SKY CAMERA SYSTEM FOR ANALYZING CLOUD CONDITIONS

摘要

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.
