Automated shade control in connection with electrochromic glass

A system, comprising:

• a glass controller configured to adjust a variable characteristic of a glass;
• a central controller configured to control the glass controller and a motor associated with a window covering;
• the motor associated with the window covering;
• and
• at least one of a radiometer or a photometer to detect at least one of lighting information or radiation information.

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.

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.

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 reflectance model;
• using, by the automated shade control system, the reflectance model a first time to calculate the presence of calculated reflected light at the first location of interest;
• and
• communicating, to a first glass controller, a first instruction configured to adjust a variable characteristic of a first glass responsive to the calculated reflected light at the first location of interest.

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.
