Determination of energy reduction in retrofitted homes.

Presents the analysis of the effect of energy saving retrofits installed in low-income housing under a nationwide weatherization demonstration program. Weatherization techniques included caulking and weatherstripping, insulation and modification or replacement of heating systems. Two years of pre-retrofit fuel consumption data were analyzed to predict energy usage if the house had not been retrofitted. Energy reduction due to retrofitting was calculated from this. The average saving in fuel consumption for retrofitted dwellings was 30%.
