Description:	Buildings in developed countries today consume a large portion of primary energy, which leads to more CO2 production and environmental pollution compared to other human enterprises or industries. Administrative buildings in universities consume large amounts of energy and materials, which can be comparable to that of small commercial cities. This study aims to provide feasible sustainable design guidelines and recommendations of retrofit strategies, which can be used to minimize office building energy consumption and building energy index (BEI). The Chancellery office building of University Kebangsaan Malaysia was chosen as the test bed for simulation studies. Integrated Environmental Solutions (IES) software was used to model the office building, as well as analyze thermal performance and cost benefits. Various types of energy efficient glazing such as single low-e glazing, double low-e glazing and triple glazing are discussed. Different types of thermal insulation materials are enumerated along with the selection criteria of these materials. In order to assess the performance of the selected passive design alternatives, life-cycle cost analysis was performed. It was found that by introducing optimal thicknesses of external wall insulation between 3. 5cm and by adding an air gap of 2cm, energy consumption cost was reduced to between 25 and 27.4 percent. The simulation results illustrated that application of advanced glazing would lead to a reduction in electricity consumption in the range of 5.1 to 8.14 percent. The life cycle saving due to application of single low-e, single low-e reverse glazing and double low-e glazing would be up to 3.14, 3.09, and 4.92 percent respectively. The simulation results suggest that for a medium rise office building in Malaysia, the use of double low-e glazing would not be economically viable. The Building Energy Index (BEI) for the base case study was 224 (kWh/m2/year). This study found that by applying passive design feature, considerable reduction of 10 percent can be achieved in energy whereas the Building Energy Index (BEI) can be reduced to 203 (kWh/m2/ year).,Master of Science
