Green Roof Sprouts Award
Green Roof Sprouts Award
The Green Roof Award of Excellence, in the category of extensive institutional roofing, was awarded to a living design. The winning roof design provides a long-term waterproofing solution, with a vegetative surface, for the Environmental Studies Building at Evergreen State College in Olympia, Washington.
The award was presented to Cleveland, Ohio-based Garland Company.
“Evergreen State College is an environmentally responsible campus committed to long-term sustainable design, says Brian Lambert, director of marketing for Garland. This project is evidence of that commitment, and a testimony to their vision.”
The project comprises 13 separate green roof areas totaling 24,000 square feet. The extensive green roofing uses Garland lightweight soil at depths from four to six inches. Its 33 distinct species of plants include low-growing ground covers, such as sedums, as well as a variety of perennial flowering plants. In keeping with the college’s environmentally responsible mission, all trees and shrubs that were cleared to construct the new Environmental Studies Building, were transplanted to other areas of the campus.
In addition to its energy-savings benefits, the Garland GreenShield vegetative roof system is helping the university to effectively manage stormwater run-off. The 24,000 square feet of green roofing has reduced the university’s retention-pond requirements. The waterproofing layer of the system is the Garland StressPly Plus multi-ply modified bitumen roofing membrane, which incorporates post-consumer and post-industrial recycled materials. The polyisocyanurate insulation used provides an R-value of 21. The system also includes recyclable stainless steel flashings.
LEED GOLD certification is currently pending for the college’s Environmental Studies Building. Architect for the new construction project was Mahlum Architects & Mark Cork & Brent Compton of Seattle, Washington. The roofing contractor was Wayne’s Roofing, and the landscaper was Northwest Landscape. DPR Construction, Inc. served as general contractor for the project. The Leadership in Energy and Environmental Design (LEED) Green Building Rating System is a voluntary, consensus-building national standard that was initiated by the U.S. Green Building Council (USGBC) for developing high-performance sustainable buildings.
