The movement for healthier, high-performing buildings has reached a new milestone, as the U.S. Green Building Council (USGBC) issued the 20,000th LEED certification for a commercial project.

In December 2013, USGBC’s Green Building Certification Institute (GBCI) certified the offices and staff services space in the Green Mountain Coffee Roasters (GMCR) plant in Knoxville, Tenn., under LEED for Commercial Interiors (LEED-CI).
