ASSESSING THE IMPACT OF PASSIVE COOLING ON THERMAL COMFORT IN LIG HOUSE USING CFD

Abstract

It has been observed that existing low income group (LIG) houses are inefficient to provide thermal comfort in Raipur, Chhattisgarh. This makes more dependency on cooling equipment to achieve thermal comfort which leads to more energy consumption. The objective of the present work is to investigate and enhance the thermal comfort of LIG house by passive cooling techniques. Different cases considered in the present study are, the effect of windows, green roof and green walls and shaded wall etc. on the indoor temperature of LIG house on May 20, 2016. Results concluded that at summer during the early morning, when the outside temperature is lower than the inside temperature, it reduces the room temperature but insufficient to provide thermal comfort. It is also concluded that providing green roof along with green walls enhance the indoor temperature of the house.
