Abstract
A window assembly having at least one pane is presented for use in a building. Positioned within the pane are a plurality of spaced-apart micro-louvers which extend substantially across the length of the pane. The micro-louvers are positioned to block transmission of direct sunlight through the pane when the sun is at a selected angle above the horizon or higher. The angle at and above which direct light is blocked can be selected to be approximately 30 or 45 degrees above the horizon, for example. The angle can be selected based on the latitude of the location of the window assembly, the time of day during which direct sunlight is blocked, etc. The micro-louvers may have reflective surfaces, be colored as desired, be opaque or translucent.
