For this purpose, a specific building with its architectural drawings was specified and heat loss equations were observed by using MS Excel according to TS 825. Calculations of heat loss were performed separately for four different types of heating zones in our country by selecting different cities in these zones. Bu using heat losses which were calculated based on placing the building in different zones, different types of heating strategies were determined. Moreover, fuel costs, installation cost and greenhouse gas emissions were determined based on different fuel usage ratios. These calculations and observed criteria were investigated by Analytical Hierarchy Process (AHP) and VIKOR, which are merged under Multi Criteria Decision Making Methods and an effort for showing the mathematical aspect of comparison of these selections was given in this study.}, number={2}, publisher={Parantez Teknoloji}
