Automated shade control in connection with electrochromic glass
First Claim
1. A system, comprising:
- a glass controller configured to adjust a variable characteristic of a glass; and
a central controller configured to control the glass controller and a motor associated with a window covering, wherein the central controller utilizes a proactive algorithm, and wherein the proactive algorithm incorporates a clear sky algorithm.

Abstract
Automated shade systems may comprise controllers that use algorithms to control operation of the automated shade control system and components thereof, for example window coverings, glass having variable characteristics, and so forth. These algorithms may include information such as: 3-D models of a building and surrounding structures, shadow information, reflectance information, lighting and radiation information, information regarding one or more variable characteristics of glass, clear sky algorithms, log information related to manual overrides, occupant preference information, motion information, real-time sky conditions, solar radiation on a building, a total foot-candle load on a structure, brightness overrides, actual and/or calculated BTU load, time-of-year information, and microclimate analysis.

6. A method, comprising:
-
modeling, by an automated shade control system, at least a portion of a building and at least a portion of the surroundings of a building to create a shadow model; using, by the automated shade control system, the shadow model a first time to calculate the presence of calculated shadow at a first location of interest; and communicating, to a first glass controller, an instruction configured to adjust a variable characteristic of a first glass responsive to the calculated shadow at the first location of interest.

7. A method, comprising:
-
receiving, at an automated shade control system, an input from at least one of a photosensor or a radiometer; generating, responsive to the input, a first instruction to a glass controller, the first instruction configured to cause the glass controller to adjust a variable characteristic of a first glass; and generating, responsive to the input, a second instruction to a motor controller, the second instruction configured to cause the motor controller to adjust the position of a window covering associated with the glass. - View Dependent Claims (8, 9)

15. A method for controlling a glass having a variable characteristic, the method comprising:
-
using, by an automated shade control system, information related to at least one of solar penetration through a window or solar load on the window to establish a standard management routine for a glass having a variable characteristic; receiving, at the automated shade control system, reflectance information indicating the presence of calculated reflected light on the glass; and overriding, by the automated shade control system, the standard management routine responsive to the presence of calculated reflected light on the glass.
