Abstract: This study is to enhance and to ensure the thermal comfort inside a building (i.e. room temperature 20 2C) by using variable glazing area on south wall of the building for two different kinds of climatic zones i.e. cold-sunny (Leh, -14C to -2.8C) and cold-cloudy (Shimla, 1.9C to 8.5C, Shillong, 3.6C to 15.5C and Ootacamund, 5.1C to 19.9C). In this study, single zone isolated house, having dimension 4m 4m 3m, has been analyzed. The periodic solution of the heat conduction equation describing heat transmission through the different building components, floor, walls and roof has been adopted. Ambient temperature and total solar radiation received by the building envelope have been represented through Fourier series. Traditional construction with 220 mm Burnt Clay Brick wall (BCB), plastered 15 mm on both sides and the other construction of same dimensions, but insulated with 10 cm of expanded polystyrene insulation on four walls and roof have been analyzed. It is found that for the four stations considered, the traditional building is not able to ensure thermal comfort with different glazing areas. To enhance the indoor temperature for thermal comfort for an insulated building, different glazing areas are required for different stations under consideration. It has been observed that for insulated building, 10%, 15%, 20% and 40% glazed area is required for Ootacamund, Shillong, Shimla and Leh respectively.
