International Green Construction Code
The Green Codes Landscape in a World of
Standards & Rating Systems – November 15, 2011
What is the
IGCC?

An Adoptable, Useable and
Enforceable building code

Intended to reduce the
negative impacts of the built
environment on the natural
environment

Addresses

Conservation of:

Natural resources

Materials

Energy

Water

Air & indoor
environmental quality
The development of a code occurs
when there is a clear need
indicated from regulators and
others in the building safety
industry.
Why is the ICC
promoting its
Green
Construction
Code when
other options
already exist?
In the case of the IGCC, there has
been an increasing call for an
actual code that is clear and
enforceable.
We have heard this not only from
our members in local and state
government, but from
stakeholders across the spectrum.
For example, architects want a
code book that will guide their
design activities just like the other
I-Codes.

The IGCC is not a rating system,
nor is it intended to replace them.

The IGCC is code which is
intended to be adopted on
mandatory basis.

Unlike most rating systems, the
IGCC primarily consists of
minimum mandatory
requirements, just as other ICodes.

Because it is intended to apply to
both private sector and
government owned buildings– it
raises the bar on sustainability for
all commercial buildings –
positioning the IGCC to achieve
massive environmental benefits
not possible with voluntary rating
systems.
IGCC
Context
The ICC Board created a Sustainable
Building Technology Committee
(SBTC) composed of 28 individuals
from multiple sectors, to draft Public
Version 1.0.
How does the
development
process work?
The SBTC conducted open meetings
around the U.S. between July 2009 and
January 2010, creating IGCC Public
Version 1.0 as a tool for jurisdictions
wishing to develop a code based on
the ICC process.
In August of 2010, an IGCC public
comment committee considered over
1,500 comments related to Public
Version 1.0 at public hearings in
Chicago, Illinois. The committee’s
decisions were incorporated in Public
Version 2.0.
IGCC Development Schedule
IGCC PV 1.0 posted for public comment March 15 to May 14, 2010.
Public comments posted July 2, 2010.
Public hearings to review public comments to PV 1.0 held August 14 to
22, 2010.
PV 2.0 posted for public comments November 3, 2010, with comments
due by January 3, 2011.
IGCC Code Development Hearing May 16 through 22, 2011, Dallas,
Texas.
A Final Action Hearing November 3 through 6, 2011, Phoenix, Arizona,
in conjunction with the 2011 ICC Annual Conference
The first edition of the IGCC is scheduled to be published in early 2012.
How does the
development
process work?
Once the 2012 Code is issued, it
will be revisited every three
years along with the other ICodes, through the two-hearing
process used to update all of the
I-Codes.
Scope
Commercial & HighPerformance Buildings

Will apply to traditional commercial
and high-performance buildings.

Consistent and coordinated with the
ICC family of Codes & Standards.

Applicable to the construction of
buildings, structures, and systems,
including alterations and additions.

Will provide a new regulatory
framework with customization
features to allow jurisdictional
options beyond IGCC baseline.

Designed with leading recognized
rating systems and standards in
mind.

Will provide criteria to measure
compliance & drive green building
into everyday practice.
Integrated with I-Codes
Option to Customize
ASHRAE/USGBC/IES
Standard 189.1 included
as Jurisdictional
Compliance Option
Tied to Building
Performance
Concepts

Will use the “model” code approach
that provides communities the ability
to modify.

Minimum & advanced levels of
performance (green & highperformance buildings).

Work as an overlay to the ICC Family
of Codes.

Written in mandatory language that
provides a new regulatory
framework.
Concepts


ANSI/ASHRAE/USGBC/IES Standard 189.1 also is offered as
a jurisdictional compliance option.

The Standard is included with the IGCC.

Adoption of the Standard occurs via the local jurisdiction
adoption process.
Providing the IGCC, including the189.1 option, allows the
widest set of options to a jurisdiction, all under the umbrella
of the IGCC.

Timing of the IGCC Initiative
The IGCC initiative builds upon the good work of many
organizations and advocates concerned with a more
sustainable built environment.
 It
is not designed to compete against, or minimize,
the systems and standards that are already in place.
 We
anticipate our code development process will
utilize existing work as a resource.
The timing of this activity is appropriate in the evolution of
the sustainability efforts in the U.S. and around the world.
 Now
that various approaches have been tested and
implemented, we have a clearer picture as to what is
required in a code.
 We
also better understand how a code can be useful
and why a code is necessary.
The IGCC Cooperating Sponsors
include:
American Institute of Architects
(AIA)
ASTM International (ASTM)
Who is
supporting
the ICC in
this effort?
American Society of Heating,
Refrigeration and Air
Conditioning Engineers (ASHRAE )
U.S. Green Building Council
(USGBC)
Illuminating Engineering Society
(IES)
What is the
difference
between the
IGCC and other
systems and
standards such
as LEED, Green
Globes, etc. ?
The IGCC creates a regulatory
framework for new and
existing commercial and highperformance
buildings. Rating systems are
not written in the form of
enforceable codes.
IGCC will provide baseline
benchmarks for sustainable
building practices to “raise
the floor” of green building
while voluntary ratings
systems like LEED will
continue to push the envelope
for developers who
commission projects with
sustainability characteristics
above and beyond the
baseline, thereby “raising the
ceiling.”
How will the
IGCC differ
from a national
or federal
mandate?
The IGCC will be a “model”
code, requiring adoption by a
governing jurisdiction before
it becomes law. In this way,
the model language can, if
necessary, be adapted to
address local conditions and
allows for publicly elected
legislative bodies to have the
final voice in adoption. Many
of the I-Codes are adopted
without amendment at the
state or local level; amended
versions often take into
account local weather and
hazard conditions, regional
approaches to building
design and construction, and
other factors.
How will the IGCC
differ from other
International Codes
such as the
International
Building Code
(IBC)?
One of the values of the
IGCC is that it will be
designed to coordinate and
integrate with existing ICodes. The IGCC includes
various levels for
jurisdictions to apply
unique “green”
requirements to
commercial buildings. The
IGCC will not replace the
IBC but rather can be
adopted and used in
conjunction with the
adopted IBC, as well as all
the other I-Codes.

Unlike classic code adoption,
where the goal is to minimize
amendments to the model
language and promote
wholesale adoption, the IGCC
is purposely designed as an
“adaptable tool” that may
become law in its entirety.

Simply put, a
green building
code and a
beyond-code
green building
rating system
provide the
best-case
scenario of
push-and-pull
market-driving
tools.
Adopting
and Implementing
IGCC

A number of jurisdictions have
legislation in place or in
preliminary planning that adopt
and/or reference the IGCC as
their guideline for green
construction.

States and local jurisdictions
from coast to coast have
discussions underway to adopt
the IGCC.
