Automated shading and dimming controls
Intent:
To prevent glare and encourage reliance on natural light through automated shading and dimming.
BACKGROUND
Design features such as adjustable window shades and lights with dimmers must be actively managed to be effective. Automated controls can help to ensure that these systems continually operate as intended and meet intended benefits such as glare avoidance and energy reduction. Furthermore, setting these features to automatically adjust can greatly contribute to comfort without disrupting occupants from other tasks.
The following requirements are met in all major workspace areas:
a.80
All lighting except decorative fixtures is programmed using occupancy sensors to automatically dim to 20% or less (or switch off) when the zone is unoccupied.
b.80
All lighting except decorative fixtures has the capacity and is programmed to dim continuously in response to daylight.
