Title: Effect of a radiant barrier on the cooling load of a residential application in a hot and arid region: Attic duct effect

Abstract

A computer simulation showed that an attic radiant barrier system (RBS) (a commercial product laminated to the underside of the roof sheathing) significantly reduces cooling load requirements in hot desert climates. This reduction was due to both a reduction in sensible heat transfer through the ceiling and an even greater reduction in losses (heat pickup) by the HVAC ducting system in the attic. These reductions were around 16% in runtime over the daytime hours and an overall 9% reduction over a five-day period. This latter effect indicates the need to improve current duct-loss calculation methods.
