Beginning June 1, 2015, all projects that register for LEED certification will be required to use LEED version four (LEED v4). LEED v4 introduces a number of new and revised prerequisites and credits, as well as updated reference standards for existing credits. LEED v4 is different from current and past versions of the rating systems, with a much clearer focus on measured performance; to meet those new performance standards, LEED v4 requires a new facility management approach to LEED.
The latest version of the USGBC's green building rating systems was officially released at the Greenbuild 2013 conference in Philadelphia, after an in-depth public comment process and a beta test of more than 100 projects. It was well received by USGBC membership, which voted by an overwhelming 86 percent to approve the new rating system.
LEED v4 will be a significantly different experience, even for project teams that have certified many projects under previous versions. Becoming familiar with key changes to the rating system as well as lessons learned from one of the pilot projects can help facility managers and project teams understand practical ways to take advantage of LEED v4.
Here are some of the most pertinent changes to the credits in each category from the Building Design and Construction (BD+C) and Interior Design and Construction (ID+C) systems.
The first change project teams and facility managers will notice is that Sustainable Sites credits have been separated from Location and Transportation credits. Sustainable Sites credits focus on optimizing the project site, while Location and Transportation credits reward higher density development well served by amenities and alternative transportation infrastructure.
LEED v4's new and updated water prerequisites require whole-project metering, 30 percent irrigation savings, and revised minimum efficiency standards for kitchen equipment and appliances.
