Residential energy conservation

Summarises information from energy audits and post installation inspections conducted as part of the Residential Weatherization Pilot Program, operated by the Bonneville Power Administration (BPA). The BPA offered free home energy audits to identify cost-effective conservation measures to reduce energy forspace and water heating, and zero-interest loans for retrofitting. More than 6000 homes were audited and 4000 loans made. Audit data suggest that annual electricity consumption can be cut by one third at a cost of 2000 dollars (1981 values). Infiltration reduction measures appear to be the most cost effective followed by insulation.
