Connection to other automatic shut-off controls is not required for these spaces.

Automatic Shut-off
Interior lighting in buildings will be controlled with an automatic control device to shut off building lighting in all spaces.
Applies to buildings larger than 5,000 ft2 (464 m2). The device can be:
Timeclock control device (an independent program schedule will be provided for areas no more than 25,000 ft2 (2,323 m2) but not more than 1 floor)
Occupancy sensor that turns off lighting within 30 minutes of an occupant leaving a space
A signal from another control or alarm system that indicates when an area is unoccupied
Exceptions:
Lighting intended for 24-hour operation
Lighting in spaces where patient care is rendered
Lighting in spaces where an automatic shut-off would endanger the safety or security of occupants

Daylighting
Lighting power will be reduced in areas where daylight can help illuminate the space.
Proposed Requirements for 2010
Specific daylit areas must be separately controlled by at least 1 multi-level photocontrol (including continuous dimming devices) that have the following characteristics:
Light sensors for the photocontrol will be remote from where calibration adjustments are made
Calibration adjustments will be readily accessible
The multi-level photocontrol will reduce electric lighting in response to available daylight with at least one control step that is between 50 – 70% of design lighting power and another control step that is no greater than 35% of design power

Exterior Lighting Control
Lighting for most exterior applications will have automatic controls capable of turning off exterior lighting when sufficient daylight is available or when the lighting is not required during nighttime hours.
Lighting not designated for dusk-to-dawn operation will be controlled by:
Combination of a photosensor and a timeclock device
Astronomical timeclock device
Lighting designated for dusk-to-dawn operation will be controlled by an astronomical timeclock device or photosensor.
All timeclock devices will be capable of retaining programming and time setting during loss of power for a period of at least 10 hours.
Exception:
Lighting for covered vehicle entrances or exits from buildings or parking structures where lighting is required for safety, security, or eye adaptation.


Optional Control Incentives
The ASHRAE/ IESNA Standard contains optional lighting incentives that can be satisfied by the following:
Multi-level occupancy sensor (5% increase in Lighting Power Density [LPD])
Manual dimming or programmable multi-scene dimming (5 –10% increase in LPD)
Automatic daylighting controls where not required (10 – 20% increase in LPD depending on effective aperture and LPD requirement)above information from http://www.lutron.com
