How do you avoid the worst offenders? How do you use disclosure tools such as HPD, EPD, MSDS, and Declare Label? And how do you spot an information gap? Our Living Building Challenge Ambassadors, Scott Kelly and Chris Lee, answered these questions (and more) during a live interactive webcast with BuildingGreen.com that focused on how to vet material toxicity. More than 100 participants already know the answers, and the webcast is still available for those who don’t.
