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 promote low-carbon buildings.

Andrew McAllister was first appointed to the California Energy Commission in 2012, and in 2022 was reappointed by Governor Newsom to a third term. Commissioner McAllister’s priorities include: decarbonization of buildings and industry; energy efficiency of buildings and appliances; load flexibility as a tool for grid optimization; improving access to data and analytical tools that can drive innovation at the grid edge; alignment of energy and housing policy & programs; and amplifying California’s innovation-centered approach through collaboration with diverse partners beyond its borders. 

Commissioner McAllister has worked in the utility, energy efficiency and renewable energy spaces for more than three decades. Prior to CEC he served as managing director of a California-based clean energy non-profit; energy efficiency and renewable energy specialist at an international development organization; utility energy efficiency program consultant; and researcher at a DOE national laboratory. He has worked in numerous countries to deploy clean, cost-effective energy solutions partnering with counterparts ranging from tiny remote communities to the largest of utilities. 

Commissioner  McAllister is past board chair of the National Association of State Energy Officials and the Western Interstate Energy Board. He also serves on the boards of the Smart Electric Power Alliance, the Dartmouth Irving Institute for Energy and Society, and Camp Kesem at UC Davis. He holds M.S. and Ph.D. degrees from the Energy and Resources Group at the University of California, Berkeley, and a B.A. from Dartmouth College. He served as a U.S. Peace Corps volunteer.

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.
