Abstract

Side-by-side tests were conducted in Cape Canaveral, FL to compare the cooling and heating energy use and electric peak demand requirements for two industrialized (Dow and Dome) and one conventional room-sized prototypes. The industrialized prototypes saved 11% to 16% in cooling energy and 45% to 56% in heating energy. The industrialized prototypes peak demand savings was 16% to 23% for cooling and 39% to 42% for heating. The energy performance of the Dome prototype was slightly better than that of the Dow. These results were as expected and are largely due to the higher insulation levels and greater air tightness of the industrialized prototypes. Data are also presented on summertime shingle temperatures on dark roofs over vented attics and over volume ceilings with no attic spaces. It was found that shingle temperatures over vented roofs ran 10 to 15°F cooler during peak summer conditions.In search of a more energy efficient roofing material to cover roofs without attics, tests were conducted on roofing tiles. Side-by-side tests on several scale model roofs were conducted to determine the most cost-effective roof tile configuration. This was then retrofitted on to the Dow prototype. As a result, its cooling performance improved measurably and became similar to that of the Dome prototype.
