Florida Energy Code Compliance Guide

The Florida Energy Code for residential buildings (one- and two-family dwellings and low-rise multi-family) is based on the International Energy Conservation Code (IECC) with Florida-specific amendments. Key requirements include: building envelope thermal performance (insulation R-values, window U-factors and SHGC), HVAC efficiency (minimum SEER ratings), water heating efficiency, and lighting efficiency. Compliance can be demonstrated through the prescriptive path (meeting specific minimum requirements) or the performance path (energy modeling).

The Florida Energy Code for commercial buildings is based on ASHRAE 90.1 with Florida-specific amendments. Key requirements include: building envelope thermal performance, HVAC system efficiency, lighting power density, and service water heating efficiency. Compliance is typically demonstrated through energy modeling using software such as EnergyPlus or eQUEST.

Florida requires that HVAC systems for new residential construction be designed using Manual J (load calculation) and Manual D (duct design) procedures. The Manual J load calculation determines the heating and cooling loads for the building, and the Manual D duct design ensures that the HVAC system can deliver the required airflow to each room. Pineland Engineering provides Manual J and Manual D calculations for residential projects.
