The Commission is Responsible for: Updating the Florida Building Code Triennially Based on National Model Codes and Standards Modifying Base Codes to Address Florida Specific Needs Interpreting the Code Declaratory Statements (standard Chapter 120, F.S.) Binding Interpretations (special appeal authority) Maintaining a Product Approval System One Stop Approval that is Optional for Manufacturers
Florida Building Code Includes Multiple Volumes Building Residential Existing Building Plumbing Mechanical Fuel Gas Electrical Energy and Accessibility Coordinated with the Florida Fire Prevention Code
The Florida Energy Code Established in 1980 by combining Thermal Efficiency Standards and Lighting Efficiency Standards from 1979 law Statewide uniform and mandatory code Parallels national model codes for commercial and residential buildings ASHRAE 90.1 and MEC/IECC Will take the IECC format for the 2010 Code but retain Florida efficiencies
New Goals for Increasing Building Efficiency Standards Governor Crist s 2007 Executive Order 127 Directed: 15% Increase in Building Efficiency Standards Implemented via 2009 Supplement to 2007 Energy Code 2008 Law Directs Improvements Relative to the 2007 Code: 20% Increase in Efficiency Standards by 2010 Code (includes Governor Crist s 15% so net increase of 5% over 2009 Supplement) 30% Increase by 2013 Code 40% Increase by 2016 Code 50% Increase by 2019 Code
Impact of the Florida Energy Code 1980 2009 Space heating and cooling energy have been reduced most.

20% Improvement by the 2010 Code Using conventional building envelope component efficiency upgrades only would require The cost effective limits of insulation The reasonable technology limits for window efficiency
30% Improvement by the 2013 Code Using conventional building envelope component efficiency upgrades only would require Cost effective limits of insulation Technology limits for windows Plus Combination of Reduced window area AC ducts moved into conditioned space (W&D) Window Area 12% Ducts in Conditioned Space
50% Improvement by the 2019 Code Using conventional building envelope component efficiency upgrades only would require Cost effective limits of insulation Technology limits for windows Plus Combination of Reduced window area AC ducts moved into conditioned space Plus Equipment efficiencies higher than current federal minimums

Obstacles to 50% More Efficiency Mild climate means increased insulation levels and window efficiencies are providing diminished benefits Reaching the limits of cost effective improvements to building envelope components Reducing heat gain and controlling indoor humidity for Indoor Air Quality are at odds Competing Wind and Energy performance for windows Federal appliance efficiency law constrains states from prescribing efficiencies higher than federal minimums. Resistance to change for construction practices such as placement of AC ducts, high efficiency windows, window area, and alternative AC and water heating systems.
What Are the Opportunities and Solutions INNOVATION INCENTIVES EDUCATION Florida s Performance Based Energy Code promotes Innovation and Market Competition Prescriptive Codes are Simplistic, Constrained and A Difficult Regulatory Approach to Incentivizing Change in the Marketplace Education is the KEY to Effective Performance Codes
Character and Roles of Florida s Commissions in Building Energy Conservation Florida Building Commission Maintains and Updates the Energy Provisions of the Building Code The FBC is Dominated by Construction Industry Professionals Similar to Licensing Boards The Florida Energy and Climate Commission is a Broad Based Board Responsible for Florida s Energy Policy The FECC Administers Federal Funds Directed to Support of State Energy Programs
What Role Can the FECC Have in Building Energy Efficiency Regulation The FECC can participate in development of the Florida Energy Code The Building Commission establishes formal coordination with many state agencies for Code development Advocacy for State energy policy interests would provide balance The FECC can provide a stable source of federal funds to support development and implementation of the Energy Code Research Education Measurement of Code effectiveness
Current FECC Support for Codes The State provided training on the Florida Energy Code for its first twenty years and large scale measurement during that time demonstrated its effectiveness The Building Commission s staff and funding resources are diluted in management of the many codes it is responsible for The FECC is providing ARRA EECBG funds for two years The ARRA required states to adopt, to provide training, and to measure compliance/effectiveness of Energy Codes
Thoughts to Leave You With Coordination and Cooperation of State Agencies is A Key to Effective Government The Florida Energy Office and Federal Funds Played an Important Role in the Effectiveness of the Florida Energy During the 1980 s and 1990 s and Can Again The Florida Building Commission Welcomes and Accomodates Participation of State Agencies in the Development of the Florida Building Code
