Use the following steps to determine the interior lighting power allowance by the Building Area Method:
- Determine the appropriate building area type from Table 9.5.1 and the corresponding LPD allowance. For building area types not listed, selection of a reasonably equivalent type shall be permitted.
- Determine the gross lighted floor area in ft2 of the building area type.
- Multiply the gross lighted floor areas of the building area types times the LPD.
- The interior lighting power allowance for the building is the sum of the lighting power allowances of all building area types. Trade-offs among building area types are permitted, provided that the total installed interior lighting power does not exceed the interior lighting power allowance.
|Building Area Typea||LPD,W/ft2|
|Dining: Bar lounge/leisure||0.90|
|Dining: Cafeteria/fast food||0.79|
|Motion picture theater||0.83|
|Performing arts theater||1.18|
a. In cases where both a general building area type and a specific building area type are listed, the specific building area type shall apply.
- For each space enclosed by partitions that are 80% of the ceiling height or taller, determine the appropriate space type and the corresponding LPD allowance from Table 9.6.1. If a space has multiple functions, where more than one space type is applicable, that space shall be broken up into smaller subspaces, each using its own space type from Table 9.6.1. Any of these subspaces that are smaller in floor area than 20% of the original space and less than 1000 ft2 need not be broken out separately. Include the floor area of balconies and other projections in this calculation.
- In calculating the area of each space and subspace, the limits of the area are defined by the centerline of interior walls, the dividing line between subspaces, and the outside surface of exterior walls or semiexterior walls. For the purposes of this section, semiexterior walls that separate semiheated space from conditioned space shall be considered interior walls.
- Based on the space type selected for each space or subspace, determine the lighting power allowance of each space or subspace by multiplying the calculated area of the space or subspace by the appropriate LPD allowance determined in Section 9.6.1(a). For space types not listed, selection of a reasonable equivalent category shall be permitted.
- The interior lighting power allowance is the sum of lighting power allowances of all spaces and subspaces. Trade-offs among spaces and subspaces are permitted, provided that the total installed interior lighting power does not exceed the interior lighting power allowance.

An additional lighting power allowance shall be permitted for space types with nonmandatory controls installed as identified in Table 9.6.3 when all mandatory controls are used according to Section 9.4. This allowance is added to the interior lighting power allowance and is calculated as follows:
|Lighting Power Under Control||=||the total input watts of all lamps being controlled using the control method indicated|
|Control Factor||=||the value given in Table 9.6.3 for the corresponding space type and control method|
|Additional Control Method (in Addition to Mandatory Requirements)||Space Type|
|Open Office||Private Office||Conference Room, Meeting Room, Classroom (Lecture/Training)||Retail Sales Area||Lobby, Atrium, Dining Area, Corridors/Stairways, Gym/Pool, Mall Concourse, Parking Garage|
|Manual, continuous dimming control or programmable multilevel dimming control||0.05||0.05||0.10||0.10||0|
|Programmable multilevel dimming control using programmable time scheduling||0.05||0.05||0.10||0.10||0.10|
|Occupancy sensors controlling the downlight component of workstation specific luminaires with continuous dimming to off capabilities||0.25a||0||0||0||0|
|Occupancy sensors controlling the downlight component of workstation specific luminaires with continuous dimming to off operation, in combination with personal continuous dimming control of downlight illumination by workstation occupant||0.30a,b||0||0||0||0|
|Automatic continuous daylight dimming in secondary sidelighted areas||0.10c||0.10c||0.10c||0.10c||0.10c|
- Control factor is limited to workstation-specific luminaires in partitioned single occupant work spaces contained within an open office environment (i.e. direct-indirect luminaires with separately controlled downlight and uplight components, with the downward component providing illumination to a single occupant in an open plan workstation). Within 30 minutes of the occupant leaving the space, the downward component shall continuously dim to off over a minimum of two minutes. Upon the occupant entering the space, the downward component shall turn on at the minimum level and continuously raise the illumination to a preset level over a minimum of 30 seconds. The uplight component of workstation specific luminaire shall comply with Section 184.108.40.206(h) (automatic full off).
- In addition to the requirements described in footnote (a), the control shall allow the occupant to select their preferred light level via a personal computer, handheld device, or similarly accessible device located within the workstation.
- Control factors may not be used if controls are used to satisfy exceptions to Section 220.127.116.11.3
When using the Space-by-Space Method, an adjustment of the space LPD allowance is permitted for individual spaces where room cavity ratio (RCR) calculated for the empty room is documented to be greater than the RCR threshold for that space type shown in Table 9.6.1.
RCR = 2.5 × Room Cavity Height × Room Perimeter Length/Room Area
where Room Cavity Height = Luminaire Mounting Height — Workplane.
The following requirements are mandatory provisions and are necessary for compliance with this standard.
Construction documents shall require that within 90 days after the date of system acceptance, record drawings of the actual installation be provided to the building owner or the designated representative of the building owner. Record drawings shall include, as a minimum, the location, luminaire identifier, control, and circuiting for each piece of lighting equipment.
Construction documents shall require for all lighting equipment and lighting controls that an operating manual and maintenance manual be provided to the building owner or the designated representative of the building owner within 90 days after the date of system acceptance. These manuals shall include, at a minimum, the following:
- Submittal data indicating all selected options for each piece of lighting equipment, including but not limited to lamps, ballasts, drivers, and lighting controls.
- Operation and maintenance manuals for each piece of lighting equipment and lighting controls with routine maintenance clearly identified including, as a minimum, a recommended relamping/cleaning program and a schedule for inspecting and recalibrating all lighting controls.
- A complete narrative of how each lighting control system is intended to operate, including recommended settings.
