Abstract

This study aims to develop a prefabricated BIPV roof system, in which most processes are completed in a factory and only simple installation is required on-site, as an alternative to the conventional BIPV method where all processes are carried out on-site. The effectiveness of the system is verified through performance evaluation. The waterproofing performance evaluation confirmed that the three-stage waterproof structure effectively prevented water infiltration. Additionally, fire resistance tests demonstrated satisfactory results, with load-bearing capacity at 55 minutes, integrity at 55 minutes, and insulation at 50 minutes, thus fully meeting established standards. The thermal insulation performance evaluation revealed that some performance criteria were not satisfied due to thermal bridge occurrences. Consequently, further research, including the application of thermal break materials, is required for applicability in general buildings. The developed system significantly reduced installation time by up to 98% compared to conventional on-site installation methods, highlighting its strong suitability for environments such as industrial complexes that require rapid construction. In conclusion, the developed prefabricated BIPV system has proven to offer rapid installation, excellent maintenance convenience, and superior waterproofing and fire resistance performance. Future improvements in thermal insulation and system flexibility are necessary to extend its applicability across various architectural environments.
