Mandatory Requirements for Residential Performance, Prescriptive and ERI Methods
ADDRESS:2020 Vela Norte Cir Permit Number:
Atlantic Beach, FL 32233
MANDATORY REQUIREMENTS - See individual code sections for full details.
SECTION R401 GENERAL
R401.3 Energy Performance Level (EPL) display card - (Mandatory). The building official shall require that an energy performance level
(EPL) 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 Statutes) 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. The building official shall verify that the EPL display card completed and signed
by the builder accurately reflects the plans and specifications submitted to demonstrate code compliance for the building. A copy of the
EPL display card can be found in Appendix RD.
SECTION R402 BUILDING THERMAL ENVELOPE
R402.2.10.1 Slab-on-grade floor insulation installation (Mandatory). Where installed, the insulation shall extend downward from
the top of the slab on the outside or inside of the foundation wall. Insulation located below grade shall be extended the distance
provided in Table R402.1.2, or the distance of the proposed design as applicable, by any combination of vertical insulation, insulation
extending under the slab or insulation extending out from the building. Insulation extending away from the building shall be protected
by pavement or by not less than 10 inches (254 mm) of soil. The top edge of the insulation installed between the exterior wall and the
edge of the interior slab shall be permitted to be cut at a 45-degree (0.79 rad) angle away from the exterior wall.
R402.2.11.1 Crawl space walls insulation installation (Mandatory). Where crawl space wall insulation is installed, it shall be
permanently fastened to the wall and extend downward from the floor to the finished grade level and then vertically and/or horizontally
for at least an additional 24 inches (610 mm). Exposed earth in unvented crawl space foundations shall be covered with a continuous
Class I vapor retarder in accordance with the Florida Building Code, Building, or Florida Building Code, Residential, as applicable. All
joints of the vapor retarder shall overlap by 6 inches (153 mm) and be sealed or taped. The edges of the vapor retarder shall extend
not less than 6 inches (153 mm) up the stem wall and shall be attached to the stem wall.
R402.4 Air leakage (Mandatory). The building thermal envelope shall be constructed to limit air leakage in accordance with the
requirements of Sections R402.4.1 through R402.4.5.
E x c e p t i o n : Dwelling units of R-2 Occupancies and multiple attached single family dwellings shall be permitted to
comply with Section C402.5.
R402.4.1 Building thermal envelope. The building thermal envelope shall comply with Sections R402.4.1.1 and R402.4.1.2.
The sealing methods between dissimilar materials shall allow for differential expansion and contraction.
R402.4.1.1 Installation. The components of the building thermal envelope as listed in Table R402.4.1.1 shall be installed in accordance
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.
R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage rate not exceeding seven air
changes 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 Section 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
individuals 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.
E x c e p t i o n : Testing is not required for additions, alterations, renovations, or repairs, of the building thermal envelope of existing
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

R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage rate not exceeding seven air changes
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 Section M1507.3 if 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 individuals as defined in Section 553.993(5) or (7),
Florida Statues,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.
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, back draft and flue dampers shall be closed, but not sealed beyond intended infiltration control
m e a s u r e s .
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 sealed and insulated at the roof deck, interior access doors and hatches between the conditioned space volume and the
attic shall be opened during the test and the volume of the attic shall be added to the conditioned space volume for purposes of reporting
the infiltration volume and calculating the air leakage of the home.
