Energy demands have increased in the commercial sector, and building energy management has become an important issue for energy saving and environmenal protection, even in univeresity campuses. In this research, an energy management system is developed using BACnet - A Data Communication Protocol for Building Automation and Control Networks - as a standard communication protocol, to operate air conditioning units by gas engine heat pumps installed for classrooms and other rooms of a building in Osaka Prefecture University. Especially, a condition monitoring system is focused, and its graphical user interface is developed using X-Window to understand monitored data easily and flexibly. The condition monitoring is conducted and the monitored data is analyzed for the space heating mode in winter of 2009 fiscal year. Through the analysis, an energy saving potential is ascertained qualitatively in terms of unit operation times and set room temperatures.
