60. Automated shading and dimming controls

Design features such as adjustable window shades and lights with dimmers must be actively managed to be effective. However, automated controls can help to ensure that these systems continually operate as intended and provide the designed benefits such as glare avoidance and energy reduction.

This feature requires automated control systems to ensure that window shades are effectively utilized to block glare from sunlight and that lighting controls are employed to limit artificial light output when sunlight is providing optimal light levels.

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 has the capacity and is programmed to dim continuously in response to daylight.
Part 2: Air Sanitization

Spaces with more than 10 occupants in buildings which recirculate air use one of the following technologies, either integrated within the central ventilation system or as a standalone device:

a.15 Ultraviolet germicidal irradiation.
b.15 Photocatalytic oxidation.
