Scope: Compliance with Section R402.1.2 of the Florida Building Code, Energy Conservation, shall be demonstrated by the use of Form
8402 for single- and multiple -family residences of three stories or less in height, additions to existing residential buildings, alterations,
renovations and building systems in existing buildings, as applicable. To comply, a building must meet or exceed all of the energy efficiency
requirements and applicable mandatory requirements summarized on this form. It a building does not comply with this method, or by the UA
Alternative method, it may still comply under Section R405 or 8406 of the Florida Building Code, Energy Conservation.
General I n structi ons:
1. Fill in all the applicable spaces of the "INSTALLED" row In the INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENT table with the
information requested. All 'INSTALLED" values must be equal to or more efficient than the required levels. "AVG" Indicates an area weighted
average is allowed; "LOWEST" indicates the lowest R -value to be inetalled must be entered.
2. Complete the tables for air infiltration and installed equipment.
3. Read the MANDATORY REQUIREMENTS table and check each box to indicate your intent to comply with all applicable Items.
4. Read, sign and date the "Prepared By" certification statement at the bottom of this form. The owner or owner's agent must also sign and date the
form.

0) R -values are minimums. LA -factors and SHGC are maximums. When insulation is installed in a cavity which is less than the label or design thickness of the
insulation, the instalted ci-value of the insulation shall not be less than the R -value specified in thetable.
(2) The fenestration U -factor column excludes skylights. The SHGC column applies to all glazed fenestration. Exception: Skylights may be excluded from glazed
fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGC for such skylights does not exceed 0.30.
(3) For impact rated fenestration complying with Section 8301.2.1.2 of the Florida Building Code, Residential or Section 1609. 1,2 of the Florida Building Cade,

and up to 15 square feet of glazed fenestration area are exempted from the bLiactor and SHGC requirement based on Section R402.3.1, R402.3.2 and
R402.3.3.
(4) One side -hinged opaque door assembly up to 24 square feet is exempted from this Lf -factor requirement based on Section R402.3.4.
(5) R -values are for insulation material only as applied in accordance with manufacturer's installation instructions.
16) The second R -value applies when more than Half the insulation is on the interior of the mass wall.
7) R-5 shall be added to the required siab edge R -values for heated slabs. Insulation depth shall be the depth of the fooling or 2 feet, whichever is less in Climate
Zones 1 through 3 for heated slabs.
