Offices have a great environmental impact due to wasting natural resources, which blocks the ambient light and uses a large number of artificial illuminations. Besides, under high thermal conduction in summer, running air conditioners causes an excessive waste of energy. The natural resources of ambient light are usually being sacrificed by the tinted window film, but using bioilluminant can solve this problem. In addition to the direction, the illuminance of the light can be controlled just like curtains, the water medium also can reduce the temperature conductivity.
