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 email@example.com. 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.
This proposal will update the required lighting power density (LPD) values for indoor lighting to reflect the increased efficacy and increased optical control associated with light emitting diode (LED) technology. The recommended revisions will modify the allowed lighting power for all three calculation methods:
- Complete Building Method
- Area Category Method
- Tailored Method
The revised LPD values were developed accounting for increases in LED efficacy mandated by the California Appliance Efficiency Standards (Title 20) that were adopted in 2016 and the United Stated (U.S.) Department of Energy (DOE) LED efficacy regulations that are being developed concurrently to the 2019 Title 24, Part 6 Standards. This proposal builds upon efforts to update the LPD requirements in ASHRAE 189.1: Standard for the Design of High Performance Green Buildings.
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 firstname.lastname@example.org.
