60. Automated shading and dimming controls

Intent: 

To prevent glare and encourage reliance on natural light through automated shading and dimming.

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.

Part 1: Automated Sunlight Control

All windows larger than 0.55 m² [6 ft²] have the following:

a.80 Shading devices that automatically engage when light sensors indicate that sunlight could contribute to glare at workstations and other seating areas.
Part 2: Responsive Light Control

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.
