In this paper, an improved method was produced by incorporating a new control behavior model which was developed with the results of survey on the usage of air conditioner and radiation calculation model which considered surrounding buildings shade. By applying the improved method, air conditioning method and energy consumption were evaluated with 3 cases (Case 1: no surrounding buildings, Case 2: check layout, Case 3: brick layout). Consequently, in comparison with Case 1, the total cooling energy consumption in the living room reduced by 11% in Case 2 and by 15% in Case 3, while the cross ventilation duration in the living room increased by 5% in Case 2 and by 6% in Case 3. It is suggested that in Case 2 and Case 3, the solar radiation absorbed by inner and outer walls was reduced by surrounding buildings shade, thus resulting in decrease of total cooling energy cosumption.
