What Is a CF1R? The First Step in Title 24 Compliance
What Is a CF1R?
The CF1R, or Certificate of Compliance, is the first document in California's Title 24 energy compliance chain. It is an energy model and report generated by an energy consultant that demonstrates how a proposed building design will meet or exceed the state's energy efficiency standards.
Who Prepares the CF1R?
The CF1R is typically prepared by a Title 24 energy consultant using approved compliance software such as CBECC-Res for residential projects or CBECC-Com for commercial buildings. The consultant models the building's envelope, HVAC systems, water heating, lighting, and solar to produce a report showing code compliance.
What Does the CF1R Include?
The CF1R includes the building's energy budget calculations, a list of required HERS or ECC verification measures (CF3R items), specifications for installed equipment, insulation R-values, window U-factors and SHGC ratings, and duct system requirements. It serves as the blueprint that contractors must follow and verifiers must check against.
Why the CF1R Matters for Your Project
Without an approved CF1R, your building permit will not be issued. The CF1R also determines which field verification tests your project will require. Getting the CF1R done early allows your team to plan for inspections, order the right equipment, and avoid costly change orders later in construction.
