When it comes to scrutinizing architectural materials for their energy efficiency, one offender stands out above the rest: glass. Windows and curtain walls act as one of a building’s main outlets for heating and cooling losses, and as society advances into its more environmentally-conscious future, new, passive solutions will need to be developed to mitigate buildings’ energy footprints. In recent years, various smart glass technologies have been designed to automatically regulate light and heat based on environmental conditions. Yet their high price tags have prevented them from achieving widespread application. Now, a team of MIT researchers may have discovered an alternative to smart glass that could come at an affordable price.
