What is Title 24 energy modeling?

California’s Building Energy Efficiency Standards are in Title 24, Part 6 of the California Code of Regulations. A project may follow applicable prescriptive requirements or, when eligible, use the performance approach to compare the calculated energy performance of the proposed design with a standard design using California Energy Commission-certified compliance software.

The applicable code cycle depends on the permit date and project scope. CEC-approved software is specific to occupancies and scopes such as multifamily, nonresidential, new construction, additions, and alterations. Final compliance documentation and responsible-professional requirements must follow the authority having jurisdiction and current CEC rules.

A compliance model tied to the actual permit path.

The service starts by identifying the code cycle, occupancy, project scope, compliance approach, responsible parties, and approved software requirements.

Multifamily modeling

Support applicable multifamily new construction, addition, or alteration workflows using the current approved compliance method.

Envelope & systems inputs

Prepare multifamily envelope, systems, loads, schedules, and other inputs for the applicable performance-compliance workflow.

Nonresidential modeling

Support commercial, high-rise, hospitality, healthcare, institutional, industrial-support, and other nonresidential scopes.

Performance-path analysis

Compare the proposed design against the standard design using the approved calculation method and current project information.

Design option testing

Evaluate agreed envelope, glazing, lighting, HVAC, controls, ventilation, and other changes before final documentation.

Documentation coordination

Track assumptions and approved inputs so energy-model information remains aligned with drawings, specifications, and responsible design teams.

From multifamily to high-rise and mission-critical.

The delivery framework adapts to each sector’s information, coordination, documentation, and approval requirements.

Multifamily residential

Apartments, condominiums, multifamily, and residential developments.

High-rise & commercial

Towers, offices, hospitality, retail, and mixed-use buildings.

Data centers

White space, grey space, power, cooling, redundancy, and handover.

Industrial

Manufacturing, utilities, equipment interfaces, access, and installation.

Healthcare & institutional

Hospitals, education, civic, and coordination-intensive facilities.

Infrastructure

Site, civil interfaces, utilities, logistics, and model-based sequencing.

Start with the code cycle—not a recycled model.

Permit timing, occupancy, addition or alteration scope, climate zone, software approval, and project responsibility determine the workflow.

  1. Confirm applicability

    Identify permit timing, code cycle, building type, project scope, climate zone, authority, responsible parties, and compliance approach.

  2. Assemble current inputs

    Collect geometry, envelope, glazing, lighting, schedules, loads, HVAC, controls, ventilation, service water heating, and project assumptions.

  3. Model and coordinate

    Use the applicable approved workflow, test agreed alternatives, resolve information gaps, and coordinate changes with the design team.

  4. Finalize documentation inputs

    Update the model for final design information and support the responsible project team’s compliance documentation and submittal process.

Clear answers on scope, responsibility, standards, and project setup.

Is Title 24 the same as California’s Energy Code?

Title 24 is the California Building Standards Code. The Building Energy Efficiency Standards are Part 6, commonly called the California Energy Code. Other parts of Title 24 cover different subjects.

Does every project use energy modeling?

Not necessarily. Applicable projects may use prescriptive or performance compliance approaches depending on occupancy, scope, and current rules. The project team should confirm the correct path for the permit.

Which software can be used for performance compliance?

The California Energy Commission publishes approved compliance software for each code cycle, occupancy, and scope. Only currently authorized tools and versions should be used for the applicable performance path.

Can BIM Bots sign Title 24 compliance documents?

Modeling and documentation support do not automatically include responsible-person certification or professional seals. Required signatures and compliance responsibility must be assigned to qualified project professionals under current California rules.

Does the 2025 Energy Code apply now?

The California Energy Commission states that permit applications made on or after January 1, 2026 must use approved 2025 compliance software. Project teams should verify current applicability and local permit requirements before starting.
