Abstract：
Investigates and measures energy consumption, cold and heat source mode of air conditioning systems, thermal environment parameters, and thermal comfort sensation of occupants in fourteen different public buildings located in Changsha, Hunan Province. Finds that the mean energy consumption per unit building area is 1.71 GJ/(m2·a) and the mean air conditioning energy consumption per unit air conditioned area is 0.93 GJ/(m2·a). According to the problems found in the investigation, puts forward some approaches for improving energy utilization.
