The Cool Roofing Materials Database was created in 1998 and may not be current.
Energy-efficient roofing systems can reduce roof temperatures significantly during the summer, and thus reduce the energy requirements for air conditioning. The purpose of this Cool Roofing Materials Database is to assist with the selection of roofing materials which reflect, or otherwise reject, the sun's radiant energy, before it penetrates into the interior of the building.
This Database has been prepared by the Heat Island Project within Berkeley Laboratory's Energy Technologies Area, under the direction of Paul Berdahl (PHBerdahl@lbl.gov). We welcome any comments you may have; they will help us improve the database.
