Thermochromic window structures
First Claim
1. A window comprising at least one pane of glass or plastic, and a sunlight responsive thermochromic (SRT) device including a layer of a thermochromic material that reversibly increases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material increases and decreases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material decreases for temperatures within the active range of the system, a pair of transparent substrates, the layer of the thermochromic material being interposed between the substrates to form a laminate;
- anda space between the at least one pane of glass or plastic and the SRT device.

Abstract
An energy efficient, thermochromic device that may be used to allow sunlight or solar radiation into a building or structure when sunlight is absent or at high sun angles and substantially blocks solar radiation when sunlight is directly on the window.
