Summary:This study was to evaluate a commercial product of building integrated photovoltaic and thermal system passed through air. This air based BIPV/T system has not applied to building in Korea, so it was needed to identify the combined performance of energy efficiency that created electricity and thermal. The mock-up model composed with wall and roof typed BIPV/T system was constructed on the roof top in one of pilot houses located in Daejon, Korea. The following is the result of performance. As for BIPV, at wind speed of 20CMH/㎡, the efficiency of acquired electricity was 13.2 %. At wind speed of 54CMH/㎡, the efficiency of acquired electricity was 14.9 %. As for thermal energy produced by thermal collector, at wind speed of 20CMH/㎡, the efficiency of acquired thermal energy was 14.8 %. At wind speed of 54CMH/㎡, the efficiency of acquired thermal energy was 33.4 %. From this performance, the maximized energy combined thermal and electricity reached 48.3%.
