Title 24 Part 6

Title 24 calculations are required by the California Energy Code (Part 6) to demonstrate your building project meets minimum energy efficiency standards. Whether your project is residential or non-residential, a Title 24 Part 6 calculation is usually required to obtain a building permit.

Residential energy calculations cover single-family homes, ADUs, remodels, and multifamily dwellings up to three stories. Non-residential energy calculations apply to commercial buildings, offices, retail, industrial spaces, and high-rise residential buildings. Each type follows specific Title 24 Part 6 requirements.

You can email us your architectural plans (preferably in PDF format). For a smooth process, include site plans, elevations, floor layouts, and any mechanical or lighting info. We’ll take it from there and begin your Part 6 energy calcs right away.

Most Title 24 calculations are completed within 2–3 business days. Rush service is available for tight deadlines. We understand how important fast turnaround is for permitting.

You’ll receive a signed and registered Title 24 Part 6 compliance report (CF-1R), ready for permit submission. We also provide a summary of compliance measures and help respond to any plan checker questions.

Yes. We use CEC-approved energy modeling software and follow California Energy Commission standards for all residential and non-residential energy calculations. Our assessors are trained and qualified to ensure accuracy and compliance.

Absolutely. We’ll work with you and your design team to find cost-effective solutions that bring your project into compliance, without over-engineering. Our goal is to help you pass — without adding unnecessary construction costs.

Prescriptive compliance follows a set checklist of components (like insulation values or window types). Performance-based Title 24 calculations use software modeling to show the project’s overall energy efficiency. Performance offers more flexibility and is the most common path we use.

Yes. Any project that involves adding conditioned floor area, changing windows, or modifying mechanical systems typically requires residential energy calculations to demonstrate compliance with Title 24 Part 6.

We combine speed, accuracy, and deep code knowledge. With years of experience delivering residential and non-residential energy calculations, fast turnaround times, and real-world construction insight, we make sure your project is energy ready — the first time.
