Thermal and Energy Performance of Pitch and Wall Insulation for Air-Conditioned Buildings in Malaysia

Thermal design of building envelope and microclimatic conditions influence the indoor thermal comfort conditions and energy consumption of buildings. This paper presents the findings of study conducted to investigate the effect of building insulation on thermal impact and energy for cooling. The study were performed via computer simulation using a whole-building thermal energy software Integrated Environmental Solution (IES) with ApacheSim 5.9.2. The results show that pitch insulation (PITCH) was more effective to reduce the attic temperature but both pitch and wall insulation (WALL) had nominal thermal improvement for the indoor. However, compared to the BASE model, WALL model gave a significant savings of 41% for cooling
