Example of energy and cost savings

According to the actual monitoring of the heat generated by solar energy in Shenzhen summer, the direct heat load generated by solar energy is 900W/m2, considering the average heat load conversion of glass is 500W/m2, and the annual total sunshine time is 1608 hour in Shenzhen, thus the annual energy consumption per square meter of glass increased by heat load generated by solar radiation into the indoor is ( 500W/m2 X 1608h ) / 4 = 201 kwh. If the total solar energy insulation rate of smart optically-controlled window film is 80%, then the annual energy-saving is 201 kwh/m2 X 80% = 160.8 kwh/m2.

GRI SMART FILM

PDLC Film consists of a polymer matrix of liquid crystals enclosed by electrically conductive Indium Tin Oxide-coated PET film. The resulting PDLC Film has wiring attached to a conductive copper strip (busbar) along the film’s edge. This wiring isconnected to a step-down transformer through which power is supplied for the “on” (clear) state.
