Webinar Recording Now Available: Why Climate Zone and Building Type Matter Under California's 2025 Energy Code

Missed the live webinar? You can now watch the recording on demand in the GreenPoint Rated Virtual Classroom.

California's 2025 Energy Code introduced a new Long-Term System Cost compliance framework, raising important questions about how residential projects perform under the new methodology. In this webinar, Habinex and Redwood Energy share findings from a statewide modeling study exploring how climate zone, building type, electrification, and system selection influence residential energy performance.

You'll gain practical insights into:

• How the new Long-Term System Cost framework evaluates residential building performance.
• Why similar building designs can produce different compliance outcomes across California.
• The role of domestic hot water systems, photovoltaics, batteries, and electrification in modeled performance.
• Why mixed-fuel projects may face greater compliance challenges under the new framework.
• What these findings mean for GreenPoint Rated and future program enhancements.

If you haven't already, be sure to read our companion report, Why Climate Zone and Building Type Matter Under California's 2025 Energy Code, which summarizes the study's methodology and key findings in greater detail.

Whether you're a GreenPoint Rated Rater, architect, designer, builder, energy consultant, or code official, this webinar will help you better understand residential energy compliance under California's 2025 Energy Code.
