Automated shade control in connection with electrochromic glass
First Claim
1. A system, comprising:
- a motor configured to actuate a window covering;
a glass controller configured to adjust a variable characteristic of a glass; and
a central controller configured to control the motor and the glass controller,wherein the central controller utilizes a proactive algorithm, andwherein the proactive algorithm is configured to utilize at least one of lighting information, radiation information, brightness information, or solar heat gain to calculate a total foot-candle load on a structure.

Abstract
Automated shade systems may comprise motorized window coverings, sensors, and controllers that use algorithms to control operation of the automated shade control system. 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, ASHRAE 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.
