“All of the green building programs that exist in the world are built around a notion of doing less harm, so we turned that on its head and we’re trying to define what ‘good’ looks like, which is a very different thing,” McLennan says. “Instead of buildings that are less likely to give you cancer, how about buildings that can’t give you cancer? Instead of buildings that produce less pollution than the average building, how about a building that produces no pollution? So, it’s a very different way of thinking, and it is a very challenging program because of that.”
