RavenBrick is developing a window that knows when it’s hot enough for shade.
The Denver-based company has been working on a window coating that creates a heat-blocking tint triggered by the outdoor temperature. The company is in the process of raising $3 million in venture capital with plans to build a factory that will start operating in about a year, according to co-founder and President Wil McCarthy.
One of the trends in building design is to use large windows to bring in daylight, which creates a pleasing workspace and lowers the need for artificial lighting. One of the challenges with floor-to-ceiling windows, for example, is excessive heat from sunlight, or “solar gain.”
