Today we have the pleasure to air Lluís Recasens Pahí’s “Sustainability in Plant Production” from our inaugural 2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

We first started corresponding with Lluis early last year when he contacted us very enthusiastically about the in depth work he is doing in the Catalan region of Spain.  He wanted to submit a Guest Feature Article with us about his plant research and testing yet once we decided on hosting the Virtual Summit, I felt this would make a great topic.

Although Lluis speaks Spanish, Catalan, Portuguese, Italian and English, he preferred to present his video in Spanish.  So you will find this is our first video presented in another language, Spanish, with English subtitles (translated by me) - Chinese being the second (not translated by me!), coming up soon.

Lluís Recasens Pahí lives in Tarragona, Spain, is a horticultural engineer, and co-founder of the first Escuela de Horticultura y Jardineria de España (Horticulture and Gardening School of Spain), 1982-1988.

Lluis has worked in various high level managerial positions within the fertilizer (controlled and slow release fertilizers) and ornamental horticulture industries for The Scotts Company and Nosterra Ibérica S.A Europa.  Presently, Lluís is Profesor de Horticultura (Professor of Horticulture) at the Institut d´Horticultura i Jardineria de Reus (Institute of Horticulture and Gardening of Reus) in Catalonia, Spain, and he also is a consultant on various projects including maintenance of greenroofs and greenwalls.

In Lluís’ very informative video presentation, sustainable crop production is addressed with a focus on greenroofs and walls in the areas of Reus, Ampurias, Guadalajara, Tarragona, and Barcelona, Spain, utilizing plant selections with minimum agronomic requirements (low demands on maintenance, water intake, and disease control) as well as contemplating the use of environmentally friendly and respectful materials.  Using these technologies will ensure more sustainable parterres, greenroofs, and greenwalls through their material selection and plant diversity.

He says that by using biodegradable materials and encouraging recycling and biodiversity, we reduce our water requirements and the maintenance program is respectful of the environment and the ecosystems, plus we contribute to the implementation and popularization of these sustainable processes.

Today we have the pleasure to air the panel presentation “Vertical Agriculture: A Global Movement Starts Locally, from Wall to Table” with George Irwin, Tom Ferraro, and U.S. Congressman Tom Reed from our inaugural 2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

We’re happy that George is an editorial contributor to Greenroofs.com as The Green Wall Editor (2008).  Outspoken and sometimes even a bit brazen, he always shoots from the hip and writes from the heart and George has become a true friend and staunch supporter of ours.  With George’s excellent work combining his greenroof and greenwall systems with education for youth and the underprivileged plus his implementation of vertical food farms, I felt he would make an excellent leader of a panel on the subject.

This panel of experts addresses how urban agriculture is on the rise globally – up the walls and on rooftops.  Fresh, local crops benefit the entire community for many reasons.  U.S. Congressman Tom Reed from the 29th district of New York, Tom Ferraro, CEO of Foodlink – a national network of 200 food banks – and George Irwin, CEO of Green Living Technologies International (GLTi), provide interactive conversation and commentary concerning the impact of education, economics and opportunity around local food production with green walls and roofs.

Rochester-based GLTi started in New York City and has since grown nationally and internationally through education and collaborative hands-on projects with local youth, the underprivileged and disadvantaged in New York and Los Angeles and with business partnerships in Santiago, Dubai, and beyond to include their Food Factory and more.

George Irwin is founder and CEO of Green Living Technologies International, LLC (GLTi), a privately held company manufacturing patented Green Living Walls and Green Living Roofs, and is a global pioneer in vertical agriculture.  Prior to founding GLTi, George was a landscape contractor for two dozen years.  He holds a degree in education and his mission is to help create sustainable solutions to the challenges of food insecurity and the dearth of job opportunities for at risk youth throughout America’s inner cities. His efforts have earned him recognition as an official education partner for the New York City Department of Education and additional higher education facilities, with the development of a GLTi-dedicated degree track in “Green Tech” education at secondary schools in multiple states.  The first high school is scheduled to open in September of 2012.  George is also a contributing editor on Greenroofs.com (2008); he is The Green Wall Editor and talks about his own experience as well as industry happenings within the field.

George is the Moderator for “Vertical Agriculture: A Global Movement Starts Locally, from Wall to Table.”

Tom Ferraro is Executive Director of Foodlink.  Founded in 1978, it has grown to serve a 10-county area in the Greater Rochester area.  As a founding member of Feeding America, Foodlink is part of a national network of 200 food banks whose mission is to provide hunger relief, eliminate the root causes of hunger, improve health and promote economic development.  They do this through the distribution of food to a network of agencies and by empowering individuals through nutritional and agricultural programs.  Foodlink’s vision is to build a hunger-free community and sustainable regional food system in which every individual has access to nutritious food and is empowered with the tangible skills to lead a healthy and productive life.  Locally, they rescue and redistribute over 11 million pounds of food annually to a network of 450 programs.  Today, the food bank’s network of agencies serve 102,000 meals each week, or over 5 million meals annually to an estimated 125,000 different people.

U.S. Congressman Tom Reed was elected to represent the 29th District of New York in a special election held November 2, 2010.  He took office during the “lame duck” session of the 111th Congress and began his own full two year term in the 112th Congress on January 5, 2011.  In June 2011 Congressman Reed was recently appointed to the Committee on Ways and Means and serves on the Human Resources and Oversight subcommittees of Ways and Means.  Tom previously served on the Rules, Judiciary, and Transportation and Infrastructure committees.  He graduated from Alfred University in 1993 with a degree in Political Science and from the Ohio Northern University College of Law in 1996.  Tom says, “Job creation and the nation’s financial health are the most important challenges facing the country and upstate New York.”

After the presentation on the second day of the 2011 Greenroofs & Walls of the World™ Virtual Summit, George Irwin and Tom Ferraro were available for the live Q & A session; the transcript was available archived for 30 days for participants of the Virtual Summit – unfortunately, we do not have it available now – one of the reasons to participate in this year’s Virtual Summit!

Each week you can expect to learn What’s New here on Greenroofs.com through our “This Week in Review” video.  Here is the transcript from March 23rd, 2012 from our daughter, Anjuli – click on the photo below to see the video, or here.  Enjoy!

- Hello, I’m Anjuli Velázquez and welcome to “This Week in Review” for March 23rd, 2012 on GreenroofsTV.

- Project of the Week

- Our project of the week is the WaterShed House, built in 2011 in Washington, DC.  This prototype solar house entry from the team at the University of Maryland won the U.S. Department of Energy 2011 Solar Decathlon – an award-winning program that challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive.  WaterShed is a solar-powered home inspired and guided by the Chesapeake Bay ecosystem, interconnecting the house with its landscape to promote sustainability and ecosystem protection.  Two rectangular modules form the house, and it is capped by a split-butterfly roof, which is well suited to capturing and using sunlight and rainwater.

Key features of the house include a greenroof to retain stormwater and reduce the volume and velocity of run-off, and constructed wetlands to filter stormwater and grey water for reuse.  The south module of the WaterShed House has an extensive greenroof supplied by the LiveRoof® Hybrid Green Roof System with LiveRoof Lite modules.  LiveRoof modules feature the company’s Soil Elevator™ and Moisture Portal™, horticultural innovations that establish a greenroof as a cohesive ecosystem.  The LiveRoof design unifies the entire installation into a naturally functioning biological system.  Natural function maximizes plant health, long-term sustainability, rooftop aesthetics, roof membrane protection, and environmental benefits.

- “In the News”

- Richard Lee, of the Danbury News Times, reports on “LaurelRock adds ‘green walls’ to its offerings.”  Earlier this week, LaurelRock, a Wilton-based landscape design and installation business, hosted George Irwin, CEO of Green Living Technologies International [and one of our contributing editors], where he demonstrated how his company creates green walls.  LaurelRock is the exclusive installer of GLTi’s patented panel technology in the company’s service area.  LaurelRock President Burt DeMarche believes gardeners will be interested in GLTi’s “edible walls” concept, because they can produce fruits, vegetables, and herbs in an easier way for gardeners who want to grow their own food but don’t have the time or energy to do it the “old-fashioned way.”

At the Millstone Farm presentation, George stood by a 2×6 foot frame holding plants including moss, waffle leaf, palm, ferns and more; and he said, “this wall has light indoor plants which are relatively low maintenance.  They provide an incredible opportunity to clean the air in the room” and that his “idea was to mimic Mother Nature.  It provides an opportunity for roots to migrate from cell to cell.”  Green Living Technologies International developed a program with the Innovation Charter School in Harlem, where students learn the technology, preparing them for work a companies like LaurelRock.

- Bill Marken, of Garden Design Magazine, talks about “Green Roofs.”  He reflects on the evolution of greenroofs being just an “eco-fantasy” to becoming the current “eco-solution.” He says greenroofs have become natural fits for many public buildings, thanks to the environmental and financial benefits like energy efficiency, storm-water management, sound insulation, while also being habitats for birds, bees, butterflies, and other insects and animals that help our environment.  Residential greenroofs will accomplish most of the same environmental goals but the financial benefits will take longer to realize.  There are do-it-yourself kits nowadays but developing a sustainable green roof usually calls for someone who knows the structural demands, assembly systems, drainage, local conditions, plants, and maintenance.

To explore the possibilities of having a greenroof of your very own, author Ed Snodgrass, and contributing editor here at greenroofs.com, suggests starting out with a doghouse or a birdhouse.  He says, “starting with a birdhouse is a good first step to getting your feet wet and understanding the limits – and opportunities – of growing plants in such a shallow root space.”  And from there, there’s no place to go but up!

- Project of the Week

- Our project of the week is the Soleil @ Sinaran built in 2011 in Singapore.  These 36-story twin towers offer trendy professionals and young couples a 50 meter lap pool, two spa pavilions and eight entertainment pavilions – all are covered with extensive greenroofs.  They also have themed lounges and expansive sky gardens, with gymnasiums on the 20th floor of each tower.  The Soleil @ Sinaran has been awarded the BCA Green Mark Gold showing collaborative effort on its part to achieve sustainability in the built environment.

Elmich’s greenroof system contributed substantially to the condominium’s green initiative and the 1,150 square meter greenroofs give the condos a resort-like ambiance while protecting and prolonging the waterproofing membrane on the rooftops and mitigating Singapore’s urban heat island effect.  The Elmich Greenroof is both lightweight and easy to install and was the ideal system for this project.  Elmich Greenroof is comprised of a VersiDrain® 25P water retention and drainage layer, a geotextile filter layer and EnviroMix® GR – a primarily inorganic soil-less lightweight planting media – and drought-tolerant plant species that require little or no maintenance.

Snodgrass, one of our contributing editors here on Greenroofs.com.

Judge Greg Williams says its “a real trailblazer because it is the only in-depth guide to do-it-yourself green roofs, with plenty of case studies to build confidence and provide ideas for homeowners.”  Another judge, Fiona Gilsenen was impressed with the authors’ “approach, ethos and emphasis on using green roofs to encourage biodiversity, plus making it doable in a wide range of places.”  Congratulations, guys!  Check our greenroof bookstore for more info on this book and other greenroof and greenwall related books and magazines.

- Jennifer Maloney of the Wall Street Journal talks about what’s “Fun for Kids, Good for the Waterways.”  She says New York City has enlisted trees, greenroofs, and massive tanks in its effort to reduce the untreated wastewater that overflows the city’s waterways each year and now it’s looking at schoolyards.  The city’s Department of Environmental Protection is developing a plan with the national non-profit group, Trust for Public Land, to build up to 10 green playgrounds that will capture the first inch of rain in every storm.

Five proposed schoolyards in Brooklyn and Queens are going through soil tests and if they are picked, will be transformed into public playgrounds with features like rain barrels, raised gardens, porous pavers and an under-layer of gravel that holds water during a storm then seep gradually into the ground.  A recent project, at P.S. 164 in Borough Park, Brooklyn, served as a pilot of sorts for the new initiative, because it includes some of the same rainwater-retention features, including a greenroof.  The first few new playgrounds should be open to the public by the end of next year.

- Project of the Week

- Our project of the week is the Epcot Living Wall built in 2011 in Orlando, Florida.  Epcot® theme park is one of four theme parks at Walt Disney World Resort, and is divided into Future World and World Showcase.  Located in the Festival Center, the interior EcoWall was created as part of the 2011 Epcot® International Flower and Garden Festival, and now serves as a dual purpose for Disney’s Epcot Food and Wine Festival as well, and is permanently on display in the park.

It features 1300 tropical plants and ferns and during the Food and Wine Festival edible plants, like pineapples, dwarf banana trees and citruses, are incorporated as part of an interactive display to show unique spaces, saving solutions in urban farming.  The EcoWall uses a unique and lightweight combination of inorganic growing medium into the design.  The material locks in moisture and nutrients, which reduces the amount of resources required to sustain healthy plant growth.  Guests get to walk through the living wall as they enter and exit the Festival Center.

- “In the News”

-  Hosea Sanders of ABC7Chicago.com, reports on “Chicago produce firm runs earth-friendly operation.”  Testa Produce is a 100-year-old family business and has recently constructed a new warehouse that features a barreled greenroof, a 238-foot tall wind turbine, and a solar hot water system.

Testa Produce President, Peter Testa, said the greenroof and wind turbine are his two biggest accomplishments and that the electricity the turbine produces with save him as much as $80,000 a year.  Testa Produce has also implemented a long list of operational changes to reduce waste, such as switching to reusable mesh pallet wraps from disposable plastic and recycling all cardboard.  They have earned a LEED Platinum certification.  You can visit the full article and watch the local news clip.

- Samantha Marcus of the Allentown Morning Call, talks about “Hospitals, schools pursue energy technology with savings in mind.”  She says “with energy bills reaching as high as $10 million, conservation is not just about the environment.”  The greenroof on top of St. Luke’s Hospital and Health Network’s Heart and Vascular Center in Bethlehem, Pennsylvania, is doing its job: improving air and water quality while insulating the building.  Inside, systems detect ambient light coming in and close the shades accordingly.

Same smart energy savings are happening at the Lehigh Valley Health Network, which has ultraviolet lights to extend the life and efficiency of air handlers by preventing bacteria and mold from building up on heater coils.  Greenroofs and solar arrays are the most visible ways buildings are saving on energy costs but high-efficiency motors and boilers are also hard working inside buildings to help promote savings.  Lehigh Valley Healthcare has installed two 300,000 kilowatt solar arrays at its Cedar Crest and Muhlenberg campuses, with the help of local and state grants, and they’ve already seen savings.  Several schools in the area have already had energy efficient replacements and more are scheduled.

Today we have the pleasure to air Christopher Wark’s video presentation “E = MC2 of Green Roofs: Ranking Energy Benefits by Mission, Climate and Construction” from our inaugural 2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

Chris has been an editorial contributor to Greenroofs.com as The Energy Editor since 2010.  In April 2011 he completed his seven-part series entitled “Cooler Than Cool Roofs: How Heat Doesn’t Move Through a Green Roof.”  He and his wife, Wendy, have been great friends of ours since we met them in 2003 in Chicago, at the first Greening Rooftops for Sustainable Communities Conference, Awards & Trade Show.  Here they are on the Highline when we visited in New York City back in May, 2010:

Christopher Wark has 23 years of multidisciplinary engineering experience providing mechanical, analytical, and electronics support and services to manufacturers, universities and national labs.  For the past 10 years, he has focused his efforts on the development and promotion of technical solutions in architecture and construction.  Chris is currently an Associate with WSP Flack + Kurtz, managing their building analysis group.

Before joining WSP Flack + Kurtz, Chris was a Senior Energy Analyst for Viridian Energy & Environmental. Previous to that, he provided energy analysis and LEED consulting services for several companies, including subsidiaries of the Integral Group, and served as Technical Sales Manager for Mentor Graphics Mechanical Analysis Division (formerly Flomerics Inc.), offering energy and air flow analysis solutions for architectural engineers.

In 2002, Chris established SHADE Consulting/Green Roof Innovations with his wife Wendy.  With SHADE/GRI, Chris developed and marketed several innovative modular eco-roof systems, a roof system heat transfer and cost computer program, and conducted green roof system heat transfer analyses for 5 major cities and organizations.  In 2010, he developed a modular planting system in partnership with Guiyang Chuangjia High-Tech Accelerator Co. LTD in Guiyang, China.

Chris has also been involved in other thermodynamic related work, including advanced engine research and fuel cell system development at Caterpillar Inc. and laser development at Lawrence Livermore National Lab and 2 private research laser development companies.  He has presented at numerous conferences, has several articles published on a wide variety of engineering topics, and has had the privilege of working directly with several universities, including Stanford’s Center for Integrated Facility Engineering (CIFE) program.  Chris holds Bachelor’s and Master’s of Science degrees in Mechanical Engineering (with a minor in Materials Science) from Washington State University.  His graduate work focused on thermodynamics, fluid dynamics and combustion.

In Chris’ video he discusses how the amount of energy savings from a green roof is determined by a combination of its mission:  How the building spaces are used; climate:  Where in the world, where in the neighborhood; and construction:  Building size, shape, and internal design.  Best and worst candidates are examined.  During the Virtual Summit, Chris’ video presentation was followed by a live 15-Minute Live Q & A; the transcript was available archived for 30 days for participants of the Virtual Summit – unfortunately, we do not have it available now – one of the reasons to participate in this year’s Virtual Summit!

An agronomy engineer, João hails from Porto Alegre, Brazil and has been a part of the greenroof scene for quite some time now.  We met him in 2006 in Boston at the 3rd Greening Rooftops for Sustainable Communities Conference, Awards & Trade Show (now CitiesAlive).  He had an innovative modular greenroof system, Ecotelhado, which since then has blossomed into other products and has done quite well in Brasil and neighboring countries, and is now in Mexico as well.  His non-profit work has helped establish greenroofs and walls within Brazil.

Principal of Ecotelhado, João Manuel Linck Feijó’s firm offers green infrastructure solutions through the manufacture of green roof and green wall systems and consulting services.  He is also the Director of ATVBrasil, a non-profit organization working to promote green infrastructure in Brazil, which has been disseminating green roof and wall information in many cities and proposing projects of law for green roofs all across the country since 2005.  João is a World Green Infrastructure Network (WGIN) board member.

ATV Brasil is a non profit association whose objectives are to promote the construction of green roofs and vegetated walls in Brazil whose mission is to supply background information for legislation, to incentivize research, and to show the impacts of vegetated roofs in urban ecology.

I’m sure you’ll love the scenery and energy in this lively video of lovely Brazil!

Today we have the pleasure to air Wolfgang Ansel’s ”Green Roof Policies – An International Review of Current Practices and Future Trends” from our inaugural 2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

Wolfgang Ansel is a biologist who studied at the University of Hohenheim, Germany.  He is currently the Director of the International Green Roof Association (IGRA).  IGRA`s targets include the worldwide promotion of the ecological green roof idea, an international knowledge transfer in the field of green roofs and the stimulation of international standards for good practices and reliable green roof technology.  Wolfgang Ansel is co-author of different green roof books.  During the last year he was an invited speaker at congresses in Europe, North America and Asia.  One of his main areas of work is implementing green roof policies and guidelines on an international level.

In Wolfgang’s presentation he says that green roof policies are one of the basic key factors for the successful development of a green roof market.  Longstanding experiences and case studies from different countries and municipalities are creating a source of ideas that can be adapted and modified according to the needs of the local green roof stakeholders.  His video highlights success stories and failures likewise.  Information from Europe, North America and Asia will be merged into a “Best Practice Guideline for Green Roof Policies.”

Today we have the pleasure to air the panel presentation “Wind. Water. Heat. Grow. Greenroofs.” from our inaugural 2011 Greenroofs & Walls of the World™ Virtual Summit with Dr. Bill Retzlaff, David Aponte, Kevin Songer, and Joe Webb on greenroofs.tv and our GreenroofsTV channel on YouTube.

A couple I’d known for years and the others were newer aquaintances, but I was very excited to get these four professionals together – with their combined years of experience designing greenroofs in high-wind prone areas across the U.S., I knew we’d have a great discussion:

Aramis and I met Dr. Bill in 2006 at Southern Illinois University Edwardsville when I was invited to speak there through Kelly Luckett, AKA The Green Roof Guy – the president of Green Roof Blocks, a contributing editor of ours, and a good friend.  Kelly had been collaborating with Dr. Bill and his G.R.E.E.N. program – a relationship of trialing different aspects of greenroofing, including wind testing in June 2009, that has lasted for quite a few years now.  Although he hasn’t shared anything new in a few years, Dr. Bill is also a contributing editor of Greenroofs.com; you can read about his work here.

I met architect Joe a few years ago at one of the Greening Rooftops for Sustainable Communities Conferences when he talked about his emphasis on sustainability and presented on one of his greenroof projects, Cheyenne I (251 Medical Center Blvd.).  In 2008 the building with its new greenroof came through Hurricane Ike, which barreled through Houston, unscathed.

We met fellow Latin, David, in Singapore in November, 2010 when we both spoke at the International Skyrise Greenery Conference.  David talked about the similarities and differences between the climates of tropical Singapore and sub-tropical Puerto Rico.  Of course, his island is known for its prime location during hurricane season.

We still haven’t met Kevin in person (but hope to!), but were very impressed with his knowledge and experience with greenroofs in Jacksonville, Florida, having corresponded with him as well as read his blog posts and discussion board posts on native plants and wind trials.

This panel of experts say that greenroofs are impacted by wind, water and heat on an unrelenting basis.  Through wind trials and real hurricane survival stories in Houston, TX, Jacksonville, FL, Edwardsville, IL, and Puerto Rico, we have met those challenges and will discuss various projects’ responses and successes to Hurricanes Ike and (any others?). Drought, hot winds, and unseasonable 100° days can also quickly desiccate or kill greenroof plants.

Dr. Bill Retzlaff moderates discussing wind studies and plant trials for greenroofs at Southern Illinois University Edwardsville.  Joe Webb talks about his project which endured 110 to 120 mph winds and 11” of rain in 24 hours and shares water mapping and Living Building Challenge Water requirements.  Kevin Songer talks about the Outdoor Turbine Hurricane Simulator at the University of Florida, water conservation through ‘nature-based irrigation design,’ and the importance of biodiversity.  David Aponte speaks to his experience of engineering and designing greenroofs with the correct growing media and plants in hurricane-prone, sub-tropical Puerto Rico.

Bill Retzlaff, PhD, Co-Director of G.R.E.E.N., Chairman of the Research Committee of Green Roofs for Healthy Cities, Biological Sciences Professor and Associate Dean of the College of Arts and Sciences at Southern Illinois University Edwardsville (SIUE), has conducted wind tunnel testing of green roof systems and contributed research data for the new green roof wind uplift standard.  In addition, a 16,000 sf green roof on the SIUE campus has just experienced a wind “event” with no uplift or damage.  Dr. Bill is also a contributing editor on Greenroofs.com (2006); he is the G.R.E.E.N. Editor and talks about the various trials at the SIUE Green Roof Research Center.

David L Aponte, MSCE, GRP has a Master’s of Engineering in Water Resource Engineering and a Bachelor’s of Science degree in Environmental Engineering with several years experience in green roof design and the construction industry.  He is founder of PR Green Design, Inc. (PRGD) which is responsible for 80% of all the green roofs built in the island of Puerto Rico.  Projects range from small ecological roof to big scale intensive greening.   Since 1996, more than 150,000 sf of green roofs have been installed in Puerto Rico, but not all have survived the harsh environment of the tropics, especially in the extensive category.   As this new wave of green roof construction is reaching the Caribbean market many doubts and misconceptions have taken over local designers.   Should green roofs be designed here equally to those in northern climates?

Kevin Songer’s passion is restoring ‘volumetric green’ to the urban core, designing green roofs for MetroVerde.  MetroVerde’s green roof designs are structured for cyclone and hurricane impacted areas with native plants.  He holds a B.S. in Biology and a Juris Doctor in law (environmental and land use).  Kevin writes a daily green roof blog, Living Green Roofs.  He is a LEED BG+C and an ISA Certified Arborist & Municipal Specialist Arborist.  Follow @kevinsonger on twitter.

Joe Douglas Webb, AIA, is the principal of a small Houston based architecture and planning firm, Webb Architects, that specializes in commercial architecture, planning and city design projects.  Registered to practice architecture in 14 states, he is currently chair of Blueprint Houston, a past president of AIA Houston, a member of APA, USGBC, ULI and a NCARB Certificate holder.

After the presentation on the second day of the 2011 Greenroofs & Walls of the World™ Virtual Summit, Dr. Bill, David, Joe, and Kevin were available for a live Q & A session; the transcript was available archived for 30 days for participants of the Virtual Summit – unfortunately, we do not have it available now – one of the reasons to participate in this year’s Virtual Summit!

Each week you can expect to learn What’s New here on Greenroofs.com through our “This Week in Review” video.  Here is the transcript from February 24th, 2012 from our daughter, Anjuli – click on the photo below to see the video, or here.  Enjoy!

- Hello, I’m Anjuli Velázquez and welcome to “This Week in Review” for February 24th, 2012 on GreenroofsTV.

- Project of the Week

- Our project of the week is EnBW Energie Baden-Württemberg AG built in 2009 in Stuttgart, Germany. EnBW supplies its customers with reliable, economical, and environmentally-friendly electricity and heat. Its 16-story Administrative Complex has three wings and a high-rise with many extensive greenroofs and useable intensive greenroofs over their underground parking. Designed by architects RKW, the EnBW City consists of nine buildings including a 60-meter-high skyscraper, a parking garage with 1,200 parking spaces, the Forum, Piazza, meeting rooms, canteen, and more. The design of the courtyards is devoted to various energy topics: wind, light and the water court; and an adjacent nature preserve offers rest and recreation for visitors and staff.

- EnBW City uses energy more intelligently and efficiently and exceeds the strict requirements of the Energy Conservation Act with cutting-edge technologies such as window shading, ventilation, cooling, lighting domes and geothermal energy. Various Optigreen system solutions were used on the project including: “Natural Roof,” “Garden Roof,” “Public Roof,” and “Landscape Roof.” The EnBW complex was a challenging project for Optigreen and the installing partners, yet has resulted in a very lovely “state of energy technology” workplace.

-  Kevin Collison of The Kansas City Star, reports on “Brad Pitt’s foundation to help redevelop Bancroft School.” Brad Pitt’s Make it Right Foundation is reaching out beyond New Orleans to Kansas City to renovate the long-closed 103-year-old Bancroft School and turn it into 29 affordable apartments with a 6,250 sq ft community center. A new 21-apartment building is also in the works. And, there will be a secure garage for 50 vehicles that will have its own greenroof.

Bancroft renovation supporters say this could be a good model for how to redevelop other closed schools. This project will be built to LEED Platinum environmental standards and marks the first major project to be built in the Green Impact Zone. President of the Historic Manheim Neighborhood Association, Sandra Hayes, said “this project will help because it will become a community campus with the Truman Medical Center programs, senior activities, day care, job training, arts and crafts – that will change the whole fabric of the neighborhood.” Hopefully this is just the first of many green renovations to help communities around our country.

- PRWeb announces “Brooklyn Grange To Build A Rooftop Farm at the Brooklyn Navy Yards: World’s Largest Rooftop Farm To Add Second, Larger Location in Spring 2012.” New York City’s first commercial rooftop farm, Brooklyn Grange, will be installing a 45,000 sq ft productive greenroof on Building No. 3, 63 Flushing Avenue, at the Brooklyn Navy Yard.

The Green Infrastructure Grant from the Department of Environmental Protection will be contributing the funding of this project in large part; and staying in line with the DEP’s mission to reduce combined sewage overflow and improve water quality in New York City, this second location will more than double the current farm’s acre of growing space and manage more than one million gallons of stormwater. Brooklyn Grange will work with the Brooklyn Navy Yard Development Corporation and City Growers, the farm’s educational non-profit, to create training programs, community partnerships and provide fresh produce, like heirloom tomatoes, herbs, peppers, kale, and more to the surrounding area.
