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.

1. A method, comprising: receiving, at an automated shade control system, shadow information indicating the presence of calculated shadow on a window, wherein a window covering is associated with the window; andactivating, by the automated shade control system and responsive to the presence of the calculated shadow on the window, a motor associated with the window covering to position the window covering in a different position from the position specified by a standard management routine. 2. The method of claim 1, further comprising determining the duration of the calculated shadow on the window, wherein activating the motor is responsive to the duration exceeding a default shadow duration. 3. The method of claim 1, further comprising determining the duration of the calculated shadow on the window, wherein, responsive to the duration not exceeding a default shadow duration, the activating the motor is not performed. 4. The method of claim 1, wherein the motor is activated responsive to the automated shade control system determining the existence of a clear sky condition. 5. The method of claim 1, wherein, responsive to the automated shade control system determining the existence of an overcast sky condition, the activating the motor is not performed. 6. The method of claim 1, further comprising: receiving, by the automated shade control system, brightness information from a photometer associated with the window; andactivating the motor to adjust the window covering at least partially toward a fully closed position responsive to the brightness information exceeding a threshold value. 7. A method, comprising: receiving, at an automated shade control system, reflectance information indicating the presence of calculated reflected light on a window, wherein a window covering is associated with the window; andactivating, by the automated shade control system and responsive to the presence of calculated reflected light on the window, a motor associated with the window covering to position the window covering in a different position from the position specified by a standard management routine. 8. The method of claim 7, further comprising determining the duration of the calculated reflected light on the window, wherein activating the motor is responsive to the duration exceeding a default reflectance duration. 9. The method of claim 7, further comprising determining the duration of the calculated reflected light on the window, wherein, responsive to the duration not exceeding a default reflectance duration, the activating the motor is not performed. 10. The method of claim 7, wherein the motor is activated responsive to the automated shade control system determining the existence of a clear sky condition. 11. The method of claim 7, wherein, responsive to the automated shade control system determining the existence of an overcast sky condition, the activating the motor is not performed. 12. A method, comprising: calculating, by an automated shade control system and using a shadow model, the presence of calculated shadow at a location of interest, wherein the shadow model represents at least a portion of a building and at least a portion of the surroundings of the building; andactivating, by the automated shade control system, a motor to adjust a window covering responsive to the calculated shadow at the location of interest. 13. A method, comprising: calculating, by an automated shade control system and using a reflectance model, the presence of calculated reflected light at a location of interest, wherein the reflectance model represents at least a portion of a reflective surface; andactivating, by the automated shade control system, a motor to adjust a window covering responsive to the calculated reflected light at the location of interest. 14. The method of claim 13, wherein, responsive to the duration of the calculated reflected light at the location of interest not exceeding a default reflectance duration, the activating the motor is not performed. 15. The method of claim 13, further comprising using, by the automated shade control system, movement history information for the window covering to prevent the window covering from being moved for a limited period of time after the previous movement of the window covering. 16. The method of claim 13, wherein the activating the motor is performed responsive to a measured solar radiation value exceeding 60% of an ASHRAE theoretical clear sky solar radiation value. 17. A method, comprising: calculating, by an automated shade control system and using a reflectance model, the presence of calculated reflected light at a location of interest, wherein the reflectance model represents at least a portion of a building and at least a portion of the surroundings of a building; andcommunicating, by the automated shade control system and to a motor, a first movement request configured to adjust a window covering responsive to the calculated reflected light at the location of interest. 18. The method of claim 17, further comprising: receiving, at the automated shade control system, shadow information indicating the presence of calculated shadow at the location of interest; andcommunicating, by the automated shade control system and to the motor, a second movement request configured to adjust the window covering at least partially toward a fully closed position responsive to the reflectance information indicating the presence of calculated reflected light at the location of interest at the same time that the shadow information indicates the presence of calculated shadow at the location of interest. 19. An automated shade control system, comprising: a controller configured with a reflectance program,the controller configured to control, using reflectance information, a motor associated with a window. 20. The system of claim 19, wherein the reflectance information is obtained by using a reflectance model to calculate the presence of calculated reflected light on the window.
