Intuitive glass controls daylight solar heat

Smart Windows – A new window automatically adjusts to block UV rays when it’s sunny outside and let in more light when it’s cloudy.

Generation 3 thermochromic windows from Denver-based RavenWindow optimize natural light, block UV rays, and mitigate glare—three key factors for occupant health, wellbeing, and comfort, the manufacturer says.

The thermally activated window transitions from a clear state to a tinted state during peak heat hours, and then back to a clear state as the outside temperature cools, all within minutes.

In addition, the light-blocking glass can provide significant energy savings, up to 30 percent on utility bills, the firm says.

Recent research has pointed to a direct connection between natural light stimulating human visual, metabolic and circadian rhythms. RavenWindow’s tint-transitioning technology optimizes natural light to help synchronize these rhythms to promote more alertness, improved mood, and faster cognitive processing.

“RavenWindow reduces solar heat gain, glare and UV degradation while maintaining a view and connection to the outdoors”, says Lance Kling, Regional Sales Manager. “Our products are a fraction of the cost of electrochromic glass and are priced to be competitive with high-performance low-e glass and blinds.”

NOTE: Thermochromism is the property of substances to change color due to a change in temperature. A mood ring is an excellent example of this phenomenon, but thermochromism also has more practical uses, e.g. in baby bottles (changes to a different color when cool enough to drink) or kettles (changes when water is at or near boiling point). Thermochromism is one of several types of chromism.
