Lighting - General Requirements
<br />1513 Lighting Controls: Lighting, including exempt lighting
<br />in Section 1512. shall comply with this snclion. Where
<br />occupancy sensors are cited, they shall have the features
<br />listed it, Section 1513.6.1. Where automatic tame switches
<br />are cited, they shall have the features listerl ;n Section
<br />1513.6.2.
<br />1513.1 LOCI.1 Control and Accessibility: Each space.
<br />enclosed by walls or ceiling -height pi- titlons, shall be
<br />provided with lighting controls locnied within that space. The
<br />lighting controls, whether one or more, shall be capable of
<br />turning off all lights within the space. The controls shall be
<br />readily accessible, at the point of entry/exit, to personnel
<br />occupying or using the space.
<br />EXCEPTIONS: The following lighting controls may be
<br />centralized in remote locations:
<br />1. Lighting controls for spaces which must be used as
<br />a whole.
<br />2. Automatic controls.
<br />3. Controls requiring trained operators.
<br />4. Controls for safety hazards and security.
<br />1513.2 Area Controls: The maximum lighting power that
<br />may be controlled from a single switch or automatic control
<br />shall not exceed that which Is provided by a 20 ampere circuit
<br />loaded to not more than 80 %. A master control may be
<br />installed provided the individual switches retain their capability
<br />to function independently. Circuit breakers may not be used
<br />as the sole means of switching.
<br />EXCEPTIONS: 1. Industrial or manufacturing process
<br />areas, as may be required for production.
<br />2. Areas less than 5% of the building footprint for
<br />footprints over 100.000 ft2.
<br />1513.3 Daylight Zone Control: All daylighted zones, as
<br />defined in Chapter 2, both under overhead glazing and
<br />adjacent to vertical glazing, shall be provided with individual
<br />controls, o: daylight- or occupant_sensing automatic controls,
<br />which control the lights Independent of general area lighting.
<br />Contiguous daylight zones adjacent to vertical glazing are
<br />allowed to be controlled by a single controlling device
<br />provided that they do not include zones facing more than two
<br />adjacent cardinal orientations (i.e. north, east, south, west).
<br />Daylight zones under overhead glazing more than 15 feel
<br />from the perimeter shall be controlled separately from daylight
<br />zones adjacent to vertical glazing.
<br />EXCEPTION: Daylight spaces enclosed by walls or
<br />ceiling height partitions and containing 2 or fewer light
<br />fixtures are not required to have a separate switch for
<br />general area lighting.
<br />1513.4 Display, Exhibition and Specialty Lighting
<br />Controls: All display, exhibition or specialty lighting shall be
<br />controlled independently of general area lighting.
<br />1513.5 Automatic Shut-off Controls, Exterior: Lighting for
<br />all exterior applications shall have automatic controls capable
<br />of turning off exterior l,ghting when sufficient daylight is
<br />available or when the lighting is not required during nighttime
<br />hours. Lighting not designated for dusk -to -dawn operation
<br />shall be controlled by either:
<br />a. A combination of a photosensor and a time switch;
<br />or
<br />b. An astronomical time switch.
<br />Lighting designated for dusk -to -dawn operation shall be
<br />controlled by an astro,lomicai time switch or pholosensor. All
<br />time switches shall he capa!)le of retaining programming and
<br />the time setting during loss of power for a period of at least 10
<br />hours.
<br />EXCEPTION: Lighting for covered vehicle entrances
<br />or exits from buildings or parking structures where
<br />required for safety. security. or eye adaptation.
<br />1513.6 Automatic Shut -Off Controls, Interior: Buildings
<br />greater than 5,000 f12 and all school classrooms shall be
<br />equipped with separate automatic controls to shut off the
<br />lighting during unoccupied hours. Within these buildings, all
<br />office areas less than 300 112 enclosed by walls or ceiling -
<br />height partitions, and all meeting and conference rooms, and
<br />all school classrooms, shall be equipped with occupancy
<br />sensors that comply with Section 1513.6.1. For other spaces.
<br />automatic controls may be an occupancy sensor, time switch
<br />or other device capable of automatically shutting off lighting.
<br />EXCEPTIONS: 1. Areas that must be continuously
<br />illuminated (e.g„ 24-hour convenience stores), or
<br />illuminated in a manner requiring manual opc,auun ..,
<br />the lighting.
<br />2. Emergency lighting systems.
<br />3. Switching for industrial or manufacturing process
<br />facilities as may be required for production.
<br />4. Hospitals and laboratory spaces.
<br />5. Areas in which medical or dental tasks are
<br />performed are exempt from the occupancy sensor
<br />requirement.
<br />1613.6.1 Occupancy Sensors: Occupancy sensors shall
<br />be capable of automatically turning off all the hghts in an
<br />area, no more than 30 minutes after the area he s been
<br />vacated.
<br />Light fixtures controlled by occupancy sensors shall have a
<br />wall -mounted, manual switch capable of turning off lights
<br />when the space is occupied.
<br />EXCEPTION: Occupancy sensors in stairwells are
<br />allowed to have two step lighting (high -light at I low -
<br />light) provided the control fails in the high -light position.
<br />1513.6.2 Automatic Time Switches: Automatic time
<br />switches shall have a minimum 7 day clock and be capable
<br />of being set for 7 different day types per week and
<br />incorporate an automatic holiday "shut-off' feature, which
<br />tums off all loads for at least 24 hours and then resumes
<br />normally scheduled operations. Automatic time switches
<br />shall also have program back-up capabilities, which prevent
<br />the loss of program and time settings for at least 10 hours, if
<br />power is interrupted.
<br />Automatic time switches shall incorporate an over -ride
<br />switching device which:
<br />a. is readily accessible;
<br />b. is located so that a person using the device can see the
<br />lights or the areas controlled by the switch, or so that the
<br />area being illuminated is annunciated;
<br />c. is manually operated;
<br />d. allows the lighting to remain on for no more than 2 hours
<br />when an over -ride is initiated; and
<br />e. controls an area not exceeding 5.000 ft' or 5% of the
<br />building footprint for footprints over 100,000 It, whichever is
<br />greater.
<br />1513.7 Commissioning Requirements: For lighting
<br />controls which include daylight or occupant sensing
<br />automatic controls, automatic shut-off controls, occupancy
<br />sensors, or automatic time switches, the lighting controls
<br />shall be tested to ensure that control devices, components,
<br />equipment and systems are calibrated, adjusted and operate
<br />In accordance with approved plans and specifications.
<br />Sequences of operation shall be functionally tested to
<br />ensure they operate in accordance with approved plans and
<br />specifications. A complete report of test procedures and
<br />results shall be prepared and filed with the owner. Drawing
<br />notes shall require commissioning in accordance with this
<br />paragraph.
<br />1514 Exit Signs: Exit signs shall have an input power
<br />demand of 5 Watts or less per sign.
<br />Motors - General Requirements
<br />1511 Electric Motors: All permanently wired polyphase
<br />motors of 1 hp or more, which are not part of an HVAC
<br />system, shall comply with Section 1437.
<br />EXCEPTIONS: 1. Motors that are an Integral part of
<br />specialized process equipment.
<br />2. Where the motor is integral to a listed piece of
<br />equipment for which no complying motor has been
<br />approved.
<br />Transformers - General Requirements
<br />SECTION 1540 —TRANSFORMERS
<br />The minimum efficiency of a low voltage dry -type
<br />distribution transformer shall be the Class 1 Efficiency Levels
<br />for distribution transformers specified in Table 4-2 of the
<br />"Guide for Determining Energy Efficiency for Distribution
<br />Transformers" published by the National Electrical
<br />Manufacturers Association (NEMA TP-1-2002).
