Residential Building Thermal Envelope Approach
FORM R402=2017 Climate Zone ❑
Scope: Compliance with Section R401.2(1) of the Florida Building Code, Energy Conservation, shall be demonstrated by the use of Form
R402 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 on Table R402A and all applicable mandatory requirements summarized in Table R402B of this form. If a building does not
comply with this method, or by the UA Alternative method, it may still comply under Section R405 of the Florida Building Code, Energy
Conservation.

(1) Each component present in the As Proposed home must meet or exceed each of the applicable performance criteria in order to comply with this code using
this method.
(2) For impact rated fenestration complying with Section R301.2.1.2 of the Florida Building Code, Residential or Section 1609.1.2 of the Florida Building Code,
Building, the maximum U-factor shall be 0.65 in Climate Zone 2. An area -weighted average of U-factor and SHGC shall be accepted to meet the
requirements, or up to 15 square feet of glazed fenestration area are exempted from the U-factor and SHGC requirement based on Sections R402.3.1,
R402.3.2 and R402.3.3.
(3) One side -hinged opaque door assembly up to 24 square feet is exempted from this U-factor requirement.
(4) R-values are for insulation material only as applied in accordance with manufacturer's installation instructions. For mass walls, the "interior of wall"
requirement must be met except if at least 50 percent of the insulation required for the "exterior of wall" is installed exterior of, or integral to, the wall.
(5) Ducts & AHU installed "substantially leak free" per Section R403.3.2. Test required 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), Florida Statutes. The total leakage test is not required for ducts and air
handlers located entirely within the building thermal envelope.
(6) Minimum efficiencies are those set by the National Appliance Energy Conservation Act of 1987 for typical residential equipment and are subject to NAECA
rates and regulations. For other types of equipment, see Tables C403.2.3(1-11) of the Commercial Provisions of the Florida Building Code, Energy
Conservation.
(7) For other electric storage volumes, minimum EF = 0.97 - (0.00132 * volume).
(8) For other natural gas storage volumes, minimum EF = 0.67 - (0.0019 * volume).
