There are few end-use studies that report monitored space cooling energy consumption for residential buildings in hot-humid climates. This paper reports data from 25 occupied single-family houses in Palm Beach County, Florida (Messenger 1982). The houses were first monitored for one year in 1981 to establish their space cooling consumption. After the first year of monitoring they received a battery of retrofits predicted to reduce household energy use. Incorporated measures included conversion to high-efficiency air conditioners or heat pumps, added ceiling insulation, window films, awnings, zoned conditioning systems and ceiling fans. The houses were then monitored for an additional year to determine the relative savings achieved by the installed energy conservation measures.

This paper focuses on the analysis of data taken in the study with particular emphasis on the variation of space cooling energy use and how the retrofit treatments affected energy consumption in the monitored buildings. Although data on energy consumption was recorded on a monthly basis, all of the comparisons made in this paper are based on total seasonal energy consumption.
