The Living Building Challenge is a certification program that defines the most advanced measure of sustainability in the built environment possible today and acts to diminish the gap between current limits and ideal solutions. It is comprised of seven performance areas, or ‘Petals’, sub-divided into a total of twenty imperatives, each of which focuses on a specific sphere of influence.
