CA Title 24 Forms

California building code

In California, energy efficiency standards for residential and non-residential buildings were established by legislation in 1978 in order to reduce California’s energy consumption. Building energy efficiency is addressed in Title 24, part 6 of the coding manual.
Today we are going to speak particularly about CA Title 24 forms after a small introduction of Title 24 itself as long as the CA Title 24 forms are numerous and complicated and they include important information pertaining to the construction and energy efficiency of your home such as surface areas, insulation levels, window performance, heating & cooling systems, water heating, and much more.
What is Title 24 energy report? - A Title 24 energy report is a set of forms that verify your proposed building design complies with the California Title 24 energy standards. Title 24 compliance documentation needs to be submitted to the building department prior to the issuance of building permits when building either a new home or adding an addition to an existing home and with today’s current energy requirements, it is necessary to model the existing space as well as the new space to achieve compliance.

What Information do the Title 24 Form Contain?

The forms contain important information pertaining to the construction and energy efficiency of your home such as surface areas, insulation levels, window performance, heating & cooling systems, water heating, and much more. The “performance” forms include a complex energy calculation. As it is already pointed the forms are numerous and complicated and you would be limited to the “prescriptive” method of compliance. A better, more flexible compliance approach is the “performance” method where details of the proposed construction are input into specialized software. The software calculates the minimum level of energy efficiency necessary for compliance then automatically creates the required compliance forms.

Utilities, Electric Generation, and Natural Gas Reporting

The California Energy Commission is required to collect and analyze data related to electricity generation, sales, and deliveries from power plant owners, investor- and publicly-owned utilities, grid operators, and pipeline companies in California.

  • Electricity Forms

The California Energy Commission conducts assessments and forecasts of energy supply, production, transportation, delivery, distribution, demands, and processes, as mandated. To carry out these responsibilities, the Energy Commission manages a data collection system to gather the needed information to develop policy reports and analyses. Each utility distribution company and load-serving entity with retail electric customers in California must submit the relevant forms annually.

  • Natural Gas Forms

The California Energy Commission conducts assessments and forecasts of energy supply, demand, production, transportation, delivery, distribution, and processes, as mandated. The Energy Commission manages a data collection system to obtain the required information to develop policy reports and analyses. Each natural gas utility that delivers natural gas to customers in California, each gas producer that consumes natural gas in California, and each natural gas marketer, retailer, and energy service provider that sells natural gas in California must submit the required forms annually.

Emission Performance Standards

The standard limits long-term investments in baseload generation by the state’s utilities for power plants based on greenhouse gas emissions.

The emissions performance standard (EPS), established by Senate Bill 1368 (Perata, Chapter 598, Statutes of 2006), limits long-term investments in baseload generation by the state’s utilities for power plants based on greenhouse gas emissions.

The California Energy Commission established an EPS for the baseload generation of local publicly owned electric utilities. The standard is a rate of emissions of greenhouse gases that is no higher than the rate of emissions of greenhouse gases for combined-cycle natural gas baseload generation. All financial investments must meet the EPS.

The following types of EPS compliant investments include:

  • Construction or purchase (turnkey agreements) of new power plants designed and intended for baseload generation.

  • Purchase of existing power plants designed and intended for baseload generation, or ownership shares thereof, other than combined-cycle natural gas power plants in operation or permitted before June 30, 2007. 

  • Capital investments in existing utility-owned power plants designed and intended for baseload generation, other than those for routine maintenance, that: 

    • For combined-cycle, natural gas power plants permitted before June 20, 2007, increase the generation capacity by 50 megawatts (MW) or more.

    • For other power plants, intended to extend the life of one or more units by five years or more.

    • Intended to increase the rated capacity of the power plant.

    • Intended to convert a non-baseload power plant into a baseload power plant.

2019 Building Energy Efficiency Standards

The 2019 Building Energy Efficiency Standards improve upon the 2016 Energy Standards for new construction of, and additions and alterations to, residential and nonresidential buildings. Buildings permitted on or after January 1, 2020, must comply with the 2019 Standards. The California Energy Commission updates the standards every three years.

Docket Unit

Most documents filed after 2009 are available electronically through the docket. Upon request, the Docket Unit will provide copies of docketed materials if they are not available from the Energy Commission Library or website.



California Code of Regulations Title 20, section 1002 directs service of process on the Energy Commission to be made by personal service on the chair, executive director, or chief counsel.

Due to the impacts on operations from the coronavirus, the commission will accept service via a notice of acknowledgment and receipt (CCP section 415.30) for the duration of the state of emergency, if the notice and the papers being served are emailed to the following agency email address: [email protected]

Note: if you are attempting to personally serve an employee of the Energy Commission, electronic service on the Energy Commission will not be accepted.



In certain instances, copies of docketed material also are available at selected libraries throughout California and in communities affected by a proposed or permitted facility. A party submitting a document to the Energy Commission can request that it be kept confidential by filing an application for confidential status. The application must be approved by Energy Commission’s executive director

Title 24 Compliance Documentation

One of the most frequently asked questions is about the deadline for Title 24 compliance documentation. So we are letting you know that Title 24 compliance documentation needs to be submitted to the building department prior to the issuance of building permits when building either a new home or adding an addition to an existing home. Also The best time to submit your plans is when you have made all of the decisions about your building project.

Be sure of the window and door sizes and their locations. However, if you haven’t decided on the manufacturer for the windows and doors we can still do our calculations, but we get the best results if you have already made that decision. The reason is that we can use specific data pertaining to the fenestration products you select.

It is best to decide how you intend to heat your home, whether it is a forced-air or radiant floor, as well as whether you will have air conditioning or not.

Typically, Title 24 calculations are one of the last things you should do before submitting your plans to the building department for approval.
