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.

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.
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 the submission process as well as certification review.
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.
