Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 15: E = MC2 of Green Roofs: Ranking Energy Benefits by Mission, Climate and Construction

March 21, 2012 at 9:02 am

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!

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 14: The Work of ATVBrasil

March 14, 2012 at 8:50 am

Today we have the pleasure to air  João Manuel Linck Feijó’s “The Work of ATVBrasil”  from our inaugural  2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

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!

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 13: Green Roof Policies – An International Review of Current Practices and Future Trends

March 7, 2012 at 8:45 am

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.”

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 12: Wind. Water. Heat. Grow. Greenroofs. Panel Presentation

February 29, 2012 at 4:20 pm

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!

Note: Due to technical and other difficulties from the second party vendor who filmed our illustrious panel of four, this video did not have our standard 2011 Greenroofs & Walls of the World™ Virtual Summit branding initially, including the shots from Google Earth. We did, however, add it to the four affected panel presentations so that they would be effectively identified for posterity.
