Description
This paper reports on the first results from tests on a reflective roofing system on a commercial building in Florida. The building is a elementary school with a sloped, modified bitumen roof. Air-conditioning power was measured in a base configuration prior to the roofing system being changed to a white color. Roof, decking, and plenum air temperatures were strongly affected by the change to a white roof system. The school, which was monitored for a full year in both the pre- and post-condition, saw the measured annual chiller electric power reduced by 10%, or 13,000 kWh/yr. Cooling-load reductions during the utility summer peak were substantially greater, more than 30% during the afternoon hours.
