Instructions:

  1. Checklist Tab:

    • Check the boxes indicating which documents will be included with the submission of this form.

  2. Project Info Tab:

    • Enter the required project information: Project Name, Project Address, Project County, Owner, whether it is a Worst Case analysis, and the project's Conditioned Floor Area [square feet]. 

    • Enter any additional available information, including Builder, Permitting Office, Permit Number, and Jurisdiction Number.

    • All “INSTALLED” values must be equal to or more efficient than the required levels. 

    • Note: the top left corner of the previous page, FORM R402-2020, shows the Climate Zone.

    • “AVG” indicates the allowed area-weighted average.

    • “LOWEST” indicates the lowest allowable R-value to be installed.

    • Only fill in values for building components that are being replaced. 

    • Enter "N/A" for any components not being replaced as part of this project's scope. 

    • Check the box indicating whether the project Passes or Fails the R-Valuation Method.

  4. Equip Requirements Tab:

Climate zone

Form R402-2020 is a fillable code document, not a calculation: of its eighty-three entry cells, the county is the only one any formula reads. This page keeps that lookup. The eighty-two remaining cells are typed in, read by nothing, and reappear unchanged in the two test-report headers, so they are left to the printable form itself.

Climate zones are the 2020 Florida Building Code, Energy Conservation (7th Edition) assignment: Broward, Collier, Hendry, Lee, Miami-Dade, Monroe and Palm Beach are Zone 1A and the other sixty counties are Zone 2A. Florida has since moved to the 8th Edition (2023); the zone assignment is unchanged there, but the equipment efficiencies printed on the source form are not.

Marion County is spelled "Marlon" in the published dropdown. It is kept as published so the entry still matches; the climate zone it returns, 2A, is correct.

Welcome to the 2020 Florida Energy Conservation Code's Fillable Form 402. Adicot's fillable form allows users to easily and quickly calculate compliance with Florida's Energy Code requirements. This form is based on the 7th Edition of the Florida Energy Conservation Code and includes the 2022 Supplement to the 7th Edition (2020) Florida Building Code. It is a fillable form, so users can quickly update and save their calculations for future reference. This form is invaluable for engineers, contractors, architects, and builders.
