Title 24 Calculations and Commissioning Services for Nonresidential Buildings in California
If you are designing or constructing a commercial building in California, Title 24 compliance is not optional. The 2025 Energy Code expands design review and commissioning requirements for nonresidential projects, making professional Title 24 Calcs essential from schematic design through occupancy.
Our Title 24 consultants help architects, developers, engineers, and property owners navigate California’s energy regulations while avoiding plan check delays, redesign costs, and construction setbacks. All services align with the 2025 Nonresidential Design Review and Commissioning requirements issued by the California Energy Commission.
What the 2025 Title 24 Standards Require
The 2025 Energy Code defines commissioning as a quality assurance process that verifies systems are planned, designed, installed, and operated according to the owner’s energy goals. Design review focuses on improving regulatory compliance and ensuring systems can be built and maintained.
Projects That Must Complete Commissioning
Full commissioning is required for:
- Newly constructed nonresidential buildings with 10,000 square feet or more of conditioned space
- Mixed use buildings where nonresidential areas exceed 10,000 square feet
Smaller projects still require design review and acceptance testing. Additions, alterations, hotels, multifamily housing, and licensed healthcare facilities are excluded from Part 6 commissioning rules.

- Commissioning support documentation
- OPR and BOD preparation
- Commissioning plan assistance
- Construction phase verification
- Certificate of occupancy readiness
Why Early Title 24 Modeling Is Critical
The Energy Code requires commissioning tasks to begin during schematic design, including kickoff meetings and preparation of OPR and BOD documents. These steps rely directly on early Title 24 Calcs for HVAC systems, lighting layouts, and envelope assemblies.
Starting compliance late increases the risk of:
- Failed plan check reviews
- HVAC redesign
- Lighting system reconfiguration
- Permit delays
- Construction change orders
The Commissioning Workflow We Support
Design Phase
- Design review kickoff meeting
- OPR development
- Basis of Design preparation
- Design review documentation
- Permit ready Title 24 Forms
Permitting Phase
- Integration of commissioning measures
- Draft commissioning plans for large projects
- Submission of acceptance testing forms
Construction Phase
- Functional performance testing coordination
- Operations and maintenance manuals
- Facility staff training records
- Final commissioning reports
These steps are required before issuance of the certificate of occupancy.
Who Performs the Design Review
Reviewer qualifications depend on building size and mechanical system complexity. Large or complex buildings require independent third party reviewers, while smaller projects may allow in house engineers or architects not associated with the design team.
Required Title 24 Forms We Prepare
For qualifying nonresidential buildings:
- NRCC CXR E Certificate of Compliance
- NRCA Acceptance Certificates
- NRCV Verification Certificates
- OPR and BOD
- Commissioning Plan
- Operations Manuals
- Commissioning Report
