摘要
The per capita energy usage in Saudi Arabia is almost three times higher than the global average. A major contributor is the residential sector which consumes almost 50% of the total national energy consumption every year. Environmental and economic pressures along with the Saudi Vision 2030 reform program advocate for an improvement in energy consumption patterns. For a sustainable residential sector, energy-efficient solutions should be adopted in the design process preferably based on building performance simulation (BPS). This study investigates the existing status and future prospects of BPS in the construction industry of Saudi Arabia. A survey has been carried out with building industry professionals to investigate the existing practices in terms of use of BPS. Energy and environmental savings achievable through application of BPS have been estimated by modelling a typical residential villa as a case study. The results indicate that presently BPS is not being adequately applied by the building industry and a number of barriers exist which need to be addressed. The case study simulation indicates that electricity consumption of a villa based on a BPS-based design process is 51.3% less than the existing typical residential villa.
