Environmental Product Declaration driver LEED v4 on track for fall launch

A new version of the U.S. Green Building Council’s Leadership in Energy and Environmental Design green building rating system, incentivizing building material or product suppliers to detail their processing or manufacturing methods, is set for rollout at the 2013 Greenbuild Conference and Expo , November 19-21 in Philadelphia.

LEED v4 provides points on projects where suppliers offer Environmental Product Declarations. Developed in accordance with international standards and a transparent verification process, EPD enable specifiers, purchasers and users to compare materials’ or products’ environmental impacts. Early EPD subscribers include U.S. Concrete’s northern California company, Central Concrete Supply, and fly ash-bound brick and paver producer, CalStar Products, Wisconsin.

LEED v4 “challenges the market to make the next leap toward better, cleaner, healthier buildings,” says USGBC Senior Vice President Scot Horst. “I am confident people will also notice the improved usability of the system with [its] documentation process and more resources to support positive action.”

USGBC membership voted to adopt LEED v4, an overall 86 percent favorable tally reflecting 90 percent, 89 percent and 77 percent approval among user, producer and general interest category voters.
