It’s estimated that 10 percent of all the energy used in buildings in the U.S. can be attributed to window performance, costing building owners about $50 billion annually, yet the high cost of replacing windows or retrofitting them with an energy efficient coating is a major deterrent. Berkeley Lab researchers are seeking to address this problem with creative chemistry—a polymer heat-reflective coating that can be painted on at one-tenth the cost.
