The demand for sustainable energy solutions is driving a surge in building-integrated photovoltaics (BIPV), leading to an array of innovative products hitting the market. To aid architects, developers, and other stakeholders in planning BIPV projects, experts from the IEA-PVPS Task 15 have introduced a new assessment tool.
This multi-dimensional evaluation method draws from the experiences of existing BIPV projects, enabling comparisons across various performance aspects. Divided into energy, economic, environmental, and optical/visual categories, the tool assigns numerical ratings based on defined performance indicators. Additionally, it classifies different BIPV installation types.
Initial tests on BIPV roofs, facades, and external devices have validated the methodology. However, challenges such as limited data availability and subjective visual assessments remain. Additionally, early-stage BIPV projects face unique hurdles due to the use of emerging technologies.
Despite these challenges, the tool offers promise in guiding the development of optimized BIPV systems. Its ability to evaluate various performance aspects can pave the way for sustainable building practices in the future.
