PDLC uses little power, but it is not solar shading: the frosted state scatters light but blocks only a limited amount of solar heat. It does block virtually all UV radiation. Combining it with solar-control or low-e coatings (in insulating glass) can lower the solar heat gain. The biggest sustainability benefit is often replacing curtains and blinds and making better use of daylight in interior spaces. [11]
