Factory-built structural insulated panels are used for off-site building construction to minimize the labour needed for construction framing, which aims to save construction time and improve the quality of the installation. The panels, instead of using wood or steel framing, are the structural support for walls. Although the insulated panels provide structure, additional reinforcements are needed in order for the panels to be used on a multi-storey residential building.

Hot summers and cold winters present a significant challenge for affordable housing. Effective utilization of solar energy for thermal comfort provides an environmentally sustainable solution to reduce utility bills. The objective of this research project is to investigate alternative solar technologies that can be combined with a thermal energy storage system and air source heat pump to provide an energy efficient and cost-effective solution for affordable housing. The proposed thermal energy storage system will be contained within insulated expanded polypropylene (EPP) wall panel system.
