ICONOGRAPHY GUIDE: Luminaires and ControlsHigh EfficacyLED LuminaireFor the purpose of Title 24 compliance in residential projects a luminairecan be certified as High Efficacy by meeting performance requirements.High efficacy luminaires differ by technology. Some examples are: LEDluminaries must meet Joint Appendix 8 (JA8) and certified to CaliforniaTitle 20 Appliance Database, CFL residential recessed luminaries mustcontain CFL ballast that are certified to California Title 20 ApplianceDatabase meeting select efficacy requirement, and residentialfluorescent luminaires containing fluorescent ballasts that are certifiedto California Title 20 Appliance Database.In order for residential LED luminaires to be classified as High Efficacythey must meet Joint Appendix 8 (JA8) and be certified to the CaliforniaTitle 20 Appliance Database. Residential compliance includes singlefamily homes, hotel/motel guest rooms, high-rise apartment livingspaces, dormitory rooms, senior living facility quarters, etc.; all of whichare considered generically “dwelling” spaces.References: Tables 150.0-A and 150.0-B; Section 150.0(k), 150.2(b),110.9(e), 100.0(h)References: Tables 150.0-A, 150.0-B; Sections 100.0(h), 110.9(e),110.10(b), 130.1(c), 150.0(k), 150.2(b), 110.9(f)Fluorescent Luminairew/ BallastResidential RecessedLuminaires w/ BallastIn Title 24 Residential and Nonresidential compliance, fluorescentluminaires must include ballasts that are certified to the California Title20 Appliance Database. While 4-pin electronic fluorescent is generallyviewed as a compliant device, the ballast installed must be certified tothe California Title 20 Appliance Database. In order to be certified, theballast must meet all Title 20 requirements.Fluorescent ballasts certified to the California Title 20 ApplianceDatabase for use within a residential recessed luminaire would beclassified as High Efficacy. Requirements to use high-efficacy devicesare found in single family homes, hotel/motel guest rooms, high-riseapartment living spaces, dormitory rooms, senior living facility quarters,etc.; all of which are considered “dwellings”.References: Tables 130.1-A, 150.0-A; Sections 100.0(h), 110.1References: Table 150.0-A, 150.0-B; Sections 100.0(h), 110.1, 110.9(f)Luminaire DimmingExitLuminaireTitle 24 Nonresidential indoor compliances utilize dimming luminairesfor requirements such as demand response, multi-level dimmingand daylighting. Power adjustment factors that lower claimed LPDlevels can be earned when select controls strategies are applied.Nonresidential outdoor compliance strategies utilize dimmingluminaires during periods where the area is vacant. Part-night lightingcontrol and centralized time-based zone control may also includedimming as part of an energy use reduction plan.References: Tables 130.1-A and 140.6-A; Sections 130.1(b), 130.1(c),130.1(d), 130.1(e), 130.2(c), 140.6(a)(2)Emergency Back-up(For Egress)Emergency back-up circuits are commonly used in the design of lifesafety systems such as lighting to meet the code requirements forsafety and noted in Title 24 as low power consumption circuits shownon the design plans.References: Sections 130.1(a), 130.1(c), 140.6(a), 140.6(c), 150.0(k)6EATONTitle 24 Guidelines (2013 Standards)Only Emergency Exits luminaires certified to the California Title 20Appliance Database can be used for Title 24 compliance. This doesnot include egress luminaires but those that provide egress signagesuch as “EXIT”, illuminated 24 hours a day and 365 days a year.References: Sections 140.6(a), 140.8(b)

ICONOGRAPHY GUIDE: Functional RequirementsReportingMonitoringFor use in commissioning, reports can be provided from the energymanagement system to demonstrate performance for lighting loads,electrical distribution system results, branch circuit measurements,control impact, demand response, daylighting performance, and showwhere adjustments were made. The ability to report results fromcommissioning are required for building owner for buildings over 10,000square feet.An Energy Management Systems (EMS) is a computerized controlsystem designed to regulate the energy consumption of a building bycontrolling the operation of energy consuming systems, such as theheating, ventilation and air conditioning (HVAC), lighting, and waterheating systems, and is capable of monitoring environmental andsystem loads, and adjusting HVAC operations in order to optimizeenergy usage and respond to demand response signals.Reference: Sections 120.8(a), 120.8(i), 130.1(d), 130.1(e)Reference: Sections 120.8(a), 120.8(i)Vacancy SensorManual On/Auto OffDaylightingControlA manual ON with automatic off control, commonly called “vacancysensors”, can be used to in lieu of occupancy sensors especiallywhen short periods of occupancy occur and the lighting is not neededfor the short period. Title 24 limits the amount of time a space is litwhen a space is not occupied and requires in spaces like offices andconference rooms mandatory controls to turn off a the space whenunoccupied.Title 24 in Nonresidential Indoor compliance mandates daylightingcontrols where there are skylit and sidelit zones. In the case of sidelitzones, where there are 24 square feet of glazing inside buildings and 36square feet of openings or glazing for parking garages. Sidelit zones areseparated in primary and secondary zones. Self-contained sensors mustbe certified to California Title 20 Appliance Database while daylightingsystems must be certified by approved technicians.References: Sections 110.9(a), 110.9(b), 110.10(b), 141.0(b), 150.0(k)References: Tables 141.0-E, 141.0-F; Sections 110.9(a), 110.9(b),130.1(b), 130.1(d), 140.3(c), 140.6(d)DemandResponseOccupancySensorTitle 24 requires that buildings larger than 10,000 square feet havedemand responsive lighting controls capable of delivering a minimumof 15% reduction in lighting load in a uniform method. In the case ofaltered or remodeled spaces, the 10,000 square feet applies to the areamodified.The automatic on and off feature of the occupancy sensor adjusts thelighting load based upon the space’s activity. Title 24 code deploys thisfunctionality as mandatory reducing or turning off power in residential,nonresidential indoor and outdoor compliance requirements. It is alsoincluded to as a power adjustment factor to reduce installed lightingloads to meet the lighting power budgets.References: Tables 130.1-A, 140.6-A, 141.0-E, 141.0-F; Sections110.9(a), 110.10(b), 130.1(b), 130.1(e), 130.3(a), 140.6(a), 141.0(b),References: Tables 140.6-A, 141.0-E, 141.0-F; Sections 110.9(a),110.9(b), 130.1(c), 130.2(c), 130.5(d), 140.6(a), 141.0(b), 150.0(k)ManualDimmerManually SwitchedON/OFFIn nonresidential compliance, continuous dimming is required for certainluminaires such as LED, see TABLE 130.1-A; a manual dimmer is onemethod to satisfy requirements of 130.1(b). Manual dimmers are alsoa part of the power adjustment factor(PAF) offering that can reduceprescriptive lighting power densities(LPD). Residential complianceutilizes dimmers in some spaces when “low efficacy” luminaires areallowed.Title 24 requires that a manual switch control with ON/OFF be providedfor each area enclosed by ceiling-height partitions. There are someexceptions including large areas including malls, sales floors, industrialfacilities, and larger public restrooms. The manual switch must beaccessible within the same room and lighting types such as generallighting and display lighting must be separately circuited. When otherlighting controls are included such as a manual dimmer, the ON/OFFfunctionality cannot be bypassed.References: Tables 130.1-A, 140.6-A, 141.0-E, 141.0-F; Sections110.9(b), 130.1(a), 130.1(b), 130.3(a), 140.6(a), 141.0(b), 150.0(k)References: Tables 141.0-E, 141.0-F; Sections 110.9(a), 110.9(b),130.1(a), 130.1(b), 130.1(c), 141.0(b), 150.0(k)EATONTitle 24 Guidelines (2013 Standards)7

ICONOGRAPHY GUIDE: ConstraintsLighting PowerDensitySquare FootageRangeIn nonresidential compliance, once mandatory requirements aresatisfied, lighting power density(LPD) allowances must be satisfied.The evaluation can be done through one of three ways; Prescriptive,Performance or Tailored. Prescriptive is the simplest and can be done atthe building or space level. Be aware that the luminaries power can bereduced by a power adjustment factor (PAF) when coupled with certaincontrols that are not part of the Mandatory Requirements. The TailoredMethod uses target illuminance values and calculated based upon thecavity ratio to determine LPD for general lighting and allows for additionalallowances for ornamental, wall display, etc. The Performance Methodcombines measures based upon Time Dependent Valuation (TDV).Title 24 utilizes the area of a space to determine when to applythe mandatory requirements. Some examples include office size,controlled space, cumulative permitted work area for DemandResponse, etc.References: Tables 140.6-A, 140.6-B, 140.6-C, 140.6-G; Sections130.1(d), 130.1(e), 140.3(c), 140.6(a), 140.6(b), 140.6(c),Daylight OpeningTitle 24 uses the total opening area in square feet within a buildingand parking structure determine the need for daylighting controls. Theopening in a parking structure can be glazing or an opening and thestarting point is 36 square feet. For the inside of a building, the glazingstarting point is 24 square feet.BUG / Zonal LumenRequirementsTitle 24 outdoor requirements for luminaires rated greater than 150watts are required to meet the zonal lumen requirements.References: Tables 130.2-A, 130.2-B; Sections 130.2(b)References: Section 130.1(d)Maximum WattageControlled TogetherTitle 24 requirement establishes the maximum wattage that can becontrolled together to apply the mandatory requirements.References: Sections 130.1(c), 130.2(c)Height of Luminairefor OutdoorIn nonresidential outdoor compliance the luminaire height willdetermine what Mandatory Measures have to be implemented to meetTitle 24 requirements. When luminaries mounted 24 feet or below,automatic lighting control is required to minimize power consumptionwhen unoccupied.References: Sections 130.2(c)24/7OperationUnder Title 24, there are many conditions/constraints imposedwhere 24 hours a day and 365 days a year provide exemptionsto the mandatory use of controls such as emergency egress andtunnel lighting.Reference: Sections 130.1(c), 130.2(c), 130.3(a)EATONTitle 24 Guidelines (2013 Standards)9
