Case Study on Building Orientation

Built environment is a manifestation of the technological innovation. The way technologies are applied in design and construction of buildings, have direct implications on the amount of energy consumed. In modern context buildings represent enclosed, isolated boxes/systems where environment is artificially controlled. This requires considerable energy. With the increased awareness of energy consumption as well as the environmental impact of building operations, architects, designers and planners are required to place more consideration on sustainability and energy performance of the building. To ensure most of those considerations are reflected in the building performance, critical design decisions should be made. Buildings consume large amounts of the electricity that is generated around the world and that artificial lighting and air-conditioning consume a significant part of this energy. Furthermore, generating such electricity leads to the production of greenhouse gases. An important factor in passive architecture Building Orientation that can lead to savings is the amount of daylight supplied to a space as this can reduce both the artificial lighting and air-conditioning load at the same time. Our work assesses the energy savings and reducing direct solar gain by assigning proper orientation to the building from which daylight and artificial lighting are properly integrated. Such an assessment comprises firstly study of orientation that can be applied in different climatic conditions and to various buildings as per requirement. The calculation of Direct solar gain that can be obtained through this analysis identifies whether the building is properly oriented or not.
