The effect of materials in reducing energy consumption in atrium commercial centers in the north and center of Tehran province

Abstract

Atriums in shopping malls as a passive solar system can reduce the consumption of lighting and artificial ventilation systems in addition to providing light. But at present, due to the lack of suitable materials or lack of climatic information with the required formats of energy simulation software, all research conducted in different cities of Tehran province has been done only with meteorological data of Mehrabad airport, which has sometimes led to erroneous results. This study was conducted to study the effect of materials in reducing energy consumption in commercial centers in the north and center of Tehran province using DesignBuilder software and has taken steps to solve this problem by modifying climate information in the study area. The general method of this research is simulation with a case study approach and in terms of application type. The results of this study show that despite previous research by researchers who had previously expected that increasing the thermal resistance of materials always reduces energy consumption in buildings, but this study shows that in atrium commercial centers (chain stores) in the north and center of Tehran, in The correction of meteorological data in the micro-climate of the study area and due to the heating resulting from the internal equipment of chain stores, leads to completely different results from previous research. Thus, increasing the thermal resistance of materials in the northern climate of Tehran province reduces energy consumption by (24.7%) and vice versa in the central Tehran climate increases energy consumption by (13.7%).
