In this study, various energy conservation techniques and clean energy utilization prospects are investigated for the residential buildings of Saudi Arabia. A base case study of a distinctive residential building in Saudi Arabia is performed using simulation packages and its energy performance is optimized by incorporating the design standards of International Energy Conservation Code (IECC). The optimized results show that the energy consumed by the IECC standardized building is less by 56% for space cooling, 37% for space heating, 46% for lighting, and 27% for appliances. The IECC standardized building is integrated with a passive solar water heating system and a grid-connected solar PV system to meet the water heating load and lighting load, respectively. The use of solar water heating system shows 76% reduction in energy consumption as compared to the electric water heater. The feasibility of integrating a grid-connected solar PV system in the residential buildings is justified in terms of subsidy provided by the government and eco-environmental benefits. Finally, the prospects of utilizing solar energy in buildings are discussed with their economic and environmental benefits.

在这项研究中，研究了沙特阿拉伯居民住宅的各种节能技术和清洁能源利用前景。使用模拟程序包对沙特阿拉伯特色住宅建筑进行了基础案例研究，并通过纳入国际节能法（IECC）的设计标准来优化其能源性能。优化结果表明，IECC标准化建筑的能耗在空间制冷方面减少了56％，在空间供暖方面减少了37％，在照明方面减少了46％，在电器方面减少了27％。IECC标准化建筑与被动式太阳能热水系统和并网式太阳能PV系统集成在一起，分别满足了热水负荷和照明负荷。与电热水器相比，使用太阳能热水系统的能耗降低了76％。就政府提供的补贴和生态环境效益而言，将并网太阳能光伏系统集成到住宅建筑中的可行性是合理的。最后，讨论了在建筑中利用太阳能的前景及其经济和环境效益。
