THERMAL PERFORMANCE OF AN INSULATED AND WINDOW AREA OPTIMIZED HOUSE
Abstract
Space heating and cooling inside the building consume a lot of energy. Energy efficient buildings can reduce this energy consumption. Thermal insulators reduce the heat flow into and out of the buildings. Providing air gap and optimizing window area also reduce the cooling load. Present work is the comparison of thermal performance of an uninsulated and an insulated & window area of a house occupied during summer. The indoor air temperature is much lesser for summer season in case of house with insulation on inside and smaller window area as compared to an uninsulated house. The maximum indoor air temperature difference for insulated house as compared to uninsulated house is 5.73°C, 5.65°C, 2.96°C, 3.23°C and 3.08°C for the months from May to September respectively. There are energy savings for an insulated house as compared to an uninsulated house for the summer season. The total energy savings for the summer season are 4514 units. There are money savings also for the insulated house for the summer season. The total money savings for the summer season are Rs. 22574. The carbon dioxide (CO2) emission is also reduced for the insulated house for each month of the summer season. Total reduction in carbon dioxide emission for the summer season is 7078 kg. The thermal performance of an insulated and window area optimized house is better than an uninsulated house. In addition to the better human comfort the insulated house also offers money and energy savings. Also the insulated house is environment friendly.
