Fifth Edition Florida Energy Conservation Changes
By Amy Yelverton, Chairwoman, Government Relations Committee
Below are some of the changes for the Florida Building Codes that will go into effect July 1, 2015. I have listed several websites that contain more in-depth information on the codes.
The main change as it affects the window industry will be the enforcement of a new Energy Code for Florida.
• The 30% rule has been clarified and will now be null and void.
• All replacement products will now have to meet the energy code. No exceptions.
• New construction will have a choice for following the performance path for compliance or the prescriptive path.
What does this mean? …
Zone 1 (Dade, Broward, Monroe, Palm Beach, Collier, Lee, Hendry Counties)
Non-Impact windows U .65 SHGC .25
• Aluminum will still be available but will be Insulated High Performance LowE. No option for Monolithic glass in non-impact windows,
• Vinyl will be more widely introduced into the market to meet codes.
Impact windows U .75 SHGC .25
• Aluminum will still be available but most manufacturers will have to use Insulated Impact – High Performance LowE.
• Vinyl will be more widely introduced into the market. Limitation will be structural DP Ratings.
