1. A method, comprising:
- determining, by a computer for determining an estimated brightness factor for a fabric, an estimated openness factor of the fabric based on a Munsell chroma of the fabric;
determining, by the computer, an estimated visible light reflectance of the fabric based on a Munsell value of the fabric;
determining, by the computer, an estimated diffusion factor of the fabric based on a Munsell hue of the fabric; and
determining, by the computer, the estimated brightness factor based upon the estimated openness factor, the estimated visible light reflectance, and the estimated diffusion factor.

Abstract
Brightness factors associated with shade fabric may be utilized when shading a building. A brightness factor may incorporate an openness factor, a visible light reflectance, a diffusion factor, a color, or other characteristics of the shade fabric. The brightness factor may be utilized when selecting a particular shade fabric for a room, building or other location. Additionally, the brightness factor may be utilized by an automated shade control system. The shade fabric selection may affect the building envelope by facilitating the optimization of daylighting, reduction of artificial electric lighting needs, minimization of glare conditions, and reduction of thermal load.

9. A method of shading a room, the method comprising:
-
selecting a shade fabric for use in constructing a window covering, wherein the shade fabric is selected based on a brightness factor of the shade fabric, and wherein the brightness factor is determined by measuring an openness factor, a visible light reflectance, and a diffusion factor of the shade fabric; placing the window covering between a window and a light source; and moving the window covering to modify the brightness in the room. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
