Each week you can expect to learn What’s New here on 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, 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!

GPW: U.S. Tax Court

April 27, 2011 at 10:58 pm Project of the Week: 4/25/11
U.S. Tax Court
Washington, DC, USA
5,500 sf. Greenroof

Year: 2008
Owner: U.S. General Services Administration
Location: Washington, DC, USA
Building Type: Municipal/Government
Type:  Extensive
Single Source Provider
Size: 5,500 sq.ft.  
Slope: 1%
Access: Inaccessible, Private

Project Description & Details

The United States Tax Court, one of a number of notable General Services Administration’s greening projects, was recently reroofed with a Barrett Company extensive assembly, adding to the growing federal green roof inventory within the Capitol District.  The green roof initiative is reducing the storm water runoff volume while providing the many other environmental contributions that green roofs are known to provide including increased roofing longevity, carbon dioxide-oxygen exchange, reduced interior noise pollution and reduction of the urban heat-island effect.

The project actually has two wings with three green roofs totaling 5,500 sf of vegetated area: two green roofs on the north wing and one on the south wing.  Two succulent plugs per sf were planted including Sedum album; Sedum spurium ‘Fuldaglut’; Sedum kamtschaticum; Sedum sexangulare; Sedum reflexum ‘Blue Spruce’; Delosperma nubigenum, and Sedum rupestre “˜Angelina’.  An erosion control mat was placed on top of the extensive growing media.  Not publicly accessible, the U.S. Tax Court’s Greenroof-Roofscapes ® provides a visual delight to its high-rise neighbors.

Designers/Manufacturers of Record

Waterproofing & Greenroof System: Barrett Ram-Tough 250DM -“Greenroof-Roofscape ®” Extensive Green Roof
Architect: MTFA Architecture, Inc.
Waterproofing & Greenroof-Roofscape ® Installer: Cole Roofing Company, Inc.
Greenroof Installation Management & Maintenance: Greg Long, Capitol Greenroofs

Although the square footage for the vegetated area is 5,500 sf, Barrett Company provided a total area of 21,300 for the hot fluid applied roofing area.  Cole Roofing was brought in as Barrett Company’s Greenroof-Roofscape ® Installer.

Here are some photos of the December, 2008 installation:

As you can see from these photos a gravel bucket was hoisted to the roof and fall protection fencing was set up around the receiving area.  The growing medium was compacted using a 200 lbs. rolling drum, and 2″x10″ boards were used to screed it to ensure proper depth.  Then the growing medium was saturated and compacted to reduce wind erosion.  And finally, an erosion control mat completed the plantings.

Here’s what the roof looked like right after, in December 2008 and then the following season in late April and May, 2009:

Remember that planning in a busy downtown district can be tricky, but extremely important for all of the material material providers on a project.  Greg Long, seen below, says:

“Staging the materials is often the most difficult part of the project and minimizing the amount of times that you move material often determines whether a project will be profitable. “

It sounds like everyone is pleased with the way the project has fared.  Referring to Tim Barrett and Greg Long of Capitol Greenroofs, Bill Cole of Cole Roofing says:

“Greg and Tim have been great.  We hired Greg to oversee our men during the installation and then continue the maintenance.  He has done an excellent job.”

Vote for the ASLA Green Roof Page to Win a Webby!

April 15, 2011 at 11:04 am

Jim Lapides, the Manager of Public Relations for the American Society of Landscape Architects (ASLA) – of which I’m an associate member – shared some exciting news with me yesterday:  The ASLA’s new Green Roof page is a Webby Award finalist under the “Society>Associations” category.

How fitting since April is National Landscape Architecture Month, when landscape architects plan special activities to be visible in their communities across the country, working with their chapters to introduce students and the public to the profession.  The ASLA Green Roof page is pretty awesome, containing:  Green Roof Central, Tour the Green Roof, Green Roof Data, Contributors and Benefactors, and a Student/Teacher Guide – plus some great photos, graphics, and videos.

Held on, the 15th Annual Webby Awards say “Help create the Web by You” and be a part of the experience  by voting for whom we think deserves to take home a People’s Voice Award.

“Unlike other award shows that crown just one winner chosen by the people, we think the public should have a say in who wins big. That’s why we give you the chance to crown a Webby winner in every category.

The Webby People’s Voice Awards honors the year’s best work in Websites, Interactive Advertising, Online Film & Video and Mobile. And while our esteemed judges have their own opinion, we want to hear from you. You can vote in every category, so go ahead. Step up on your soapbox and let the web know who rules your digital world.” ~  Webby Awards

The ASLA Green Roof page is  honored for their excellence in informing the public about their own greenroof at the ASLA Headquarters plus educating about living roofs in general.

Voting for the 2011 Webbys is open from April 12th through to April 28th 2011.  Jim says:

“I’m fairly certain that it’s the only nominee in the history of the Webbys that is focused on green roofs.” ~  Jim Lapides

So get going to have your say on who should win, including supporting  the “ASLA Green Roof Experience” – vote for them at the 2011 Webby Awards!  I just did.

You’ll need to create a quick profile and then you’re set.  They’re in second place right now – let’s get them to #1, which would make for a truly celebratory Landscape Architecture Month as well as support our industry by highlighting greenroofs!

Happy Greening,

~ Linda V.
