’s “This Week in Review” on GreenroofsTV: April 6, 2012

April 7, 2012 at 9:42 pm

Each week you can expect to learn What’s New here on through our “This Week in Review” video.  Here is the transcript from April 6th, 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 April 6th, 2012 on GreenroofsTV.

Project of the Week

–  Our project of the week is the Salmon Creek School & Environmental Center, built in 2009 in Freestone, California.  This LEED ® Platinum certified school is the first public school in California to receive this highest level of LEED ® certification.  The educational building is also a community and environmental education center that focuses itself on place-based learning and developing eco-literacy among its students and parents.  SYMBIOS eco-tecture worked with students, administrators, community and environmental groups to design and plan a living roof that would be educational and functional.  The cafeteria food comes from the organic garden; the walls are not only natural plaster but also clean the air; and natural light is strategically introduced to keep the kids perky and to help heat the building in the winter.

In the summer the green living roof keeps the school cool, in the winter keeps it warm and creates a habitat for wildlife all year long.  Biodiversity was emphasized in the planting scheme of the greenroof, which included 12 species of drought-tolerant succulents, three of which are native to California.  Salmon Creek that runs through the school’s property is currently undergoing a multi-year restoration project to restore the Coho Salmon populations and therefore a net zero stormwater discharge rate was mandated.  Other sustainable features of the building include passive solar design, daylight harvesting, a 30 kilowatt PV solar system, eco-plasters and floor finishes, reclaimed lumber and recycled content steel framing low-water use fixtures, and more.

Industry News

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

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

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

– “In the News“

–  Peter Raabe of the American Rivers Blog, has “A Vision Of Green Roofs In Durham, NC.”  He says “North Carolina has a stormwater problem.”  Many of its rivers are polluted due to stormwater runoff.  The state has put rules into effect to clean up its act and Durham is at the center, on one side, Jordan Lake and the other, Falls Lake reservoirs, and both have strict clean up requirements due to the poor land use practices around them.

Beyond stormwater runoff reductions, greenroofs could offer many benefits to Durham like reducing roofing maintenance, improving building energy efficiency, reducing urban heat island effect, improving habitat for wildlife, improving air quality and the potential creation of a green economy work force.  American Rivers has partnered with Downtown Durham, Inc. and they put on a forum for more than fifty city and business leaders that explored the potential of greenroof enhancements in Durham.  The forum created momentum within Durham and they are on their way to creating a more sustainable city.

– Texas A&M University talks about “Interdisciplinary green roof effort to engage wide variety of students.”  Next fall, 1,000 students from a variety of academic programs, including architecture, construction science, environmental geosciences, environmental studies, landscape architecture, horticulture and meteorology at Texas A&M, will begin working together on an interdisciplinary, three-year project to install and monitor a greenroof and living wall atop a campus building.  Assistant professor of landscape architecture and leader of this project,   Texas A&M University  , says this initiative is aimed at preparing students to become leaders in energy conservation and resource management.

In the project’s first year, students will have learning experiences beyond a traditional classroom setting, as they build, install and maintain all of the elements of the greenroof, including physical structures, standard meteorological and soil monitoring instrumentation, planning and plant maintenance, manual measurement and associated live and stored data processing and display.  This project is funded by a $100,000 Texas A&M reallocation grant for enhancing students’ preparation for the workplace and society through high-impact learning experiences.

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 17: Sustainability in Plant Production

April 4, 2012 at 6:43 am

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 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.
