Abstract

Systems, methods, and apparatuses for coordinating and controlling a building automation system (such as building HVAC system) and a building shading system so as to provide efficient energy management and other benefits are provided.

Claims

1. A method for determining an active shading strategy within a building automation system, the method comprising:

providing a building HVAC system;

providing a building shading system;

determining an energy efficiency position for one or more shades of the building shading system;

determining a glare protection position for the one or more shades of the building shading system;

determining a shading strategy configuration for the one or more shades of the building shading system;

determining a room operating mode of a room controlled by the building HVAC system; and

determining an optimal active shading strategy as a result from the shading strategy configuration and the room operating mode.

2. The method of claim 1, wherein the room operating mode is determined to be comfort, the shading strategy configuration is determined to be maximum comfort, and the optimal active shading strategy is determined to be glare protection.

3. The method of claim 1, wherein the room operating mode is determined to be comfort, the shading strategy configuration is determined to be comfort oriented, and the optimal active shading strategy is determined to be glare protection.
