The Building Information Modeling (BIM) environment was utilized to create the necessary electrical plans and determine the available surface areas required for implementing this system. The existing electrical loads in the school (for lighting and fans) were initially calculated, followed by determining the suitable photovoltaic system to meet these loads, including the number of solar panels and the surface area needed for their installation. The calculated capacity of this system amounted to 12.510 kilowatts, composed of 12 solar panels, requiring an installation area of 32 square meters. The required capacity of the photovoltaic system was recalculated after replacing the school's electrical equipment with devices operating on direct current (DC), resulting in a system capacity of 7.260 kilowatts, providing a savings of 5.25 kilowatts, i.e., by 42%. The number of panels required to power the school's loads decreased to 6 panels, reducing the necessary installation area to 16 square meters, i.e., by 50%. This replacement also eliminated the need for batteries and expensive inverters, resulting in significant cost savings and a substantial reduction in electricity consumption from the main grid.In Sweida Governorate، there are a total of 253 elementary schools. If these schools were transformed into zero-energy buildings following the method outlined in this research, it would lead to a daily saving of 1328.25 kilowatts from the main grid. 2023 2023 58 71 10.54216/IJBES.070104 https://www.americaspg.com/articleinfo/22/show/2214
