Codes and Standards Enhancement (CASE) Report

The Statewide CASE Team is requesting feedback on the 2019 Title 24, Part 6 Draft CASE Reports. The CASE Report presents pertinent information that supports the code change proposal. Please email feedback to You may also submit written comments to the Energy Commission. See the agenda for Energy Commission pre-rulemaking workshop (available here) for instructions on how to submit comments to the Energy Commission’s docket.

Draft CASE Report: Nonresidential Outdoor Controls

Measure Description

The overall goals of this CASE Report are to propose code changes that clarify and streamline requirements, update definitions, and broaden the existing mandatory outdoor lighting controls requirements.

The Statewide CASE Team is proposing to remove the exception from the occupancy-based, bi-level/dimming control requirements for pole-mounted luminaires under 75 watts and proposing 30 watts as the new threshold for exemptions for all luminaires. Additionally, the proposed changes increase the lighting savings associated with bi-level lighting controls by dropping the range of required dimming from 40 to 90 percent diming to 50 to 90 percent dimming.

The Statewide CASE Team is also proposing to revise the language for occupancy-based, bi-level controls by establishing schedules of normally occupied and normally unoccupied times. The proposed code change also requires that scheduling controls, such as time clocks and part-night controls, be capable of partial lighting power reduction.

The proposed code change maintains the savings fraction associated with motion controls by limiting the wattage of luminaires from 1,500 watts to 400 watts that can be controlled together by an occupancy sensing system.

Finally, this CASE Report proposes changes to Section 141.0(b)2L Outdoor Lighting Alterations to clarify the existing language. This clarification does not change the stringency of the intent of this section.

Request for Feedback

The Statewide Utility Team encourages participation in the CASE Report development process through the submission of data—both primary sources and references to existing data. We are requesting data on areas such as energy savings, costs, market impacts, industry practices, barriers to code compliance, etc. from stakeholders. The data will inform the energy savings estimates, cost-effectiveness analysis, compliance and enforcement, and market impacts that will be presented in CASE Reports. Do you have feedback or data to share? Send us an email at
