Nonresidential Indoor Lighting Power Densities (LPDs)

Measure Description

This indoor light power densities (LPDs) measure revises the lighting power allowances assigned in Tables 140.6-B, 140.6-C, 140.6-D, and 140.6-G to adjust the values to be comparable in energy efficiency to the levels presented in ASHRAE 90.1. This proposal results in modifications to Sections 140.6 of the Title 24, Part 6 California Energy Code. The proposal does not result in changes to the Reference Appendices. CEC adopted the 2016 Standards and Reference Appendices on June 10, 2015. The compliance manuals and compliance forms will be updated to reflect the changes to the standards. This change does not require changes to the Alternative Calculation Manual (ACM) Reference Manuals or the compliance software.

Summary of Revisions that Occurred during CEC Pre-rulemaking and Rulemaking

The Statewide CASE Team solicited feedback from a variety of stakeholders when developing the version of the CASE Report that CEC used as a “document relied upon” in their rulemaking package (see Appendix A). In addition to personal outreach to key stakeholders, the Statewide CASE Team conducted a public stakeholder meeting to discuss the proposal on May 15, 2014. Feedback that stakeholders provided during the utility-sponsored stakeholder meeting is summarized in Section 2.4 of the report presented in Appendix A. See Section 3 for additional information about changes that occurred during CEC’s prerulemaking and rulemaking processes.
