A field test was performed in Buffalo, New York, to evaluate the performance of an energy-efficiency measure selection technique for single-family houses. The design of this field test was based on a monitoring protocol developed for research projects sponsored by the US Department of Energy. The monitoring performed in following this protocol and the improved understanding of conservation measures obtained through analysis of the specified data are presented. Normalisation of measured space heating energy consumption using indoor as well as outdoor temperature improved the quality of the final results because the basis for comparisons was improved and sources of variability were reduced. Space heating energy savings were 252 therms/year (26.6 GJ/year), which is 25% of pre-weatherisation space heating energy consumption and 85% of predicted savings.
