Title 24 Lighting Control Acceptance Testing: Are the lighting controls ready for testing?
The California Energy Efficiency Standards commonly known as Title 24 requires that the lighting controls for indoor and outdoor lighting serving nonresidential buildings must be certified to meet the acceptance requirements for code compliance before an occupancy permit is granted. This means that a certified technician must performs lighting controls acceptance tests and complete documentation required for nonresidential buildings. This code requirement when into effect with the adoption of the 2013 code and was revised in 2016 code. The technician must complete the required Nonresidential Certificates of Acceptance (NRCA) shown on the drawings that typically include testing the automatic daylight controls, automatic daylighting controls, demand response controls, outdoor lighting controls, and for project under the 2016 code Institutional tuning power adjustment factor is a required. Often times the installing electrical contractor will need to consider the following items prior to acceptance testing of the lighting controls:
- Required Certificates: Check the plans to identify what Certificates of Acceptance (NRCA Forms) are listed. Verify that the correct Nonresidential Certificates of Acceptance shown on the NRCC LTI “Declaration of Required Certificates” are included in the design and shown on the drawings. Often times a Certificates of Acceptance will be required for a lighting control system that is not shown on the drawings and thus not installed.
- Installation Certificate (NRCI-LTI-01-E): Ensure that the Certificate of Installation is completed prior to commitment of acceptance testing by the installing contractor and provided to the certified acceptance testing technician.
- Installation Certificate (NRCI-LTI-01-E): Maintain the availability of the permit number, enforcement agency, and any documents related to occupancy permit.
- Automatic Time Switch Controls (NRCA-LTI-02-A): Be familiar with programming or viewing the time settings of the time switch and a programming document should available to access information on how to obtain the time switch settings.
- Type of Occupancy Sensors (NRCA-LTI-02-A): Describe the type of occupancy sensors (i.e. Occupancy, Partial Off, or Partial On) to the acceptance testing technician prior to testing.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Identify the drawing pages that show the daylit zones and light sensors or attach as-built drawings showing this information.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Be able to describe the dimming control type (i.e. Continuous, Stepped Dimming, or Switching) and control loop type: open or closed loop.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Identify the sensor location: outside, inside skylight, near windows facing out, or in controlled zone; and the location of control adjustments.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Confirm that daylighting controls installation manual and calibration instructions have been provided to building owner.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Provide necessary circuity information for luminaries controlled by automatic daylighting controls.
- Automatic Daylighting Controls (NRCA-LTI-03-A): Confirm that daylighting controls have been certified by in accordance with the California Energy Efficiency Standards by checking to see the device is listed at https://cacertappliances.energy.ca.gov
- Demand Response Lighting Controls (NRCA-LTI-04-A): Verify the demand responsive control is capable of receiving a demand response signal directly or indirectly through another device and that it complies with the requirements of the California Energy Efficiency Standards.
- Institutional Tuning Power Adjustment Factor (NRCA-LTI-05-A): Be familiar with the control or the methods of controlling the maximum output of the luminaries.
- Outdoor Lighting Controls (NRCA-LTO-02-A): Describe the type and location of control: motion sensor, photocontrol, or astronomical time-switch.
- Outdoor Lighting Controls (NRCA-LTO-02-A): Be familiar with programming or viewing the time settings of the time switch and a programming document should available to access information on how to obtain the time switch settings.
The Nonresidential Certificates of Acceptance are becoming increasingly required by code officials prior to final occupancy. Do not be caught off guard, become familiar with the acceptance testing requirements.
