N1101.16, tables N1101.10, and N1101.10.2(2) are amended and figure N1101.10a
of the code is added to read as follows:
N1101.3.1 (R101.4.3). Additions, alterations,
renovations, or repairs. Additions, alterations, renovations, or repairs to an
existing building,
building system, or portion thereof shall conform to the
provisions of this
code as they relate to
new construction without requiring
the unaltered portion(s) of the
existing building or
building system to comply
with this
code. Additions, alterations, renovations, or repairs shall not
create an unsafe or
hazardous condition or overload
existing building systems.
An addition shall be deemed to comply with this
code if the addition alone
complies or if the
existing building and addition comply with this
code as a
single
building.
Exception: The following are exempt provided the energy
use of the building is not increased:
1. Storm windows installed over existing
fenestration.
2. Glass only
replacements in an existing sash and frame.
3. Existing ceiling, wall, or floor cavities
exposed during construction provided that these cavities are filled with
insulation.
4. Construction where
the existing roof, wall, or floor cavity is not exposed.
5. Reroofing where the roof is part of the
thermal envelope, and where neither the roof sheathing nor the roof insulation
is exposed.
6. Reroofing where the
roof is not part of the thermal envelope.
7. Replacement of existing doors that
separate conditioned space from the exterior shall not require the installation
of a vestibule or revolving door, provided, however, that an existing vestibule
that separates a conditioned space from the exterior shall not be
removed.
8. Alterations that
replace less than 50% of the luminaries in a space, provided that such
alterations do not increase the installed interior lighting power.
9. Alterations that replace only the bulb and
ballast within the existing luminaries in a space provided that the alteration
does not increase the installed interior lighting power.
N1101.7 (R102.1.1). Above code programs. The
state construction code commission may evaluate and approve a national, state,
or local energy efficiency program to exceed the energy efficiency required by
this code. Buildings approved in writing by such an energy efficiency program,
such as ICC 700-2012 "silver" or energy star version 3 (rev. 07), shall be
considered in compliance with this code. The requirements identified as
"mandatory" in chapter 4 shall be met.
N1101.10 (R301.1). Climate zones. Climate
zones from figures 301.1, 301.1a or table 301.1 shall be used in determining
the applicable requirements of this code.
N1101.12.3. Fenestration product rating.
U-factors of fenestration products (windows, doors, and skylights) shall be
determined in accordance with NFRC 100 by an accredited, independent
laboratory, and
labeled and
certified by the manufacturer. Products lacking
such a
labeled U-factor shall be assigned a default U-factor from table
N1101.12.3(1) or N1101.12.3(2).
Exception: Computer simulations by independent NFRC
certified laboratories or approval under section 21 of 1972 PA 230, MCL
125.1521 is considered in compliance with this section.
N1101.16 (R401.3). Certificate (mandatory). A
permanent certificate shall be posted on or in the electrical distribution
panel, and shall meet all of the following:
(a) Be affixed or attached so it does not
cover or obstruct the visibility of the circuit directory label, service
disconnect label, or other required labels.
(b) Be completed by the builder or registered
design professional.
(c) List the
predominant R -values of insulation installed in or on
ceiling/roof, walls, foundation (slab, basement wall, crawlspace wall and/or
floor) and ducts outside conditioned spaces and U- factors for fenestration. If
there is more than 1 value for each component, then the certificate shall list
the value covering the largest area.
(d) List the types and efficiencies of
heating, cooling, and service water heating equipment.
(e) If a gas-fired unvented
room heater,
electric furnace, or baseboard electric heater is installed in the residence,
then the certificate shall list "gas-fired unvented
room heater," as
appropriate. An efficiency shall not be
listed for gas-fired unvented
room
heaters, electric furnaces, or electric baseboard heaters.
