| Popis: | Thermochromic (TC) windows are able to adjust solar radiation transmitted into buildings in response to different window surface temperature. Vanadium Dioxide (VO2) is the most common TC material used for TC window, as it can reduce near infrared (NIR) solar transmittance to block undesired solar heat gains during the hot day when the surface temperature above its transition temperature. However, few have studied the effect of TC window on the indoor luminous environment. In order to improve the daylighting control, an innovative iron-liquid based TC window film with control on the visible spectrum was introduced and applied in cooperation with VO2 based TC material in this study. The cooperative performance of these two types of TC materials was discussed under three climatic conditions in China, which are Beijing, Shanghai and Guangzhou. The results show that their energy saving potential and daylighting regulation ability that affected by the cooperative implement is highly depended on climates. |
