由于人口和经济增长，沙特阿拉伯王国（KSA）的电力消费每年增长约7%。住宅部门的消费量占总发电量的50%以上。此外，空调（AC）系统的能源消耗已成为夏季住宅建筑物总用电量的70%，导致电力需求达到高峰。本研究调查的解决方案，将解决与KSA的空调需求在住宅建筑物的高能源需求的问题。为了减少住宅领域的交流能源消耗，我们建议在恒温器设置中使用智能控制。智能控制可以通过（i）调度和提前控制AC系统的操作以及（ii）由公用事业适当地远程设置恒温器来利用。在这项研究中，我们模拟典型的住宅建筑，至关重要的是，占用行为的基础上，通过调查获得的行为数据。介绍了利雅得市住宅采用不同的交流运行模式对可实现节电的潜在影响。我们的计算机模拟结果表明，旨在有效降低能耗的解决方案，特别是在先进的操作模式下，导致年度总节能量增加30%至40%。
Electricity consumption in the Kingdom of Saudi Arabia (KSA) has grown at an annual rate of about 7% as a result of population and economic growth. The consumption of the residential sector accounts for over 50% of the total energy generation. Moreover, the energy consumption of air-conditioning (AC) systems has become 70% of residential buildings' total electricity consumption in the summer months, leading to a high peak electricity demand. This study investigates solutions that will tackle the problem of high energy demand associated with KSA's air-conditioning needs in residential buildings. To reduce the AC energy consumption in the residential sector, we propose the use of smart control in the thermostat settings. Smart control can be utilized by (i) scheduling and advance control of the operation of AC systems and (ii) remotely setting the thermostats appropriately by the utilities. In this study, we model typical residential buildings and, crucially, occupancy behavior based on behavioral data obtained through a survey. The potential impacts in terms of achievable electricity savings of different AC operation modes for residential houses of Riyadh city are presented. The results from our computer simulations show that the solutions intended to reduce energy consumption effectively, particularly in the advance mode of operation, resulted in a 30% to 40% increase in total annual energy savings.
