Florida Energy Code Guide — 2025

The Florida Energy Code for residential buildings (based on the IECC with Florida amendments) requires: **Building envelope:** Insulation in walls (R-13 minimum for wood frame), ceilings (R-30 minimum), and floors (R-13 for floors over unconditioned space). Air sealing is required throughout the building envelope. **Windows and doors:** Maximum U-factor of 0.40 and SHGC of 0.25 for most Florida climate zones. **Mechanical systems:** HVAC systems must meet minimum efficiency requirements (SEER 15 for air conditioners, HSPF 8.8 for heat pumps). Water heaters must meet minimum efficiency requirements. **Lighting:** At least 75% of permanently installed lighting must be high-efficacy (LED).

The Florida Energy Code for commercial buildings (based on ASHRAE 90.1 with Florida amendments) requires: **Building envelope:** Insulation in walls, roofs, and floors. Maximum U-factors and SHGC for windows and skylights. **Lighting:** Maximum lighting power density (LPD) for each space type. Occupancy sensors and daylight controls are required in many spaces. **Mechanical systems:** HVAC systems must meet minimum efficiency requirements. Energy recovery ventilation is required in some applications. Pineland Engineering prepares Florida Energy Code compliance documentation for commercial projects.
