Just recently, Washington has dedicated a green roof demonstration project for the American Society of Landscape Architects (ASLA) located on the top of their headquarters building in the heart of D.C.'s Chinatown. Prior to the realization of the project, a Green Roof Task Force of ASLA members convened and discussed the role landscape architects will play with green roof technology as green roofs become more and more familiar to the urban fabric. The Task Force determined that the demonstration roof garden would need to demonstrate the likely market that landscape architects will be able to make significant contributions to and it lies something between a roof garden and an extensive green roof. The ASLA Green Roof Demonstration project was designed by Michael Van Valkenburgh Assoc. Inc. (MVVA) as the project lead, with Conservation Design Forum and DMJM Design providing supporting roles. American Hydrotech supplied the GardNet green roof system. The honeycomb-like product was laid on top of the drainage sheets and fabrics and then filled with growth media and plants. The completed roof is well on its way to leading Washington's charge to green roof construction.
