The aim of this study was to determine the appropriate direction of buildings in Qir town in relation tothe sun radiation. The geographical locationofthe examined town has led to the dominance of a dry and hot climate in most of the year. Therefore in making the direction of the buildings, protecting the buildings against sun radiation in hot days is in the first priority, and maximum use of sun radiation in cold days is in the next priority. In order to realize the mentioned goals, at first the amount of solar energy radiated onvertical surfaces of the buildings was calculated theoretically and practically by computational method of cosine law. Then using the calendar table of need to shade and sunshine,and effective temperaturecalculation chart, hot and cold times of year were determined, then using the tables obtained, the determination of the best appropriate direction of the buildings of the examined town was done. Themost ideal direction determined for single-sided buildings was +150 to +165, and +165 and -15 fordouble-sided buildings, and 180 was selectedas the acceptable direction.
