Daylight Performance and Energy Consumption in a Simple Room of Residential Building in Dhaka City, Bangladesh

Daylight is the main contributor to save the energy consumption in the residential building because it is the most valuable natural resources available to architects and engineers to develop the visual quality of interior spaces. It is accredited that a significant reduction in artificial lighting and subsequent primary energy consumption can be achieved by maximizing the use of natural lighting (daylight). Therefore, strategies are needed for more daylight inclusion in the interiors of the residential building where electricity demand is very high. The main objectives of this study are to identify parameters of day lighting that can help to save energy consumption and to develop the daylight performances in a simple room in residential building in Dhaka city, Bangladesh. This study also helps the Bangladesh National Building Code (BNBC) to identify the minimum daylight parameters for a typical residential building which is constructed by local materials.
