Abstract

The infiltration rate and thermal resistance of the building envelope has a significant effect on the energy consumption of buildings among the construction factors. Both of these factors are affected by the building envelope design and its details. The purpose of this paper is to find out how the interaction of these two factors simultaneously affects the building energy consumption. The case study of this research is the schools constructed based on the specifications and standards of the School Renovation Organization in the humid temperate climate of Iran. Due to the possible cross-impact of these two variables, the effect of these two is examined concurrently. Based on the results of this study in this climate, the infiltration rate of the building has a much greater influence than the thermal resistance of the building walls on the total energy consumption. Therefore, by reducing the building's leakage to minimum, the total energy consumption of the building can be reduced by 20%, And the process of reducing energy consumption as a result of increasing the thermal resistance of the walls is depended on the amount of Infiltration rate of the building.
