1. A method comprising:
- receiving, at an automated shade control system, shadow information indicating the presence of a calculated shadow at a first location of interest; and
communicating, to a first motor, a first movement request configured to adjust a first window covering responsive to the calculated shadow at the first location of interest,wherein the receiving comprises;
modeling, by the 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; and
querying, 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.

Abstract
Automated shade systems 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, 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.

13. A method for controlling a window covering, the method comprising:
-
receiving, at an automated shade control system, shadow information indicating the presence of a calculated shadow at a first location of interest; communicating, to a first motor, a first movement request configured to adjust a first window covering responsive to the calculated shadow at the first location of interest; and receiving, at the automated shade control system, reflectance information indicating the presence of calculated reflected light at the first location of interest. - View Dependent Claims (14)

15. A method for controlling a window covering, the method comprising:
-
receiving, at an automated shade control system, shadow information indicating the presence of a calculated shadow at a first location of interest; communicating, to a first motor, a first movement request configured to adjust a first window covering responsive to the calculated shadow at the first location of interest; using a reflectance model to calculate the presence of calculated reflected light at the first location of interest; and communicating, to the first motor, a second movement request configured to adjust a first window covering at least partially toward a fully closed position responsive to the reflectance model indicating the presence of calculated reflected light at the first location of interest at the same time that the shadow model indicates the presence of calculated shadow at the first location of interest.

16. A method for controlling a window covering, the method comprising:
-
receiving, at an automated shade control system, shadow information indicating the presence of a calculated shadow at a first location of interest; and communicating, to a first motor, a first movement request configured to adjust a first window covering responsive to the calculated shadow at the first location of interest, wherein the first movement request is communicated to the first motor responsive to the automated shade control system determining the existence of a clear sky condition.

17. A method for controlling a window covering, the method comprising:
-
receiving, at an automated shade control system, shadow information indicating the presence of a calculated shadow at a first location of interest; and communicating, to a first motor, a first movement request configured to adjust a first window covering responsive to the calculated shadow at the first location of interest, wherein, responsive to the automated shade control system determining the existence of a cloudy sky condition, the first movement request is not communicated to the first motor.
