IgCC
Overview of the IgCC
Code officials recognize the need for a modern, up-to-date code governing the impact of buildings and structures on the environment. The International Green Construction Code (IgCC) is designed to meet this need through model code regulations that contain clear and specific requirements with provisions that promote safe and sustainable construction in an integrated fashion with the ICC Family of Codes.
This comprehensive green code establishes minimum regulations for building systems and site considerations using prescriptive and performance-related provisions. It is intended to be an overlay code to be used with, and is fully compatible with, the Family of International Codes.
Benefits of the IgCC:
The International Green Construction Code provides a whole systems approach to the design, construction and operation of buildings.- The International Green Construction Code includes measures that result in better indoor environments, lower impact on natural resources, better neighborhood connections, and improved walkability.
- The International Green Construction Code is coordinated with other model codes such as IECC®, 90.1, and many other referenced standards.
- The International Green Construction Code is a public/private collaboration that provides a green model code to government jurisdictions. As a result, government does not have to take on the high cost of developing its own code and benefits from the code uniformity among adopting jurisdictions.
- USGBC is developing synergies between specific IgCC measures and LEED® credits, enabling a streamlined approach to leadership that is built on a consistent green code.
The International Green Construction Code provides a whole systems approach to the design, construction and operation of buildings.Why IgCC?
- Green building strategies reinforce societal health/life/safety benefits that building codes offer, providing resilience to natural disasters, climate change, resource consumption/management, and service interruptions due to unforeseen events.
- Industry-leading codes, standards, and the LEED® rating system have enabled the construction sector to introduce fundamental strategies to protect occupant comfort and health, save money, and preserve resources during the design, construction, and operation of buildings.
- The implementation of green building design, construction, and operational techniques has increased. Many homeowners, businesses, and building professionals have voluntarily sought to incorporate green building strategies into their projects, and a number of local and national systems have been developed to guide green building practices, including LEED®.
- Buildings account for over 12% of water use, 40% of CO2 emissions, 65% of all waste outputs, and more than 70% of electricity consumption. Our organizations believe green buildings offer solutions to many of these problems by conserving resources, regenerating sites, and providing economic and societal benefits.
- The benefits of green building design, construction, and operation should be enjoyed by residents, workers, and visitors of all cities.
On IgCC’s Strategic Development Relationships with Key Industry Leaders – ICC, ASHRAE, USGBC, AIA and IES:
- Our organizations are dedicated to continuously improving the built environment by providing safe, sustainable and equitable buildings for all.
- Green codes help fulfill the mission of our organizations: To provide for the health, life and safety of the built environment; to increase economic and resource efficiency of buildings; to reduce effects of climate change through more resilient buildings, communities, and cities; and to provide for the best buildings of today without compromising the needs of future generations.
- Our goal is to transform the market by leveraging the strengths of ICC and ASHRAE to develop the highest standard of green building codes that provide direct connections to the U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED®) rating system.
- The partnership between AIA, ASHRAE, ICC, IES and USGBC on the 2018 International Green Construction Code (IgCC®) represents the perfect formula for green building codes: The most trusted code development body; the most technically sophisticated HVAC&R standards development organization; the most influential green building rating system; and the design community’s top-tier professional organizations.
- Our partnership represents model code developers, regulatory adoption agencies, building officials, architects, engineers, the design community, construction practitioners, sustainability professionals, and industry associations.

The International Green Construction Code provisions provide many benefits, among which is the model code development process that offers an international forum for building professionals to discuss performance and prescriptive code requirements. This forum provides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the application of provisions.

Cost Impact for 2022 Group B Code Changes.
In support of the ICC Code Development Process, the Industry Advisory Committee (IAC) recommended the development of a Cost Impact Guide which provides information regarding the requirements concerning the cost impact statements that are required as part of every code change proposal. The IAC completed the guide which has been endorsed by the Board Committee on the Long Term Code Development Process and approved by the Code Council Board of Directors. This guide was developed with input from Industry Advisory Committee members, from code officials, and from ICC staff. The guide is intended to be a useful and informative resource that will help in understanding the purpose and objective of the cost impact requirements in the code submission process.

Magnesium Oxide Board Consensus Committee
(IS-MGOB)
IS-MGOB is focused on solutions for Magnesium Oxide Boards and their use in construction.
ICC 1125 Standard for Classification of Magnesium Oxide Boards and Construction
The first edition of ICC 1125 is being developed under the Code Council’s ANSI Accredited Consensus Procedures.
Abstract: The Code Council is developing this new standard to be referenced in the I-Codes. In response to feedback from industry, the Code Council identified that a North American product standard for building and construction uses of Magnesium Oxide (MgO) boards does not exist, and the product is viewed as unique to each manufacturer. MgO board usage in North American construction is growing, and an industry standard to establish minimally acceptable performance levels to ensure proper MgO board performance in buildings is needed.

2023 DOE HVAC Efficiency Requirements
What you need to know!
The U.S. Department of Energy (DOE) enacted new energy efficiency requirements for residential and commercial air conditioners and heat pumps that went into effect on January 1, 2023. These new regulations affect code compliance for mechanical equipment regardless of the state or local code edition that has been adopted because federal appliance standards preempt state and local construction codes.
"NEW" Residential Efficiency Requirements and Test Standards
The efficiency changes for residential products can be confusing.
"NEW" Commercial Efficiency Requirements
The efficiency changes for commercial products are fairly straightforward.

The IFGC is the most widely adopted fuel gas code across the United States. The IFGC is currently adopted in 41 states across the U.S. and is also adopted in the District of Columbia, Puerto Rico, and Guam. Approximately 280 million people, or 82% of the US population, live in areas that have adopted the IFGC.
The IFGC is also used in Pakistan and other countries around the world.
The IFGC is a vital part of a complete building safety system, providing an integral component necessary to provide an acceptable level of safety and to protect life and property from the potential dangers associated with the storage, distribution and usage of fuel
gases and the byproducts of combustion of such fuels.
The I-Codes, when adopted as a family of codes, correlating as they do, provide a consistent system of regulations that designers, builders, and regulators can rely on,
across city, county, or state lines.
It is for this reason that FEMA’s “Consensus-based Codes, Specifications and Standards for Public Assistance Policy” requires that as a condition of grant funding, the I-Codes be incorporated into the design and construction for repair and replacement of disaster-damaged facilities. FEMA requires construction not only meet the latest editions of the IBC, IPC, IMC, IECC, and IFC, but also the IFGC.
The adoption of building codes, including the fuel gas code, is not just about the codes. Technical support, in the form of expert advice, code opinions, and technical resources are some of the most sought-after services following adoption of a code.
The Code Council’s expert technical staff provides advice, code opinions, and resources to our more than 70,000 members as a complimentary benefit.
We have several resources, including commentaries and study companions, to support our members and industry professionals in achieving a better understanding of the code and implementing inspection programs.
Numerous training resources are available on the IFGC including face to face training and webinars which are led by qualified instructors and fuel gas industry leaders.
The Code Council also has a world class digital platform where codes, industry standards and resources can be accessed from one’s computer, tablet, or phone.
The IFGC is developed through a governmental consensus process
that involves many interest groups including public safety officials, contractors, manufacturers, standards development organizations, academia, consumers and many more;
cannot be influenced by vested financial interests;
and is conducted every three years.
The IMC is the most widely adopted mechanical code across the United States. The IMC is currently adopted in 47 states across the U.S. and is also adopted in the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands. Approximately 299 million people, or 88% of the US population, live in areas that have adopted the IMC.
The IMC is also used in Saudi Arabia, Pakistan, and other countries around the world.
Why is the IMC the most resilient mechanical code around?
The IMC is a vital part of a complete building safety system, providing an integral component necessary to stay current with the latest building technologies while providing an acceptable level of safety to protect life and property from the potential dangers associated with the installation and operation of mechanical systems.
The I-Codes, when adopted as a family of codes, correlating as they do, provide a consistent system of regulations that designers, builders, and regulators can rely on,
across city, county, or state lines.
It is for this reason that FEMA’s “Consensus-based Codes, Specifications and Standards for Public Assistance Policy” requires that as a condition of grant funding, the I-Codes be incorporated into the design and construction for repair and replacement of disaster-damaged facilities. FEMA requires construction not only meet the latest editions of the IBC, IPC, IFGC, IECC, and IFC, but also the IMC.

Preparing for A2L Refrigerants
In late 2021, the United States Environmental Protection Agency (EPA) issued a rule implementing legislation that mandates an 85-percent nationwide phasedown in hydrofluorocarbon (HFC) refrigerants by 2036.
The following series of videos, from ICC and our industry partners, address some of the different aspects of the resulting transition to A2L refrigerants that are important for building inspectors, code officials and contractors.

Upcoming Code Changes
The 2024 I-Code changes facilitate compliance with these requirements and support producers and refrigerant appliance manufacturers already transitioning to lower-GWP solutions such as A2Ls. Approved code changes in the 2024 International Building Code (IBC), 2024 International Residential Code (IRC), International Fire Code (IFC) and International Mechanical Code (IMC) allow commercial and residential use of A2L refrigerants to replace high global warming potential (GWP) HFC refrigerants (Click here to download changes to the 2024 I-Codes)
The Code Council, in collaboration with the Air-Conditioning, Heating and Refrigeration Institute (AHRI), Plumbing-Heating-Cooling Contractors Association (PHCC), Air Conditioning Contractors of America (ACCA), and Heating Air-Conditioning & Refrigeration Distributors International (HARDI) are prepared to partner with the construction industry to help navigate this positive change.
