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.

LEED v4的开发历时三年多，全球数百名志愿者和数千名利益相关者参与其中。与以往的LEED版本相比，LEED v4有潜力推动建筑碳排放的减少，并对人类健康采取更强硬的立场。

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.

与以往相比，现在项目在更广泛的项目类型上使用LEED评级系统。从体育场到会议中心，从商业办公室到医院，每一种空间类型在使用LEED时都有独特的需求和挑战。LEED v4解决了21个不同的市场部门的适应，包括新的和现有的数据中心、新的和现有的仓库和配送中心、酒店、现有的学校、现有的零售和多户中型住宅。To view the rating systems as well as summaries of the changes relative to v2009, check-out ourLEED 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.

可供选择的合规路径，或acp，将允许CaGBC确定显示符合信用要求的等效方法。例如，如果存在等效的加拿大参考标准，ACP可以允许使用该标准。

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.

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 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.

Registration is now open

Registration to the LEED v4 rating systems opened in November 2013.

In order to facilitate the transition to LEED v4, projects will be able to register under the current rating systems until at least 2015. This will provide a period of time during which project teams will have the opportunity to choose which version to register under.
