Electricity use for residential space heating: comparison of the Princeton Scorekeeping Method with end-use load data
The Princeton Scorekeeping Method (PRISM) is perhaps the best known and most widely used method to adjust residential use data for differences in winter severity. Purpose of this report is to compare PRISM results with submetered data from homes in Hood River, Oregon. The data used for this analysis are being collected as part of the Hood River Conservation Project (HRCP), a major residential retrofit demonstration project. HRCP data include whole-house and space-heating electricity uses, recorded at 15-minute intervals. Weather data are also recorded at 15-minute intervals, at the Hood River Experiment Station. The usual NOAA weather data were also available for this station; NOAA data on daily temperatures were used in this project. Finally, results of a detailed on-site home interview with these households are also available for analysis. We compared PRISM estimates of total annual electricity use and of space heating electricity use with annual aggregates of the load data. These comparisons were conducted with two sets of the Hood River submetered homes. The first set consisted of 185 homes that used more than 2000 kWh for space heating during the 1984/85 year. The second set, a subset of the first, included 71 homes that used more than 4000 kWh/year for space heating, did not have portable electric heaters, and did not extensively use their air conditioners.
