To reach carbon neutrality by 2050, China still faces high carbon emissions. To maintain comfort and GDP growth, we need to use renewable energy sources to reduce building emissions. Building Integrated Photovoltaics (BIPV) combines user needs with energy production, cutting reliance on fossil fuels. Studies suggest BIPV can achieve up to 70% energy savings. With advancing technology and lower costs, BIPV is promising. Modular construction offers benefits like quick assembly and cost-effectiveness. This study proposes creating an adaptive BIPV modular construction optimization tool.
