Abstract

Electricity consumption data of four, all-electric apartment complexes were evaluated before and after conversion from master to individual meters. The effects of meter conversion were evaluated by an analysis of covariance. Of three degree-day statistics assessed for their adequacy as covariates, the sum of the absolute values of heat days and cool days was found to be best for this analysis. Results indicate significantly less electricity was consumed in the individual meter condition than in the master meter condition for all four complexes. Additional analyses suggest electricity consumption is less affected by temperature fluctuations in the individual meter condition than in the master meter condition.
