Abstract

In Iran, due to the low price of energy carriers, the amount of energy consumption in the country is high and it is considered one of the countries with very high energy consumption. The aim of this research is to investigate the amount of energy consumption in its optimization approach in a simulation room in Tehran, which is done by focusing on the type of openings and its dimensions and evaluated by Design builder software. The first stage of the simulation of the heating and cooling load of the simulated room was with 27 samples of opening combinations with glass, gas and different frames. The second stage is the evaluation of 4 opening modes with the size ratio of 1 to 1, 1 to 2, 2 to 1 and 2 to 2, which determines the best aspect ratio for the opening. Findings shows shows the comparison of the monthly average cooling load in the dimensions selected for four types of windows, shows that the highest cooling load is observed in type D and size 2.3, which is the largest opening size in the four options selected for evaluation, and naturally It leads to more cooling load. Types A and B, which indicate the dimensions of 1.5 x 2 and 1 x 2, show almost the same values in comparison of the average cooling load. Among these, the best result belongs to type C with dimensions of 2 x 2, which has the lowest amount of cooling load.
