Emili window / Window

Emili window
Emili window

The Emili window automatically controls the luminous flux entering a room based on changes in the surrounding environment. As the temperature increased, the transmittance decreased. This blocked external heat sources and the sun’s infrared light, thereby achieving the desired effect of cooling the inside of the buildings and meeting the objective of reduced air-conditioning power consumption. As the temperature decreased, the transmittance increased. This allowed sunlight to penetrate into the building, thus increasing the room temperature and reducing heater power consumption.
