Abstract |
The purpose of this study was to conduct an energy performance evaluation using TRNSYS18 and test bed construction for the development of smart skin windows that can be controlled by solar radiation. For smart skin windows, clear glass (SHGC : 0.13 to 0.57) and low-e glass (SHGC : 0.06 to 0.25) according to the range of the Solar Heat Gain Coefficient (SHGC) were divided into 1.4 (W/㎡?K), 1.07 (W/㎡?K), and 0.7 (W/㎡?K), respectively. The results are as follow, compared to the standard. For U-Value 1.4 (W/㎡?K) when using clear glass, the cooling energy was -32.0% and the heating energy was 1.5%; when using low-e glass, the cooling energy was -37.0% and the heating energy was 64.4%. For U-Value 1.07 (W/㎡?K) when using clear glass, the cooling energy was -30.9%, and the heating energy was -8.5%; when using low-e glass, the cooling energy was -36.1%, and the heating energy was 45.6%. For U-Value 0.77 (W/㎡?K) when using clear glass, the cooling energy was -30%, and the heating energy was -27.8%; when using low-e glass, the cooling energy was -34.8%, and the heating energy was 20.1%. Thus, the results show that the cooling and heating energy is the most saved when using the clear glass at U-Value 0.77 (W/㎡?K). |
