Saving energy and achieving effective energy saving solutions has become one of the most important issues in recent years. The importance of this issue can be understood in light of the worries and many recommendations for reducing it. Therefore, in this paper, a 4-storey office building in Tehran was simulated with the use of Design Builder software and the consumption of cooling and heating loads was calculated over a year. The three-chamber window was replaced by a double-chamber window and the addition of thermal insulation of 5 cm thick rock wool, heat transfer coefficient 730 and a density of 80 kg / m 3 on the wall to reduce energy consumption, and in particular, the efficiency of thermal insulation, Was studied. The main question is, to what extent are the exterior walls of the building effective in energy loss? The purpose of this study was to evaluate the external wall condition of a building in terms of thermal insulation efficiency in an office building in Tehran in winter and thus to evaluate the pre-construction energy loss and its application during the project implementation. This paper first investigates and captures the variables through the causal-experimental correlation research method and then observes its effects on the dependent variables.
