Abstract

With the increasing concern regarding the huge amounts of energy consumed and the repercussions on the world's environment, Malaysia is among the countries taking measures. Malaysia, a country that is rapidly growing in terms of economy, it has also dramatically increased energy consumption and demand, with roughly half of all electricity being used for commercial and non residential buildings in particular. This study presents a comprehensive analysis of cost saving and emission reduction of optimum thickness and air gaps for different insulation materials in building walls. Integrated Environmental Solution (IES) software was used to model the Chancellery office building at Universiti Kebangsaan Malaysia to analyze the thermal performance and its cost benefits. It was found that by introducing optimal thicknesses insulation between 3 and 5cm and by adding air gap of 2cm, energy consumption cost was reduced to 24 and 26% compared to a wall without insulation and air gap.
