Smart window technology, thermally insulating fenestration that changes color at the flip of a switch, is the next wave in windows. Smart glass’ most visible application right now is in the auto-dimming rearview mirrors in high-end cars. But the technology is poised to move out of the Mercedes and into homes and businesses, where it could potentially save one-eighth of all the energy used by buildings in the U.S. if it replaced all the conventional windows in the country, according to researchers at the National Renewable Energy Laboratory (NREL) in Golden, Colo. That’s about 5 percent of the nation’s entire energy budget.
When you walk into a darkened room, usually you flip on the lights or open the shades. But soon you could opt instead to let the sunshine in by hitting a switch to send an electrical current coursing through your windows.
