Interior Lighting Automatic Lighting Shutoff – ASHRAE 90.1 Section 9.4.1.1
Time clock or occupancy sensors.
Required for all lighting not needed for 24-hour operation or occupant safety.
Manual on or automatic on to 50% power. Except: corridors and stairwells restrooms entrance areas and lobbies Automatic off requirement after 30 minutes in many spaces.

Interior Lighting Space Control – ASHRAE 90.1 Section 9.4.1.2
Each space to have at least one control device. Step control required. After hours override required for a minimum of two hours. June 4, 2014 AOBA / Current Trends in Sustainability
7
Interior Lighting Daylighting Controls – ASHRAE 90.1 Section 9.4.1.4 & 9.4.1.5
Photosensor control required for daylight areas.
Side daylighting with windows Overhead daylighting with skylights and roof monitors Step control required. Exceptions only where exterior obstructions are present.

Parking Garage Lighting Controls – ASHRAE 90.1 Section 9.4.1.3
Reduction of power by minimum of 30% with 30 minutes of inactivity.
Zones less than 3600SF. Daylight transition lighting.
Photosensors required within 20’ of perimeter walls with 40% opening. AOBA / Current Trends in Sustainability

Exterior Lighting Controls – ASHRAE 90.1 Section 9.4.1.7
Exterior lighting to be automatically turned off with presence of daylight. All building and façade lighting to be shut off at night. Between 12am and 6am, unless operating hours extend into this time. Any additional exterior lighting to be reduced to 30% output. June 4, 2014 AOBA / Current Trends in Sustainability
