(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 m
2
)
or
less may have a maximum glass to CFA of 50 percent.
(3)
A-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).
