Demand Response Cleanup

Residential and Nonresidential Demand Response (Including Changes to Space Conditioning, Lighting, Energy Management Control Systems, Power Distribution, and Solar Ready Sections)

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

The objective of this code change proposal is to clean up and clarify the existing demand response (DR)
requirements so that all sections of the standards use consistent terminology and approach. The goal is
to improve comprehension of and compliance with the existing requirements. The Statewide CASE
Team also strives to make it easier for occupants of compliant buildings to realize the economic benefits
of their buildings’ demand responsive controls by enrolling in DR programs.
The Statewide Utility Team recommends improvements to the language in the Standards, Reference
Appendices, Compliance Manuals, and compliance documents to:

  1. Improve the clarity of the code language without changing the stringency of the standards;
  2. Harmonize the demand responsive control requirements, including requirements related to the
    application of open or standards-based communications protocols;
  3. Clarify and improve the compliance and enforcement process; and
  4. Establish a foundation within the Title 24, Part 6 Standards, Appendices, Alternative Calculation
    Method Reference Manuals, and Compliance Manuals upon which additional measures that have
    load reshaping and ancillary service benefits can be added in future code cycles.

The modifications aim to align the terminology used in Title 24, Part 6 with terminology used by
industry, model codes, utility programs, and other regulating bodies such as the Federal Energy
Regulatory Commission and the California Independent System Operator (CAISO). Revisions also aim
to provide sufficient detail on how to comply with the standards while maintaining the appropriate level
of leeway to allow for continued market innovation and transformation.

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.
