Reactive Nano Glass

The company RavenBrick has utilised nanotechnology to develop a glass that automatically changes tint according to its temperature. When the glass gets hot the windows darken to block incoming solar radiation, and when it is cold they are clear to allow the free heat in — all without electricity.

On a hot sunny day, a RavenBrick window will transform to a darkened state, blocking hot sunlight from the building’s interior. On a cool day, the window will stay in its neutral state and transfer solar heat to the inside.

The benefits of this technology applied to windows include:

  • Significantly reduced heating and cooling costs, the greatest energy consumers in commercial buildings
  • A fully automatic transition, free from wires or activation devices
  • Easy to install on new windows or retrofit to existing ones
  • Affordability, particularly compared with current smart windows
  • A quantifiable and short-term ROI which can be easily determined for any specific building
  • Aesthetic appeal, enabling the use of natural sunlight in building design
  • Improved temperature and light-glare comfort for people in the building
