(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 0.75 in Climate Zone 1 and 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 manufacturers’ 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 R403.2.2. Test required by an energy rater certified in accordance with Section 553.99, Florida Statutes, or as authorized by 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 rules 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, min. EF = 0.97 - (0.00132 * volume).
(8) For other natural gas storage volumes, min. EF = 0.67 - (0.0019 * volume).
