Expanded Use for the Green Roof (A US Government Perspective)


The U.S. General Services Administration is the owner of an array of planted roofs on federal buildings.  This presentation will look at GSA’s inventory to pass on some of the key lessons learned for longevity, maintenance, and performance.  We will then delve into the benefits that GSA utilizes from planted roofs which is backed up by research, studies, and performance metrics.

We will explore how new legislation is expanding the use of plants and opening up our rooftops to a diverse habitat.  We will close out with a view of where we may be going in the very near future and how planted roofs can play a role in a vision of net 0.
