy efficiency retrofits, can be adapted to the stormwater management context. [2.1.12]

NRDC releases new report, Rooftops to Rivers II: Green Strategies for Controlling Stormwater and Combined Sewer Overflows. It looks at 14 cities, big and small, that are choosing to use green infrastructure as a cost-effective means to reduce the flooding and water pollution caused by both extreme and everyday storms. By building out and encouraging features such as green roofs, porous pavement, rainwater cisterns and roadside plantings, which help absorb rainfall, these cities will be better prepared to handle excess stormwater. The conventional stormwater infrastructure of piping and underground storage allows 10 trillion gallons of water to roll off rooftops, parking lots and roads each year, carrying garbage, pet waste, and oil and gas drippings directly into local water bodies. Green infrastructure, on the other hand, absorbs rain right where it falls, keeping water out of overburdened sewer systems, mitigating flooding and reducing water pollution. It can even help turn costly stormwater into usable water for the community. [11.17.11]

SERF (Society of Environmentally Responsible Facilities)

SPRI (Single Ply Roofing Industry)

For the past three and a half years, Kelly Luckett, President of Green Roof Blocks and Chairman of the Technical Committee for Green Roofs for Healthy Cities, has been working with the Single Ply Roofing Industry to develop the ANSI/SPRI RP-14 Wind Design Standard for Vegetative Roofing Systems. The standard represents a consensus of over 50 industry experts and stakeholders and received approval as an American National Standard on June 3rd, 2010, from the American National Standard Institute (ANSI). The standard will be submitted for inclusion in the International Building Code as a provision in a new section of the building code entitled IGCC: Safe and Sustainable by the Book. The complete standard, in addition to the supporting wind tunnel testing report, is available for downloading from Green Roof Block's website,, and at

RP-14 was developed as a result of the concerns raised by the roofing industry that there has been a lack of consideration regarding the risk of wind damage on vegetative green roof systems . The building code now requires green roofs to have the same wind and fire resistance as a traditional roof. RP-14 provides the industry with a means of meeting the wind resistance portion of this requirement. According to Kelly Luckett, "In order to get this done, we were forced to take a hard look at the way we had been designing green roofs in North America over the past decade. We found specific risks that can be minimized through prudent design precautions. RP-14 establishes minimum design standards that make compliance criteria clear for both green roof providers and code enforcement officials". [6.24.10]

State of Alaska

Stormwater management techniques are also called low impact development or green infrastructure. These techniques use plants and bioengineered landscape features to manage stormwater runoff on-site, filter out debris and pollutants, protect salmon habitat, and keep drinking water clean. Green roofs provide a vegetative cover instead of an impervious surface. Vegetation absorbs runoff that can pollute waterways and cause problems with flooding and erosion. A new green roof incentive has been unveiled in the Matanuska-Susitna Borough in Alaska. The Mast-Su LID Program offers to match half of the cost of a green roof, up to a maximum reimbursement of $500. Click here for more information. [10.11.12]  

State of Illinois (EPA)

Governor Pat Quinn announced more than $5 million in investments to 13 communities across Illinois for green infrastructure improvement projects.

State of New Jersey

Legislation sponsored by Assembly Democrats Wayne DeAngelo, Nancy Pinkin, Tim Eustace and L. Grace Spencer designed to encourage the creation of environmentally friendly buildings was recently approved, 71-3, by the Assembly. The bill (A-2305) aims to promote the incorporation of blue and green roofs into the design of new and existing buildings. Blue and green roofs use vegetation or mechanical devices to prevent roof water from draining too quickly, not only to improve storm water management but also to provide cost saving opportunities such as more efficient energy usage for heating and cooling. [12.17.14]

A two-bill package sponsored by Assembly Democrats Ruben Ramos, Jr., John McKeon, Wayne DeAngelo, and Connie Wagner, which is designed to encourage the proliferation of environmentally-friendly buildings, was approved by the full Assembly. Both bills aim to encourage the incorporation of green and blue roofs into the design of new and existing buildings. Green and Blue Roofs use vegetation or mechanical devices to prevent roof water from draining too quickly, not only to improve storm water management but also to provide cost saving opportunities such as more efficient energy usage for heating and cooling. [1.30.13]

A three-bill package sponsored by New Jersey Assembly Democrats Ruben Ramos, Jr., John McKeon, Wayne DeAngelo, and Connie Wagner, which is designed to encourage the proliferation of environmentally-friendly buildings, was approved by an Assembly panel. The first two bills aim to encourage the incorporation of green and blue roofs into the design of new and existing buildings. Green and Blue Roofs use vegetation or mechanical devices, respectively, to prevent roof water from draining too quickly, not only improve storm water management but also provide cost saving opportunities, such as more efficient energy usage for heating and cooling. "It's time to start making forward-thinking, eco-friendly solutions a priority for today, not a promise for tomorrow," said Ramos (D-Hudson). "Blue and Green roofs are a smart approach that will help save money in the long-term while also protecting our environment." [6.15.12]

ASTM International

ASTM International Committee D08 on Roofing and Waterproofing, through its Subcommittee D08.24 on Sustainability, is developing several standards for sustainable roofing systems. One such standard is ASTM WK26599, Guide for Design of Sustainable, Low-Slope Roofing Systems. “The proposed standard embraces the fact that the primary purpose of the roofing system is to protect the top of the structure over the course of the roof’s design life, and that sustainable considerations such as use of the roof for water collection, vegetation, photovoltaics or use of newer or recycled products deemed environmentally friendly must not sacrifice this key aspect,” says Eric Olson, consulting engineer, Simpson Gumpertz & Heger Inc. [10.18.13]

Standards from ASTM International Committee E60 on Sustainability guide work on vegetative green roofs. ASTM International members began to develop vegetative green roof standards in the early 2000s in Subcommittee E06.71 on Sustainability (now reorganized as Committee E60 on Sustainability) with the creation of the green roof task group. Meadows says that the responsible task group looked to work on a comprehensive document, a “granddaddy” standard that would address the breadth of vegetative green roof considerations. The proposed guide, WK25385, Guide for Vegetative (Green) Roof Systems, now being balloted, has facilitated the task group’s work on related standards that have been approved. The vegetative green roof task group has more standards development activities planned. Currently under way is a proposed standard on selecting waterproofing membranes for green roofs, which will list characteristics, materials and suggested performance requirements. The group will also be looking at possible vegetative green roof standards that address irrigation, fire, wind scour and roofs with steep slopes. Where there are vegetative green roofs, right below the surface there may be an ASTM International standard. [6.12.13]


ASTM Sustainability Committee develops standard for use of expanded shale, clay and slate in vegetative roofing systems. A new ASTM International standard will aid in the selection of lightweight aggregate best suited for use in the design and construction of vegetative roof systems. ASTM E2788, Specification for Use of Expanded Shale, Clay and Slate (ESCS) as a Mineral Component in the Growing Media and Drainage Layer for Vegetative (Green) Roof Systems, was developed by Subcommittee E60.01 on Buildings and Construction, part of ASTM International Committee E60 on Sustainability. Specifiers, blenders and users of lightweight growing media for green roof applications will be the primary users of ASTM E2788. According to Chuck Friedrich, an E60.01 member, ASTM E2788 provides typical gradations, physical and chemical properties of the rotary kiln expanded lightweight aggregates that can be used as a lightweight fill, drainage material or as growing media component for green roofs. “ASTM E2788 can be used to select the size and type of lightweight aggregate best suited for a project,” says Friedrich, of the Carolina Stalite Co. “The selection will be determined by local availability, but the new standard gives a broad scope of the properties that will allow most ESCS products in each region to meet the specification.” [7.16.12]

Forty-six ASTM International standards covering various aspects of building construction are cited in the 2012 International Green Construction Code (IgCC). Published by the International Code Council (ICC), the new model code addresses the construction and remodeling of residential as well as commercial structures. The IgCC is expected to increase cost savings and job growth while enabling safe and sustainable building design and construction. ASTM green construction standards such as E2399 on green roof systems, C1549 for solar reflectance and E2635 on water conservation in buildings are part of the 2012 code. [3.28.12]

The ongoing focus on sustainability in construction has contributed to greater interest in vegetative, or green, roof systems, in which traditional roofing material is replaced or supplemented with vegetation. A proposed new ASTM International standard will address an important aspect of designing this kind of roofing: determining the proper roofing and waterproofing membrane for a particular system. The proposed new standard, ASTM WK29304, Guide for Selection of Roofing/Waterproofing Membranes for Vegetative Roof Systems, is currently being developed by Subcommittee D08.24 on Sustainability, part of ASTM International Committee D08 on Roofing and Waterproofing. [8.24.10] 


The Growing Green Guide: A guide to green roofs, walls and facades in Melbourne and Victoria is now available. The guidelines have been written for Melbourne and Victoria but much of this information has national and international relevance. The Growing Green Guide team has issued an open invitation to others to use the guidelines’ contents to develop additional resources, or even produce a second version through their Creative Commons licensing. This guide is only one of three main outputs developed by the Growing Green Guide project team – a policy options paper and feasibility study and design for four demonstration sites have also been completed. On their website you will find the comprehensive policy options paper for use by government and others in developing policies to encourage green roofs and walls and an opportunities assessment for demonstration green roof and wall sites in each partner council’s municipality. While the publication of the guidelines marks the completion of the Growing Green Guide team’s planned work, this is not the end of the Growing Green Guide project; it is the start of mainstreaming green roofs and walls into our built environment.

EFB (European Federation of Green Roof Associations)

The EFB is an organisation that brings Europe's green roof associations together. The ten associations promote and encourage the uptake of green roofs in their countries to help address issues related to climate change, ecosystem services, green infrastructure and lack of green space in the built environment. The Association also reaches out to non-member countries to facilitate the growth in green roofs and the establishment of an national association. Interested non-member individuals, companies and public bodies can contact our office for advice and help.

The original green roof associations of Austria, Germany and Switzerland established the European Federation in 1997. Since then the following associations have joined: Dutch, Belgian, Scandinavian, Hungarian, Italian, Polish and British associations.

ICC (International Code Council)

The ICC Council provides access to new “California Solar Permitting Guidebook” that makes permit review, installation of solar pv systems in California easier. The State of California Guidebook is available as a free download or in print from the Code Council, and addresses permitting requirements, and assists installers and code officials. The guide focuses on the permit review and approval to install a solar PV system. It highlights solar PV installations on residential and commercial building rooftops, in parking lots and on parking structures, and those mounted on the ground. Each of these has specific installation requirements addressed in the guide. Although the combination of solar and greenroofs together are not yet addressed, they could be in the future. [9.19.12]

ICC announces availability of New Green Code; The International Green Construction Code is the path to safe, sustainable, economical construction. A new model code for constructing and remodeling buildings is expected to make buildings more efficient, reduce waste, and have a positive impact on health, safety and community welfare. The 2012 International Green Construction Code (IgCC) will increase the energy-efficiency of structures, while providing direction and oversight of green design and construction, according to the International Code Council. [3.28.12]

Final hearings for the 2012 International Green Construction Code (IGCC) conducted last month yielded a number of advances for energy efficient and sustainable thermal envelopes, such as the inclusion of a straightforward approach to minimum thermal requirements for roof and wall systems. In addition, the new code extends the minimum thermal requirements to all low-slope roof replacements involving above-deck insulation. The International Codes Council will publish the first edition of the IGCC in the spring of 2012, and it is expected that many state and local governments will quickly adopt the IGCC as the primary benchmark for “green” construction standards and practices.

ICC Evaluation Service, LLC (ICC-ES) has announced that it is ready to serve its current and new clients by certifying their products and materials to the requirements of the International Green Construction Code (IGCC). The Rhode Island Green Buildings Act identifies the IGCC as a standard to determine compliance with requirements that all public agency major facility projects be designed and constructed as green buildings. The state has joined other jurisdictions that have already adopted the IGCC. [10.22.10]

In 2009, the International Code Council (ICC) launched the development of a new International Green Construction Code (IGCC) initiative committed to developing a model code focused on new and existing commercial buildings addressing green building design and performance. The IGCC is applicable to the construction of buildings, structures and systems, including alterations and additions. The IGCC is not a rating system; however, it incorporates project electives to encourage and drive the construction of buildings that exceed the already stringent minimum requirements of the code, much like rating systems do. The ICC has posted the results of the Public Hearing for the International Green Construction Code held in August 2010. To see the public comments submitted by May 14 or the results of the public hearing, visit the ICC's website:

The next version of the IGCC will be issued on November 3, 2010, with code change proposals due on January 3, 2011. Proposals can be submitted any time in that two-month period. This is the last opportunity that the public will have to submit proposals on IGCC until it is open for revisions in three years. The next round of IGCC hearings will take place in Dallas, Texas, in May 2011, where the focus will be on feasibility and enforceability of the code.

New Green Construction Code Unveiled. The International Code Council announced the release of Public Version 1.0 of the International Green Construction Code (IGCC) to regulate construction of new and existing commercial buildings. The IGCC offers a safe and sustainable regulatory framework for the green construction of commercial and high performance buildings. The IGCC aims to significantly reduce energy usage and greenhouse gasses. It addresses site development and land use, including preservation of natural and material resources. Enforcement of the code will improve indoor air quality and support the use of energy-efficient appliances, renewable energy systems, water resource conservation, rainwater collection and distribution systems, and the recovery of used water (graywater). The IGCC initiative was launched in 2009 with Cooperating Sponsors the American Institute of Architects (AIA) and ASTM International. The support of the AIA underscores its long-time leadership in the sustainability movement, including its 2030 Carbon Neutrality challenge, and its emphasis on the critical role of architects and designers in the life cycle of sustainable construction.

IGRA (International Green Roof Association)

Life on roofs - recreation, sports and fun - this is the main theme of the current issue of Green Roof News 1 - 2014 and we’ll be showcasing the manifold usage possibilities with examples from Singapore, Istanbul, Berlin and Copenhagen. Ski slopes, golf courses, swimming pools or playgrounds on roofs – all of these examples follow the tradition of the Swiss-French architectural theorist Le Corbusier by making roof gardens preferred gathering places on buildings. If we change the colour from green to white: There have been many discussions about white roofs to respond to the challenges of climate change and the urban heat island effect. Let us take a look on a scientific study and the results to be prepared for further debates. For the first time you will find a research review of the year 2013 with selected articles from the international pool of publications. Apart from that, we will put a spotlight on the causes for the Riga supermarket roof collapse. And we will present Green Roof projects from different countries and feature some interesting green building events. [4.21.14]


IGRA announces their "Green Roof Leadership Award 2010", the High Line Park in New York City. The New York High Line Park, a new “elevated urban park” which already has set an example. At a height of approx. 10 m it connects whole districts above all the traffic and provides splendid views and at the same time recreational space for adults and children. In fact, the High Line Park is a flat Green Roof (admittedly a very long one) as it has been installed on a waterproofed area without connection to the ground. [11.9.10]  



The University of Haifa has dedicated Israel’s first research center for Green Roofs Ecology, which will focus on research and development of non-irrigated green roofs; improving biological diversity with green roofs; and developing ecological and evolutionary theories. The center has been established thanks to a generous gift from a British expert in the field, and was facilitated by VP for External Relations and Resource Development Amos Gaver. Over recent years, awareness of the “green roofs” gardening method atop building roofs has increased. It is intended to enhance a building’s energy efficiency while minimizing environmental damage. The rooftop vegetation creates better insulation for the building, which lowers air conditioning and/or heating consumption; improves photosynthesis in the city; and of course serves as an urban living space for various animals.

The mission for the Korea Green Roof & Infrastructure Association (KOGRIA) is to foster cooperation among governmental as well as private organizations, research institutes, educational institutions, and green roof companies for the Construction of Urban Green Space for the Future. At first, we came together to discuss the issue on Urban Green Space Project, aiming to change our desolated city filled with grey concrete into lively one with greening. Then, we reached a conclusion; R&D for the advanced green technologies and its distribution are the most realistic as well as idealistic solution. In an effort to find the best ways to proceed with it, we organized “Association for Study on Green Roof,” and released many presentations as well as articles for Roof Greening periodically. Also, we hosted lots of symposiums and seminars, inviting relevant professionals to introduce the needs of roof greening system, the techniques as well as methods, and good examples on it. With our continuous activities, research and studies on Green Roof Project, finally, we officially established Korea Green Roof & Infrastructure Association (KOGRIA) with authorization of Ministry of Environment on Jan, 2003. Since then, KOGRIA has constantly tried to create new urban green spaces based on the outcomes and experiences through our studies. [12.29.12] 

The Green Roof Organisation (GRO)

The team at Groundwork Sheffield and the Green Roof Centre in the UK have been at it again. Following the launch of the GRO Green Roof Code for the UK in February, March brings the Green Roof Guide. The Guide is designed to sit alongside the GRO Code as a more accessible route to the technical information the Code holds. Once again the project was funded by the European Commission Life+ fund and Groundwork Sheffield, with financial support from the Homes and Communities Agency and The Green Roof Guide is designed to enable people to get the answers they need about their green roof project, whatever its size. By simply clicking on the relevant question under each topic most common concerns can be resolved. Any part of the guide can then be saved or printed out as a PDF, and all of the information is free to all users. [3.3.11]

The Green Roof Organisation (GRO) is a UK body facilitated by the National Federation of Roofing Contractors (NFRC) and a partnership of Industry (green roof manufacturers and installers) and Stakeholders, coming together to develop guidance for the specification, design, manufacturing, installation and maintenance of Green Roofs. Due to the manner in which this document was created it can be considered to be the result of professional expert work. The GRO code is intended to be recognised as a code of best practice and as such it should be used to guide behaviour relating to green roof design, specification, installation and maintenance. This code has been developed in partnership with national and European experts, including The Green Roof Centre at the University of Sheffield,, GRO (Green Roof Organisation) members, the Environment Agency and Homes and Communities Agency. Groundwork Sheffield secured funding to create this code of best practice which provides guidelines and references to relevant standards for the requisite quality of green roof design, installation and maintenance of green roofs across the UK.

Innovation Will Drive Costs of Green Roofs and Walls by 28% in 2017. Combining diverse approaches can cut costs to $23/ft2 but building-integrated vegetation (BIV) will still depend on incentives for wider adoption, says Lux Research. Building-integrated vegetation (BIV) – the use of green roofs and green walls to improve air quality, manage storm-water and generate energy savings – is experiencing a burst of innovation to lower costs and hasten payback on investment, according to Lux Research. In the drive to demonstrate economic value, the $6 billion industry has come up with a number of new ways to reduce material, installation and maintenance costs. All told, costs could be cut 28% -- from $38/ ft2 in 2012 to $23/ft2 in 2017, according to a Lux Research analysis. [8.19.14]

Burgeoning Green Roofs and Green Walls Market to be Worth $7.7 Billion in 2017. Green roof installations will rise 70% to 204 million square meters, but costs and lack of validation will limit their rise, says Lux Research. Green roofs and green walls, sought to address environmental issues like air pollution, heat-island effect, and loss of green spaces in cities, will balloon into a $7.7 billion market in 2017, driven by mandates and incentives by cities across the globe. Green roofs will account for $7 billion of the market, presenting a $2 billion opportunity to suppliers of polymeric materials such as geosynthetic fabrics and waterproof membranes. Green walls will swell to a $680 million market, using $200 million worth of materials such as self-supporting polyurethane foam growth media. [10.18.12]
