Abstract: Concrete is a major construction material which absorbs and emits heat from the Sun. To compensate this, more cooling load is required and window blinds. This draws more electricity which in turn depletes the natural resources on a greater scale. Our study is to balance between the lighting and cooling load by analyzing the effects of two different window to wall ratios through Designbuilder. A residential space in Chennai, Tamil Nadu, India is chosen for the study. All details (materials used, thermal transmittance of these materials, climatic condition including ambient temperature and number of summer days, orientation of structure and window to wall ratios, number of occupants, purpose of building etc.) regarding the structure and the temperature of the city is fed in and the analyses are run. The software gives us an idea on the thermal and lighting characteristics of the 3D model of the structure created in it. This can be viewed in both daily and monthly intervals. Also the analyses give us information on paramount parameters of conserving energy. We compare the results between the two window to wall ratios. With this we suggest ways which bring us far from exploiting fossil fuels thus conserving energy in the ways possible. The conclusion of this study is illustrated later section in this paper
