With corporations coming under increasing pressure to meet social obligations, there is a drive towards promoting eco-friendly commercial designs. While glass use has generally been considered a mark of energy inefficiency, new advances in window design mean that this is no longer the case — glass looks set to become a staple of future eco-builds. Consider installing photovoltaic glass, which has the next generation of solar cells incorporated directly into the window surface. This allows a once power-sapping design feature to begin generating its own energy.
