As a movement and an industry, green building is evolving rapidly. Recognizing leadership in this field means periodically moving the goal posts, and rethinking the measures by which leadership is assessed. That’s the reason for LEED Version 4, the next exciting step in the continuous improvement of the LEED rating systems.

The development of LEED v4 has spanned more than three years, engaged hundreds of volunteers and thousands of stakeholders around the world. LEED v4 has the potential to drive the reduction of building carbon emissions and take a stronger stand on human health, more so than any previous version of LEED.

Registration Process


Upgrade to LEED v4 at no cost!

Projects registered for LEED Canada 2009 (or v1 for Commercial Interiors) can upgrade to LEED v4 at no cost – contact info@cagbc.org for details!



Registration for LEED v4 is straightforward.  To start, simply register the project through the CaGBC’s website as you would normally, selecting the LEED v4 rating system that applies to your project. For additional information on the many rating systems available, please see the LEED v4 Rating System Selection Guidance.

Organizations that are CaGBC member Specialists benefit from reduced registration fees. Rates remain unchanged for LEED v4.

Following registration, teams will be provided with an access number for creating their project profile in LEED Online, a platform that helps teams coordinate and expedite the documentation and certification process.

The CaGBC will provide LEED v4 project teams all the support they need. Our customer service team will be happy to answer any technical, administrative or other questions; they can be reached at info@cagbc.org or 1-866-941-1184.

In order to facilitate the transition to LEED v4, projects will be able to register for the LEED Canada 2009 (v1 for Commercial Interiors) rating systems until October 31, 2016. This will provide a period of time during which project teams will have the opportunity to choose which version to register under.

Technical Updates and New Market Sectors

Guided by a set of goals for what LEED projects should accomplish, LEED v4 includes a comprehensive technical update to the rating system requirements. While some aspects remain familiar, others incorporate important, fundamental revisions. Materials, for example, are evaluated more holistically using multiple attributes through approaches such as Life Cycle Assessment and Environmental Product Declarations. There is a greater emphasis on performance, as reflected in water and energy metering requirements, while integrative design, envelope commissioning, and acoustics are some of the new issues addressed within LEED v4.

Projects now use the LEED rating system on a wider variety of project types than ever before. From stadiums to convention centers, commercial offices to hospitals, each space type has unique needs and challenges when using LEED. LEED v4 addresses 21 different market sector adaptations, including new and existing data centers, new and existing warehouse and distribution centers, hospitality, existing schools, existing retail, and multifamily midrise. To view the rating systems, check-out our LEED v4 Resources.

LEED v4 in Canada

What does LEED v4 mean to Canadian project teams? Fundamentally, better environmental outcomes and a better user experience.

In an effort to increase the range of LEED resources for Canadians and follow an internationally consistent approach to how LEED is tailored to different regions of the world, the CaGBC will not be developing stand-alone Canadian rating systems. Instead, the CaGBC will streamline development work by providing Canadian options for demonstrating compliance – termed Alternative Compliance Paths – within the international rating systems.

Alternative Compliance Paths, or ACPs, will allow the CaGBC to identify equivalent means of demonstrating compliance to the credit requirements. For example, where an equivalent Canadian reference standard exists, an ACP can allow for the use of that standard.

This model for tailoring LEED to the Canadian market will simplify the development process and allow ALL the LEED rating systems to be made available to Canadians.

The Canadian Alternative Compliance Paths are available on our LEED v4 Resources web page.

Better user experience

Applying ACPs will help further improve the user’s experience of LEED, allowing project teams to benefit from more regular errata and upgrades to rating systems and tools while leveraging LEED Online, an online platform that helps coordinate and expedite the submission and certification processes.

CaGBC will continue to provide certification reviews to ensure an appreciation and understanding of the unique Canadian context. We will continue to provide local support for any questions and issues that may arise during the design, construction, and certification of projects.

The CaGBC is committed to offering Canadian clients LEED certification services in both official languages and is working with the USGBC to determine the appropriate model for offering French language services.

There are a number of further improvements coming with LEED v4, including web-based reference guides and simplification of the documentation and submittal requirements. CaGBC will be posting new information as it becomes available, so check back regularly and be sure to read our LEED Technical Bulletins, free to all National and Chapter members - to sign-up, simply send us an email.
