This paper develops a benchmarking process for energy efficiency for cooling purposes by means of data envelopment analysis and cooling degree hour method. The research begins by using climate data to calculate cooling degree hour and proceeds to build an index of total performance of energy for cooling purposes by linear regression method using energy consumption of building as dependent variable and cooling degree hour as independent variable. Finally, using data envelopment analysis, this study benchmarks the energy efficiency for cooling purposes in buildings with the index of total performance of energy for cooling by removing the effect of building scale factors, such as floor area and number of occupants. An application to office buildings in Taiwan is presented to illustrate the development and the use of the evaluating method.
