Also called

FBC-EC, FBC, Energy Conservation, Florida Energy Efficiency Code for Building Construction

The Commission’s energy changes list and the DBPR brochure describe the Energy Conservation volume as the 7th Edition (2020) base code with 2021 IECC changes. The Commission’s certification letter compares the commercial provisions to ASHRAE 90.1-2019 and notes selected 2021 IECC changes.

Exceptions

• Buildings, structures and facilities exempted from the Florida Building Code by s. 553.73(10), Fla. Stat. (for example drone ports, chickees, equipment in a spaceport territory)
• Local governments may adopt administrative amendments and more-stringent local technical amendments under s. 553.73(4); local technical amendments take effect 30 days after the Commission receives them

  Planned for Dec 31, 2026ProposedRule 61G20-1.001, F.A.C. (notice of proposed rule, Florida Administrative Register Vol. 52/185, Sep 23, 2026)

  The Commission reviewed the 2024 IECC. No direct statement of the 9th Edition commercial energy base (IECC or ASHRAE 90.1) was found. Under s. 553.73(7)(e) as amended by ch. 2023-211, the Commission can delay the energy provisions of an updated code. Based on a summary of the enrolled text, the delay is up to 3 months when compliance software is not approved at least 3 months ahead. The effective date is the Commission workplan target. The final rule hearing was still TBD on Oct 17, 2026, and s. 553.73(7)(e) requires at least 6 months after publication of the updated code.

How Florida adopts the IECC commercial

• Agency rule
• The legislature sets the update schedule
• The legislature reviews the rules and can block them
• A recent law changed the process

The Florida Building Commission adopts each triennial edition, including the Energy Conservation volume, by rule under Chapter 120 (s. 553.73(1)(a), (7)(a)), reviewing updates based on the IECC while maintaining the efficiencies of the Florida Energy Efficiency Code, and the rule takes effect no sooner than 6 months after publication (s. 553.73(7)(e)). Ch. 2023-211 lets the Commission delay the energy provisions’ effective date when compliance software is not approved in time. General Chapter 120 oversight applies (JAPC review is built into the workplan; ratification under s. 120.541(3) only if estimated costs exceed the thresholds), and local governments may add more-stringent technical amendments effective 30 days after the Commission receives them (s. 553.73(4)).

Cycle. Triennial by statute (s. 553.73(7)(a)); 8th Edition effective Dec 31, 2023, 9th Edition targeted for Dec 31, 2026; interim amendments and errata between cycles.
