This paper discusses applications of Building Integrated Photovoltaics (BIPV) to retrofit residential buildings in Egypt to self-produce their own Energy needs, as the residential sector is the largest consumer of fossil fuels in Egypt. This requires attention to renewable Energy applications as a sustainable strategy that helps reduce the burden on the local economy, which is currently facing economic problems such as Inflation, high prices of Fossil Fuels, and a shortage of hard Currency. Also, this strategy reinforces Egypt's desire to achieve comprehensive sustainability by 2030 AD by increasing Energy production from renewable sources Such as Solar Energy, the research methodology follows an analytical theoretical approach. It begins with a theoretical study of the details of BIPV, followed by an analytical examination of residential projects that implement this concept from where the impact of these projects on Energy production and the reduction of harmful carbon emissions. Furthermore, a SWOT analysis evaluates the implementation of the integrated photovoltaic system in Egyptian buildings, aiming to provide suitable recommendations that address Weak points and threats to expanding BIPV applications. The research underscores the importance of relying on integrated photovoltaic applications in residential buildings due to their positive effects on the local economy, Individual income, and decreasing harmful Carbon Emissions. And the importance of collaborative efforts for widespread implementation across all residential buildings and others.
