(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;
otherwise Section 405 compliance must be used.
(2) Windows and doors qualifying as glazed fenestration areas must comply with both the maximum U- Factor and the maximum SHGC (solar Heat Gain Coefficient) criteria
and have a maximum total window area equal to or less than 20% of the conditioned floor area (CFA); otherwise Section 405 must be used for compliance.
Exception: Additions of 600 square feet (56 m2) or less may have a maximum glass to CFA of 50 percent.
(3) 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% of the R -6 insulation required for the "exterior of wall" is installed exterior of, or integral to, the wall.
(4) Ducts & AHU installed substantially leak free per Section 403.2.2.1. Test by Class 1 BERS rater required.
Exception: Ducts installed onto an existing air distribution system as part of an addition or renovation; duct must be R -6 installed per Sec. 503.2.7.2.
(5) For all conventional units with capacities greater than 30,000 Btu /hr. For other types of equipment, see Tables 503.2.3(1 -8).
Exception: The prohibition on electric resistance heat does not apply to additions, renovations and new heating systems installed in existing-'buildings.
(6) For other electric storage volumes, minimum EF - 0.97 - (0.00132 x volume).
(7) For other natural gas storage volumes, minimum EF = 0.67 - (0.0019 x volume).
