6.1   Summary of Changes in 2013 Standards

6.1.1    Mandatory Changes

All luminaires rated for use with lamps greater than 150 watts shall comply with the uplight and glare maximum zonal lumen limits.

All outdoor lighting shall be controlled both by a photocontrol device or by an automatic scheduling control.  This is a change from 2008, when only a photocontrol was required.  Ann astronomical time-switch control that automatically turns the lights off during daylight hours is allowed as an alternative to a photocontrol device. All outdoor lighting is required to be circuited and independently controlled from other electric loads.

Outdoor luminaires mounted less than 24 feet above the ground are required to have controls (motion sensors or other systems) that are capable of reducing the lighting power of each luminaire by at least 40 percent but not exceeding 80 percent.  The luminaire must switch to its “on” state automatically when the space becomes occupied.

'In 'addition to the photocontrol and automatic scheduling controls described above, outdoor sales frontage, outdoor sales lots, and outdoor sales canopy lighting, controls are required that offer part-night control or have motion sensing capability to automatically reduce the lighting power by at least 40 percent but not more than 80 percent, and ability to automatically turn the lighting to ‘occupied’ light level when the space becomes occupied.

For building façade, ornamental hardscape, and outdoor dining, the same additional controls are required as for outdoor sales areas (above), but a centralized time-based zone lighting control that reduces lighting power by at least 50 percent is allowed as an alternative.

6.1.2    Prescriptive Changes

The general hardscape power allowances have been updated for Lighting Zone 1, 3 and 4. The additional lighting power allowances for specific applications have been updated for Building Entrances and Exits, Vehicle Service Station Canopies, and Outdoor Dining.

6.1.3    Additions and Alterations Changes

For alterations that do not increase connected lighting load, and in which 10 percent or more and less than 50 percent of the luminaires in a lighting application 'listed in Table 140.7-A or 140.7-B, only the altered luminaires are required to meet the applicable controls requirements of Sections 130.0, 130.2, and 130.4. The entire system is not required to meet Section 140.7, and LPD calculations are not required for the affected luminaires.

For alterations that replace more than 50 percent of the luminaires in a lighting application 'listed in Table 140.7-A or 140.7-B, all of the lighting in that application shall meet the applicable controls requirements of Sections 130.0, 130.2, 130.4, and 140.7.

Alterations that increase the connected lighting load in a lighting application 'listed in Table 140.7-A or 140.7-B require that the entire system in the application zone meet all the applicable requirements of Sections 130.0, 130.2, 130.4, and 140.7.
