Environmental problems such as global warming become social issues today. It is reported that increasing energy consumption has affected on these environmental issues. Buildings deploys 40 percent of the raw materials in the world while at the same time they emit over 35 percent of the total CO2, so that it utilize over 50 percent of the whole energy in the world. At this point, energy saving though effective building control may eventually bring social, environmental and economical effects. Thus, this study will explore the difference between measured temperature and monitored temperature for operating air control system in the building, to which BEMS is applied. Also, it will suggest a method to accurately predict the load of air-conditioning, and will examine the different amounts of the load according to the temperature as well as the reduced amount of the load through changes of operation standard temperature.
