Office buildings consume a huge amount of energy which is responsible for greenhouse gas emissions as well. On the other hand, the photovoltaic systems play a copious role in building energy load reduction and at the same time supply clean electrical energy to the building. In this study, south-facing applied photovoltaics system was built to the exterior of the existing office building with a 0.5 m air gap having 13 m × 4 m dimensions with 8 × 4 of array layout to form building-applied photovoltaic (BAPV). The thermal response of this BAPV system was studied under real outdoor conditions for Dalian. Moreover, the daylighting illuminance (lux) was measured at the working plane inside the office room due to the effect of BAPV façade construction. The 19.8% of power generation efficiency was found for such custom-made PV modules. In addition, the daylighting illuminance was found to be 300–500 lx till 14:30 and afterward led to decrease and have to switch on the artificial daylighting for indoor comfort.
