The Haworth Merchandise Mart showroom was chosen as one of 104 projects to participate in the U.S. Green Building Council’s nationwide LEED-CI pilot program. In 2005, the Haworth showroom became the first LEED-CI Gold certified showroom in the Merchandise Mart. This project set the bar for at least eight other showrooms seeking LEED-CI or LEED-EB certification within the Merchandise Mart.
