Codes and Standards Enhancement (CASE) Report

The Statewide CASE Team 2019 Title 24, Part 6 Final CASE Report is available below. The Final CASE Report incorporates feedback received during utility-sponsored stakeholder meetings, Energy Commission Pre-Rulemaking workshops, and personal communication with stakeholders. We encourage stakeholders to email feedback on the Final CASE Report to You can also participate in the 2019 Title 24, Part 6 Standards updated by attending the Energy Commission workshops and submitting written comments to the rulemaking docket. Refer to the Pre-Rulemaking and Rulemaking Workshop Notices for instructions on how to submit comments to the Energy Commission’s docket (available here).

Measure Description

This proposed code change is an update to lighting power allowances (LPAs) for all outdoor applications. It saves energy by extending the use of high efficacy light emitting diode (LED) technology as the basis for LPA calculations for all outdoor areas (Table 140.7-A and Table 140.7-B), which reduces LPAs. The proposed LPAs can be met with warm correlated color temperature (3000K) light sources. The Statewide CASE Team ensured that the LPAs can be met by 3000K fixtures because there has been a shift in outdoor lighting design towards warmer correlated color temperature in recent years and many local governments have installed warm correlated color temperature outdoor fixtures (3000K to 4000K). The Statewide CASE Team has not observed any significant momentum towards installations below 3000K. Table 140.7-A (General Hardscape) was updated based on LED performance levels during the 2016 code cycle, however, most changes to Table 140.7-B (Specific Applications) were rejected due to the individual line items not being cost-effective. LED efficacy has continued to grow and costs have continued to drop; all line items in Table 140.7-B are now cost-effective.

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.
