Pros and Cons of electronically switchable smart glass
Of course, electronically switchable smart glass has its drawbacks as well. While they may save in energy costs, smart glass is no doubt an expensive luxury. The technology is still relatively new, hence the high price. In electrochromic glass, the transformation between transparent and dark also takes several minutes. The transformation begins on the outer edges and moves its way towards the center. Some switchable glass takes electricity to remain transparent, which could be a problem during power outages. While not all electronically switchable glass requires electricity to retain its hue, it does use it to transform.
In general, smart glass is an energy saving investment. It costs very little to power the glass and is more convenient than typical methods to darken a room. Where the cost is initially high, it does save on energy costs. Privacy and convenience are two important benefits of switchable glass, although it is also limited by the technology itself. There may still be room for maintenance and repair. However, given its simple structure, it can last for a long time.
