Green Revolution: Green Roofs

A green roof can certainly make a building look nicer, but can it measurable lower energyrequirements and improve water management? Engineer Jelena Srebric and horticulturist Rob Berghage are working on a project to measure and model how a green roof affects the way buildings use energy and water. In the lab, Tyler Meek does weather experiments indoors to determine the effects of light, wind and water on the roof. Paulo Tabares Velasco works to make a mathematical model to predict what will happen in the real world. The researchers hope that architects will someday use their model to make building designs even greener.
