Quantifying Energy Savings from Implementation of Energy Conservation Measures (ECMs) in a Residential Building: A Case Study of a Double Storey Bungalow in Malaysia
Energy efficiency and conservation has been gaining much attention in recent years, and is strongly encouraged by the government as well as the energy sector as it is a vital step towards a sustainable global energy ecosystem. However, the identification of the cause of energy wastage and inefficiency in residential buildings is rather challenging. Several studies related to the prediction of energy saving through the implementation of Energy Conservation Measures (ECMs) have been conducted over the years. However, the majority of these studies are based on commercial and public buildings such as offices, educational institutions and government buildings.The constraint of performing the energy audit for residential buildings can be solved using softwares. In this study, Building Energy Intensity Tool (BEIT) is used to perform the energy simulation on a double-storey bungalow to determine the potential energy savings as a result of implementation of ECMs. The study suggests several improvements that can reduce the overall energy consumption in the building. Results show that significant energy savings can be achieved by installing tinted films for the windows in the building as well as roof insulation. A simple change in the occupants’ behaviour such as reducing the lighting and plug load also brings about significant energy savings. The implementation of ECMs in the residential building is economically viable since the payback period is reasonable.
