I-REN C&S Training: 2025 Code Series: Electrification Strategies for Contractors and Architects
- Webinar
The 2025 Energy Code encourages electrification, increasing electric-ready requirements and expanding the baseline for heat pump water heating to more building types. These changes will require a major paradigm shift in the way builders, architects and related professionals approach the market, while also presenting an opportunity to frame yourself or your business as an electrification expert. In this online session, Electrify My Home will discuss this transition and the related business opportunity for specifying and installing well-designed all-electric buildings.

- Webinar
Join I-REN and the California Energy Commission to learn about the 2025 Restructured Code! The 2025 Restructured Code was created in response to industry feedback that structuring the Energy Code similarly to other Parts of Title 24 would aid in navigation and use. This “Restructured Code” reorganizes the adopted code language, but has not been formally adopted; it is for informational purposes only, to gather feedback from the industry and inform the development of the 2028 Energy Code. This presentation provides some background into its development, and insight into the new reorganization scheme. Instructor: Allen Wong from the California Energy Commission
