Textile Industries Mechanical Engineering and Techniques Department, Faculty of Mechanical and Electrical Engineering, Damascus University, Damascus, Syria Bilal Zaarour Building Integrated Photovoltaics (BIPVs) systems are a promising and innovative technology that has gained significant attention in the last decade. These systems aid buildings in meeting their energy demands, thereby addressing the rising energy needs. This case study was conducted on the Engineers Association Branch in Latakia.The experimental method was used to calculate the needed electrical loads, it was found that replacing 74m² of south-facing traditional glass windows of the Syndicate of Engineers building, with polycrystalline photovoltaic windows (P-Si), will produce 59.2 kilowatts, which is a sufficient amount to cover the total electrical load for the lighting and the operating office equipment, this mean to have a zero-energy building over a period of 30 to 35 years, in addition to save 65000kg of CO2 for the 30 later years. This study is particularly important in Syria's reconstruction phase, which will involve the construction of numerous tower buildings with large glass facades, where space for installing solar panels may be limited on the roofs, Therefore, the integration of solar panels in the facades is the ideal solution to cover the needed loads. 2023 2023 29 38 10.54216/IJBES.060202 https://www.americaspg.com/articleinfo/22/show/1889
