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.com”™s “This Week in Review” on GreenroofsTV: June 10, 17 & 24, 2011

June 27, 2011 at 4:05 pm

Each week you can expect to learn What’s New here on  Greenroofs.com through our “This Week in Review” video.  After a summer vacation, here’s the transcript from June 24 which also covers the weeks of June 17 & 10, 2011 from our daughter, Anjuli –  click on the photo below to see the video, or here.   Enjoy!

–   Hello, I’m Anjuli Velazquez and welcome to This Week in Review for this week, June 24th 2011, as well as for the past two weeks since I was gone for a little summer break, on  GreenroofsTV.

–  Projects of the Week

–   Our project of the week is the Hotel Ushuaïa Low-Tech Vertical Garden built in 2011 in Ibiza, Spain.  Situated in the Hotel Ushuaïa de Ibiza, the four panel eco.bin greenwall acts as a sound barrier between the open air disco, which is located in between the hotel’s central courtyard and the surrounding guest rooms.  The garden wall consists of rows of ceramic terra cotta containers whose circular openings are individually filled with growing medium and planted. Each interconnected planted ceramic has its own substrate and vegetation, and works together to create this sound-absorbent garden space.  This is the first such type of greenwall garden system in the world.  Also, the designers have selected a variety of native plants which can adapt and thrive in these Mediterranean conditions; and as you can see, they provide a multitude of colors during the year.

–   Our project of the week last week was the NYC Parks Five Borough Administrative Building built in 2007 in Randall’s Island, New York, New York. In response to Mayor Bloomberg’s visionary 2007 PlaNYC initiative, the Five Borough Technical Services division began a program of installing green roofs of various designs, realizing that they could contribute significantly to the city’s sustainability effort.  To date, the division, together with Parks’ Green Apple Corps and others, has installed 24 systems covering over 29,000 square feet of roof on the west wing of the building including Green Paks, GreenGrid, BioTrays, Bioroof, Xero Flor, and many custom designs. Five Borough’s is the only known green roof in the U.S. to feature such a vast array of distinct systems side-by-side, which vary by types of growing medium, depth of growing medium, and plant selection.  And there are also other non-traditional green roof systems here including a green wall, container systems, a “walkable” atrium system, as well as planters on top of parapet walls.  By the way, look for a very in-depth look at this roof as our Guest Feature Article coming very soon!

–   Our project of the week for June 10th was the Ruthven Garage built in 2010 in Tacoma, Washington.  In 2010, Jenny Ruthven was a horticulture student at Oregon State University, and after graduating found employment within the green roofing industry and wanted to design and install her own greenroof, and her parents’ garage was the perfect spot.  With the help of family and friends, they had to first add some additional structural support to the garage and replace the 29+ year old shingles. Then, they used a custom made blend of soil which ended up consisting of about 52% inorganic and 48% organic.  Inorganic was all pumice, with a bit of perlite thrown in. Half of the organic component was cedar grove compost, and the rest was coconut fiber, peat moss, mushroom compost, chicken compost, and steer compost. They planted 432 plants, with about 60 different species and varieties total.  Looking back now, Mom Sandra says that she  figured that she’d really like her greenroof, but had never   anticipated how much.

–   To learn more about the Ruthven Garage greenroof, type in project ID #1150 in our Projects Database, the NYC Parks Five Borough Administrative Building greenroof, project ID #787 and as always for our current project of the week, this week being the Hotel Ushüaia Low-Tech Vertical Garden, click on our project of the week photo on our homepage.  And, you can also always go to our Sky Gardens Blog and read Linda’s expanded post about our project of the week every week!

–   “In the News“

–   Julia Johnson of the Ottawa Citizen reports on “Old film treasure preserved in federal news archives building.”  Earlier this week, Library and Archives Canada unveiled its new $14.7-million preservation facility for nitrate film on the government’s Shirleys Bay campus.  The new building now houses 5,575 reels of nitrate film dating back to 1912.  Archivist and librarian of Canada, Daniel Caron says that the new facility was also designed to be environmentally friendly, including efficient mechanical systems, insulated walls and a greenroof.  And Mario Gasperetti, the archives’ manager of strategic accommodation adds that the greenroof helps with keeping the vault cool by reducing heat exchange and instead of using manicured grass on the roof, it is designed to look exactly like the meadow landscape surrounding the building.

–   Julie Young of the Richmond Times-Dispatch talks about “Burnt-out home goes from ashes to awesome.”  She says a few years ago, the 1920s row house on Grove Avenue was an “architectural corpse.  Its skeletal remains consisted of a disfigured facade, broken bones and devastating internal damage.”  Then along came Dr. Susan Miller and her husband Dr. Kenneth Kendler to the rescue.  In 2008, they signed on to breathe life back into this burnt down home.  Over the next two years, “The Phoenix” was reborn and filled with green eco-friendly sustainable features like their own greenroof, the 25 foot tall green wall located in the home between the dining room and great room, thirty photovoltaic  roof panels, solar panels, concrete countertops flecked with reclaimed glass and rocks their now-adult children collected as kids, and much more.  The living wall ecosystem was designed by Scotty Guinn Dilworth of SG Designs and installed by Capitol Greenroofs who also installed the roof-top garden.

–   Ted Kortan of NewsNet5.com announces “Tremco Incorporated headquarters dedicated in Beachwood.”  Tremco Incorporated, a building products and solutions company, and subsidiary of RPM International, dedicated its renovated 40-year-old corporate headquarters last week.  Tremco said the project has resulted in a “high performance” building that is substantially more efficient, cost effective, and sustainable than the previous headquarters, with features like their vegetated roof with almost 1,600 plants and the area’s first solar powered electric car charging station.  Joining with company officials at Tremco’s Green Road campus for the dedication were Ohio Governor John Kasich, U.S. Senator Rob Portman, U.S. Congresswoman Betty Sutton and Beachwood Mayor Merle Gorden.

–   Sandy Bauers of Philly.com says “A tiny step forward for green roofs in Philadelphia” includes “a cheerful puff of plant life atop a bus-stop shelter.”  Tiffany Ledesma Groll, the project’s coordinator said, “We basically see this project as an opportunity to inspire homeowners.  A lot of the green roofs that are really fabulous and gorgeous are on high-rises” – which most people never see.  She goes on to say, “We thought it would be fun to bring it down to eye level.”  Last week, workers from Roofmeadow, a Philadelphia green roofs company that did the installation pro bono, were busy topping the shelter with its “mini-oasis.”  They planted a fuzz of pink dianthus, multicolored portulaca, and sedum and Roofmeadow also has committed to maintaining the roof for its first two years.  Charlie Miller, president and founder of Roofmeadow, said the roof “will give people a sense of familiarity…how it contributes to the quality of life.”  His son, Ari, designed the installation so it could be replicated as a “kit” for other bus-stop roofs in the city.
