ABSTRACT

 

The performance of a non air-conditioned building has been analyzed for cold climatic regions of India by using various thicknesses of insulation at different positions of the walls and roof i.e. on the external surface and the inner surface of the walls and in the middle of the walls. Single zone isolated building, having dimensions of 4m x 4m x 3m, and with south facing window 2 m x 1.6 m size, has been analyzed in this study. The periodic solution of the heat conduction equation describing the heat transmission through the different building components, floor, walls and roof has been adopted. Ambient temperature and total solar radiation intercepted by the building envelope have been represented through Fourier series. Traditional construction with 220 mm Burnt Clay Brick (BCB) wall, plastered 15 mm on both side without insulation and with insulation at different positions like internal and external surface of walls and in between the walls have been analyzed. It has been observed that thermal comfort for the three stations considered in this study can not be ensured in the month of January if the building is traditional (non- insulated).
