Field study of the effect of low-cost weatherstripping devices on energy use in single family (San Diego) residences.

Presents results obtained in field studies of control and test houses provided with low cost retrofit infiltration controls. There are significant estimates of average energy savings during both heating and cooling seasons. However, the 95% confidence intervals for the heating season span the origin and theprobability that savings were actually observed is less than 85% for the heating season. The probability that actual savings were measured during the cooling season is >95%. For installations made by homeowners, estimated average payback periods are well below 2 years and are therefore justified in terms of economic returns resulting from energy savings.
