The U.S. Department of Energy (DOE) today announced the winners of the first phase of the Building Envelope Innovation Prize, which targets high-performance, cost-effective secondary glazing systems to improve efficiency of commercial windows. DOE selected seven semifinalists to receive $50,000 each for their design concept submissions.
Sponsored by DOE’s Building Technologies Office (BTO), the prize is advancing novel solutions for upgrading inefficient commercial and high-rise residential building windows to enable equitable decarbonization and optimize building envelopes for electrification. Secondary glazing involves installing an additional windowpane on an existing window to improve insulation while minimizing cost and disruption.
