Abstract

At present, a large percentage of fossil fuel energy is consumed by the residential households globally for ongoing heating and cooling. With currently used house wall envelope, it is difficult to achieve higher energy efficiency as it has reached the limit. Therefore, the primary objective of this study is to study a new house wall envelope and its thermal energy performance for ongoing heating and cooling in two climate (arid and moderate) conditions. The study was undertaken using computer simulation. The results indicate that new house wall envelope made of new materials and modular systems provides better thermal performance and significant energy savings compared to the widely used brick veneer house wall envelope. The findings also show that the percentage of energy savings of new house wall envelope for the arid climate is much higher than that of the moderate climate.
