Pro Bono work on the Green Roof at the ASLA National Headquarters: Outdoor Illumination designed the outdoor lighting for the green roof on the headquarters building of the American Society of Landscape Architects (ASLA) in downtown Washington, D.C. Said Nancy Somerville, executive vice president and CEO of ASLA: “As an ASLA member and a leader in the landscape lighting field, Outdoor Illumination has been generous in sharing their experience and technical expertise with our design and construction team.” Our design created an outdoor room at night, employing indirect lighting via efficient halogen lamps. Aimed at creating comfort and safety for associates and guests, the perimeters were to be defined and the initial walk out was gently illuminated.
