Abstract
Recently the reduction of the CO2 exhaust is a worldwide problem. It is important to manage the supply and consumption of energy well. In this study, the method applies to the energy conservation and the natural energy such as solar was examined in our university. About crude petroleum, the energy conservation is possible about 60% to replace the air-conditioning machine. About electric power, the energy conservation is possible to reduce the standby electric power and to apply the solar cell generation. Some problems have been left such as leveling of electric consumption and efficient use of electric power when the solar cell generation is applied.
