Research On Energy Efficiency And Energy Consumption Audit Of Public Buildings In Chongqing

Along with the rapid development of economy and the improvement of living standard, the energy consumption of buildings become the"bottle neck"of the increase of national economy and construction of harmonious society. Therefore, with the high density of energy consumption and rapidly developed speed, the public buildings lead the augment of power consumption rapidly. So there is no time to delay of public building energy consumption. In conclusions, it is very important to realize the actuality of energy consumption and analyze the characters of public building energy consumption. At last, we should find means and ways to cut energy consumption.The paper simulates the energy consumption of the business street by DeST. Secondly, choosing business strees as a simulating model for calculating air-conditioning load, determine simulation scheme by adopting orthogonal scheme methods, carry prominence analysis on factors which influence energy consumption of the dinging room.Base on the energy consumption analysis, some conservation measures can be done.①the effect of energy conservation of outside Sunshade and Low radiation window is notable, but the exterior wall isn't.②Reduce indoor comfort degree appropriately can realize considerable energy conservation effect.③It is obviously to energy conservation adopting changeable new wind with entire heat recovery.④It is suitable to intermittence running scheme for air-conditioning system in restaurants.⑤In transition season, it is significant to fully utilize natural cooling source (fresh air) in air-conditioning system for energy conservation.The paper summarizes energy consumption characteristic of public building and bring forward effective energy conservation approach. The paper is importance for promoting energy conservation work; it has very important theory and project applying value.
