CalBEM’s purpose is to empower California’s building energy modeling (BEM) community to identify, explore, and prioritize the challenges they share, and then support solutions to those challenges to help to promote low-carbon buildings.

In-person attendee details
CalBEM 2025 is gearing up to be an exciting event! As usual, we’ve lined up engaging in-person presentations: find our agenda sneak peek below, with additional speaker releases in October, along with our final agenda and schedule.
Keynote
Dr. Eric Fournier, UCLA Institute of the Environment & Sustainability
Eric Fournier is the research director at the California Center for Sustainable Communities (CCSC) – a research center housed within UCLA’s Institute of the Environment and Sustainability. Over the past decade, he has lead work on grant funded research projects for a variety of state agencies (CEC, CARB, CPUC, SGC, LADWP, etc.) focused on building decarbonization and distributed energy resources adoption.
In his keynote address, Eric will discuss several emerging challenges related to the implementation of California’s decarbonization initiatives whose solutions implicate the marriage of large scale building energy datasets with advanced building energy modeling techniques.

What is CalBEM?
CalBEM (California Building Energy Modeling) is a stakeholder collective and an annual statewide event hosted by Southern California Edison on behalf of the California Investor-Owned Utilities. CalBEM collaborates to identify and pursue systemic solutions in building energy modeling that advance California’s climate action goals. CalBEM participants come together each year at the annual Symposium to join interactive collaboration sessions and learn from energy modeling leaders across CA. Workshop sessions will cover each of CalBEM’s three Working Groups: Streamline & Simplify Processes, Educate Users, and Improve Capabilities & Accuracy.
Read more about CalBEM’s core goals and what the Working Groups are up to these days.
