• § 130.1 Medium relevance — show source text

  C. The daylight responsive controls shall meet the following: i. For spaces where the installation of multilevel lighting controls is required under Section 130.1(b), allow the multilevel lighting controls to adjust the light level with continuous dimming; ii. For each space, ensure the combined illuminance from the controlled lighting and daylight is not less than the illuminance from controlled lighting when no daylight is available; iii. For areas other than parking garages, ensure that, when the daylight illuminance is greater than 150 percent of the illuminance provided by the controlled lighting when no daylight is available, the controlled lighting power in that daylight zone shall be reduced by a minimum of 90 percent; and iv. For parking garages, ensure that when daylight illuminance levels measured at the farthest edge of the secondary sidelit zone away from the glazing or opening are greater than 150 percent of the illuminance provided by the controlled lighting when no daylight is available, the controlled lighting power in the combined primary and secondary sidelit daylit zones shall be reduced by 100 percent; and D. Photosensors shall be located so that they are not readily accessible to unauthorized personnel; and E. The location where calibration adjustments are made to the daylight responsive controls shall be readily accessible to authorized personnel but may be inside a locked case or under a cover which requires a tool for access; and F. The automatic daylighting control shall permit the multilevel lighting control to adjust the level of lighting.

  Exception 1 to Section 130.1(d): Areas under skylights where it is documented that existing adjacent structures or natural objects block direct sunlight for more than 1,500 daytime hours per year between 8 a.m. and 4 p.m.

  Exception 2 to Section 130.1(d): Areas adjacent to vertical glazing below an overhang, where the overhang covers the entire width of the vertical glazing, no vertical glazing is above the overhang, and the ratio of the overhang projection to the overhang rise is greater than 1.5 for south, east and west orientations or greater than 1 for north orientations.

  Exception 3 to Section 130.1(d): Where daylight responsive controls are not required for the primary sidelit daylit zones, and where the total wattage of general lighting luminaires in the secondary sidelit daylit zones is less than 85 watts, daylight responsive controls are not required for the secondary sidelit zone.

  Exception 4 to Section 130.1(d): Reserved.

  Exception 5 to Section 130.1(d): Rooms that have a total glazing area of less than 24 square feet, or parking garage areas with a combined total of less than 36 square feet of glazing or opening.

  Exception 6 to Section 130.1(d): For parking garages, luminaires located in the daylight adaptation zone.

  Exception 7 to Section 130.1(d): Luminaires in sidelit daylit zones in retail merchandise sales and wholesale showroom areas.

  (e) Demand responsive controls. See Section 110.12 for requirements for demand responsive lighting controls.

  (f) Occupancy sensing controls interactions with space-conditioning systems. For space-conditioning system zones serving only spaces that are required to have occupant sensing controls as specified in Sections 130.1(c)5 and 6, and where Table 120.1-A allows the ventilation air to be reduced to zero when the space is in occupied-standby mode, the space-conditioning system shall be permitted to be controlled by occupancy sensing controls as specified in Section 120.2(e)3.
