Lengthy IECC Debates Lead to Disapproval of EC14
Debates went past 2 a.m. Monday morning, but in the end the Advanced
Building Coalition (ABC) defeated the Energy Efficient Codes Coalition's
(EECC) International Energy Conservation Code (IECC) E14 proposal and
its companion appendix. Thom Zaremba represented the ABC, which consists
of the Association of Industrial Metalized Coaters & Laminators -
Window Film Committee; the International Window Film Association; The
Aluminum Extruders Council; APA; Nu-Wool Co. Inc.; Pilkington North America
Inc.; AGC Flat Glass North America Inc.; Icynene Inc.; Craig Conner, Building
Quality; and, Birch Point Consulting. The group's objective is to promote
a significant, cost-effective increase in building energy efficiency and
sustainability.
The EECC's website says EC14 was proposed to "boost the energy efficiency
of the 2009 IECC by 30 percent over the current model code." EC 14
has been dubbed by EECC as "The 30 Percent Solution."
EC 14 proposed changing fenestration U-factors for climate zones one through
four. Opponents said this would create inconsistencies with the International
Residential Code (IRC).
According to hearing documents, the ABC opposed EC14, as it represented
an "effort on the part of its proponents to actually introduce inconsistencies
into the ICC family of codes
while we strongly support a cost-effective
increase in the building energy codes, the proposed 'solution' in EC14
is flawed." Comments from ABC in the documents said, "as part
of a strategy to eliminate the energy provisions from the IRC, the proponents
of EC14 did not submit a single corresponding change to Chapter 11 of
the IRC. Both the IRC and IECC are widely used, and deviations between
the two codes will create confusion and enforcement complications.
Other reasons ABC opposed EC14 included:
- Structural and Life Safety Issues: The ABC claimed that the
energy codes must be viewed in conjunction with the building codes,
recognizing the importance of other building constraints such as life
safety and structural requirements. The group argued that several components
of EC14 did not account for these issues, specifically, by ignoring
the different considerations for hurricane impact windows and wall-bracing
design.
- Product Specificity: ABC representatives spoke in opposition,
saying the proposed code changes must be non-proprietary. The group
said EC14 would introduce code provisions that would give certain products
a competitive advantage in the marketplace, reducing significantly the
flexibility otherwise afforded by the IECC's alternate performance path.
- Cost Effectiveness: ABC representatives commented that during
committee hearings, EC14 proponents did not provide any detailed analysis
of the cost impact of this proposal. Thos speaking in opposition spoke
of the importance of cost effectiveness and affordability in terms of
a building code's adoptability. Testimony at the committee hearing demonstrated
unacceptably long payback periods for EC14 and its component proposals,
according to ABC comments.
- Procedural Flaws: ABC's comments noted that EC14 proposed more
than 100 additions and deletions to the existing code, and that Rule
3.3.4 of CP# 28-05 provides that: "Proposals which add or delete
requirements shall be supported by a logical explanation which clearly
shows why the current code provisions are inadequate or overly restrictive,
specifies the shortcomings of the current code provisions and explains
how such proposals will improve the code." ABC claimed that the
proponent's statement in support its code changes does not provide any
information required by Rule 3.3.4 and, as such "neither the committee
nor the ICC membership should be put to the burden of analyzing lengthy,
complex proposals that contain multiple parts to determine whether each
facet of the proposed change is technically justified."
