REPORT TO. Kalispell Mayor and City Council
FROM: Jeff Clawson, Building Official
Jane Howington, City Manager
SUBJECT: Adoption of the 2009 International Energy Conservation Code
MEETING DATE: June 7 Council Meeting
BACKGROUND: The State of Montana has officially adopted the 2009 International Energy
Conservation Code effective March 26, 2010. As such the code applies to all
residentiallcomnnercial construction within the state of Montana. The City of Kalispell, in order to
maintain our certification with the State Building Codes division is required to follow suite locally
within 90 days and adopt the 2009 code as well.
Adoption of the code by the City of Kalispell will provide contractors a local source for education
and answers to questions about the code and its requirements. The Kalispell Building Department
will continue with an educational approach to achieving code compliance within the construction
industry with the adoption of all new codes.
Specific changes with the new Montana energy code include:
• Modest increase in wall and ceiling R-value of insulation,
• Windows need to be more efficient to protect against heat loss,
• At least one-half of the permanent light fixtures must have high efficiency light bulbs,
• Heating system ductwork located outside of the conditioned (heated) part of the house
must be tested for tightness.
• Programmable/setback thermostats are required in homes with furnaces.
• Basement walls must be insulated to prevent the loss of energy through those walls, a
stipulation that had a mixed reaction to the cost benefit of the regulation's requirement.
The statewide energy code also gives prospective house buyers an additional tool to use in
making their purchase decision -the "Energy Efficiency Components Label." This label is required
in all new houses and is the way for the builder to inform the house buyer of the insulation levels,
heating system efficiencies and other energy features of a new house. The label should be
permanently affixed to the home's electrical breaker box., so subsequent owners will have the
same information available to them.
In conclusion, a house built to the new code should use about 15% less energy than a similarly
sized one built to the old code and should be more resistant to moisture damage. The building
department will continue to be available to answer questions the development community may
have. In preparation for adoption of this code, the department did attend a community wide
training program with local builders hosted by the Flathead Builders Association. our department
did send out approximately 84 letters to builders in the community advising them of the new
changes. Finally, we have been working with builders over the past 6 months showing them the
upgrades and changes that will be required once the new code is adopted.
Recommendation: .Approve the attached ordinance adopting the 2009 edition of the
International Energy Conservation Code.
FISCAL EFFECTS: Minor cost increases will be experienced by homebuilders as they
seek to comply with the new standards. This is anticipated to be counter balanced by
increases in energy efficiency experienced by future homeowners. Note that while
most costs are minor, there has been some concern expressed with the insulating of
unfinished basement space. This issue is not anticipated to be significant in
Kalispell. Less than half of all houses are constructed with. basements. Basements
are not required to be finished, just insulated which typically includes draping the
insulation over the walls or insulating the outside of the foundation walls. The
majority of builders are already insulting the galls of unfinished basements.
Furthermore, when an owner does proceed with finishing off the basement either now
or in the fixture, the insulation will be in place for them to use to complete the
basement. The insulation is not lost or wasted.
AI,.'T ERNA Failure to adopt the ordinance would place the building
department out of compliance with the state building codes division. The energy code
would then be de facto administered by the state of Montana within the city limits of
Kalispell.

Re; Adoption of 2009 Montana Energy Code
Dear Jeff,
I would like to go on record as supporting the City's adoption of the 2009
Montana Energy Code.
As Construction Supervisor for US Rural Development sponsored, low
income, Mutual Self Help program, I keep our homes up to date with all
energy requirements and latest developments in the Northwest Energy Star
program. This requires that I budget for the materials and labor to meet
these requirements.
Our program has been building to Energy Star requirements for two years
and we have completed (16) qualified Energy Star homes to date. We are
currently under construction with another (16) homes that are being built
to Energy Star standards also.
As you may be aware, Energy Star requirements have been higher than the
Montana Energy Code requirements for some time now and the 2009
Montana Energy Code requirements will still not match the Energy Star
program requirements in every detail, but will come closer. If this low
income program can afford to meet the 2009 Montana Energy Code
requirement, certainly it shouldn't be a hardship for other builders.
We stand willing to lend our support to the City's adoption of the 2009
Montana Energy Code and would be happy to assist the City or any
builders and contractors in implementing these requirements.

BEFORE THE DEPARTMENT of LABOR AND INDUSTRY{
STATE OF III O N TA N A
In the matter of the amendment of ) NOTICE OF AMENDMENT
ARM 24.301.161, model energy code )
TO: All Concerned Persons
1. On October 29, 2009, the Department of Labor and Industry (department)
published MAR Notice No. 24-301-239 regarding the public hearing on the proposed
amendment of the above -stated rule, at page 1844 of the 2009 Montana
Administrative Register, issue no. 20.
2. On November 30, 2009, a public hearing was held on the proposed
amendment of the above -stated rule in Helena. Several comments were received
by the December 14, 2009, deadline.
3. The department has thoroughly considered the comments received, A
summary of the comments received and the board's responses are as follows:
COMMENT : Numerous verbal and written comments were received in response
to the proposed adoption of the International Code Council's 2009 edition of the
International Energy Conservation Code (IECC). Nearly all the comments were in
favor of the proposal to adopt the 2009 IECC code, but advocated more stringent
building requirements aimed at energy efficiency requirements than those set forth
by the 2009 IECC.
RESPONSE 1: The Montana Legislature, under 50-00--203, MCA, requires the
department to adopt rules that relate to the conservation of energy that are
consistent with and properly balance the public policy considerations set forth 50-50-
8017 MCA, namely, to protect and improve economic and environmental well-being
and energy security, while recognizing the basic need for safe and affordable
shelter. The department, through stakeholder meetings, has struck that balance and
will continue to cultivate stakeholder input for future determinations in energy code
development.
COMMENT 2: Of the comments in favor of the adoption of the 2009 code
mentioned above, there were six areas of focus. Numerous commenters joined in
support of the specific recommendations submitted by Jinn Baerg of Montana
Energy+Design (herein, "ME+D") and addressed by subject area below:
a. Basement Walls: The current rule allowed a delay in the insulation of basement
walls, until such time as the basement was actually finished for occupancy. The
proposed rule eliminates this so-called "basement exception" and will now require
insulation of basement walls to be completed at the time of construction and at an R-
value of 15 continuous or 19 cavity, as set forth in the 2009 IECC.
Montana Administrative Register 5-3/25f 10
-75 1 -
A majority of comments supported insulating the basement sooner, rather
than later. Others asked that a "more stringent" R--value be imposed, without
specifying what that would be. A commenter stated that that "the highest possible
basement insulation requirements" would result in an "optimum balance of energy
conservation, construction costs, and reasonable economic payback period."
Another commenter stated that a minimum of R-20 should be required on basement
and crawlspace walls, ring bands, and under basement slabs.
Response: The 2009 IECC allows two methods of basement insulation: R-15
applied continuous or R-1 9 applied in cavities. These R-values represent
consideration for currently available manufactured products and allow for the two
methodologies most often used in field construction. As manufacturing products
change and more varieties in field installation methods become apparent, the
department will evaluate those processes to allow a greater expansion of products,
methods, and R--values.
b. 1lvalls- The 2009 IECC requires R--20 code values for gall insulation. The
department proposes to increase that value to R-21. The ME+D urged setting the
value at R--25.
Response; The 2009 IECC dictates an R-value of wood framed galls to be R-20
(cavity). The department evaluated stakeholder input, including the study calling for
increases to R-25. The department concluded that moving to R--21 was most
prudent now, due to the manufacturer's product line being most conducive to this R-
21 value. As code development processes move forward, including stakeholder
input, the department will monitor the available products and methods becoming
available and gauge those products and RMvalue assemblies against the
department's responsibility for public welfare, as well as the financial impact such
code requirements have on construction costs and other economic factors.
c. Ceilings: Section 1(e) of the proposed rule change reduces the amount of ceiling
that is allowed to have a lower R-value (R-30) than that required in attic space (R-
49). Numerous commenters supported the proposal to reduce, the ceiling space,
and also supported the ME+D proposal to increase the ceiling space to R-49.
Response. The department recognizes the value of this comment and the increase
in code requirement, proposed by the department, is a great example of cultivating
and embracing informed comment on the subject. Presently, the 2009 IECC allows
500 square feet or 20 percent of the total insulated ceiling area to be reduced to R-
301 if the roof/ceiling assembly does not allow sufficient space.
The department, based on stakeholder input, struck a compromise between
current code language and the requested zero square feet or zero percent area of
reduced R-value. The department's result will still allow 250 square feet of reduced
R-value or ten percent of insulated ceiling area; this change results in a 100 percent
increase in area, now required to have full R-49 ceiling insulation.
0w3/2 5/10 Montana Administrative Register
- 752-
d. Windows: The 2009 IECC requires a U-factor of 35 for windows. BCB proposed
to require U-33. The ME+D proposal requested "tuned" windows, which would
specify window type and performance based on orientation of the window, with
relation to North, south, East or West. A commenter urged mandatory use of U-30
or less.
Response. After hearing stakeholder comment on this issue, the department
determined that setting window performance criteria for each side of the house
would be too confusing and troublesome for builders and homeowners. The
department was pleased that the Building Codes Council offered a compromise in
the form of a reduced U-factor specification to 0.33. The department concluded that
this is a good balance and feels that window manufacturers will have product
available in that U-factor.
e. Allowable Air Exchange: The 2009 IECC sets allowable air changes to 7ACH50
and allows a prescriptive list option. The proposed rule sets the allowable air
changes to 4ACH50 and proposed no changes to the prescriptive list. The ME+D
comment initially supported 4ACH50 at the hearing and requested an improved
prescriptive list.
In subsequent written comments, ME+D amended its comment to set
allowable air changes to 5ACH50, rather than 4ACH50, stating that the allowable air
change threshold would be a significant improvement if testing was available and
that the prescriptive option will be used in almost all cases, but relies on vigilant
building inspectors and builders.
A commenter recommended mandatory 3ACH50 air exchange. Another
commenter urged the department to set maximum acceptable blower door test
results at 5ACH50, rather than the proposed 4ACH50, to increase the number of
builders who will select this option from the code, rather than the visual inspection
option in 402.4.2.2. A little more than half of the comments advocated for an energy
efficiency or performance test (such as a blower door test) to be added as a code
requirement for newly built homes.
Response: The department derived the original proposal of 4ACH based on strong
stakeholder input. Until a good supply of blower door test units become available to
owners and builders, and their use is considered regular, the tighter specification of
4ACH is valid. once these blower door units become more available and used, the
department will be very interested in evaluating the suggested ACH parameter
based on stakeholder input.
f. Ventilation: The 2009 IECC does not require mechanical ventilation. The
department proposed the same. However, the M E+D proposal requested
mechanical ventilation per ASHREA 50.2.
Response: The department evaluated the use of the additional standard (ASHREA)
for ventilation. Neither the 2009 IECC nor the code development committees
embraced the ASHREA 60.2 as a referenced standard. The department has
amended, after stakeholder request, the 2009 edition of the International Mechanical
Montana Administrative Register 0-3/25/10
--753--
code to require all single family houses to have a minimum benchmark for
ventilation through mechanical means and controlled by tuner or h umidistat.
COMMENT 3: A commenter asked that the department adopt residential energy
codes to exceed I ECc standards by at least 20 percent.
RESPONSE 3: The department's role is to balance the increases in code
requirements with that of welfare and economic considerations. The U.S.
Department of Energy estimates that the 2009 l ECG increases energy efficiency and
conservation 15 to 18 percent, over that of the 2006 edition. The department,
through this adoption proposal process, has also increased other energy code
requirements above those mandated in the 2009 IECC; thereby adding to the
increases in energy efficiency and conservation above 15 t❑ 18 percent.
COMMENT 4: A small group of commenters urged to adopt the rules as proposed,
but suggested that the Building codes council explore or encourage possible
solutions to the problem of lack of enforcement.
RESPONSE 4: The energy code is applicable to almost all buildings per statute.
Enforcement of the energy code is limited to inspection by local jurisdictions certified
by the department and a "self -certification" process detailed in statute. changes to
the current enforcement scenario will require direct intervention by the legislature.
COMMENT 5: A small group of commenters stated that there should be no building
code requirement at all, stating "a person should be allowed to build a house out of
plywood and heat it with solar electricity," and "building codes are supposed to be for
safety and integrity, not efficiency or sustainability."
RESPONSE 5: The department will maintain building code requirements that
incorporate energy efficiency standards under the rationale provided to Response 1.
4. The department has amended ARM 24.301.151 exactly as proposed.

(2) The purpose of the International Energy Conservation Code is to provide
minimum requirements for the design of new buildings and structures and additions to
existing buildings, regulating their exterior envelopes and selection of their heating,
ventilating, air conditioning, service water heating, electrical distribution and illuminating
systems, and equipment for effective use of energy.
(a) The department encourages owners, design professionals, and builders to
voluntarily implement greater levels of energy efficiency in building design and
construction than those required by the International Energy Conservation Code.
Information regarding voluntary building standards for greater levels of energy efficiency
can be obtained from the department by contacting the department at the address listed
in (3), by telephone at406--841-2053, or at the department's web site,
http://mt.gov/dli/bsd/bc/bs.
