Video & Project of the Week for November 17, 2014: Hilton Garden Inn – West End

November 19, 2014 at 1:19 pm Project of the Week: 11/17/14


Hilton Garden Inn – West End
Washington, DC, USA

5,820 sf. Greenroof


Project Description & Details

Pursuing LEED Silver, the four-star 167,888 square foot Hilton Garden Inn West End hotel is an upscale mid-priced 238-room hotel situated within walking distance of Washington, D.C.’s most iconic attractions and corporations. Upon opening in May 2014, the Hilton Garden Inn began participating in the LightStay program, a Hilton Worldwide initiative to save energy by continuous measurement and reduction of electric, gas and water consumption. Contributing to the LEED accreditation, this property designed by Shalom Baranes Associates includes condensate recovery, ventilation recovery, low VOC finishes and seven separate vegetative roofs over three different roof levels.

Prospect Waterproofing installed the second level courtyard greenroof system by American Hydrotech with over thirty different varieties of perennials and deciduous shrubs in engineered growing media ranging in depths of 8″ to 16″. Triangular pyramidal skylights lend a modern feel to this outdoor space, while a perimeter green screen with trellising vines add additional urban greenification. Vegetation at the pool deck and penthouse roof levels consists of deciduous perennials intermixed with sedum and other succulents. Tall grasses installed near the building rising wall adjacent to the pool area offer contrasting vegetation heights. Below surface drip irrigation was installed and in lieu of standard irrigation timers, soil moisture sensors mitigate any unnecessary watering. Craning in a difficult and high-traffic area of DC made logistical coordination essential. Construction required coordination with multiple trades including masons, electricians, steelworkers and plumbers.

Video & Project of the Week for June 30, 2014: American Psychological Association (APA) Headquarters

July 3, 2014 at 11:03 am Project of the Week: 6/30/14


American Psychological Association (APA) Headquarters
Washington, DC, USA
2,500 sf Greenroof


Project Description & Details

The American Psychological Association (APA) is the largest scientific and professional organization representing psychology in the United States. In an effort to reduce energy consumption, maximize recycling and contribute to a healthier environment, in April 2014 a second greenroof was added to APA properties at their headquarters (see the APA/World Resources Institute HQ from 2008), which qualified for the DDOE grant program. In 2012, the Environmental Protection Agency rated both buildings in the top 10 percent of buildings in the U.S. with the lowest carbon footprint.

The design at the APA HQ building was focused on how greenroofs benefit people’s mental well being. Rebate funding was provided by the District Department of the Environment through a program  administered by the Anacostia Watershed Society; many private companies were also involved which made this project successful. Installed by Capitol Greenroofs, the system design called for plenty of seating and relaxation with Bison Innovative Products decking tiles, metal planters, and perennial planting areas. Composed of a mixture of perennials, woody shrubs and small magnolia trees set within modern style seating areas with bright decorative accents, this greened patio creates usable event space with spectacular views of the Capitol building.

Greenroof Project of the Week for November 18, 2013: International Monetary Fund (IMF) HQ #2

November 21, 2013 at 2:34 pm Project of the Week: 11/18/13


International Monetary Fund (IMF) HQ #2
Washington, DC, USA
28,374 sq. ft Greenroof


Project Description & Details

The International Monetary Fund (IMF), also known as the world’s bank, headquartered in Washington, D.C., has two buildings across the street from one another, Headquarters 1 and Headquarters 2. In 2009, IMF’s Headquarters #2 became LEED Gold certified, and in 2013 HQ2 achieved LEED Platinum Existing Building: Operations and Maintenance. Employing new Barrett Ram Tough 250 rubberized asphalt, Barrett Company provided a 20 year Vegetative Roofing System warranty for both greenroof projects.

At the HQ2 Building, although the green roof itself is inaccessible, employees and visitors may enjoy the scenic overlook from a patio area with tables and chairs. The existing roofing system was a hot applied rubberized asphalt membrane installed just a few years ago, but realizing the strong need for greenroofs in the Capitol District, the IMF decided to convert the existing ballasted assembly to a greenroofing system. The new and old membrane system was covered with a 4 inch deep extensive green roofing system with 5 species of sedum using pre-vegetated sedum mats from Moerings Sempergreen.


The International Monetary Fund HQ #2 is featured in the month of December in The 2014 Greenroofs & Walls of the World™ Calendar – order yours today. They make a perfect holiday gift for your family, friends, staff and clients!

– Hello, I’m Anjuli Velázquez and welcome to “This Week in Review” for September 28th, 2012 on GreenroofsTV.

Project of the Week

-Our project of the week is the New York PS41 Greenroof Environmental Literacy Laboratory (GELL), built in 2012 in Greenwich Village, New York, NY. PS41 is a K-5 grammar school that serves about 800 students at the heart of one of New York City’s high-density neighborhoods with little open space. After six years of planning, fundraising, building evaluation and construction, the Greenroof Environmental Literacy Laboratory at PS41 is open. The goal is to create a learning laboratory that raises environmental literacy and enhances students’ awareness of the stewardship role they play in the health of the planet.

The school’s 9,000 sf greenroof includes a central outdoor classroom area and is the centerpiece of GELL. Installed in August 2012, it uses the LiveRoof® Hybrid Green Roof System. Manhattan Borough President Scott M. Stringer said, “The opening of the Greenroof Environmental Literacy Laboratory at PS41 is a landmark event, not just because it is the largest such roof at a New York City public school – but because it expands our commitment to making environmental study a fixture in classrooms.”

In the News

– reports on “PSU students install green roof on campus.”  Students of Portland State University spent their weekend installing their own greenroof.  About 30 students helped put together the 3,000-square-foot greenroof and install the plants onto the roof of the Cramer Hall.

Project Manager Austin Hudson said, “This allows us to more effectively assess how the native and non-native plants are compared against each other.”  The students of civil and environmental engineering classes will now have a living laboratory and a great learning experience that can last for years.

-Douglas Canter of talks about “Mayor Vincent Gray makes DC Department of Environment headquarters greener.”  Washington, DC Mayor Vincent Gray is making the Department of Environment’s headquarters more environmentally-friendly by adding two new recently completed rain gardens.  The ground outside of the HQ slopes down toward a pebble-covered swale, filled with wetland plants, flowering perennials, grasses and blueberry bushes.

Also part of the Mayor’s effort, the Department installed a 10,500 square foot greenroof last year and hopes to install solar panels by the end of this year. Greenroofs and rain gardens act as Earth’s filtration and will help reduce pollution that would otherwise flow into the Potomac and Anacostia Rivers, Rock Creek and eventually the Chesapeake Bay.
