Original Request

  • Requested By: Brian Law
  • Requester E-Mail: blaw@cityofsab.org
  • Code Version: 2021
  • Code: ENERGY
  • Code Description:
  • Chapter:
  • Section: R503.1.1.1
  • Topic: Replacement Fenestration

  • Question: Is it the intent of section R503.1.1.1 to require replacement fenestration products in R-2 occupancies to comply with the minimum SHGC of 0.25 and minimum U factor of 0.40 for a climate zone 2 area. The project is for replacement of all windows and doors in a single unit in an existing condominium complex.

Answer:

If the building is considered a "renovated building" defined as; estimated costs exceed 30% of assessed value of the structure, (see R101.4.2 and Definitions in chapter 2) then the replacement fenestration products need to meet a maximum SHGC of .25 and a maximum U factor of .40 for a building in climate zone 2 (see Table 402.1.2 note a.) if it is an existing building and not considered a renovated building then it is exempt from the provisions of the Energy Code

Commentary:

In 1992, the Florida Legislature passed the wording in F.S. 553.902 (6) and 553.903 which was then carried over into Code language which exempts structures that are being altered when the value of the work does not exceed the 30% threshold.
