It appears that the future of windows and doors will involve the confluence of technologies that previously have had little to do with fenestration products. Some examples of improved fenestration functionality being conceptually introduced around the industry involve automatic operation of fenestration products, as well as integrated security, locking and alarm systems. There are also plans for electrochromic, thermochromic and photochromic glazing controls, as well as automated shading systems for dynamic control of solar gain and daylighting, and for Zero Net Energy buildings with power sources (such as photovoltaics) and associated control systems integrated into windows. And, even the integration of devices that detect and monitor the status of the window itself as well as environmental conditions and the status of other building systems is a concept on the drawing board.
