Abstract：The authors investigated the energy efficient performances of public buildings in Hainan by a detailed survey on the building type, the date to build, the window to wal ratio, the constructions of wal, window and roof, and used DeST-h software to diagnosis and analyzed their potentials on energy efficient retrofit. The results show that the thermal performances of the envelopes were poor and the energy consumptions were high for. The key points of the energy efficiency retrofit are to decrease the overal shading coefficient of window and decrease the solar radiation absorptance of the roof and wall surfaces. After retrofitting, the energy saving is estimated to be 4.28%~5.71% for the office buildings and 1.38%~15.21% for the hotels while compared with the reference buildings.
