Here's a market opportunity - autosensing thermoreflective glass. As long as making it doesn't use more energy than it saves

The idea is good - as temperature rises the glass darkens. It's hardly new, there are similar but different methods to do this, but it may be a cheaper and more scalable way. As long as the processes involved in making it don't overwhelm the savings.

RavenWindow automatically changes transparency with temperature
The key element in the window is a layer of thermoreflective material between the internal and external layers of glass. When the temperature of that material exceeds the threshold, it becomes reflective, bouncing off at least 90% of the incoming solar energy.
