Title 24 for Engineers
On a nonresidential job part of the Energy Code lives in your drawings, and the certificates follow the design discipline by discipline.

We work as documentation author, preparing the NRCC set from your drawings and schedules, or the CF1R on residential work. What stays with you is the responsible person's signature for your part of the design, and what Part 6 requires on the plans themselves. Commercial work is quoted per project; the signing rules are on who can prepare a Title 24 report.
What matters for your projects
One certificate per discipline
The NRCC-MCH-E covers mechanical, the NRCC-PLB-E water heating, the NRCC-LTI-E, NRCC-LTO-E and NRCC-LTS-E lighting, the NRCC-ELC-E electrical power distribution, the NRCC-SAB-E solar and battery, and the NRCC-PRC-E covered processes. Each person responsible for part of the design signs the certificates for that part, or the person with chief responsibility signs them all (Section 10-103(a)1). In the compliance manual's example a technician may complete the NRCC-MCH-E, but only the engineer of record on the design team can sign it as responsible person.
What the drawings have to carry
Where plans are required, the certificates are incorporated into them (Section 10-103(a)2A). For nonresidential buildings, high-rise residential buildings and hotels, the plans and specifications must also set out the acceptance requirements for each feature that has them, and carry a prominent note requiring record drawings to reach the owner within 90 days of the final occupancy permit (Section 10-103(a)2B).
Commissioning from schematic design
Nonresidential buildings with 10,000 square feet or more of conditioned space, healthcare facilities excepted, are commissioned under Section 120.8: owner's project requirements, a basis of design, a design review, commissioning measures written into the construction documents, a commissioning plan before the permit, then functional testing, training and a final report. Smaller buildings need the design review. On larger buildings the reviewer who signs it must have no other role on the project.
Electrical power distribution
Section 130.5 asks for metering on each service or feeder, circuits arranged so load types can be monitored separately, no more than 5 per cent combined voltage drop to the farthest load, and controlled receptacles in offices and similar spaces, documented on the NRCC-ELC-E. Lighting controls and mechanical systems also carry acceptance tests once they run; see Title 24 acceptance testing.
Cooling towers
Section 110.2(e) requires conductivity controls on cooling towers, and the maximum achievable cycles of concentration, calculated from the water quality the local supplier reports, documented on the mechanical compliance form and signed by the professional engineer of record.
Very small buildings
A building department may not require the Section 10-103(a) documents for a nonresidential building of up to 1,000 square feet of conditioned floor area with an occupant load of 49 or fewer, if a licensed engineer, or the licensed architect with chief responsibility for the design, submits a signed statement that it complies with Part 6.
Every project includes
- Permit-ready documentation for your scope
- Registration where your project requires it
- Unlimited revisions until you comply
- Direct contact with the analyst on your file
Frequently Asked Questions
Yes. The nonresidential compliance manual says a technician may complete it, but only the engineer of record on the design team can review and sign it as the responsible person.
Not if it has no more than 1,000 square feet of conditioned floor area and an occupant load of 49 or fewer, and a licensed engineer, or the architect with chief responsibility, signs a statement that it complies with Part 6.
The drawings and schedules for each discipline in scope: equipment schedules with efficiencies, the lighting fixture schedule with installed wattages, control sequences and plumbing equipment. We confirm which certificates apply before quoting.
