1. A window comprising:
- an outside glass pane for interaction with outdoors comprising a low emissivity layer that transmits actinic radiation,an inside glass pane for interaction with indoors comprising a photochromic glass and a non-photochromic glass separated by a low emissivity interface positioned therebetween,the inside glass pane is spaced apart from and disposed substantially parallel to the outside glass pane, andthe actinic radiation transmitted by the outside glass pane and low emissivity layer reduces visible light transmittance through the photochromic glass.

Abstract
A multi-pane window having a low emissivity layer and a photochromic glass. The window includes at least two panes of glass. An outside pane for interaction with the outdoors and an inside pane spaced apart from the outside pane. The outside pane includes a low emissivity coating. The inside pane includes a photochromic glass. The outside pane transmits solar light wavelengths. The photochromic glass is darkened upon exposure to light transmitted by the outside pane.

19. A window comprising:
-
an external glass pane comprising a low emissivity layer, the external glass pane transmits solar light from a building exterior comprising actinic radiation, an internal glass pane comprising a photochromic glass and a non-photochromic glass separated by a low emissivity interface, the internal glass pane is spaced apart from and disposed substantially parallel to the external glass pane, and the actinic radiation transmitted by the external glass pane darkens the photochromic glass and reduces visible light transmittance through the photochromic glass. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A building including a multi-pane window installed between an interior and an exterior of the building, the window comprising:
-
an exterior glass pane comprising a low emissivity layer, the exterior glass pane and low emissivity layer transmit actinic radiation from the building exterior, an interior glass pane comprising a photochromic glass, a non-photochromic glass, and an interface disposed therebetween including low emissivity composition, the interior glass pane is spaced apart from and disposed substantially parallel to the exterior glass pane, and the actinic radiation transmitted by the exterior glass pane activates the photochromic glass to reduce visible light transmittance through the photochromic glass by 40% or more. - View Dependent Claims (30)
