A Case Study on Application of Exterior Insulation Finishing System and Heat Reflective coating for Energy Efficient Building

B. M. Suman, Principal Technical Officer, Central Building Research Institute Roorkee, Uttarakhand (India)

The experimental study has been carried out in two rooms, identical in all respect. One room of the two identical rooms was white washed which is considered as reference room and other room was treated with Heat Reflective coating and EIFS. The Paper presents a case study on application of Heat Reflective coating (HRC) over Exterior Insulation Finishing System (EFIS) on wall and HRC on roof for energy conservation in a building. The experiment was conducted by using two Air-conditioners of 1.5 ton capacities in each of the identical rooms maintaining indoor temperature at 23oC. The result of the study shows that when all the four walls are treated with EIFS and HRC and roof is untreated it can save energy in comparison to the reference room by 20.51 %. The saving of energy may be enhanced up to 32.33% by treating the four walls with HRC over EIFS and the roof is coated with HRC.
