Abstract
Intelligent building control systems utilize sky information from a camera or cameras to facilitate control of building systems such as lighting, motorized window coverings, electrochromic glazings, HVAC systems, and so forth. Based on the sky information, interior lighting intensity and/or color temperature may be modified, for example in order to achieve a desired circadian effect for building occupants. In this manner, energy efficiency and occupant comfort and convenience are improved.
Claims20
A system comprising:
- a processor;
- and
- a tangible, non-transitory memory configured to communicate with the processor,
- the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising:
- predicting, by the processor and utilizing a camera image of a sky, a predicted circadian impact associated with a location of interest, in advance of the circadian impact impacting the location of interest;
- and
- performing, by the processor, at least one of:
- (i) communicating, to a building management system, information regarding the predicted circadian impact at the location of interest in advance of the circadian impact impacting the location of interest,
- (ii) causing an adjustment of a window shade associated with the location of interest in advance of the circadian impact impacting the location of interest,
- (iii) causing activation of a glass controller to adjust a variable characteristic of a glass associated with the location of interest in advance of the circadian impact impacting the location of interest,
- (iv) communicating, to a lighting control system, information regarding the predicted circadian impact at the location of interest in advance of the circadian impact impacting the location of interest, or
- (v) causing an adjustment of a lighting fixture associated with the location of interest in advance of the circadian impact impacting the location of interest.
