Group 1: Creating a Streamlined BEM Process
During CalBEM 2020, Working Group 1 flagged complexity in energy codes as a significant barrier to achieving well-understood performance modeling requirements, intuitive compliance reviews, and useful verification processes. The group’s top priority for 2021 is to identify opportunities to reduce the complexity in performance-based codes. In January this group held a webinar reviewing the many simplified performance compliance pathways aiming to reduce the complexity of analysis, reporting, and verification in the compliance process. The team discussed several simplified paths including a simplified whole building performance approach for small, simple buildings, HVAC System Performance compliance path, EUI targets and prescriptive packages.
This summer, Co-Chairs Neal Kruis and Supriya Goel want to dive deeper into each pathway, as prioritized by the group.
Group 2: Developing BEM Education and Resources
The Recommendations for Building Energy Modeling Education in California project is officially underway, spearheaded by Emily Courtney and her team at Strategic Energy Innovations (SEI). The project seeks to identify high priority gaps in educational resources needed to increase the effective use of building energy modeling to design new buildings and improve existing building performance. SEI will make a progress report to Working Group 2 members in July.
Group 2 is continuing to explore the landscape of BEM reporting in California. In May the group will meet to hear speakers discuss the current development status of compliance and noncompliance output reporting, and opportunities for improvement in both:
- Discussion Topic 1: Status of CBECC Output and Reporting and Development – Opportunities for Change
- Review of compliance report content development. Sally Blair
- CBECC Res output data and possibilities. Scott Criswell / David Reddy
- Discussion Topic 2: Reporting End Uses – Beyond Code Compliance
- Design assistance. Providing useful information to designers and decision makers. Nick Brown, Dave Intner, Tim Kohut
- Quality control. Providing information for modelers to help evaluate the quality of their models. Marina Chavez-Blanco / Gina Rodda, Brian Selby, Greg Collins
Group 3: Advancing BEM Capabilities and Metrics
At Working Group 3’s latest meeting, Haile Bucaneg was welcomed as the group’s new Co-Chair alongside Neil Bulger. Halie stressed that strategies for shifting load are more important than ever and provided an overview of the CEC’s new load management standard and the LMS MIDAS* Rate Database structure. This group has also been hard at work collecting feedback on a project that will allow the public to submit efficiency enhancement ideas to California code compliance software teams. *Load Management Standards (LMS) Market Informed Demand Automation Server (MIDAS)
Also on the topic of Advancing Capabilities, CalBEM is now the proud host of the Ecosizer tool, a free educational tool for sizing central water heating systems with heat pump water heaters in multifamily buildings.

What are Working Groups?
A Working Group is a team of CalBEM participants dedicated to furthering one of CalBEM’s core goals. During CalBEM events they discuss potential solutions (imagined or inspired by solutions seen in other jurisdictions) to issues identified in the sub-topics explained below. In-between CalBEM events, they work to finalize and execute on projects inspired by these events.
Each Working Group has two designated co-chairs selected based on their experience and involvement related to the Working Group sub-topics. Prior to each event, these individuals work with the host (SCE) and facilitators (2050 Partners and Red Car Analytics) to structure the Working Group breakout sessions (e.g., sub-agenda, presentations, handouts, activities, etc.).
The Working Group sub-topics were chosen with the following criteria in mind:
- Responsive to feedback from BEM stakeholders,
- Addresses issues that are not being addressed in another forum, or adds value to an existing process but is not duplicative, and
- Focuses on issues for which the Working Groups can reasonably develop useful draft Action Plans within a two-day event.
The Working Groups are organized around three core CalBEM goals:

What are Action Plans?
During CalBEM events, the Working Groups prioritize sub-topics and then refine and develop problem statements, goals, and actions for the prioritized sub-topics. These materials form the backbone of robust Action Plans.
The Action Plan structure is organized around the problem statements. Each problem statement will have one or more actions to be taken that create movement towards resolution of the stated problem. Each action includes priority, status, lead stakeholders, other stakeholders, key barriers, schedules and notes.
Meetings and Webinars
After the completion of the annual CalBEM event, the Working Groups develop projects based on the issues identified in the Action Plans and continue to support a developed and functional building energy modeling ecosystem in California.
