A Houston-based landscaping company installed the first extensive “green” grass roof on a commercial office building in Webster. The roof is covered with eight inches of lightweight soil and drought-tolerant grass that does not need mowing.
The grass helps insulate the rooftop, saving electricity and reducing heat generated by the building. Improvements in building energy codes called for by the Federal Energy Policy Act of 2005 could save $55 million nationwide by 2010.
