Energy conservation in public housing: A case study of the San Francisco housing authority
Abstract In 1982, the San Francisco Housing Authority began trying to reduce rapidly increasing energy expenses by installing attic insulation, exterior door weather stripping, low-flow shower-heads, and water-heater blankets in the buildings that it manages. The conservation measures were financed by the local utility's zero-interest loan program (ZIP). We analyze utility billing data for three years, including one post-retrofit year, at five multifamily housing projects (totalling 1822 units). Weather-normalized annual natural gas consumption declined by 13% after the retrofit at the five projects; net savings relative to a comparison group were8%. We determined that most of the energy savings resulted from reduced base level usage. We found that the retrofit program was cost-effective, with a net present value of $399 000 or $220/unit. The Housing Authority's careful efforts to control retrofit costs, which averaged only $150/unit, contributed to the program's success.
