BECA-B assesses the technical performance and economics of energy conservation retrofit measures in houses. The data collected thus far represent measured energy savings and retrofit costs for over 65 North American residential retrofit projects. The sample size within each project ranges from individual homes to 33,000 dwellings participating in a utility-sponsored program. The median value of energy savings is 22%. For fuel-heated homes, the median cost of conserved energy is $3.86/MBtu, substantially less than the average 1981 prices for purchased energy of $4.50/MBtu for natural gas and $8.70/MBtu for fuel oil. For ten of the eleven electric heat retrofits the cost of conserved electricity is less than the 1981 average residential electricity price of 6.2c/kWh.
