Description

This paper discusses the potential of DEA (Data Envelopment Analysis) for performance evaluation on domestic energy consumption. The purpose is to develop evaluation methodology for diversification of energy provision and consumption. From four evaluation measures (economy, environment, comfortability and risk), this paper focuses economical and environmental aspects, and selects energy consumption, CO2 discharge and cost as inputs for the first step model. In order to consider the evaluation methodology based on the practical data, this paper has focused on hot-water supply as output of the model. Then the numerical study for four monitor homes illustrates four kinds of findings. This paper also compares our DEA-based analysis with the traditional regression model based analysis, and implies the future research.
