Analysis of Daylighting in Educational Building of Composite Climate

Dr. Himanshu Poptani, Rifat Parveen

Abstract: Daylight is a resource for natural space-illumination. It is highly desirable to provide more usable daylight in buildings, not only for energy efficiency but also to increase the performance and well-being of the inhabitants. Daylight through the window is a popular solution for lighting indoor space. Using daylighting in educational buildings has many advantages and increases building?s and occupant?s efficiency. The application of daylighting strategies can minimize electrical energy for lighting and maintain a well-lit atmosphere in the educational building. Autodesk Ecotect 2011 is used to evaluate the daylight-related performance of illuminance and daylight factor. It is used for the simulation of design models to obtain daylight factor information and distribution of illuminance. Daylight factor and illuminance distribution are evaluated according to various room scenarios and different window configurations. Simulation studies conducted in this paper show that the openings in different orientations, windows with and without shading devices, the color of interior walls have different impacts on the daylight distribution inside the room in composite climate.
