“How can we have windows that darken at command?”
One of the biggest consumers of energy in the built environment are HVAC systems. Although many people try to avoid this by putting blinds over their windows, many times it won’t do the job. So how can we use our engineering mindset to solve this problem? Well, what if we were to have a window that can darken at command? This is the idea behind Electrochromic Windows, whose material becomes darker when voltage is applied to it. Electrochromic windows can save large amounts of energy, but are also quite expensive to implement and have questionable long-term durability.
