Florida building code energy efficiency changes affect HVAC system design requirements
Florida Building Code and Florida Energy Code were made 15% more stringent per Govern Crist. Go to Florida Department
of Community affairs to read about the changes.
2009 Supplements to 2007 Florida Building Code
Energy Code Update
Florida Building Code supplements took effect on March 1, 2009. These
changes have affected structural requirements of the envelope and how hvac equipment is selected.
HVAC efficiency for most situations will be 13 SEER. You may have been told that a higher SEER will be the only way to pass
the energy code – but improvements on the envelope and structure will not only pass the energy code but, help keep your
equipment size and cost down!
Equipment Sizing and Cooling Equipment Capacity procedures WILL CHANGE how HVAC equipment
is also selected. In addition, manufacturer’s performance data is required at permitting. Rule of thumb and law of average
sizing methods can lead to inadequate cooling or dehumidification (MOLD) issues, energy inefficiency, and shortened equipment
