Frequently Asked Questions

What is Title 24? 

The California Building Standards Commission created the California Building Standards Code in 1978. Title 24, Parts 6 and 11 refers to the section of code addressing building energy efficiency.

Do I need a Title 24 report?

Before being issued a building permit in California your local building department will require you provide Title 24 energy calculations, also known as a Title 24 report.

What's included in a Title 24 report?

A Title 24 report contains information about your project relevant to building energy efficiency such as surface construction, glazing, insulation, water heating, HVAC, climate information and more.

What do I receive when I order a Title 24 report?

A residential certificate of compliance (CF1R-PRF-01-E), HVAC loads summary, and a residential mandatory measures summary are emailed to you upon completion of your project.

How much does a Title 24 report cost?

Pricing is based on the square footage. For residential projects exceeding 5000 ft² please email us with your drawings attached to receive a quote.

  • Up to 500 ft²     -   $300.00

  • 501 - 1000 ft²    -   $350.00

  • 1001 - 2000 ft²  -   $400.00

  • 2001 - 3000 ft²  -   $450.00

  • 3001 - 4000 ft²  -   $500.00

  • 4001 - 5000 ft²  -   $550.00

How long does it take to get my report?

Turnaround is typically 1-3 business days.

What information do I need to provide?

  • Floor plan

  • Exterior elevation views

  • Window/door schedules

  • HVAC type

  • Water heater type

  • Building orientation

  • Project address

  • Designer contact information

How do I order a Title 24 report?

Submit an order using the form on our order page or simply email us your drawings and a brief description of your project. An energy consultant will quickly respond with a quote and turnaround.

What are the 2019 building efficiency standards?

The 2019 California Energy Code became effective on January 1st, 2020.

Key areas of focus include residential photovoltaic (PV) systems, thermal envelope standards, and non-residential lighting requirements. Homes built since the implementation of this code average 53% more energy efficient when compared to the 2016 standards.

What are mandatory requirements?

One of the three main components that make up structure of California's energy code, these measures cover subjects from infiltration control and lighting to insulation levels and equipment efficiency. While occasionally superseded by stricter requirements, these are the minimum levels that must be met.

What is the prescriptive method?

This approach utilizes a set of predefined performance levels. While using prescriptive standards is the simplest route it is also the least flexible. With this method each building component must meet or exceed the minimum efficiency levels specified in California's energy code.

What is the performance method?

The performance method offers considerably more design flexibility. Also known as the computer compliance method, energy compliance is met here using an approved software program to model proposed construction and compare it to a calculated energy budget. This method is far more popular because of its flexibility and ability to provide the most cost-effective compliance solution.
