PPG Earns DOE Funding to Develop Dynamically Responsive IR Window Coating
PITTSBURGH – PPG Industries’ flat glass business has received $312,000 from the U.S. Department of Energy (DOE) to develop a dynamically responsive infrared (IR) window coating that will block heat in the summer to reduce air-conditioning costs and transmit solar heat in the winter to reduce heating costs.
The funding is part of an award of up to $750,000 being shared with project leader Pacific Northwest National Laboratory (PNNL). PPG and PNNL are designing a coating that can “switch” from a solar IR-reflecting state to a solar IR-transmitting state while maintaining high levels of daylight transmittance in either condition. PPG will provide an additional $78,000 in cost-sharing.
