As a final reminder, those of you wishing to present in London, UK, this September 15-16, 2010 at the World Green Roof Congress, you need to submit your abstracts by this Friday, March 12! Abstracts are invited for submission on a range of topics.
The World Green Roof Congress is hosted and delivered by CIRIA and Livingroofs.org. We were there in 2008 and had a grand time in a wonderful setting with many knowledgeable speakers! The Congress attracted over 300 delegates from around 15 countries and numerous exhibitors. Hopefully you will attend this year, too, and further your greenroofing experience!
Call for Papers
“The World Green Roof Congress in 2010 will showcase green roofs and green walls, and how we can progress their delivery and achieve their mainstream inclusion in buildings. The Congress will also focus on what can be done to fully exploit the multiple benefits of green roofs and adapt to a changing climate.
The Congress committee are looking for papers, presentations and case studies that demonstrate the delivery of green roofs and green walls providing a diverse range of benefits, and the evidence base to demonstrate that they not only look aesthetically pleasing but bring significant socio and economic benefits.
The Congress is keen to have papers and presentations that cover these themes: 1. International green roof case studies; 2. British green roof case studies; 3. Policy and regulations for green roofs; 4. Up on the roof – urban agriculture, amenity and place making; 5. Planting and growing media for green roofs; 6. Biodiversity benefits; 7. Water management benefits; 8. Green roofs and climate change adaptation; 9. Retrofitting green roofs; and 10. Delivery of green roofs.”
The Call for Papers closes on March 12, 2010 - learn all about the submission guidelines, requirements, and process here: World Green Roof Congress.

Despite the global economic slowdown, India is the second fastest growing major economy in the world, and the projected market potential for green building material and technologies is estimated to be $40 billion by the year 2012. India has pressing water needs – the Himalayan icepack is shrinking and is the main water source for more than a billion people in this part of the world. Groundwater resources are greatly diminishing by several centimeters per year and are not being replaced, so sustainable design is extremely important!
Although vegetated roofs are relatively new in the building, construction, and landscaping industry here, many believe they have immense potential for growth in India. One glowing example is the CII – Sohrabji Godrej Green Business Centre (CIIGBC), a division of Confederation of Indian Industry (CII). Located in Hyderabad, the CII is India’s premier developmental institution, offering advisory services to the industry on environmental aspects and working in the areas of Green Buildings, Energy Efficiency, Water Management, Environment Management, Renewable Energy, Green Business Incubation and Climate Change activities. The LEED Platinum for New Construction (NC) v 2.0 certified CII – Godrej GBC building is also home to India’s first and largest built greenroof (2003), at about 11,000 sf. Layed out in a circular fan-like fashion, solar panels add to the uniqueness of the design, easily read from above as seen in this Google shot below.
Vegetated roofs cover 55-60% of the building’s roofs - the remaining portion of the roof is covered by a solar photo voltaic installation with a 24 KW capacity. The 100 to 120 units of power generated per day is fed into the grid meeting 20% of the total energy cost of the building. CII maintains a “Score Card” of green statistics within India. These are their current figures, as of March 6, 2010:
68 certified green buildings
352 million sq ft Green building footprint
500 registered green building projects
1050 energy audits carried out
Rs.2000 Million annual recurring energy saving realized
32 Water Audits conducted
8.0 Million Cu.m annual water saving
11 Green SMEs funded
Rs.95 Crores green investment facilitated
418 industrial units subscribe to the CII – Code
World traveller and our Student Editor, Christine Thüring visited the CIIGBC last year and wrote about her experiences in the March 2009 Guest Feature ”Green Buildings in India.” In 2000, the Indian Green Building Council(IGBC) – part of CII-Godrej Green Business Centre – and created its own LEED® Green Building Standard by fine-tuning the ratings to reflect Indian conditions and priorities (e.g. more points for water conservation). Point in fact: rain harvesting is mandated by Indian law.
The CIIGBC achieved 56 LEED points, and a key aspect of the CIIGBC is its zero discharge of water, aided by the greenroofs, among other features. All wastewater and runoff generated by the building is recycled by “root zone treatment” where specially selected plants purify and filter the water that irrigates them (top photo above ). Water leaving the “root zone treatment” is directed to one of three ponds, thereafter to be used for domestic purposes. The building achieves a 35% reduction of municipally supplied potable water, in part through the use of low-flush toilets and waterless urinals (bottom photo above).
Although roof gardens in various forms have been around for decades, I couldn’t find many examples of built or proposed greenroofs (if you know of others, please let us know!). One important one is presently under construction - the new International and Domestic Terminal at the Chennai International Airport has many environmentally friendly features. The New York team led by Frederic Schwartz Architects and Gensler with Hargreaves Associates and India-based Creative Group was unanimously selected by the Indian Government to design the Kamraj Domestic Terminal Building. Its dramatic sweeping roof lines collect rainwater and fold downward into two lush, one-acre gardens. The garden walls capture water during the wet season into a series cisterns and runnels where it is stored for reuse as irrigation during the dry season. Directly connected to the terminal is a new parking garage with a sculptural folding greenroof that welcomes travelers with a “green gateway” to the terminal. India’s greenest airport is slated for completion sometime in late 2010.
Several conferences this year will address sustainable design and the potential for living roofs in India. ROOF INDIA 2010, now in its ninth year, is Asia’s largest roofing and allied technologies event. This year, greenroofing will be included as a segment and in fact, it’s endorsed by the NRCA and IGRA, among others. Visitors receive free entry with registration and Visitor Badge. Companies providing technologies, products, services, consultancy & solutions for roof landscaping will be exhibiting at the event. ROOF INDIA 2010 will be held April 23 – 25, 2010 at the Chennai Trade Centre, Chennai, India.
Karen writes “By coordinating expertise from North America, Europe, Latin America, Africa and Asia on green roofs, water, buildings and climate, we intend to bridge the East and West. Our aim is to have all participants sign a letter of commitment to establish green roofs as a priority along with a timeline for implementing green roof technology on a wide scale as India and Western China plan their new cities and regional development. ”
The Confederation of Indian Industry and the Indian Green Building Council (IGBC) – part of CII-Godrej Green Business Centre - will be presenting their eighth annual Green Building Congress 2010, India’s flagship event on green buildings. Objectives include creating awareness of green building concepts, the latest global trends, new products and technologies, providing a platform for networking, facilitating new business opportunities and enabling market transformation of green products and equipment. The Green Building Congress 2010 will be held on October 6 – 9, 2010 at the Chennai Trade Centre.
The CII – Sohrabji Godrej Green Business Centre is located at Survey # 64, Kothaguda Post, R R District, Hyderabad – 500084, India; Tel: +91 40 2311 2971 – 73; Fax: +91 40 2311 2837.
Known as “The Rose City” for its famous yearly Rose Festival and The Grand Floral Parade in early June, Portland Oregon could also be easily known as “The Eco City” or perhaps even “The Green City” because of their ongoing commitment to preserving their magnificent waterways and forests while promoting sustainable design and development through progressive urban policies and public outreach. The last time we were there was for the 2nd Annual Greening Rooftops for Sustainable Communities Conference, Awards & Trade Show in 2004. And we spent some time here in late 2003 when I was compiling info for my Sky Gardens ~ Travels in Landscape Architecture column on the area. Such a beautiful city!
On March 12-13, the lovely City of Portland will be sponsor and host to their annual free Ecoroof Portland. What an amazing city for supporting greenroofs – or ecoroofs, as they refer to them here. Currently with about 200 projects within the city, ecoroofs cover about 10 acres, leading the U.S. in total area greened after Chicago. And they were one of the first, if not the first, municipality in the nation to offer incentives. As part of the Grey to Green Initiative, the City of Portland is offering an incentive of up to $5 per square foot for ecoroofs towards a target of 43 additional acres by 2013. In the past year, the Bureau of Environmental Services (BES) awarded the incentive to 50 projects for a total of over 4 acres. Read more in Industry Support and the City’s Incentive Project Page for more information. You can visit ecoroofs and other sustainable stormwater projects in Portland with these self-guided tours, and the City maintains an Ecoroof Blog, which is very informative, too!
The premier champion there of stormwater mitigation, and ecoroofs in particular, is Tom Liptan, ASLA. I’ve known Tom for over 12 years, when I first contacted him about greenroofs back when I was a landscape architecture student at UGA a had “discovered” them myself. Gracious, kind, and accommodating, he nurtured and fueled my passion for this earth-friendly sustainable technology. And Tom has always put his money where his mouth is – he installed one of the first ecoroofs in Portland atop his garage in 1996. The now famous Liptan Garage Greenroof served as early a demonstration project and testing grounds for a variety of factors – read more in the profile.
Designed to inform a varied audience of professionals and homeowners, the lineup of speakers will educate and inspire you to consider a greenroof on your next project. A Vendor Fair with over 60 professionals and organizations will be on-hand both days to share their ecoroof experience, products, and services. Featured speakers include Dr. David J. Sailor, Ed Snodgrass, and me! Dr. Sailor is a full professor at the Mechanical and Materials Engineering faculty at Portland State University, Member Faculty of the Oregon Built Environment & Sustainable Technologies Center (Oregon BEST), and directs Portland State University’s Green Building Research Laboratory. Ed Snodgrass is co-owner of Emory Knoll Farms/Green Roof Plants, a fifth generation farmer and nurseryman specializing in plants and horticultural consulting for greenroofs. An accomplished speaker and writer (“Green Roof Plants: A Resource and Planting Guide”), he’s also our Plant Editor who writes his occasional column “Ask Ed“ – read my “From Llamas to Greenroofs: An Interview with Ed Snodgrass.” See full profiles here and a complete list of all the speakers and Agenda here.
See Ed on Friday at 12:00 pm at the Welcome and Keynote Address where Environmental Services Director Dean Marriott will welcome attendees and introduce Ed as the Keynote Speaker. His presentation will focus on the role of ecoroofs in sustainable cities. On Saturday at noon, Commissioner Dan Saltzman will welcome attendees and introduce me – I will be presenting “Hot Trends in Greenroof Design,” a compilation of my favorite international projects from our Top 10 Lists from the past with a look at some of the new, innovative, leading vanguard and projects for 2010. On Saturday at 4:00 pm Ed will be part of a panel where you can get some help getting started on your own ecoroof project – “The Ecoroof Doctors are IN,” along with Tom Liptan, David Elkin, and Alice Meyers from BES, and Patrick Carey of hadj design, a Green Roofs for Healthy Cities trainer, and our Architecture Editor. Patrick writes an occasional architectural column entitled “A View from the Sky Trenches,” where he selects and discusses pertinent greenroof industry topics.
Don’t miss Ecoroof Portland! It will run on Friday and Saturday, March 12 & 13, 2010 at the Leftbank Annex, located at 101 N. Weidler St in downtown Portland. It’s very close to the Rose Quarter – you can find directions by clicking the following link. Learn all about Ecoroof Portland 2010 at the City’s BES website.
If you can attend, please stop by and say hello! Happy greening,
Formerly the Gimbel’s Department store, the Heinz 57 Center in Pittsburgh, PA, is a wonderful example of urban renewal. Closed and neglected for about 14 years starting in the late eighties, the now restored building has been put to reuse not only in a sustainable, but beautiful way. In 1998 architects Burt Hill Kozar Rittlemann Associates (now Burt Hill) were brought on board to redesign the historical but ailing structure.
Along with McKnight Development Partners, the architects incorporated a dramatic 50′ diameter octagonal atrium which runs from the roof down through seven floors. Suddenly flooded with natural light, the Heinz Corporation was enticed to occupy the top seven floors for their North American headquarters. Yet curiously, environmental concerns were not driving factors for the greenroof then; aesthetics, however, definitely were.
Although the building itself was surrounded by a spectacular city panorama featuring a soaring cathedral amidst an eclectic mixture of towering skyscrapers, the views from the lovely floor-to-ceiling windows of the fourteenth-floor penthouse suite were less than exciting or acceptable: a hot black rubber roof under an equally unappealing nine-foot-high brick parapet wall greeted Heinz occupants. So the architects decided a pleasing landscape atop the roof would do the trick.
Completed in the fall of 2001, the Heinz 57 Center was the first vegetated roof in downtown Pittsburgh, where executives enjoy sweeping meadow vistas wrapping their offices and blanketing the thirty-foot-wide terrace. Four informal seating areas constructed with high-density recycled plastic lumber decking and concrete paving blocks provide informal gathering spots; by all accounts the colorful corporate roof garden is a hit!
Last year I was interviewed by Carmen J. Lee who was writing for h – The Magazine of the Heinz Endowments, reporting how “Pittsburgh roofs are the new fertile turf for environ-mentally sustainable construction projects that aim to dig in and blossom” in her article “Top Soil” (pages 24-31). The Heinz 57 building was, of course, one of the sites featured and you’ll see I was quoted with more of an inspirational bent rather than specific to the project. Carmen also profiled the local environmental group, 3 Rivers Wet Weather, which is responsible for utilizing $525,000 in federal funding plus a $125,000 Heinz Endowments grant to sponsor a 2005 project to create more greenroofs here.
In a city with an over-burdened sewer system with frequent overflows, Pittsburgh officials and researchers cite the greenroof project often as a fine example of sustainable redevelopment. Situated within a pedestrian-friendly mixed-use business district with shops, restaurants and businesses, the Heinz 57 Center is worker friendly as well as eco-friendly, providing their 800+ employees with a variety of alternate forms of transportation. Although Heinz executives may not have initially specified the extensive greenroof for ecological reasons, they certainly appreciate the many noticeable environmental benefits, such as the cooling respite from the city canyon and the reduction of stormwater runoff; it’s estimated that the roof retains 55% of yearly rainfall.
Charlie Miller, P.E., and his company Roofscapes, Inc. have been responsible for a large number of award-winning greenroof projects, including this one. His private and public portfolio runs the gamut from municipal to corporate, institutional to retail, and even includes some single-family residences. Charlie won the 2005 Green Roof Award of Excellence with the Heinz 57 Center/Gimbels Building Restoration in the Extensive Industrial/Commercial category, and we featured it in the 2009 Greenroofs of the World Calendar™ by Greenroofs.com for the month of March:
Over 18,000 plants were selected by Roofscapes, who used their Type III: Savannah Roofmeadow® system. Landscape architect Steven L. Cantor researched this project in depth, and you can read his extensive case study including complete plant lists on pages 139-142 in the excellent book “Green Roofs in Sustainable Landscape Design,” 2008, available for purchase on Amazon.com.
Steven relates how the Heinz 57 Center plant selection encompassed “32 xeric species from nineteen plant genera, including six North American natives; approximately one-third of the plants are sedums, and the balance is a range of herbs, meadow grasses, and meadow perennials that provide differences in plant height, texture, and bloom color.”
It’s hard to believe, but the roof is not irrigated and has flourished with minimal maintenance, which includes twice yearly weeding and an annual light application of fertilizer.
Pittsburgh has really come along way from its gritty industrial Steel Town roots, emerging as a leader in green building. According to the Green Building Alliance, as of July, 2009 the City of Pittsburgh is home to 39 LEED-certified buildings, ranked eighth in the United States for overall number of projects.
About two dozen more eco-friendly greenroofs are found within metro Pittsburgh; read the May 19, 2009 article ”More city buildings cultivate savings by covering roofs with plants” by Sally Kalson of the Pittsburgh Post-Gazette to learn about additional living roofs in the area.
We only have a handful of those references listed, so remember to send us case studies of these other projects so we may share it with all of you in the greenroof community in The Greenroof & Greenwall Projects Database.
Kudos to the designers, corporate leaders and all the stakeholders of this inspiring city-core Heinz 57 Center renovation for their foresight - environmental, aesthetic, or otherwise - to successfully integrate a greenroof into the overall design for the benefit of the building’s occupants!
What’s GPW? I’m starting a new blog feature here on Sky Gardens ~ where cool green meets lofty blue, to go along with Greenroofs.com’s “Greenroof/Greenwall Project of the Week” – or GPW. I’ll note back stories for each selected project and include updates, new photos, etc., and share why I feel this is a noteworthy and interesting case study.
Also known as Millennium Water, the Vancouver 2010 Olympic and Paralympic Village at Southeast False Creek (SEFC) will eventually become home to 16,000 residents and commercial users after the Winter Games with 250 affordable housing units in its first phase, a 45,000 square foot community center, three child care centers, an elementary school, community garden, public plaza, and much more. The 32 hectare (80 acres) SEFC community is a former industrial site on the shores of False Creek near downtown Vancouver, B.C. More than half of the land is owned by the City, while the remainder is owned privately.
Millennium Development Corporation developed the $1-billion-plus waterfront property, and the master plan for the sustainable community provided a unique opportunity to develop an urban center for residential, commercial and public use. The City of Vancouver is to be recognized as a governmental trailblazer and recommended for dictating 50% greenroof coverage for the entire area!
Dubbed “The most sustainable neighbourhood on Earth,” on Tuesday the Olympic Village in Vancouver’s Southeast False Creek was awarded LEED® Platinum ND certification by the U.S. Green Building Council for a variety of factors, including its proximity to the downtown core, mix of uses, affordable housing, green buildings and habitat restoration. And the Canadian Green Building Council announced the Gold certification of all residential buildings on the Millennium Water site.
”This should be a source of pride for residents and an example to the rest of the world.” ~ Vancouver Mayor Gregor Robertson
Back in 2007 our Design Editor, Haven Kiers, and I included the Vancouver 2010 Olympic Village (Millennium Water) in our inaugural Top 10 List of Hot Trends in Greenroof Design, as a current example of trendsetting sustainability efforts on a city scale. We showed it as an example of the #1 category on our 2007 list for ”Visionary Proposed Projects” - see the PowerPoint here. NATIONAL, Millennium Development’s public relations firm, provided these images of the various models for our presentation and the profile in The Greenroof & Greenwall Projects Database.
Last October at the inaugural 2009 CitiesAlive! World Green Roof Infrastructure Congress in Toronto, I attended Dr. Karen Liu of Xero Flor Canada’s presentation, “Special Green Roof Projects in B.C.” where she shared the company’s design and engineering experiences for their part in the Olympic Village’s extensive greenroofs. In the Master Planting Plan (see below) the landscape architect, Durante Kreuk, had created vegetated silhouettes of Olympic sports figures atop the buildings, so to achieve this, a combination of various planted Sedum plugs, annuals and lightweight red lava rock were used. Shallow aluminum edging helps define the different color and plant zones:
To update the profile, I relied on the excellent case study by The Challenge Series entitled “Millennium Water: The Southeast False Creek Olympic Village - Vancouver, Canada.” The story of the development is told in a seven-chapter book that documents the decisions and challenges involved in creating such a showcase and world-class example of green development strategies. You can access the entire book online above, order printed copies, or subscribe to their newsletter. Referring to the recent LEED awards, Roger Bayley of The Challenge Series stated:
“This esteemed certification reflects the dedication to sustainable community development that is found throughout the Millennium Water: SEFC community, and is a truly commendable achievement for all those who were a part of the planning, design and construction process.” ~ Roger Bayley
Of course Vanouver has many beautiful greenroofs and greenwalls, and just one of numerous other great buildings with a spectacular greenroof not to be missed is the Vancouver Convention Centre Expansion Project, which we’ve previously highlighted as our “Greenroof Project of the Week.”
Completed just last November, 2009, it will be interesting to see how the Olympic Village rooftop vegetation fills in and greens up after a few seasons, and we certainly look forward to visiting this beautiful city with many eco-friendly projects in November, 2010.
Kudos to the people of Vancouver, B.C. and all involved in the many years of making the Vancouver 2010 Olympic Village at Southeast False Creek a wonderful, welcoming place for the athletes, officials, and visitors, and for designing Millennium Water as a future sustainable home to Vancouverites!
The Greenroof & Greenwall Projects Database has been up and open to the world since 2004, evolving from the “International and North American Case Studies” portion of my initial 1999 independent research study “Greenroof Technology: A Viable Roofing Alternative” that was the basis for Greenroofs.com. The initial 30 or so profiles have grown to over a thousand, and we feel sharing these is an important learning experience for us all.
Our Project of the Week feature started in March, 2006 when we selected the profile of Phillips Eco-Enterprise Center (PEEC), above, submitted by Peter MacDonagh of The Kestrel Design Group. The idea stemmed from the notion that a weekly highlight showcasing very different living roofs would stimulate interest in both the industry at large and our Projects Database – which it has! Since then we’ve shown about 190 vegetated roofs and in 2008 we displayed our first Greenwall Project of the Week, Anthropologies, below, submitted by George Irwin of Green Living Technologies.
I often get asked, how do I pick each greenroof/wall case study out of and over so many other profiles? The answer is actually very simple – at its core, I’m basically choosing completed profiles. That means all the fields are completed, there is a lot of descriptive text, and all 11 of the photos/graphics are there. The emotionally and physically attractive, sexy part about living architecture is the living part – the planting design - and people want to see photos!
After the aesthetics of the profile itself, I try and alternate U.S. and international projects, although it doesn’t always come out that way. My goal is to show different types (extensive, intensive) and various applications, too (research, municipal, multi/single-family residential, commercial, educational) along with system types (conventional built-in place, modular, custom).
So if you’d like your company or organization’s project highlighted, check to see if we at least have an initial case study up, if not, send one in either by filling out the easy online form here, or by sending us an email to: projects@greenroofs.com. If we do have your project listed, review it and send us any edits or additions along with updated graphics and/or photos (each profile can hold up to 11).
When possible, I’ll highlight a project that has something going on that week or month, for example I like to select profiles whose city is having a conference at the moment, or as in the case of this week’s project, a Green Building Tour this Sunday:
Our current Greenroof Project of the Week features the Sweetwater Creek State Park Visitors’ Center and Museum in Lithia Springs, GA. Set within a 2,500-acre conservation area, this beautiful LEED™ Platinum certified building was the first to achieve this rating in the southeastern United States. (Click on the project title to see who was involved in this very green building.) And if you’re in the area, you can join a Green Building Tour of the Sweetwater Creek State Park Visitors’ Center and Museum this upcoming Sunday, February 14, 2010 from 2 PM to 3:30 PM and learn about sustainability, green buildings and what makes this one so special for just $5 plus $5 parking; for more info call: 770-732-5871.
The Greenroof/Greenwall Project of the Week feature on Greenroofs.com is a great way to have readers – researchers, students, media, and potential clients - see what’s been done, where, how, and by whom. You’ll always find a new one on the Home Page every Sunday afternoon – just click on either the photo itself or the “Where in the Greenroof World?” hyperlink below to learn all about each unique greenroof or greenwall.
As we continue to ring in 2010 we hope you enjoyed warm holidays with family and friends and celebrated the New Year with renewed hope for the future. Can you believe we’ve entered a new decade? Shall we call it 2K10, Twenty Ten, or just good old fashioned 2,010? In any case, we’re finally out of the 0’s, now we’re into the 10’s.
Our world economy has been through a lot in the past few years, yet with a promising light hovering just over the horizon. Although development overall has declined, there is continued desire for green buildings from both the public and private sector, and in general our greenroof & greenwall industry has weathered quite nicely. Many of us are taking time to reflect on this passage of time and make New Year’s resolutions (another topic altogether!), and I was thinking of how far we have come since the German experience entered our architectural radar and into our collective consciousness in the 1990’s. Literally thousands of vegetated roofs and walls have been constructed since then in every continent except for Antarctica, with ever growing support from forward thinking multidisciplinary professionals: designers, government officials, organizations, companies, universities, students and other advocates looking to make Earth a little more sustainable.
Sadly, one of those special, innovative people passed away last November 27, the indomitable architect Malcolm Wells. Regarded as “the father of modern earth-sheltered architecture,” he was a staunch advocate of living architecture, known for his way ahead-of-the-times underground earth designs with living roofs starting in the 1960’s, see just one example below. He leaves a legacy of what he referred to as gentle architecture, design that would, in his own words, “leave the land no worse than you found it.”
The visionary Malcolm Wells' design for an eco-gas station, from MalcolmWells.com.
Many inspirational people and organizations have contributed to our current market, and I want to highlight just a few success stories from the past year, personal and global. So in my review, here are my favorite 2009 Top 10 Milestones and Accomplishments for both Greenroofs.com as a company and our international community as a whole:
10) In 2009 Greenroofs.com celebrated 10 years of being in business! We’ve seen a lot of progress and change for the good here as well as across the greenroof world. The fledgling Greenroofs.com – “exploring the ecology of organic greenroof architecture” started out as 60+ pages in 1999 as the result of an independent research study I did at the University of Georgia.
By 2003 we changed our format and grew into Greenroofs.com – “the international greenroof industry’s resource and online information portal,” and contained 600+ pages at the end of 2009 (not counting the hundreds of .php pages from The Greenroof Directory or The Greenroof Projects Database). At present, each month Greenroofs.com receives more than 160,000 unique visits and about 400,000 page views, and we’ve also expanded our presence in social marketing, too, so now you can stay connected with us on: Twitter, Facebook, LinkedIn, eNewsletter (our monthly eNewsletter consists of 10,000 opt-in subscribers) & YouTube, as well as our Blog.
9) The proliferation of living architecture is greatly spreading and permeating into the areas of design, policy, research and education through numerousworld conferences, congresses, expos, trainings, tours, and other events. For example, the World Green Infrastructure Network (WGIN) – formerly the World Green Roof Infrastructure Network (WGRIN) - held its first CitiesAlive! World Green Roof Congress in Toronto, Canada, with the second scheduled for Mexico City this October, 2010. The International Green Roof Association (IGRA) hosted the 2nd International Green Roof Congress 2009 in Nürtingen, Germany and the 3rd annual Green Roofs Australia Conference 2009 was held at the University of Melbourne. Longevity was evident with the 7th National FBB Green Roof Conference in Ditzingen, Germany and the 7th annual Green Roofs for Healthy Cities (GRHC) Greening Rooftops for Sustainable Communities Conference, Awards, and Trade Show in Atlanta, Georgia. By the way, look for the 8th annual GRHC conference to occur in Vancouver, B.C. on November 30 – December 2, 2010, rebranded as ”Cities Alive.” Look for many new 2010 events throughout the U.S., Canada, Mexico, Germany, China, Singapore, India and more under Upcoming Events, where you can also access Past Events.
7)Green walls are firmly becoming entrenched in sustainable design,evidenced by high media attention, as much for their green properties as for their edible gardening possibilities. We’ve had tons of news articles posted in NewsLinks, our huge database of global articles, concerning living walls and green façades! In fact, they were listed as #31 in TIME’s 50 Best Inventions of 2009 and Triple Pundit recently proposed: ”Gardens Grow Up: Are Vertical Landscapes the New Green Roofs?“ - both featuring the works of Patrick Blanc. In our business you’d have to be living under a rock not to know who the renowned French botanist is; his often fantastical “murs végétalisés” designs stretch the limits of horticulture and design. Since 1994, he has created over 140 public vertical gardens as well as many private installations, including his most famous, the Quai Branly Museum in Paris, shown below. Read more about green walls from Treehugger, Daily Telegraph, Daily Commercial News, The New York Times, Times Online and CNN.com, just to name a few.
In 2009 Green Roofs for Healthy Cities, the North American professional association, established greenwall research projects at the British Columbia Institute of Technology and the University of Maryland, and GRHC has included an award category for Green Wall Excellence in Design for a couple of years now. In 2008 Greenroofs.com added our 8th Contributing Editor, George Irwin - aptly titled The Green Wall Editor - to cover this growing vertical gardening field, and new for 2010 we have altered the title of our Greenroof Projects Database to reflect the inclusion of these: The Greenroof & Greenwall Projects Database.
6)Investing in green building and infrastructure makes good economic sense by integrating green building policies into wider economic development goals, and creates a new job market. The American Recovery and Reinvestment Act of 2009 (ARRA) has prompted a gigantic increase in federal green spending, providing new money to all levels of government, aimed at stimulating the economy, promoting job growth, and lowering energy costs, providing an unprecedented opportunity for advancing green building and sustainability efforts in the U.S. And last December, the American Institute of Architects (AIA) reported at least 138 U.S. cities with populations over 50,000 people have green building programs in place (compared to only 92 in 2007). Referring to the economic recession, the AIA said “The downturn has had a devastating effect on construction generally, but sustainable building design continues to maintain and improve its market share.” Read their 2009 in depth study “Green Building Policy in a Changing Economic Environment” to learn more.
American Institute of Architects 2009 Study of Green Building Programs by Cities
U.S. economic stimulus efforts encompass green energy and construction, including greenroofs along with other forms of green building, and just one such example of Recovery Act funds benefit Washington D.C., where the Washington Business Journal says “Nearly $4 million would go toward building more than 100,000 sf of green roofs on city buildings, including libraries, firehouses and a demonstration project atop the parking garage deck at University of the District of Columbia. The stimulus funds would also expand the city’s green roof rebate program to allow residents and small businesses to afford another 20,000 sf of private green roof space.”
And importantly, many green building programs are also creating “green collar” jobs. In late 2009, the U.S. Green Building Council (USGBC) and Booz Allen Hamilton conducted a study and stated “Green building will support 7.9 million U.S. jobs and pump $554 billion into the American economy – including $396 billion in wages – over the next four years (2009-2013). The study also determined that green construction spending currently supports more than 2 million American jobs and generates more than $100 billion in gross domestic product and wages…The full report can be downloaded at www.usgbc.org/greeneconomy, where one can also find other research, resources, tools and information about green building and its role in the economic recoveries of professionals, businesses and the nation.” According to an analysis by American Rivers and the Alliance for Water Efficiency, the Natural Resources Defense Council reports that a $10 billion nationwide initiative to install greenroofs alone would result in almost 200,000 jobs – the Senate is expected to consider its own version of the bill in early 2010.
5)Green Roofs for Healthy Cities launched the Green Roof Professional (GRP) accreditation for North America. The GRP is a measure of knowledge of established best practices and although a voluntary program, with the designation professionals can distinguish themselves in the marketplace. This association milestone was at least four years in the making! Currently with more than 250 GRP’s in 2009, GRHC hopes to add more professionals in 2010. Check their website for future testing dates, and consider attending one of their Green Roof Boot Camps to refresh and get you ready. See my interview with Jeff Bruce, president of Jeffrey L. Bruce & Company, Chair of GRHC and the GRHC Training and Accreditation Committee, which developed the Green Roof Professional program, to learn why the organization felt this accreditation was needed, how it evolved, and where it’s heading. For more info on the GRP, see “A Video Introduction to the GRP Program” from Green Roofs for Healthy Cities.
4)Within the U.S. industry, major contributions were made in the area to develop best practice wind and fire standards for greenroof design. Since 2007, leaders from various organizations have been working hard on prescriptive standards, and in 2009 standards were inserted into the International Building Code from members of GRHC and Single Ply Roofing Industry (SPRI). Read “Green Roof Wind & Fire Design Guidelines: After Three Years, Half the Battle is Won,” written by one of our Contributing Editors, Kelly Luckett, The Green Roof Guy, to learn about this winding road’s development of RP-14 and VF-1. And stay tuned for updates with his column here on Greenroofs.com.

3) The global Greenroof & Greenwall Projects Database surpassed the 1,000 mark in December! So where are all these greenroofs and greenwalls anyway? Let’s continue to work together to grow, update, and share valuable case studies for our communal benefit, for free. Even in today’s openly transparent society (think Google Earth), some people worry about confidentiality issues, and we only post information that is submitted to us by owners/project principals or that which is openly available through various media channels, and we always list owners as “private” when requested. The Greenroof & Greenwall Projects Database is now searchable by 24 fields, including specifically for green walls. After our Home Page, the Projects Database is the next visited page on Greenroofs.com – make sure your projects and valuable experiences are included here.
2) My albeitly biased personal favorite, Greenroofs.com inaugurated our first episode of the Sky Gardens ~ Greenroofs of the World™ WebTV series. Premiering at Boston GreenFest in September, our new venture followed on the GreenroofsTV channel on YouTube, and next on our own greenroofs.tv, where you can now see it in its entirety at just under 37 minutes. By the way, you can also view our video offshoot, ”Greenroofs 101 from Greenroofs.com” (4:50) in Greenroofs 101 or directly below, which is a great way to introduce the concept to newcomers. Coming soon is episode 2, highlighting the gorgeous Cook+Fox Architects corporate offices in Manhattan, NY. Our third episode is in the works, and more are being scheduled, so stay tuned!
1) 2009 saw some serious support for greenroofs, championed by professional organizations and governmental bodies alike. Global industry support has grown over the years, and many advocates continue to actively promote them worldwide. For example, the City of Chicago, certainly the U.S. leader in greenroofs, now has over 7 million square feet of vegetated roofs completed or under development. New support in 2009 includes:
North America: In addition to offering eco-incentives for greenroofs, currently Toronto has the most progressive policy in North America – last May Toronto became the first city here to adopt a bylaw to require and govern the construction of greenroofs. The new bylaw will be required on all new development above 2,000 m² (about 21,530 sf) of gross floor area and have a graduated coverage requirement ranging from 20-60%. Working with a program budget of $800,000/year, owners of industrial and commercial buildings can apply for grants worth up to $100,000 (Canadian) to build a greenroof. Mayor David Miller predicts the rules and incentives will create 50 to 60 green-roofed buildings per year, in addition to their current 135 vegetated roofs. Green Roofs for Healthy Cities supported the by-law against pressure from developers opposed to the policy. See more details under Industry Support and at the City of Toronto website.
Here in the U.S., in late 2009 ASLA, the American Society of Landscape Architects, worked with Congress to include the Green Act into the House-passed climate change legislation. The Act would require the Dept. of Housing and Urban Development (HUD) to employ greenroofs, tree canopy coverage, and other site planning techniques to help reduce heating and cooling costs in certain HUD facilities. Still pending before the Senate Finance Committee, last January Senator Maria Cantwell (WA) introduced the Clean Energy Stimulus and Investment Assurance Act of 2009 (S.320), legislation geared toward creating high-wage green-collar jobs and revitalizing the economy through clean energy investments. ASLA worked with Senator Cantwell’s office to ensure that a section of the bill was dedicated to green roof tax incentives, and GRHC provided technical support. Under section 506 of the bill, residential and commercial property owners will receive a 30% tax credit for qualified greenroof expenditures.
As you may recall, Congress enacted Section 438 of the Energy Independence and Security Act of 2007 (EISA) to require federal agencies to reduce stormwater runoff from federal development projects to protect water resources and in October of 2009, President Obama signed Executive Order 13514 on “Federal Leadership in Environmental, Energy, and Economic Performance” calling upon all federal agencies to lead by example and address a wide range of environmental issues, including stormwater runoff. Federal agencies can comply with Section 438 by using a variety of green infrastructure / low impact development techniques including living roofs. Prepared by the U.S. Environmental Protection Agency in coordination with other federal agencies, the “Technical Guidance on Implementing the Stormwater Runoff Requirements for Federal Projects under Section 438 of the Energy Independence and Security Act” PDF is highly detailed and instructive.
State and municipal governments also provided policy support: Former Virginia Governor Timothy M. Kaine signed three bills promoting incentives in 2009: HB 1975 and SB 1058 authorize localities to grant regulatory flexibility and incentives to promote the construction of vegetative roofs on private homes and businesses. The incentives or regulatory flexibility could include a reduction in permit fees, a streamlined process for the approval of building permits, or a reduction in any gross receipts tax on greenroof contractors as defined by the local ordinance. The third bill, HB 1828, allows water authorities to offer rate incentives for vegetative roof construction, based on the percentage of stormwater runoff reduction. In late fall, the Ohio Environmental Protection Agency (OEPA), Metropolitan Sewer District of Greater Cincinnati (MSDGC), and the Office of Environmental Quality created a Green Roof Loan Program utilizing money from the Water Pollution Control Loan Fund. OEPA has made $5,000,000 available for linked deposit, below market rate loans to install green vegetative roofs within the service area of MSDGC on residential, commercial and/or industrial buildings.
Already a city offering several greenroof incentives, in October Portland’s city commission approved a Climate Action Plan which calls for a 40% reduction in carbon emissions by 2030 and an 80% reduction by 2050. According to the Portland Business Journal, “The Plan calls for the city and county to take 93 actions over the next three years. City bureaus must immediately begin implementing 15 of the new climate-related initiatives, such as establishing a tax credit for businesses that install ecoroofs and solar panels together.” And last month, the Milwaukee Metropolitan Sewerage District invited governments, organizations, school districts, and businesses within the 28 communities it serves to participate in their 2010 Regional Green Roof Initiative Program. Among other prerequisites, proposed projects must minimize impervious roof area and maximize the reduction in the rate and/or volume of stormwater runoff.
The World:Singapore is targeting 50 hectares of skyrise greenery by 2030 and its Urban Redevelopment Authority launched the LUSH Programme (Landscaping for Urban Spaces and High-Rises) in April of 2009. Offering financial and planning incentives to developers to provide greenery at the upper levels of high rise buildings, their goal is to make 80% of all buildings in Singapore green by 2030. Quezon City, Phillipines has a new law requiring private and government-owned buildings to green part of their rooftops. New commercial/residential buildings, under the Green Roof Ordinance (Ordinance 1940) signed into law by Mayor Feliciano R. Belmonte, Jr. last September, should allocate at least 30% of their roof area for plants and trees. In Australia, the Queensland Government signed a “Memorandum Of Understanding” with the Singapore National Parks Board late last year to trial vertical gardens and greenroofs in various cities in an effort to benefit from Singapore’s experience with skyrise greenery.
Dubai Municipality launched a greenroof initiative in line with a Dubai law on green building specifications. The Municipality’s strategic goal is to raise per capita green area to 23.4 square meters by the end of 2011, with the green building project coming under the directives of His Highness Sheikh Mohammed Bin Rashid Al Maktoum, United Arab Emirate Vice President and Prime Minister and Ruler of Dubai. A public awareness campaign for greenroofs was announced last month, committed to the “development of laws and regulations to keep pace with international standards in the field of sustainable development by planting green roofs and facades in the Emirate of Dubai.” Traveling display models and educational publications will circulate residential neighborhoods and shopping centers and markets for a 12-month period. Read more on the Dubai Municipality Portal. One spectacular greening project currently on the boards in Dubai is the self-sustained system “Food City” below, designed by Green Concepts Landscape Architects (GCLA):

So here we are at the start of a whole new year – we hope you’re excited and optimistic about it, just as we are! Whatever 2009 offered you, we hope you embraced new friends and opportunities and experienced great personal and professional growth, and we thank you for your readership. What’s in store for our new decade? We’ll see, but as the green building industry continues with positive signs of sustained growth, let’s also continue to collaborate and create a more sustainable world with eco-architecture embracing greenroofs and greenwalls as part of the overall green living architecture strategy.

Here’s a gentle toast to continued health, love, and prosperity for you, your families, and all of our greenroof associates in 2010!
Did you see that the Auckland-based Natural Habitats Landscapes recently designed and installed NZ’s first commercial interior greenwall? Sexy, too, imagine getting your hair done with living, clinging, luscious plants breathing down your neck…
Very cool reality coming from the land of so many fantastical landscapes (sorry, I just couldn’t help the reference to Lord of the Rings, among so many other incredible, breathtaking vistas: natural, man-, Hobbit-made, or otherwise)!
Pip Patterson, of Natural Habitats Landscapes, tells us that Takapuna is now home to New Zealand’s newest and most innovative venture, The Department Store, providing a multi-dimensional fashion, art and beauty experience across three floors, now featuring a dramatic greenwall.
Completed in mid November, 2009, one of the greenest triumphs of the new store - which is also a New Zealand first – is the large, vertical, interior garden or ‘Green Wall’ in the Stephen Marr Salon on the top floor.
Spearheaded by Stephen Marr, Karen Walker and Dan Gosling from Black Box, the Green Wall was designed by Katie Lockhart and installed by Natural Habitats Landscapes. The Department Store showcases the very best of fresh, creative New Zealand brands, and has embraced an international level of retail thinking by designing this unique space with emphasis on our environment.
The Green Wall is a natural extension to Stephen Marr’s environmental commitment and is unique in that it is double-sided and measures 10 metres long by 2 metres high, boasting well over 1,000 individual plants.
The Green Wall divides the upper level, promoting unique spaces that can be used for presentations such as fashion shows. The building has had skylights installed to ensure the wall is given as much natural light as possible and the use of supplementary man-made lighting is kept at a minimum. Although already stunning, the green wall is initially sparse as the plants adjust and dig in to their newly created habitat, full coverage is expected within six months or so.
Note: We get a lot of press releases claiming to be “firsts” in many respective fields – and we rely upon readers like you to set the record straight if this is not the case. Do you know of another green wall in New Zealand that came before this beautiful one? Let us know!
In any case, visit Natural Habitats Landscapes to learn more. See the greenwall profile in The Greenroof Projects Databasehere - and after many green wall entries to date, do you think it’s time to adjust the name of this database to perhaps “The Greenroof & Greenwall Projects Database”? Stay tuned in the New Year!
Did you know that yesterday, December 3, was “National Roof Over Your Head Day?” I didn’t, but now I’ll put it on my calendar for 2010. Similar, I guess, to Thanksgiving, on this day we are supposed to appreciate the things we have, starting literally with the roof over our heads. For most of us, a roof over our head means living in a home that protects us from the elements, keeping us warm, dry, safe, and cozy. Lots of us take this basic necessity of life for granted, forgetting that so many people in the world are homeless with no shelter. We’re all about greenroofs here, but of course we have to have a roof first before we can green it! As we enter the holiday season, let’s remember those less fortunate by contributing our time, goods, or money to those in need.
Ben from Listicles says we should be doing things to help others who aren’t so fortunate, like making a donation to a shelter. But on a lighter note, he writes, “We should also be thankful for things we don’t have, like unwanted and inappropriate objects on those roofs over our heads.” So they compiled some such examples of “10 Odd Things on Roofs” that you probably don’t want over your head, either, and I just had to share more of these:
See the rest of the Listicles photos here. So how about a National Greenroof Day? You never know, it could be coming one of these years! Here’s one of my own favorite Odd Things You Don’t Want on a Roof:
An exclusive of Greenroofs.com, we’re now in our third year of publishing the “Greenroofs of the World™” 12-Month Wall Calendar series. The 2010 version is now available and it’s filled with beautiful living roof projects and even more green building events from around the world than the previous last two years.
I thought it might be interesting to some of you to learn about the design process, why and how we choose the highlighted projects – the ideology behind the product, which is our first. Although I’ve been wanting to write a book (or two) for the last nine or so years, prior to the calendar all our “products” have been intellectual property offerings. And as you probably know, all of the information on Greenroofs.com is free and without subscription, following an open source philosophy of information sharing.
I had been wanting to do a calendar for years as it was an obvious add on to The Greenroof Projects Database as well as complimentary to our Upcoming Events section where we list conferences, workshops, presentations, etc., from around the world. So, voilá! 2008 marked the first year of the Greenroofs of the World™ 12-Month Wall Calendar series. How do we select our featured projects? From our website Sponsors, which is the highest level of advertising we offer on Greenroofs.com. It’s our way to highlight fabulous examples of sustainable roof design and thank these companies who back us up by marketing their ecologically friendly products and services with us. Each chooses their desired month on a first come, first serve basis. I ask for two of their favorite projects each along with several shots each. Then the fun starts! I try and represent different types of greenroofs, sizes, and geographic locations within the U.S. and the world – and of course, the quality of the photo is a huge factor. This is what is most time consuming! We include a short description under each photo, and do our best to list all major designers/manufacturers of record, including the Sponsor.
As you know, greenroofs can be used at any scale, and in the past our smallest featured vegetated roof came in at 52 sf here in Atlanta, Georgia (2008), and the largest was a whopping 765,000 sf in Zaragoza, Spain (2009). For 2010, Calendar projects range from 1,000 sf in Manhattan, New York to 113,000 sf in Minneapolis, Minnesota, see below:
In addition to displaying eye-catching greenroofs, we also desired an eco friendly product, and I feel like we do create a truly eco-chic calendar! Our 11″ x 18″ full-color glossy 12-month wall calendars are printed on 50% recycled paper with 25% post consumer waste using soy inks. We use The Messenger Press of Carthagena, Ohio where Randy Heitkamp does a great job of printing excellent quality work – and we recommend him highly.
This year we decided to go global, and you can purchase the 2010 Calendar on Amazon.com as well as from us directly. But I will say that you’ll save money by ordering through us at only $12.95 each, with free shipping in the contiguous U.S. and Canada (contact us for international shipping rates). And there are quantity discounts, too.
The 2010 Greenroofs of the World™ 12-Month Wall Calendar will make a great inexpensive Christmas/Holiday gift or stocking stuffer (well, if you have a really wide stocking!) for all you greenroof aficionados out there. See our Press Release here, where you can view each project highlighted in The Greenroof Projects Database. And find out the details for ordering here.
As a final reminder, those of you wishing to present in London, UK, this September 15-16, 2010 at the World Green Roof Congress, you need to submit your abstracts by this Friday, March 12! Abstracts are invited for submission on a range of topics.
Although roof gardens in various forms have been around for decades, I couldn’t find many examples of built or proposed greenroofs (if you know of others, please let us know!). One important one is presently under construction - the new International and Domestic Terminal at the Chennai International Airport has many environmentally friendly features. The New York team led by Frederic Schwartz Architects and Gensler with Hargreaves Associates and India-based

Completed in the fall of 2001, the Heinz 57 Center was the first vegetated roof in downtown Pittsburgh, where executives enjoy sweeping meadow vistas wrapping their offices and blanketing the thirty-foot-wide terrace. Four informal seating areas constructed with high-density recycled plastic lumber decking and concrete paving blocks provide informal gathering spots; by all accounts the colorful corporate roof garden is a hit!
Steven relates how the Heinz 57 Center plant selection encompassed “32 xeric species from nineteen plant genera, including six North American natives; approximately one-third of the plants are sedums, and the balance is a range of herbs, meadow grasses, and meadow perennials that provide differences in plant height, texture, and bloom color.”
Completed in mid November, 2009, one of the greenest triumphs of the new store - which is also a New Zealand first – is the large, vertical, interior garden or ‘Green Wall’ in the Stephen Marr Salon on the top floor.
