Prefabricated modular construction is one of building solutions that has positive effects on construction time and waste management. In general, thermal performance of the building envelope is an important parameter which dictates the operational energy consumption. There are some prefabricated modular buildings available in Australia. However, their thermal performance benchmarks have not been well documented in the literature. Innovative panel systems have been proposed to improve the cost competitiveness and to achieve better performance. It is essential to know the current performance so that newer panels can be proven to be better. This paper investigates the thermal performance of four prefabricated modular buildings currently available in the Australian market. The buildings were selected to represent single-family houses with different floor areas. A building energy performance simulation tool was used to predict the cooling and heating loads of each building. The findings based on the simulations are presented in this paper.
