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

Summary

A computer simulation showed that an attic radiant barrier system 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 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.
