The following lighting is exempt from all compliance and mandatory requirements:
Lighting within dwelling units. Not less than 75% of permanently installed light fixtures, other than low-voltage lighting, shall be fitted for, and contain only, high efficacy lamps.
At least one manual lighting control is required for each area enclosed by ceiling -height partitions. These controls can be any of the following:
a switch located so the occupant can see the area controlled by the switch
a switch that indicates whether the lights are on or off when it is impossible to see the controlled area from the switch location.
EXCEPTIONS:
areas designated as security or emergency areas that must be continuously lighted.
lighting in stairways or corridors that are elements of the means of egress.
Each area that requires manual controls must also have controls meeting requirements for automatic time switch devices, occupancy sensors, and daylight zone control.
EXCEPTIONS:
sleeping units
patient care spaces
spaces where an automatic shutoff would endanger occupant safety or security
lighting intended to operate continuously.
Automatic time switch control devices installed in all areas of the building and must include (EXCEPT emergency egress lighting):
an override switching device that:
is readily accessible
is located so the person using the device can see the lights or the area controlled by the switch, or so the area being lit is annunciated
permits manually operation
allows lighting to remain on for no more than 2 hours when an override is initiated
any individual override switch to control a maximum area of 5,000 ft2
EXCEPTIONS: Within malls, arcades, auditoriums, single tenant retail spaces, industrial facilities and arenas:
time limit can exceed 2 hours if captive key device and
area can be > 5,000 ft2 but can't be over 20,000 ft2
Occupant sensors to be installed in the following spaces and automatically turn lighting off within 30 minutes of all occupants leaving the space: classrooms, conference/meeting/training rooms, employee lunch and break rooms, private offices, storage/janitorial rooms, restrooms, and other spaces less than or equal to 300 ft2. Automatic-on sensors set power on < 50 percent power.
EXCEPTIONS: Full power automatic-on controls are permitted where manual-on operation would endanger the safety or security of the room or building occupants.
Daylight zones must have individual control of the lights independent of general area lighting, be controlled, and each daylight zone must be less than or equal to 2,500 ft2
Contiguous daylight zones adjacent to vertical fenestration can be controlled by a single controlling device if the zone doesn't include areas facing more than two adjacent orientations (i.e., north, east, south, west)
Daylight zones under skylights more than 15 feet from the perimeter must be controlled separately from daylight zones adjacent to vertical fenestration
EXCEPTION: Daylight spaces 1) enclosed by walls or ceiling-height partitions and 2) containing two or fewer light fixtures are not required to have a separate switch for general area lighting
Manual controls to be installed in daylight zone controls unless automatic controls are installed
Automatic daylight zone controls are:
capable of reducing power to less than 35% using continuous dimming ballasts and daylight-sensing controls OR
capable of automatic power reduction using step-dimming multi-level switching and daylight-sensing controls having at least two control channels per zone and at least one control step in the 50-70% range and another less than or equal to 35% of design power
Where required, general lighting in the daylight zone must be controlled by at least one multi-level control that reduces light in the space when daylight is available. Where daylit illuminance is greater than rated illuminance of the general lighting, the general lighting must be controlled so its power draw is 35 percent or less of its rated power. The multi-level control must be located so calibration and set point adjustment controls are readily accessible.
Separate control devices for
display/accent lighting
case lighting
task lighting
nonvisual lighting
under-shelf/cabinet lighting
lighting for sale
demonstration lighting
Hotel/motel sleeping units and guest suites have control device(s) at the entry door that control all permanent luminaires and switched receptacles
Sleeping Units: One or more master light switches are required at the entry door of sleeping units in hotels, motels, boarding houses or similar buildings. Master switches operate all permanently wired luminaires and switched receptacles. In multiple-room suites, the control can be at the entrance to each separate room or at the primary entry. EXCEPTION - Bathroom lighting.
Areas that require manual controls must allow the occupant to reduce the connected lighting load by at least 50 percent in a reasonably uniform illumination pattern. Lighting reduction requirements may be met by
controlling all lamps or luminaires
dual switching alternate rows of luminaires, alternate luminaires or alternate lamps
switching the middle lamp luminaires independently of the outer lamps
switching each luminaire or lamp.
EXCEPTIONS, light reduction controls not required if:
the area has only one luminaire with rated power less than 100 watts
an occupant-sensing device controls the area
the area is a corridor, equipment room, storeroom, restroom, public lobby, electrical or mechanical room, or sleeping unit
the space has a lighting power density less than 0.6 Watts per square feet
it's a daylight space that complies with Section C405.2.2.3.2
Astronomical time switch or a combination of a photosensor and a time switch control are required for all exterior lights not designated for dusk-to-dawn operation to turn off exterior lighting when sufficient day light is available or when the lighting is not required during night time hours. Astronomical time switch or photosensor control is required for lighting designated for dusk-to-dawn operation. All time switches shall be capable of retaining programming and the time setting during loss of power for a period of at least 10 hours.
The following types of one-lamp, three-lamp or odd-numbered lamp fluorescent fixtures must be tandem-wired:
pendant- or surface-mounted luminaires within 1 foot edge-to-edge of each other
recess-mounted luminaires located within 10 feet center-to-center of each other
Exception - luminaires
that use electronic high-frequency ballasts
on emergency circuits
with no available pair
Internally illuminated exit signs must not exceed 5 Watts per side.
The 2012 IECC permits fixtures used for the following purposes to be treated as exempt from inclusion in interior lighting power totals.
1. Connected power associated with the following lighting equipment is excluded in the calculation of total connected lighting power:
Professional sports arena playing field lighting
Sleeping unit lighting in hotels, motels, boarding houses or similar buildings
Emergency lighting automatically off during normal building operation
Lighting in spaces specifically designated for use by occupants with special lighting needs including the visually impaired and other medical and age-related issues

13. Lighting in retail display windows, provided the display area is enclosed by ceiling-height partitions
14. Furniture-mounted supplemental task lighting that is controlled by automatic shutoff
Screw lamp holder wattage is the maximum luminaire labeled wattage. Low-voltage lighting is the specified wattage of the supply transformer. Line voltage track lighting is either 1) specific wattage with minimum 30 W/linear ft OR 2) wattage limit of system's circuit breaker OR 3) wattage limit of other permanent current limiting devices.
Exterior lighting supplied through the building electrical service and not otherwise exempted must meet the following criteria:
All exterior building grounds luminaires that operate at greater than 100 watts shall contain lamps having a minimum efficacy of 60 lm/W unless the luminaire is controlled by a motion sensor or is otherwise exempted.
The total exterior lighting power allowance for all exterior building applications is the sum of the base site allowance plus the individual allowances for areas that are to be illuminated and are permitted in Table 505.6.2(2) for the applicable lighting zone. Tradeoffs are allowed only among exterior lighting applications listed in Table 505.6.2.(2), Tradable Surfaces section.
