Abstract. In hot and arid climate such as the weather in Kerman , overheating in internal spaces in a building is crucial, especially in hot seasons. A large amount of heat gain is occurred though solar radiation and heat conduction. Most of heat gain is related to the size of window area. This paper investigated the correlation between the size of window area and amount of heat gain through solar radiation and heat conduction. This research was conducted through simulation program IES<VE>. Ten rooms with the same characteristics with different Window areas (from 10% WWR to 100%WWR) were modeled in simulation program. Then, the amount of heat gain through solar radiation and conduction was calculated for 22nd of June. Finally, the results were compared for different models. The findings of this research indicated that there is a direct correlation between window size and amount of heat gain.
