Green Revolution: Green Roofs

6 minutes, 29 seconds

Now Playing As: Captioned (English) (Change)

A green roof can certainly make a building look nicer, but can it lower energy requirements 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. The researchers hope that architects will someday use their model to make building designs even greener. Part of the "Green Revolution" series.
