Abstract

Abstract Buildings account for a significant amount of total energy consumption worldwide; and the use of fossil fuels in the short and long term will have serious and long-standing negative impacts on environment, including disruption to various ecosystems. Hence, it is vital to limit the growth of energy demand through energy efficiency in buildings. Double Skin Façade (DSF) technology is considered as one of the most advanced modes of direct passive systems for maximum use of solar energy to provide heat load and prevent heat loss in buildings. In general, the performance of DSF depends on climatic factors (such as solar radiation, air temperature, and wind speed) and various design parameters, including the effect of the gap between the outer and inner glass wall on the thermal behavior. Furthermore, the orientation of the building is one of the critical factors affecting the amount of energy consumed. Accordingly, the cooling rate, heating rate, and energy consumption at different angles are investigated by applying a numerical simulation. Due to the use of photovoltaics in the selected buildings, the amount of energy produced and consumed in different conditions has been inspected. Building energy modeling is also evaluated by rotating the building 90° at a time. The results show that more energy is produced in the south, west and east directions. The results show that the experimental design in this study saves 44% in energy consumption.
