February 25th Technical Dinner: 2026 Code Breaker: Nonresidential, Hotel/motel and Multifamily Envelope and Embodied Carbon

February 25 @ 5:30 pm - 8:00 pm

Presenter:

Gina Griffiths Rodda is currently the Owner of Gabel Energy out of Castro Valley, California, and has been in the energy modeling field since 1991. She is an energy analyst performing a wide range of responsibilities in both residential and nonresidential construction pertaining to compliance standards and energy modeling within the United States, while specializing in California Building Code. California local ordinances (or Reach codes) supporting electrification and electric preferred for multifamily, hotel/motel and nonresidential buildings dictates much of the work Gabel Energy provides in Northern California. Gina has worked with Energy Code Ace as a subject matter expert developing and supporting trainings, resources and tools on the Residential and Nonresidential Title 24 Building Energy Efficiency Standards for building department staff, energy consultants, engineers, contractors and architects.

Synopsis of Presentation:

The 2025 Energy Code (Title 24, Part 6) requirements for Nonresidential, Hotel/Motel and Multifamily envelope features including roof, wall, floor and fenestration for all scopes of work (new construction, additions and alterations), have been revised. We will review the Energy Code envelope updates along with the embodied carbon requirements of Title 24 Part 11 (CALGreen).

Learning Objectives:

1) Determine which section(s) of the 2025 Energy Code apply to Nonresidential, Hotel/Motel and Multifamily buildings.

2) Discuss the envelope (roof, walls, floors, fenestration, solid doors) requirements under the 2025 Energy Code for both Nonresidential, Hotel/Motel and Multifamily buildings.

3) Recognize how the Energy Code requirements for newly built spaces differs from the requirements for altered spaces.

4) Describe the importance of managing embodied carbon in achieving California’s climate goals.

5) Explain how to measure and reduce embodied carbon and support design decisions with the most significant impact as required by Title 24 Part 11 (CALGreen).
