The aim of this study is to evaluate how much would the building energy consumption save by applying DSSC BIPV window system in office building that is possible to control the transmittance and express the color. For this, physical characteristics such as transmittance and reflectance, U-factor of DSSC ars analyzed and an annual energy consumption that is connected to dimming control is calculated when DSSC BIPV window is applied by alternate clear window system. In particular, interior and exterior blind system according to the operation condition are applied for analysis because DSSC BIPV window system has low transmittance and those features make the effect of replacement of blind. As a result, It is possible to reduce the an annual energy consumption as much as 4.1% by just change the clear double window system to DSSC BIPV double window system. When the thermal insulation properties of DSSC BIPV window by applying low-e coating and making triple window are improved, energy saving ratio is about 9%. Plus, energy saving ratio of 25~28% in lighting energy consumption is possible when the dimming control system with DSSC BIPV window is adopt. Finally, DSSC BIPV window is more effective than blind system. |
