건물일체형 태양광(BIPV) 발전형 커튼월의 신뢰성 검증을 위한 실대형 성능 평가에 관한 실험적 연구

Purpose: The Building Integrated Photovoltaic (BIPV) module is a module that applied building as curtainwell and acts as a building exterior while simultaneously producing electricity. BIPV modules can be used in various forms (curtain wall, roofing material, etc.), Among them, the BIPV curtain wall is an actively being developed building material that can effectively receive sunlight by replacing the building envelope. BIPV Curtain wall should simultaneously have reliability as both building material and PV module because the BIPV curtain walls are directly exposed to the harsh environment and cause building exterior damaged. Method: Through the analysis of domestic and international standards, the BIPV curtain wall full scale evaluation method is derived, and the method is verified by practical full scale evaluation. Result: The BIPV curtain wall performance evaluation method was developed and in order to verify the validity, we built BIPV Mock-up which simulated actual construction. Structural performance was evaluated through air infiltration and exfiltration test, water penetration test, wind pressure test and structural deformation test. Electrical continuity test and insulation test were performed to evaluate the electrical performance. In addition, performance of the module applied to the mock-up was evaluated by comparing power generation before and after each tests.
