International Green Construction Code Dave Walls, International Code Council

2. Objectives This presentation is intended to communicate:
How the IgCC fits in the context of green building standards and rating systems
How and why the IgCC was developed
Unique aspects of the IgCC
Technical highlights of the IgCC
Where the IgCC has been adopted
Update on the next code cycle

3. What is the IgCC? An Adoptable, Useable and Enforceable 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

4. Intent and Scope
Consistent and coordinated with the ICC family of Codes & Standards
Intended to be enforced primarily by building officials/local jurisdictions
Intended to drive green building into everyday practice
Applicable to the construction of
All buildings, both old and new, except:
IRC Buildings (1-and 2-family dwellings)
R-3 Occupancies
R-2 and R-4 Occupancies 4 stories or less in height.
Exceptions above are regulated by ICC 700 where the jurisdiction indicates so in Table

5. Developed By:
IgCC developed by ICC in association with cooperating sponsors:
ASTM and
American Institute of Architects (AIA)
References ASHRAE as an alternative compliance path, as developed by:
ASHRAE and partners
USGBC and
Illuminating Engineers (IES) 5

6. IgCC Context
The IgCC is not a rating system, nor is it intended to replace them.
The IgCC is a code which is intended to be adopted on a mandatory basis.
The IgCC consists of minimum mandatory requirements, similar to the other I-Codes.
The IgCC contains a new regulatory framework that facilitates both jurisdictional customization and flexibility for owners and designers.

7. Chapter 3: Jurisdictional Requirements and Life Cycle Assessment
A new regulatory framework
Allows jurisdictions to customize the code to address 20 additional environmental criteria
These criteria may not be appropriate for all jurisdictions.
May be beneficial in others.
Allow the jurisdiction to set higher minimum levels of performance.
Whole Building Life Cycle Assessment
Not a mandatory requirement.
An alternative to the material selection requirements of Section 505. 7

8. Chapter 4: Site Development and Land Use
Preservation of natural resources (Tied to Table )
Allows jurisdictions to prohibit construction in floodplains and limit development of certain sites and site features
Natural resources inventory required
Stormwater management
Landscape irrigation
Management of vegetation, soils and erosion control
Building site waste management
Transportation impact
Heat island mitigation
Site Lighting (Tied to Table )
402 Preservation of Natural Resources
Prohibits construction in floodplains.
Generally prohibits building within 50 feet (1524 mm) of bodies of water and wetlands (with exceptions)
Generally prohibits construction on park land (Section )
Requires natural resources inventory (Section )
Additional provisions for stormwater, erosion control, landscape irrigation, debris and soil recycling.
403 Transportation Impact
Encourages alternative transportation (bicycling, pedestrian, alt vehicles, public transit)
404 Heat Island Mitigation
Projects located in Climate Zones 1 through 6 must implement heat island mitigation practices for at least 50 percent of site hardscape.
Projects located in Climate Zones 1 through 3 must implement heat island mitigation practices for at least 75 percent of roof surfaces.
405 Site Lighting
Minimize light pollution

9. Chapter 5: Material Resource Conservation and Efficiency
Construction material and waste management plan
50% construction waste diversion min.
Jurisdictions can select higher values in Table
Requires recycling areas for use by building occupants
55% of materials must be:
Recycled,
Recyclable,
Bio-based, or
Indigenous.
(Materials are permitted to have multiple attributes.)
Mercury limits for fluorescent lamps
Moisture control
Construction Material and Waste Management Plan
At least 50 percent of construction phase waste materials must be diverted from landfills.

10. Chapter 6: Energy Conservation, Efficiency & CO2e Emission Reduction
The energy requirements are applicable to new buildings and additions to existing buildings.
Contains detailed energy requirements.
Energy requirements for alterations to existing buildings are found in Ch 10.
The IgCC provides the following energy compliance paths:
Prescriptive-based
Performance-based zEPI (Zero Energy Performance Index)
Outcome based performance [or Annual Net Energy Performance (ANEP) based] compliance:
Available for buildings of all sizes
Must have an ANEP no greater than that required for the occupancy or that determined by the jurisdiction
Peak energy demand must comply with IECC
Requires commissioning reports and annual operation reports
Must comply with IGCC Sections 604, 605 & 612
Requires a significant amount of information to be determined by the jurisdiction and entered in Tables 603.2(1), 603.2(2) and 603.2(3).
IGCC’s Energy Use Intensity (EUI) compliance path:
Is available for buildings of all sizes
Requires EUI that is in the top 10 percent of existing buildings eligible to a receive a score in EPA’s Target Finder program or
For buildings not eligible for a score in Target Finder, must be designed to deliver an EUI that is at least 50 percent lower than the average EUI for similar buildings in DOE’s SBECS
Determine EUI in accordance with the following equation:
EUI = TAE/SF (where TAE = Total annual energy projected to be consumed on site, including renewable energy; and SF = building gross square footage) (Section ) 10

The Building Air Quality guide, developed by the EPA and the National Institute for Occupational Safety and Health, provides practical suggestions on preventing, identifying, and resolving indoor air quality (IAQ) problems in public and commercial buildings. This guidance provides information on factors affecting indoor air quality; describes how to develop an IAQ profile of building conditions and create an IAQ management plan; describes investigative strategies to identify causes of IAQ problems; and provides criteria for assessing alternative mitigation strategies, determining whether a problem has been resolved, and deciding whether to consult outside technical specialists.
System components requiring unobstructed access for cleaning and repair include, ducts, air handler units, fans, coils and condensate pans.
Although not stated explicitly, there are indirect references to the Friability of materials in Section Friability meaning the ability of a solid substance to be reduced to smaller pieces with little effort.
Often, substances designated as being hazardous, such as asbestos or crystalline silica are referred to as being friable if they are present in such a state that it is possible for small particles to become dislodged, thus enabling them to become respirable (able to enter human lungs), posing a health hazard. Polyurethane foams, can increase in friability with exposure to ultraviolet radiation (such as is present in sunlight).
Examples include but are not limited to: Clumps of dried clay, Chalk, Stone, Tablets, Crackers, Perlite, Mineral fibers, Polyurethane (foam), and Aerogel.

Unaltered components can remain as they are
Requirements primarily related to energy & water
Capped at10% of the total cost of alterations & other exceptions.
Additions are treated much like new construction.
Historic buildings exempted from many provisions
Jurisdictions can choose to offer the evaluation of existing buildings for IgCC compliance.
Chapter 11 covers similar info for building sites.
Alterations to existing buildings: energy used after the alteration must not exceed the energy used prior to alterations.
