摘要

With the global energy crisis intensifying due to population growth and the depletion of traditional energy sources, there is a heightened focus on the need for efficient energy use and the promotion of sustainable practices. The concept of net-zero energy buildings has emerged as an innovative strategy to mitigate the impacts of this crisis and support environmental conservation efforts. To achieve a net-zero, a building must be capable of generating at least a portion of its own energy through renewable sources such as solar energy, which is the most common and often easiest to integrate. However, geothermal and wind energy have also become increasingly popular, highlighting the research gap and problem this paper addresses. The research adopts a descriptive analytical approach, including a comprehensive review of the literature, followed by an analytical study examining international schools that have implemented zero-energy strategies in climates similar to Riyadh's hot environment. This involves a deep analysis of successful practices, identifying obstacles, comparing results, and evaluating the effectiveness of the strategies used. This contributes to a better understanding of how to achieve desired goals more effectively and efficiently. Furthermore, the study employs an experimental method using the DesignBuilder simulation software to model the impact of integrating renewable energy sources to achieve zero energy in a school in the Riyadh area. The results demonstrate the potential for significant energy savings, with cooling load reductions of 87.84% through the use of the EarthTube system. Overall, 95% of the school's energy demand was met by onsite renewable energy generation, with contributions from photovoltaic systems (72.44%) and wind turbines (26.24%), while battery storage and grid integration ensured continuous supply and system stability. These findings affirm the research goal of achieving zero energy and supporting sustainability. The study recommends the establishment of a central committee under the Ministry of Education to oversee the transition toward net-zero energy schools, including updating standard school design specifications to integrate energy efficiency and eliminate unnecessary energy loads. It also highlights the importance of promoting energy awareness through interactive monitoring systems and media engagement. Furthermore, the integration of renewable energy sources such as solar and wind and the expansion of applied research on net-zero energy buildings design strategies are essential to achieving Saudi Arabia’s educational sustainability goals by 2030.
