Insulation of Ceiling with Different Insulation Materials and its Effect on Energy Saving

Abstract

The aim of this paper is to investigate the effect of ceiling insulation with different insulation material on energy saving. The values of the optimum insulation thickness, the payback periods (PP), and the life-cycle savings (LCS) for three different types of insulation materials (expanded polystyrene, glass wool, and rock wool) were calculated. In calculations, life cycle cost analysis (LCCA) was applied. In the analysis, the present-worth factor (PWF) technique was used for evaluating systems and annual interest and inflation rates were taken 8% and 0%, respectively. The best solution was obtained when the expanded polystyrene was used. The optimum insulation thickness, PP, and LCS were computed as 0.0901m, 1.615years, and 9.643 $/m2, respectively.
