Purpose: As the energy consumed by buildings increases, the demand for research and technology development to solve this problem is increasing. Among them, the building envelope system can regulate the influx of climate factors that make up the outside environment into the room. This system is applied to various buildings because it can minimize the use of energy such as lighting. Among them, the BIPV system is a representative eco-friendly envelope system that integrates the solar power generation system and satisfies the function of the envelope and renewable energy generation at the same time. However, the efficiency of PV is generally known to be good at 30 degrees south, and the power generation varies according to region and time. In this regard, this study aims to provide basic data for eco-friendly design by conducting light environment performance evaluation of the outer skin that combines PV with kinetic structure. Method: In this study, In this study, a 1:1 scaletestbed was established for performance evaluation, and PV power generation and lighting power energy were evaluated according to the kinetic skin variables. Results: The results of this study are as follows: 1) BIPV power generation was the highest at 20 degrees and 110 degrees, respectively. Due to the angular change through the kinetic structure, the rate of increase in power generation was 140.29% and 16.03%, respectively. 2) The power consumption by indoor lighting device was higher than the standard without installation. However, in both summer and winter, the uniformity increased, and as the angle approached 0 degrees, the lighting energy decreased. 3) From the perspective of saving building energy, each case showed 20 degrees for the lower limbs, 10 degrees for the winter solstice and 10 degrees for the winter solstice. The lower layer is considered to be effective in the installation of shells because of the high energy reduction rate at high angles of PV generation. However, the winter solstice satisfies the average illuminance of 400 ㏓ when the outer shell is not installed, so the energy reduction rate is 10 degrees and 0 degrees, which is the angle that can maximize the inflow of sunlight. Therefore, more research and technology development may be needed to solve the problem of increased energy consumption in the winter solstice.
