Pre-Rulemaking on
2019 Building Energy Efficiency Standards

Commissioner: Andrew McAllister

About the Pre-Rulemaking

The California Energy Commission will be opening a public process and rulemaking proceeding to adopt changes to the Building Energy Efficiency Standards contained in the California Code of Regulations (CCR), Title 24, Part 6 (also known as the California Energy Code), and associated administrative regulations in Part 1 (collectively referred to here as the Standards). The updated standards will be proposed for adoption in 2018 with an effective date of January 1, 2020. Previously open Docket 2016-BSTD-06 for the 2019 Time Dependent Valuation (TDV) of Energy has been closed. The Energy Commission has opened Docket 17-BSTD-01 for pre-rulemaking comments on proposed 2019 Standards measures.

The California Energy Commission staff will conduct workshops to present potential revisions to the Standards and obtain public suggestions and comment. The scope, time, and date of these workshops will be publicly noticed.

Interested parties should be aware the California investor-owned utilities (IOUs) and some publicly owned utilities (PUCs) conduct the statewide Codes and Standards programs through rate payer funds. To support the 2019 revisions to the Standards, the IOUs and POUs are conducting a number of Codes and Standards Enhancement (CASE) Initiatives. These Initiatives address areas of potential change to the Standards that show promise, based on the results of utility research, and the success of incentive programs and document the potential energy savings, cost implications, and specific approaches. Although outside the scope of the Energy Commission's rulemaking proceeding for the 2019 Standards, these Initiatives are important. The California Energy Commission expects the IOUs and POUs to engage building industry stakeholders throughout the development of the CASE Initiatives so that these initiatives will be adequately vetted with affected stakeholders prior to proposing potential revisions to the Standards.
