Green Roofs, 1 CEU APLD, 1 CEU LA CES, 1 CEU LEED

Presented by: Tom Hawkins, Florasource Ltd.
Friday, March 30th - 1:30 - 2:30 PM

Course Description:

Green roofs offer a relatively low tech, but well-proven approach to energy conservation, significantly impacting temperatures in local environments (urban heat island effect) and within building structures. A typical extensive green roof system (four inches of soil depth plus plant cover) can reduce air-conditioning costs by 25 to 50 percent in a single story structure. By cooling roof top temperatures on multiple story structures, green roofs can as well increase the efficiencies of the air conditioning systems, allowing for smaller units and thereby reducing energy costs.

This session will provide an overview energy conservation studies on green roofs and will highlight some green roof installations within our state. Discussion will also include some of the cost-benefits of greening rooftops in California's unique climate.
