The Impact of Orientation on Energy Use in Affordable Housing in Humid Tropical Climate Area

Abstract

One of the factors causing this increase is energy use in the housing sector. Based on reports from the BPS-Statistics Indonesia, there is still a shortage of 12.7 million houses. To meet this shortage, the Indonesian government provides subsidies for the provision of affordable housing as well as design standards for healthy affordable housing for low-income people. One option to optimize energy use in a residential home without incurring large additional costs is through the use of passive design. One of the determining factors in passive building design to reduce energy use is through determining the building orientation. This research will investigate the relationship between orientation and energy use in affordable housing in Indonesia. Through simulations carried out in conjunction with 24 orientations of healthy affordable housing in Indonesia, orientations that provide the best optimization value for energy use will be obtained. This research will only examine one parameter: building orientation. By knowing the optimal orientation and the energy that can be reduced through implementing this orientation, it is hoped that this research can be taken into consideration by the Indonesian government in making regulations regarding the orientation of healthy affordable housing in Indonesia.
