Group 2: Developing BEM Education and Resources
Co-Chairs: Erik Kolderup and Nick Brown
Working Group 2 held a webinar in October to review an outline of a project proposal focusing on increasing student awareness of BEM and BEM-related careers. The Co-Chairs shared the draft project scope and attendees provided input and recommendations. Part of the project is leveraging modelers to be lecturers at a local university, meeting attendees raised their hand to contribute, and there’s a healthy group to draw upon once the project is scoped and finalized. The Co-Chairs have identified two groups interested in developing a project proposal for Steering Committee review, and will coordinate with those individuals to submit a project proposal
WG2 plans the following agenda at the November CalBEM 2024 Symposium:
If you have missed these recent meetings, notes and slides can be found in the CalBEM Collaborative Efforts SharePoint here.*
The “Open Source Data Visualizations for BEM Quality Assurance” project led by Greg Collins (Zero Envy), was approved by the Steering Committee in June 2024 has a lead on a project funder and awaiting final confirmation.

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:
Creating a Streamlined Process for Building Simulation
This group focuses on opportunities to streamline compliance processes through software enhancements, new innovative methods in validation or types of performance compliance, compliance metrics, and software application interoperability.
Co-Chairs: Supriya Goel (Pacific Northwest National Laboratory), Neal Kruis (Big Ladder Software), and Dimitri Contoyannis (Model Efficiency)
Key Sub-topics:
-
- Future of Public and Private Code Compliance Software – What strategies could CA explore to expand compliance software to be more accessible, easier to use, and easier to develop by the market? Shaping a Ruleset Validation Standard is one example related to the idea of moving regulatory bodies out of the role of creating software and yet maintaining a level of control and calculation quality.
- National Alignment – What efforts are being undertaken by national code agencies or green building rating groups to streamline energy modeling compliance and new performance pathways for users? What alternate strategies should CA agencies for codes, programs, or local incentives consider which may be currently implemented or being piloted elsewhere?
- Software Interoperability and New Developments – With energy modeling tools improving and expanding to now include whole eco-systems of software, what needs exist for interoperability? Where the need exists today for multiple models, how could interoperability be enhanced to streamline or change the current dilemma of non-interoperability?
Educating BEM Users and Developing Resources
Group 2 focuses on enhancing resources for the energy modeling community of technical users and agencies, including enhancing shared resources, developing robust methods and documentation for compliance with codes, incentives, and state programs, and prioritizing the most educational items.
Co-chairs: Erik Kolderup (Kolderup Consulting) and Nick Brown (Build Smart Group)
Key Sub-topics:
-
- Creating a Robust Reporting Process – In both code compliance and in green building standards, review of results and documentation of calculations is necessary. What best practices exist for enhancing compliance of models that are created, such as peer review and automated checks of modeling files? For documentation itself, where could enhancements or simplifications be made in state documents for codes and program administrators’ documents for incentives and where are examples for such available in the industry, be it states or through private rating systems such as LEED?
- Educating a Larger Workforce & Advancing Skills – As energy modeling and software inform more elements of the built environment, what ways can the BEM community further attract talent and teach the necessary skills to support this expanding scope? What gaps exist today? What are the priorities for enhancing workforce education? What educational resources could be developed to enhance the general knowledge for properly modeling in specific software or in general?
Advancing BEM Simulation Usability, Accuracy, & Capabilities
CalBEM Group 3 focuses on increasing the usability, accuracy, and capabilities of California building energy modeling documentation, software, and technologies. Topic areas include energy modeling software for Title 24, Part 6 and for statewide programs. Efforts focus on short-term enhancements, encompassing the current or near-term energy code software, or long-term over the upcoming one to two code cycles.
Co-chairs: Neil Bulger (A2 Efficiency), Haile Bucaneg (California Energy Commission), and Michael Sawford (A2 Efficiency)
Key Sub-topics:
- Advancing Software Usability and Accuracy – Through assessment and testing of Title 24 code, modeling methods, and new software updates impacting the current and next one to two code cycles.
- Advancing Methods and Capabilities of Compliance and Program Software in the Market – through enhancing interactions between programs and compliance, improving efficiency measures that are allowed in compliance software to streamline the use in incentive programs (reduce workarounds for clean compliance documentation).
- Advancing the Usability of Documentation and Rulesets – Through assessment and review of the Title 24 reference manuals align documentation with original intent improving usefulness to practitioners and software developers. What adjustments should be made to improve the usability of existing documentation and technical educational materials?

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. Visit the CalBEM events calendar here.
