Energy balance of a medium residential apartment in Tehran is assessed comparing to average household energy consumption in the Netherlands. Both experimental and statistical methods are used and compared. Result implies that the residential sector in Iran uses 15% more primary energy than the same in the Netherlands. Considering this fact that Tehran experiences 37% lower cold days (degree-days indicator) than Netherlands’ average, this difference even could reach more than 50%. In fact the necessity of a precise built environment energy management i.e. building insulation strategies seems to be a serious factor of this difference which should be improved.
