~~**102.4 Equipment labeling.** Heating, cooling and service water
heating equipment with equipment efficiency regulated as an AFUE, HSPF,
SEER or EF shall have the efficiency specified on a permanent
factory-applied nameplate.~~

> ~~**Exception:** Equipment assembled in the field.~~

[**103.1.1 Above code programs.** The code official or other authority
having jurisdiction shall be permitted to deem 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 shall be considered in compliance with this code.]{.underline}

[**402.2.2 Ceilings without attic spaces.** Where Section 402.1 would
require insulation levels above R-30 and the design of the roof/ceiling
assembly does not allow sufficient space for the required insulation,
the minimum required insulation for such roof/ceiling assemblies shall
be R-30. This reduction of insulation from the requirements of Section
402.1 shall be limited to 500 ft^2^ of ceiling area.]{.underline}

**402.2.4 Steel-frame ceilings, walls and floors.** Steel-frame
ceilings, walls and floors shall meet the insulation requirements of
Table 402.2.4 or shall meet the ~~wall~~ U-factor requirements in Table
402.1.2. The calculation of the U-factor for a steel-frame ~~wall~~
[envelope assembly]{.underline} shall use a series-parallel path
calculation method.

**402.5.1 Maximum fenestration U-factor and SHGC. ** The [area-weighted
average]{.underline} maximum fenestration U-factor permitted using
tradeoffs from Section 402.1.3 or Section 404 in zones 4 through 8 shall
be 0.40.  The [area-weighted average]{.underline} maximum fenestration
SHGC permitted using tradeoffs from section 404 in zones 1 through 3
shall be 0.50.

~~**403.1.2  Heat pump auxiliary heat.** Heat pumps having supplementary
electric resistance heaters shall have controls that prevent heater
operation when the heating load is capable of being met by the heat
pump. Except when necessary to assist the heat pump operation,
supplemental heater operation is not only allowed except during outdoor
coil defrost cycles not exceeding 15 minutes.~~

**8)** **[REASON]{.underline} (State reason and provide substantiation
to support the Comment):**

The U.S. Department of Energy (DOE) has worked for the past decade to
promote the International Energy Conservation Code (IECC). In response
to repeated comments that the residential IECC was difficult to
understand and implement, and expensive to enforce, DOE worked
extensively with many interested parties to develop a more usable energy
code. The result was EC48, a revision to the energy code replacing the
first six chapters of the IECC and the energy chapter of the
International Residential Code (IRC). At this fall's Code Development
Hearings (the "first hearing"), this improved energy code was approved
overwhelmingly for both the IECC and the IRC by votes in five ICC
committees. The result of the first hearing is a much more usable energy
code.

Aligning the IECC and IRC was one goal of DOE's original change
proposal. Most of DOE's public comment for the Final Action Code Hearing
(the "second hearing") is designed to realign the IECC and IRC where
floor amendments at the first hearing were made to one I-code and not
the other. Nothing proposed herein makes a substantial modification to
any major part of EC48. A few of the changes here correct editorial
errors.

Because the focus of this public comment is consistency between the IECC
and IRC, the same reason is being submitted for both the IECC and IRC.
The individual changes are discussed roughly in the order they occur in
the code, as approved at the first hearing.

[Default fenestration U-factors and SHGC]{.underline}.

EC48 proposed a more usable and condensed set of fenestration defaults
for U-factor and SHGC. In the first hearing, the EC48 default window
U-factor and SHGC tables for unrated products were replaced by amendment
in both IECC and IRC with the existing 2003 IECC tables. In the IECC
(only), the 2003 IECC default door U-factors were also restored. In
seeking ways to align the I-codes DOE has learned that the proponents of
those amendments desired default tables with more product categories
than EC48 originally proposed. This public comment includes streamlined
default tables that add additional product types not originally in EC48
(thermally broken windows, door table in the IRC), track the existing
defaults more closely for skylights, better cover the range of doors
(originally only covered doors 1.75 inches thick), eliminate some
uncertainty in the SHGC table (dependency on the glass color), and are
formatted to better fit the simplicity of EC48. (Replaces IECC Tables
102.1.3(1), 102.1.3(2), and 102.1.3(3). Replaces IRC Tables N1101.5(1)
and N1101.5(2). Conforming modification made to the text referencing the
table in IRC N1101.5.)

[Efficiency label on HVAC equipment]{.underline}.

The EC48 requirement for a permanent efficiency label on HVAC equipment
probably created a conflict with FTC rules and was eliminated by
amendment in the IRC. DOE's proposed second-hearing change removes the
same requirement from the IECC. (Removes IECC 102.4.)

[Above code program recognition]{.underline}.

The EC48 provision giving explicit authority for a jurisdiction to
recognize above-code energy-efficiency programs was removed in the IECC,
but retained in the IRC. DOE's proposed second-hearing change makes the
IECC and IRC consistent by restoring the explicit option in the IECC.
(Add IECC 103.1.1.)

[Certificate location]{.underline}.

A minor discrepancy on where the certificate on home energy efficiency
features should be posted was introduced by a first-hearing amendments.
The IRC is modified to match the IECC. (Modify IRC N1101.8.)

[Cathedral ceiling exemption]{.underline}.

In EC48 the requirement for ceiling insulation greater than R-30 was
relaxed to R-30 where framing members are too small to fit the full
height of the insulation. In the first hearing this exemption was
removed from the IECC, but retained in the IRC. DOE's proposed
second-hearing change is a compromise that limits the exemption to 500
ft^2^ in both codes. (Add IECC 402.2.2. Modify IRC N1102.2.2)

[Steel framing]{.underline}.

DOE's second-hearing change proposal makes editorial improvements in the
section on steel framing in both the IECC and IRC. (Modify IECC 402.2.4.
Modify IRC N1102.2.4.)

[Impact resistant fenestration]{.underline}.

EC48 exempted impact resistant fenestration from the U-factor
requirements in some zones because commercial products were generally
lacking. A first-hearing amendment removed the exemption from the IECC,
but not the IRC. Because commercial products are now available, DOE
proposes that the exemption be removed from the IRC. (Delete IRC
N1102.3.7.)

[Prescriptive HVAC tradeoffs]{.underline}.

The EC48 prescriptive HVAC tradeoffs were deleted in the IECC and
reduced in the IRC. To make the two codes consistent, DOE proposes that
the remaining table and associated text be deleted from the IRC. (Delete
IRC N1102.1.4 and Table N1102.1.4.)

[Maximum fenestration tradeoffs]{.underline}.

The section is clarified in both codes to require an "area-weighted
average". (Modify IECC 402.5.1. Modify IRC N1102.5.1)

[Heat pump controls text]{.underline}.

Confusing 2003 IECC language on heat pump controls was changed by an
unrelated first-hearing code change (EC17). This had the effect of
resurrecting text that had been deleted as unnecessary in the context of
DOE's first-hearing change proposal. No comparable text was added to the
IRC; therefore the IECC section affected by EC17 should be deleted.
(Delete IECC 403.1.2.)

[Window and Skylight U-factors]{.underline}.

Prescriptive window and skylight U-factor requirements in EC48 were
modified in the south by a first-hearing floor amendment in the IECC.
However, only one table of two that govern the U-factors was modified.
The window U-factor changes were small, designed to better accommodate
aluminum frames. The southern skylight U-factors were lowered,
consistent with DOE's goal of better accommodating cooling concerns in
the energy code. DOE's second-hearing proposal is to make the other IECC
table and the two IRC tables consistent with the first-hearing IECC
floor changes. (Modify fenestration and skylight U-factors in IECC Table
402.1.2; and IRC Tables N1102.1 and N1102.1.2.)

[Southern basement insulation]{.underline}.

A southern climate zone in EC48 was amended to require basement
insulation in the IECC, but not the IRC. Because basement insulation is
of marginal value in much of this zone, DOE is proposing that the IECC
and IRC be made consistent by removing the IECC basement insulation
requirement in zone 3. (Modify zone 3 basement insulation IECC Table
402.1.)

[Insulation values changed]{.underline}.

DOE is proposing a few changes to both the IECC and IRC for reasons of
practicality. The floor insulation requirement in zone 5 of R-25 should
become R-30. This will eliminate the only occurrence of R-25 in the
code. Note that the higher value, per the table footnote, would not be
required if it caused an increase in framing size. (Modify zone 5 floor
values in IECC Tables 402.1 and 402.1.2. Modify zone 5 floor values in
IRC Tables N1102.1 and N1102.1.2.)

R-15 foundation insulation may lead to a thick outside "lip" which is
difficult to protect, so DOE is proposing that basement and slab
insulation requirements be reduced to R-10 in the extreme northern
zones. (Modify zone 7/8 basement and slab R-values in IECC Tables 402.1
and 402.1.2. Modify zone 7/8 basement U-factors in Tables N1102.1 and
N1102.1.2.)

[U-factor table discrepancies]{.underline}.

Unintentional discrepancies were introduced into IECC and IRC tables by
a first-hearing floor amendment, making mass-wall U-factors more
stringent than frame-wall U-factors in northern zones. These mass-wall
U-factors should be set equal to the corresponding frame-wall U-factors.
(Modify mass wall U-factors in IECC Table 402.1.2 and IRC Table
N1102.1.2)

A discrepancy in the U-factor tables for crawl space walls was also
introduced in a first-hearing IECC floor amendment. No discrepancy was
introduced into the IRC. (Modify zone 7/8 crawl space wall U-factor in
IECC Table 402.1.2)

[Performance approach window area]{.underline}.

One element of the EC48 performance calculation (IECC only), the
standard-design window area, was changed by floor amendment in the first
hearing. DOE proposes that the IECC revert to the original proposed
value (18% of conditioned floor area) to maintain consistency with
several beyond-code programs that tend to make use of the same or
similar software as is used for performance-based code compliance.
(Modify IECC Table 404.5.2(1).)

[Unvented crawl space text]{.underline}.

Editorial improvements are proposed to the section on unvented crawl
spaces. (Modify IRC R408.2.)

[Commercial climate zone changes]{.underline}.

Two successful commercial IECC changes (EC37 and EC40) modified text
that included climatic references (HDD). Those two changes should be
translated into the new climate zones, but otherwise unchanged. (Modify
IECC 803.2.5.1 and 803.3.10.)
