Automated shade control system interaction with building management system
First Claim
1. A method, comprising:
- modeling, by an automated 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 control system, the shadow model to calculate the presence of calculated shadow at a location of interest;
communicating, by the automated control system and to a building management system, the information regarding the presence of calculated shadow at the location of interest,wherein the building management system adjusts interior environment settings associated with the location of interest based on the information regarding the presence of calculated shadow at the 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. Modeled brightness information may be utilized to control shades.

23. A method, comprising:
-
receiving, at a building management system and from an automated control system, information regarding the presence of calculated shadow at a location of interest; and adjusting, by the building management system, interior environment settings associated with the location of interest based on information regarding the presence of calculated shadow at the location of interest, wherein the information regarding the presence of calculated shadow at a location of interest was created by the automated control system by; modeling, by the automated 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 using, by the automated control system, the shadow model to calculate the presence of calculated shadow at the location of interest.
