WASHINGTON, DC, April 5, 2006---The American Society of Landscape Architects (ASLA) has selected American Hydrotech, Inc., Emory Knoll Farms, Inc./Greenroofplants.com, ForestWorld, Green Roof Blocks/Saint Louis Metalworks Company, Ohio Gratings, Outdoor Illumination, and Dow Chemical Company to provide products and services for its green roof in downtown Washington, D.C.
American Hydrotech, Inc. will provide the green roof assembly, including the roofing membrane and insulation, and is also assisting with technical expertise. Emory Knoll Farms, Inc./ Greenroofplants.com will provide the green roof plantings, or sedum, for extensive portions of the roof, and assisted the landscape architects with the planting plan and testing. ForestWorld will provide FSC certified ipe wood, a sustainably forested wood product known for its durability in outdoor use, for the project’s decking. Green Roof Blocks/Saint Louis Metalworks Company has been selected to provide the green roof edging and drains.
Ohio Gratings will provide the aluminum grating for the walking surface on the roof, which will allow plants to grow beneath it, maximizing the planting area of the roof. Outdoor Illumination was selected to work with the landscape architects to design the lighting and will provide fixtures. Dow Chemical Company is providing the extruded polystyrene insulation.
“ASLA selected these product suppliers because of their experience in working with green roof projects and their enthusiasm for promoting this sustainable building technology in the United States,” said Nancy Somerville, executive vice president and CEO of ASLA. “Our landscape architects have worked closely with them to develop innovative and cost-effective uses for their products to showcase the versatility of green roof design. These suppliers have been very generous in sharing their experience and technical expertise with our design and construction team, and we are indeed fortunate to have them partner with us on this project.”
The ASLA green roof will serve as a demonstration project, showcasing the environmental and aesthetic value of green roofs. The project is scheduled for dedication on April 26, 2006.
