The United States Green Building Council (USGBC) launched the newest version of its Leadership in Energy &
Environment Design (LEED) v4 rating system in November of 2013 at Greenbuild International Conference and Expo. The updated version of the rating system will be incorporated into the credential exams by the end of June of 2014, so contractors interested in taking the new exam will need to get up to speed on LEED v4.
The voluntary LEED green building rating system has influenced the design and construction industry since its debut in 1998. The latest version, LEED v4, builds upon the past 15 years and raises the sustainability bar through numerous enhancements and the introduction of the idea of transparency to fulfill USGBC’s vision and mission, “to improve the quality of life by transforming the design, composition, and operation of the places where we live, learn, work, and play within the short space of a generation.”
