Correct Answer
Energy efficient windows
According to the company, "the specialized glass solution includes double pane glass and sandwich glass, which has a layer of patented material that reflects a majority of solar radiant heat"
How impactful could energy efficient windows be for building energy efficiency? While authentic data are a bit sketchy at tthis stage, this report from the US suggests that it could cut about 10% of a home's energy bills. Another report from the EU seems to credit energy efficient windows with even higher impact, "simply doubling the replacement rate of windows, in line with the European Green Deal, would achieve 20% of the EU’s energy efficiency targets for 2030"
And oh, by the way, glass that reflects the heat of sunlight is something prominent glass makers are working on too (not surprisingly). Here's a page on Sun Ban, Saint Gobain's special glass to reflect heat achieved through a special pyrolytic coating on the glass.
