Abstract

The parameters which include Present Worth Factor, the wall structure, thermal conductivity of insulation material, thickness of insulation and the heating /cooling load of building, affect the energy savings in buildings. This study focuses on parametric analysis of the energy savings for building walls by using insulations (Expended Polystyrene and Glass wool). The annual energy requirements of house have been obtained by heating Degree-Days (DD) concept. For economic analysis, the Life Cost method has been used to determine optimum insulation thickness.
Day by day the energy consumption is gradually increased. But the amount of energy source is limited. So it is necessary to conserve the energy resources for future. In general the heat losses will occurs through Boundary walls, Roof, any opening like door opening or window opening and floor. But during the analysis of energy saving, only the outer boundary envelops is considered due to maximum amount of heat is transmitted through Boundary walls.
Results show that with an increase in Present worth Factor (PWF), energy saving increases. But energy saving decreases with increase in thermal conductivity of insulation materials. Initially, energy saving will increase with increase in insulation thickness, then it will be maximum and after that it will decrease with increase of insulation thickness. Maximum energy saving will occur at optimum thickness. It means that insulation should be provided on building wall at optimum thickness. Energy saving has higher value by using Expended Polystrene(EPS) insulation as compared to Glass wool.

Keywords: Insulation material, Life cycle method, Energy saving, Thermal conductivity, Present Worth Factor, Degree-Days
