The Impact of Passive Strategies on the Overall Energy Performance of Traditional Houses in the Kingdom of Saudi Arabia

Communities in nations all over the world must work to address the problem of energy consumption, which has emerged in modern times. Given that domestic consumers account for roughly 49% of the total electricity used annually by all sectors, buildings can be seen as a key player in this conundrum. The architecture field can therefore play a vital role in saving energy, not only through building design but also through the materials used. To minimize architectural programmes’ negative impact on the environment, sustainable design that saves energy is being employed today in traditional Saudi Arabian buildings. This study examined whether current housing designs can effectively integrate four key passive energy-saving strategies: outdoor green area, thermal mass wall, window-to-wall ratio and shading device. This study analysed two types of traditional houses from two different cities in Saudi Arabia’s Najd region, Riyadh and Hail, examining the four passive strategies. Using traditional house designs, this paper created four simulation models for each house, and compared the simulation results with the base case model to determine how well these strategies could affect the energy consumption for residential buildings in Saudi Arabia (KSA). The results indicate that the selected strategies can play an important role in saving energy in residential buildings in the KSA.
