This study was commissioned by the Florida Department of Community Affair’s Codes & Standards Section to determine the impacts of Florida’s Energy Code over time and recommend possible changes that would increase residential efficiency. It examines each of the 15 residential energy code cycles that have occurred during the 30-year period from 1979 to 2009, and determines the relative change in energy code efficiency and its impact on energy use and energy cost throughout the period. The study has been revised to include Florida’s 2009 supplement to its 2007 energy code to determine how its requirements compare with the requirements of Section 405 of the 2009 International Energy Conservation Code. Florida’s energy code compliance software, EnergyGauge® USA, is used to conduct annual, hourly simulations and analysis of 180 different home configurations. These results are combined with Florida’s historical energy cost data and new home construction data to determine...

In compliance with Title III of the Energy Conservation and Production Act of 1976, as amended, the Florida Building Commission, which has statutory authority to administer the Florida Building Code (s. 553.72(3), Florida Statutes), hereby certifies that Chapter 5 of the 2010 Florida Building Code, Energy Conservation, meets or exceeds ASHRAE Standard 90.1-2007, Energy Standard for Buildings, Except Low-Rise Residential Buildings for buildings other than low-rise residential.
The Florida Building Commission, which has statutory authority to administer the Florida Building Code (s. 553.72(3), Florida Statutes), hereby certifies that Chapter 4 of the 2010 Florida Building Code, Energy Conservation meets or exceeds the 2009 edition of the International Energy Conservation Code for low-rise residential buildings.
The International Energy Conservation Code (IECC) prototype building models (prototype models) were developed by Pacific Northwest National Laboratory (PNNL), in support of DOE's Building Energy Codes Program (BECP), to simulate energy savings associated with changes in energy codes and standards. For residential buildings, PNNL utilized two base prototypes to simulate both Single-family detached house, and Multi-family low-rise apartment building types. Energy models for the 2006, 2009 and 2012 versions of the IECC are available for each state.
This set of IECC Prototype Building Models is for the state of Florida, using the 2006 IECC as the baseline code.
Each ZIP file includes EnergyPlus model input files (.idf) and corresponding output files (.html).
This analysis of residential energy code compares the requirements of the 2009 International Energy Conservation Code (IECC) with the residential code—or typical construction practice in the absence of a code—in most states as of June 2009. The results, which include estimated typical energy savings of updating each state’s code to the 2009 IECC, are provided in chapters specific to each state.
Several states have either not adopted a mandatory energy code or developed their own codes which have minimal or no connection to the IECC. The latter—including California, Florida, Oregon, and Washington— were not included in this analysis because the codes in these states would be difficult to appropriately compare to the 2009 IECC and most of these states have energy offices that have already assessed the IECC on their own.
These analyses evaluate the cost-effectiveness of the prescriptive path of the 2015 edition of the International Energy Conservation Code (IECC), relative to the 2006 IECC for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, town-homes, and low-rise multifamily residential buildings covered by the residential provisions of the 2015 IECC. These reports were originally published in October 2015, and updated in February 2016 to update numbers reported in certain results tables.
