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.
