“…Adjusting the temperature set point to be in the range of 23-25 • C instead of 19-22 • C during official working hours (from 7 a.m. to 5 p.m., five days a week) could lead to an average energy savings of around 12% of the total, or the average energy consumption of AC systems with zero SPBT. This is what studies conducted in the Gulf region have shown, studies such as Alardhi et al [40], Esmaeil et al [41], Kharseh et al [42], and Al-Mumin et al [43]. These studies report saving 10-14% of the cooling load in the Gulf region by increasing the temperature set point by 2 • C. To determine the annual amount of energy that could be saved with the set point in the range of 23-25 • C during official working hours, the results of the research mentioned earlier were relied upon in this field.…”

Electricity is used in educational buildings, and there are now numerous attempts to reduce consumption, achieve sustainability, and protect the environment. This paper aims to study energy consumption, identify opportunities to rationalize energy consumption, and propose solutions at Sulaiman Al-Rajhi University in the Kingdom of Saudi Arabia in order for the university campus to become sustainable. The results showed that total annual electrical consumption totaled 13,859 MWh in 2021. The air conditioning system, other devices, and lighting have the percentage of consumption 79, 14, and 7% of the total, respectively. Electricity consumption intensity was approximately 145–155 kWh/m2, and the per capita intensity was approximately 12,987–16,351 kWh, in the period 2017–2021. The price of the electrical energy generated on the university campus ranged between 0.3 and 0.53 SR/kWh in 2021, while the electricity tariff from the grid for educational buildings was 0.18 SR/kWh. This means that the public grid was 50% cheaper than campus-generated electricity. At the price of energy generated by generators, the total simple payback time (SPBT) for the suggested energy conservation measures (ECMs) is 4.13 years, whereas the SPBT is 8.96 in the case of the consumption of the electricity supplied by the national grid. The environmental benefits of the proposed ECMs were also identified.

“…They showed improving EE in buildings could provide space cooling with a reduction of 28% of the annual energy consumption of residential buildings. The application of envelope thermal insulation, proper adjusting of the indoor set temperature, and use of lighting effects lead to a reduction of energy intake up to 46% in the residential building in the city of Doha (Kharseh, Al-Khawaja, and Hassani 2015). Results from a survey of public perception about smart grids, smart meters, RE, and the environment in Qatar revealed that the majority of the respondents were unaware of any of the following energy-saving materials at homes (Abdmouleh et al 2018).…”

Global warming has risen as a primary global concern. It has stimulated interest in the development of the renewable energy (RE) system. Studies demonstrated that the regions of Gulf Corporation Council (GCC) such as Bahrain, Kuwait, Oman, Qatar, Kingdom Saudi Arabia (KSA), and United Arab Emirates (UAE) face several changes in the form of uncertain weather conditions. Given the strategic location of the Gulf States and its enormous oil and natural resource, it is characterized to hold potential for using renewable energies such as solar, wind, and geothermal energy for meeting the power production needs. Previous studies suggested that energy consumptions such as crude oil and fossil fuels are the major sources of providing economic benefits to the states. The high oil price, deterioration of the financial markets, and incident of Arab Spring has shifted the working at a national and international level, making it important in using RE resources to generate excessive energy. The primary focus was to explore the scope of energy efficiency (EE) and the use of solar, wind and geothermal energy resources given their proliferation potential for the GCC region. The review assessed the energy and electricity consumption trends in the region. Also, it discussed the problems related to the effects of dust accumulation on devices. Moreover, it also highlighted the use of various computer interfaces that demonstrate the feasibility to use various RE technologies. Further, it draws conclusions and recommendations based on the issues.

“…This implies that when a country or a region has a large population, electricity consumption also grows. Many researchers have argued that there are several factors related to population and load demand, which are lifestyle, gadget, and electrical appliance usage [13,23,24]. Fig.…”

As a developing country, Malaysia is expected an increment on their electricity consumption align with growing of economy, population as well as industrial demands. For that reason, this paper brings an analysis that considered some macro factors identified as geographical parameters, meteorological parameters, and economic parameters which believed will effect the demand in electricity over the country. However, the case study for this research is focusing the demands in the area named Johor Bahru and Skudai due to the higher electricity consumption in Johor, Malaysia. The correlation coefficient is introduced as a tool to measure the significant factors influenced the demands. From the result obtained, it shown that Gross Domestic Product (GDP), population and maximum temperature were affected the electrical load demand pattern based on their Pearson Correlations. As an advantages this finding will help others researcher and electrical utilities in forecasting their future demands.
