Windows optimization for office buildings in Islamabad Pakistan

Abstract

The office buildings are main consumers of energy for space cooling in Pakistan. In this study a three storied office building was selected for studying the energy consumption. The data was collected from the se- lected building and was entered to eQuest software proram for simulation. This model was termed as baseline model. The building was further optimized with the windows area and glazing type separately. The results were compared with the baseline model. Simulation results showed that 10.5% of electrical energy used for cooling purposes can be saved by reducing the windows area. And up to 5% of the energy can be saved by using the double glazed brown tinted windows instead of single glazed windows.
