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.

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.
