A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing heat-loss from leaky windows. The material—a transparent film made by weaving carbon into the atomic lattice of boron nitride—forms a thin, tough layer that reflects heat, resists scratches and shrugs off moisture, UV light and temperature swings.
The researchers simulated how the material would behave in an actual-sized building in cities with cold winters like New York, Beijing and Calgary, showing it improved energy savings by 2.9% compared to existing alternatives. With over 4 billion square feet of new windows installed annually in the U.S. alone, the savings can add up.
