Application of statistical Taguchi method to optimize main elements in the residential buildings in Malaysia based energy consumption

Abstract

Energy consumption is one of the controversial issues in the world. Rapid growing world energy consumption has already increased concern about the supply problems, heavy environmental effects such as climate change. One of the most users of energy is residential buildings that consume the biggest share of energy. Growth in population, rising demand for buildings together cause the upward trend in energy consumption. Therefore, energy efficiency in buildings plays a significant role to decrease the environmental effect. The goal of this paper is optimizing the main elements which are window, ceiling, and wall by considering the effect of uncontrollable factors such as humidity, temperature, and air flow in residential buildings using statistical method, namely Taguchi method. A two-storey house in Malaysia was selected to simulate by means of Building Information Modeling (BIM) application. Based on the result, the optimum energy saving will be achieved when the type of material which are used for wall, ceiling, and window are Brick Plaster, Acoustic Tile Suspended, and Single Glazed Alum Frame, respectively.
