Abstract

In this study, daylighting and energy consumption models were established for an office building equipped with electrochromic windows. Two new daylighting indices were introduced. With the above model and indices, the study of transmittonce optimization was carried out in Changsha, a region characterized by hot summers and cold winters. The results indicate that during the transitional and heating seasons, the optimal transmittance settings for the four stalls of electrochromic windows are 51.40%, 18.80%, 4.80%, and 1.00% in Changsha, respectirdy. It can achieve the best comprehensive performance with useful daylight illuminance of 75.80% and 50.91%, and energy consumption of 6.70 kWh/m² and 11.88 kWh/m² in the transitional and heating seasons respectively. In the cooling season, the optimal transmittance settings are 51.40%, 32.60%, 23.60%, and 14.10%,respectirely, resulting in a useful daylight illuminance of 92.28% and energy consumption of 8.30 kWh/m². By adopting the above strategy, the annual useful daylight illuminance increased by 40.78%, and the annual percentage of imperceptible glare increases by 59.75%,compared with ordinary double-layer Low-E glass. Due to the good energy-saving performance of ordinary double-layer Low-E windows and the small difference in solar heat gain coefficient between the light and dark state of electrochromic windows, the annual total energy consumption per unit area is only reduced by 4.14% with electrochromic windows.
