Subject: Information Item: LJpdate on the implementation of Climate Action Plan regarding
proposed changes to Commercial and Residential Green Building Codes
PtiRPOSE:
The implementation of the city's Climate Action Plan (CAP) involves activities across many city
departments and operations and includes various strategies to reduce greenhouse gas (GIIG)
emissions. A status report on the further development of regulatory options involving the city's
building codes is being provided at this time. Information on other CAP related implementation
efforts is planned for distribution in a July 31, 2008 Weekly Information Packet item. 1'he status
of CAP programs and potential CAP tax rates, including more information on the results and
program selection rationale will be presented in the July 31 W]P. Staff from the Transportation
Division of the Public Works Department will t-eturn to council and appropriate boards for
consideration of amendments to the Transportation Master Plan ('I'MP) to reflect the
modifications suggested by the FasTracks Local Optimization (PLO) process later this year.
EXk;CUTIVI+; StJMMARY:
At the Jan. 25, 2008 City Council retreat, council members identified goals including enhancing
the energy performance of new commercial construction in the short term and developing a
comprehensive commercial code by year end.
A city council study session on the Climate Action Plan (CAP), transportation and renewable
energy strategies to reduce greenhouse gas (GHG) emissions was held on April 8, 2008. Council
generally supported the development and implementation of a commercial green building
program, and acknowledged that a commercial code should consider future International Energy
Conservation Code (IECC) updates and that work should be carefully coordinated with local
developers, building professionals and staff. Council also expressed a desire to include
requirements for remodels and additions in the Residential Cireen Points program.
In response to council feedback, staff has developed a plan for the proposed adoption of
Commercial and Residential Green Building Codes in 2008. The plan addresses the goal of
1
improving commercial energy efficiency by 30 percent and also provides for other code
improvements meant to align building code regulations with the goals of the Climate Action Plan
(CAP). Proposed code changes are scheduled for Planning Board review on Oct. 2, 2008 and
City Council consideration on Oct. 21, 2008. In order to align code adoptions with CAP
priorities, the proposed plan outlines a path to achieve eventual carbon neutrality in buildings,
pursuant to the 2030 Challenge (developed by Ed Mazria) to address energy consumption.
COMMUNITY SUSTAINABILI'I'Y ASSESSMENTS AND IMPACTS:
Economic: The adoption and consistent application of building codes and standards support all
segments of the community and a sustainable economy. Proposed code changes should be
evaluated to demonstrate how the economic impact and investment is offset by increasing energy
efficiency and corresponding reductions in ongoing operational costs.
F.nvironmenta[: Building codes play an important role in reducing energy use and carbon
emissions in the city's new and existing building stock. Reducing energy use in existing
buildings, especially rental housing and leased commercial space, may not be achieved
sufficiently through voluntary measures.
Social: Building codes address the social impacts of the Boulder community by supporting the
management of potential impacts to life and property. Additionally, energy efficiency
improvements benefit the community by reducing carbon emissions. Homeowners benefit with
lower, more predictable utility bills as energy prices continue to increase. Requirements for
existing buildings could be expected to benefit tenants.
FISCAI. IiYIPACT:
Costs for the implementation of these code changes, including training for customers and staff,
are included within the city's operating budget. Periodic code update and maintenance is part of
the normal work plan involving the use of staff resources.
RACK(GROUND:
Boulder periodically updates its construction codes. This effort is done in a coordinated and
integrated manner in order to maintain a practical balance between safety and costs to protect life
and property while advancing green building objectives pertaining to sustainable development.
The 2006 International knergy Conservation Code (IECC), adopted by the city on Oct. 30, 2007
(and in effect since Jan. 2. 2008), applies to both commercial and residential construction.
updates to the residential Green Points were adopted on Nov. 13, 2007 (and became effective
Fcb. I, 2008). The "Green Building" components of the program involve requirements that
establish:
• Energy efficiency baselines above the 2006 IECC,
• Consm~ction waste recycling on new construction,
• An energy audit and efficient lighting for an existing house with a remodel or addition,
• Deconstruction for remodels removing 50 percent or more of the exterior walls.
The Green Points component remains similar to the prior program requiring a specific amount
of points (determined by project type and size) which are obtained by choosing green point
2
options outlined in a menu of green practices, technologies and products in the Green Points
Guidelines booklet.
Since a significant portion of development activity in Boulder involves residential remodels and
additions, as part of the 2007 Green Points adoption process, council requested that staff evaluate
an amendment to Green Points to respond to the concern that some threshold of "additions" and
"remodels" should be evaluated as "new construction" for the purpose of applying energy
efficiency requirements. In this evaluation, staff was directed to review the Boulder County
threshold for new construction. Council requested that the ordinance be scheduled for the Nov.
13, 2007 meeting as a public hearing (in addition to first reading). Ordinance 7570 was
considered at first reading, but concerns about potential unintended consequences, such as
encouraging more scrape-offs, resulted in direction to staff to evaluate alternative approaches.
At the January 25, 2008 City Council retreat, council members identified goals including
enhancing the energy performance of new commercial construction in the short term and
developing a comprehensive commercial code by year end.
A city council study session on the Climate Action Plan (CAP), and transportation and
renewable energy strategies to reduce greenhouse gas (GHG) emissions was held on April 8,
2008. Council generally supported the development and implementation of a commercial green
building program and acknowledged the importance of implementing an above-code energy
requirement to avoid any missed opportunities. Council acknowledged that any commercial code
should consider future International Energy Conservation Code (IECC) updates and that work
should be carefully coordinated with local developers, building professionals and staff. Council
also urged caution and sensitivity in developing a commercial green building code that might
impact the business community or economic vitality. Council also expressed a desire to include
requirements for remodels and additions in the Residential Green Points program. The
summary of the April 8, 2008 study session was accepted by the City Council on May 2U, 2008.
ANALYSIS:
Tn response to council feedback., staff has developed a plan for the proposed adoption of
Commercial and Residential Green Building Codes in 2008. 'hhe plan addresses the immediate
goal of improving commercial energy efficiency by 30 percent and also projects other code
improvements meant to align building code regulations wish the goals of the Climate Action Plan
(CAP).
The current city goal, Kyoto Protocol, is to reduce carbon emissions seven percent below 1990
levels by 2012. It is staff's intent to open the discussion with City Council nn goals beyond
2012, which will assist staff in understanding what the next phase is in relation to reducing
energy use and carbon emissions. More aggressive greenhouse gas goals are being developed by
industry and stakeholder groups across the country and throughout the world identifying the next
step in creating a sustainable energy future. In order to align code adoptions with CAP priorities,
the proposed plan outlines a path to achieve eventual carbon neutrality in buildings, pursuant to
the 2030 Challenge (developed by Ed Mazria) to address energy consumption.
3
Aligning building regulations with the overall CAP involve complex and controversial issues. In
order to facilitate working through these issues, staff has considered green building proposals for
the following six categories which are also shown in Attachment C;:
1. New International Residential Code (IRC) Construction (Duplexes, Townhouses and
Single Family Dwellings)
2. IRC Remodels and Additions
3. Existing IRC Buildings (No Permit Activity)
4. New International Building Code (IBC) Construction (Commercial, Industrial and
Multiple-residences)
5. IBC Remodels and Additions
6. Existing IBC Commercial, Industrial and Multiple-residences (No Permit Activity)
Proposed 2008 Green Building Changes:
As described previously and depicted in Attachment C, code changes were implemented earlier
this year for residential construction with the adoption of the updated Green Building and Green
Points (GBGP) and amulti-tiered residential Home Energy Rating System (HERS) "above-
code" program. Depending on the square footage of a residential structure, the percentage above
the currently adopted 2006 IECC varies from a minimum of 30 to a maximum of 7,5 percent.
While the GBGP is a residential program, the residential portions of mixed-use developments
have also been required to attain energy efficiency compliance 30 percent better than the baseline
2006 IECC.
T'he 2006 IECC was also adopted in early 2008 for commercial and industrial projects
constructed within the city of Boulder. The 2006 IECC simplified the methods for designing
projects but did not substantively require enhancements to the overall energy efficiency of
commercial and industrial buildings from the previous code.
Staff is currently developing the analysis required to amend the 2006 IF,CC to meet the 30
percent commercial energy improvement. If adopted, the commercial components of the typical
mixed-use development will attain a level of energy efficiency compliance 30 percent above the
IECC. Attaining this level of efficiency will eliminate the current discrepancy that exists
between the energy efficiency required for commercial and residential occupancies in mixed-use
buildings.
As noted, the City Council previously directed staff to amend the GBGP ordinance 7565) by
establishing a threshold for when a remodel and addition is extensive enough to warrant being
regulated as new construction. The threshold was to be developed without increasing incentives
to totally demolish existing housing to accommodate rebuilding larger structures. A first
reading of the resulting Ordinance 7570 was conducted on Nov. 13, 2007, but no further action
was taken due to concerns about potential unintended consequences, such as encouraging more
scrape-offs. Staff' has examined alternative approaches and a second reading of the ordinance is
currently scheduled for council consideration at the Oct. 21, 2008 council meeting with the intent
of the ordinance being effective on Jan.S, 2009.
4
In response to council's direction to develop an above-code program for commercial
construction energy efficiency, staff has been researching the requirements of other cities that are
also actively developing sustainable building regulations such as Portland, Oregon; Chicago,
Illinois and Albuquerque, New Mexico. Standards such as LEER, Green Globes, and the United
Kingdom program BREEAM were also considered in concert with the Boulder County
Consortium of Cities development of a green building code, which is meant to facilitate the
consistent adoption of green building requirements far local jurisdictions.
An important consideration for developing an above-code program is establishing a consistent
baseline reference. Most of the above-code energy efficiency standards that have been
developed reference the American Society of Heating, Refrigerating and Air-Conditioning
Engineers (ASHRAE) standard 90.1-2004. Z`his is also the design standard referenced by the
2006 IECC. When a percentage above code is referenced through the rest of the document the
baseline considered is ASHRAE 90.1-2004.
The research done by staff suggests that compliance with the commercial 30 percent above-code
energy efficiency level can be attained through the criteria detailed in Chapter 5 of the 2006
IECC which includes:
1. ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except for Low-Rise
Residential Buildinas.
2. United States Department of Energy, building energy requirements calculated through
the ComCheck computerized design program, most current version, www.doe.~.
3. Staff would also accept alternate design methods that could detail 30 percent better
than code such as ASHRAE standard 189.1 and the Advanced Energy Design Guides.
Staff also recommends that commercial buildings over 21),000 syuare feet be required to include
modeling as suggested by a stakeholder from the local design professional community. Energy
modeling is also a feature of the above-code program developed by Albuquerque, New Mexico
for buildings that are over 20,000 square feet.
An ordinance representing council's direction will be drafted and presented to the Planning
Board and City Council. The proposed code adoption schedule is outlined in Attachment A and
the implementation date of Jan. 5, 2009 is planned to allow time for staff to provide public
education programs prior to adoption. This code adoption time frame also allows building
designers to "gear-up" wish commercial and industrial projects currently in the design phase.
An alternate proposal was presented to the council from local stakeholders that suggested
adopting ASIIRAE 189.1 (207 pages long) as part of the city of Boulder commercial green
building code. This standard has just come out of a public comment period and wilt not be ready
far adoption until early 2009. Stal'i~will include the review oi'this document in the 2009 IECC
review and adoption process. When this design criteria is completed by ASHRAE, it could be
used as an alternate design acceptable through the adoption of the 2006 IECC 30 percent above-
code program.
i
Attachment B also summarizes other code change proposals planned for 2008 that would be
combined with this effort in order to facilitate training and code change implementation foT•
customers and staff.
Proposed 2009/2010 Green Building Changes:
Within the first half of 2009, the International Code Council (ICC) will publish the 2009
International Energy Conservation Code. Staff will review the 2009 IECC, the currently adopted
codes and other nationally developed green building standards and provide recommendations fo
council for a comprehensive Green Building Code that meets the needs of the city of Boulder.
Recommendations will be provided to council relating to items #l, #2, #4 and #5 outlined in
Attachment C. Work associated with upgrading to a modified 2009 IECC will begin in the
second or third quarter of 2009 (depending on when the 2009 IECC is published) with an
implementation date of January 2010. It is also planned that staff will include the proposed
2010/2012 requirements into the 2009 adoption process.
For Green Building proposals related to residential construction, staff will review the current city
GBGP program, the 2009 .IECC and other green building information before making
recommendations to the council. Preliminarily, staff is considering that the 30 to 75 percent
above code HERS requirements would be retained when the 2009 codes are adopted. The recent
development of green building codes such as the National Association of Home Builders
(NAHB)/ICC Green Building Code means that it is now possible to adopt a nationally developed
green building code. Staff will develop recommendations for amendment and adoption of the
2009 IECC, and the NAHB/ICC Model Green Home Building Guidelines to accomplish the
energy efficiency and sustainabitity goals of the GBGP program without the complications of
developing and maintaining a city produced document and point system.
In regard to existing residential constriction, currently an energy audit is required for remodets
and additions with no requirement to upgrade the existing structure based on the audit. One
recommendation is to require implementation of the energy audit findings. A feasibility
threshold will be established to limit the cost of the energy audit improvements to a percentage
of the project budget.
For Green Building proposals related to item #4 and #5 (of Attachment C) New IBC
Commercial/Residential and Commercial/Residential Remodel/Additions, staff will review the
2009 IECC, the Commercial Energy Star program, ASHRAE 189.1, Advanced Energy Design
Guides and other information to formulate recommendations to the council for their
consideration to modify and adopt a new above code program. The proposed program could
include performance and prescriptive paths of design and renewable and sustainable components
as part of the recommendations. The IBC Multi-Residential component will be transferred from
the current Green Building and Green Points program to the green building program being
developed for commercial construction. 'T'his would allow the green building requirements for
residential units in large commercial buildings to be better suited to the needs of a commercial
G
site. The commercial code requirements will continue to be at least 30 percent above the 2009
IECC.
The emphasis for 2009 and 2010 would be to work through the code adoption process with
amendments that support the energy efficiency goals established in 2008. While energy
efficiency improvements are not changed from 2008, phasing of higher energy efficiency
requirements will be established for 2010 and 2011.
Proposed 2010/2011 Green Building Changes:
The Green Building proposal for item #1 (Attachment C) on the New IRC Residential Buildings,
is to increase the energy efficiency represented by the HERS rating by at least 10 percent on
BRC l U-7.5-3 Table 1.
The Green Building proposal for item #2, Residential Remodels/Additions, is to include the
entire structure in the HERS rating.
"The Green Building proposal for item #3, Existing Residential Building (with no permit
activity), is to require an energy audit and envelope remediation when an existing home is sold
or the rental license is renewed.
The Green Building proposal for item #4 and #5, New 1BC Commercial/Residential and IBC
Commercial/Residential Remodels/Additions, will include a sustainability program that will
include demolition and construction waste recycling programs.
The Green Building proposal for item #6, Existing CommerciaUResidential (with no permit
activity), would be to potentially require an energy audit and envelope remediation when all or
some of the following occur: building sale; rental license renewal; IBC change of use; and/or
zoning site plan review. It should be noted that the staff analysis for this work is not completed
and that it is premature to forecast the staff recommendation. The Commercial Energy Star
Program or other program could be reviewed and compliance measures proposed to council.
These proposals will be further developed and presented to the council during 2009 as part of the
2009 IECC review and adoption process. An implementation date of January 2011 (one year
after the January 2010 adoption date of the 2009 IECC and related city of Boulder amendments)
is proposed.
While not all of the answers on how to achieve the CAP goals ofcarbon-neutral constn~ction are
currently known, one consideration for building codes is to increase the energy efficiency of the
buildings by 50 to 60 percent and then explore implementation of renewable energy to attain
carbon neutral buildings. The work in this time frame increases energy efficiency requirements
as a start to the process of how to make new and existing structures contribute to attaining carbon
neutrality.
Proposed 2011/2012 Green Building Changes:
7
The Green Building Proposal for residential items #1, #2, #3 and #6 will include a
recommendation fora 10 percent improvement in the energy efficiency requirements. Items #4
and lf5 are proposed to improve energy efficiency 50 percent or more above the baseline. ICC
will publish the 2012 IF,CC during the first half of 2012. P&DS will review the document during
the third quarter of 2012 to determine what course of action should be recommended to the
council. for amendments and adoption in January 20 } 3.
Most of the work during this time period is to develop codes that result in energy efficiency
improvements in the 50 to 60 percent range.
Proposed 2015/2016/2030 Greeu Building Changes:
Staff will be working toward a January 2016 adoption of the 2015 IECC and necessary code
updates and amendments in a continuing effort to align development requirements with meeting
carbon neutral energy building goals. In addition, developing requirements for on- and off=site
renewable energy generation would be incorporated in the 2016-code adoptions to attain the
2030 goal of carbon neutrality for buildings.
Program Support for Commercial and Residential Code Adoption Processes:
The Office of Environmental Affairs' (OEA) green building and Climate Action Plan work
develops and implements programs that will continue to support evolving codes to a higher level
of energy efficiency and sustainability.
OEA has a successful history of developing incentives, subsidies and programs to support the
Green Points program. In the last two years, program support has grown for Green Points
because of the added CAP initiatives and funding. CllITCnt programs and incentives supporting
energy efficient upgrades and residential green building codes consist of, but are not limited to,
subsidies for construction waste material recycling infrastn.icture, free deconstruction services
for building permit applicants that trigger deconstnuction mandates, subsidized energy audits,
contractor and building professional technical training, workshops and conferences, insulation
and high efficiency lighting rebates. As the remodel and addition component of the Green
Building and Green Points Ordinance returns to council later this year, staff will be presenting
options to increase requirements for these projects. Also during this timcframe, OEA is engaging
in research, followed by public process to explore opportunities for energy of#iciency
requirements in existing housing.
OEA also plays a significant role interdepartmentally providing technical support to drive the
research, evaluation and public process far emerging energy efficiency issues, technologies and
practices in the market place. As the CAP work evolves from initial voluntary efforts to more
aggressive initiatives, OEA, Planning and Public Works staff will work even more closely to
integrate code adoption and reduction of energy and greenhouse gas emissions. 1'he city will
also continue to work with other community partners such as the Governor's Energy Office,
Boulder County, the Consortium of Cities and Xcel Energy on program development. These
partnerships will enhance the residential and commercial sectors' ability to employ design and
8
construction energy efficiency measures, practices and renewable energy technologies. OEA wiil
continue to focus on education and support in implementing Xcel's incentives and rebates for
both sectors. With Boulder becoming the first SmartGrid community in the country, there will
be incredible opportunities to work with residents and businesses to reduce their energy
consumption.
NEXT STEPS:
The Aug. 12, 2008 City Council Study Session on Citywide Work Program & Priorities provides
council with the opportunity to offer feedback on work plans, including this proposed schedule
for the adoption of new building codes. In the interim, please contact Kirk Moors, Neil Paulsen
or Maureen Rait, if additional information is needed.

ATTACHMENT B
Minor Revisions to 2006 International Building Code
Adoption of the 2008 National Electrical Code
It is proposed that the city of Boulder adopt minor changes to the previously adopted
International Code Council (ICC), 2006 International Building Code (IBC) and adopt by
reference the 2008 National Electrical Code (NEC) with modifieativns.
The periodic adoption of new construction codes is a standard practice of the city of Boulder and
other local agencies. The cvde changes and code proposed for adoption by reference is available
for public use at the Planning & Development Services Center, located on the 3rd flovr of the
Park Central Building at 1739 Broadway and at the Office of the City Clerk/Central Records.
Local amendments, while being kept to a minimum, are proposed to address local issues related
to the code. A summary of key Local amendments and changes from the codes is provided below.
2006 International Buildin Cvde IBC) Amendments
IBC Section 105.32, "`l'ime Limitation of Application", the current modified code language is
repealed and replaced with the original ICC text which allows the building official more
flexibility in allowing extensions of plan reviews when necessary.
IBC Section 105.5 "Expiration", the current modified code language is repealed and replaced
with the original text with the addition of the following code language at the end of the
paragraph: "Every permit issued by the building official under the provisions of this code shall
expire by limitation and become null and void if the building or work authorized by such permit
is not completed and approved for occupancy within three years from the date the permit was
issued. T7re permit fee for renewals may be prorated based on the amount of work completed and
approved under the previous permit."
2008 National Electrical Code
The 2008 edition of the National Electrical Code (NEC) of the National Fire protection
Association is adopted by reference as the city of Boulder Electrical Code or electrical code and
has the same force and effect as though fully set forth in this chapter, except as specifically
amended by the provisions of this chapter.
The current modified code language in items (I), (m) and (p) is repealed and replaced with the
2008 NE;C code text. All three references were allowances for the use of NM cable (romex) in
residential occupancies that need to be modified to meet minimum state of Colorado Electrical
Board requirements.
