The main purpose of Window in building is taking a view of the outside and then adds subordinately it plays decreasing the lighting and heating energy through Solar Heat Gain from the daylighting. However, the problem that increase the energy consumption of lighting and cooling is incurred because the blind is unreasonably operated in many curtain wall offices; the blind is remained closed most of the time without being adjusted by occupants. Indoor light environment is analyzed when adjusting a-Si BIPV Window that having Visible Transmittance of 7.5% as an alternative about such problems. The experiment is targeted at Full-Scale Building adjusted a-Si BIPV Window. The Daylight Factor through the illuminance measurement is analyzed. In addition, the luminance contrast through luminance measurement between the window and the background is analyzed. As a result of the analysis, securing the appropriate value of daylight factor is possible at the indoor visible environment because the low visible transmittance of a-Si BIPV window prevents inflowing the excessive daylight. At the same time, a-Si BIPV window can make comfortably view outside to the occupants who looking the window. Consequently, when the a-Si BIPV that enables inflowing the suitable daylight is paired with lighting control system it is lowerable that wasted lighting energy consumption becouse of the blind unreasonably operated. Moreover, the appropriate lighting control restrain the heating from the lighting and then it judged that the coolign energy consumption that is the major section of energy spending in the office building will be saving. |
