American Society of Landscape Architects: New Green Roof is a Top Level Performer for ASLA
The American Society of Landscape Architects recently completed a year-long monitoring project of its green roof. The results found that the roof retained thousands of gallons of stormwater, reduced building energy costs by hundreds of dollars a month, and significantly lowered outdoor air temperature.
From July 2006 to May 2007, the roof prevented 27,500 gallons of stormwater – nearly 75% of all precipitation on the roof – from flowing into
The roof also reduced the building’s energy costs –especially in the winter. Engineering analysis showed that the green roof’s extra insulation lowered energy usage in the winter by 10 percent with a potential of two to three percent in the summer.
