Atlantic Beach, FL 32233
MANDATORY REQUIREMENTS - See individual code sections for full details.
SECTION R401 GENERAL
The building official shall require that an energy performance level (EPL)R401.3 Energy Performance Level (EPL) display card (Mandatory).
display card be completed and certified by the builder to be accurate and correct before final approval of the building for occupancy. Florida law
(Section 553.9085, Florida Statues) requires the EPL display card to be included as an addendum to each sales contract for both presold and
nonpresold residential buildings. The EPL display card contains information indicating the energy performance level and efficiencies of components
installed in a dwelling unit. completed and signed by the builder The building official shall verify that the EPL display card accurately reflects the
plans and specifications submitted to demonstrate compliance for the building. A copy of the EPL display card can be found in Appendix RD.
SECTION R402 BUILDING THERMAL ENVELOP
The building thermal envelope shall be constructed to limit air leakage in accordance with the requirements ofR402.4 Air leakage (Mandatory).
Sections R402.4.1 through R402.4.5.
Dwelling units of R-2 Occupancies and multiple attached single family dwellings shall be permitted toException:
comply with Section C402.5.
The building thermal envelope shall comply with Sections R402.4.1.1 and R402.4.1.2. The sealingR402.4.1 Building thermal envelope.
methods between dissimilar materials shall allow for differential expansion and contraction.
The components of the building thermal envelope as listed in Table R402.4.1.1 shall be installed in accordanceR402.4.1.1 Installation.
with the manufacturer’s instructions and the criteria listed in Table R402.4.1.1, as applicable to the method of construction. Where required
by the code official, an approved third party shall inspect all components and verify compliance.
The building or dwelling unit shall be tested and verified as having an air leakage rate not exceeding seven air changesR402.4.1.2 Testing.
per hour in Climate Zones 1 and 2, and three air changes per hour in Climate Zones 3 through 8. Dwelling units with an air leakage rate less
than three air changes per hour shall be provided with whole-house mechanical ventilation in accordance with Section R403.6.1 of this code
and M1507.3 of the Florida Building Code, Residential. Testing shall be conducted in accordance with ANSI/RESNET/ICC 380 and reported at a
pressure of 0.2 inch w.g. (50 pascals). Testing shall be conducted by either individual as defined in Section 553.993(5) or (7), Florida Statutes,
or individuals licensed as set forth in Section 489.105(3)(f), (g) or (i) or an approved third party. A written report of the results of the
test shall be signed by the party conducting the test and provided to the code official. Testing shall be performed at any time after creation
of all penetrations of the building thermal envelope.
Testing is not required for additions, alterations, renovations, or repairs, of the building thermal envelope of existingException:buildings in which the new construction is less than 85 percent of the building thermal envelope.
During testing:
1. Exterior windows and doors, fireplace and stove doors shall be closed, but not sealed, beyond the intended
weatherstripping or other infiltration control measures.
2. Dampers including exhaust, intake, makeup air, backdraft and flue dampers shall be closed, but not sealed beyond
intended infiltration control measures.
3. Interior doors, if installed at the time of the test, shall be open.
4. Exterior doors for continuous ventilation systems and heat recovery ventilators shall be closed and sealed.
5. Heating and cooling systems, if installed at the time of the test, shall be turned off.
6. Supply and return registers, if installed at the time of the test, shall be fully open.
7. If an attic is both air sealed and insulated at the roof deck, interior access doors and hatches between the conditioned space volume
