In applying BEMS, it is necessary to perform economic evaluation about suggested BEMS technology and have it reflected in decision making process. The purpose of this study is to perform energy audit for a 14-year-old office building, to suggest the most appropriate BEMS technology for energy savings and to conduct economic analysis of BEMS via different levels of application. BEMS technologies intended to increase energy efficiency and operation performance of buildings presented in this study are suggested and typically it is expected that potential saving rate can be rendered up to 37.8%. As a result of economic analysis on about 20 BEMS applications, there were 15 cases where payback period was 5 years or less and on average, it was 0.67 year. And, to justify the extra cost, having taken the following items into account; savings, investment cost by measurement level, maximum establishment alternative, minimum establishment alternative and intermediate establishment alternative, payback periods were calculated to be at 8.04, 6.05, and 6.31 years, respectively, which are the results taking over 5 year payback period. And, the validity evaluation process in case of BEMS application is proposed.
