The Living Building Challenge is a groundbreaking green building certification program created by the International Living Future Institute. It promotes the development of buildings that are environmentally sustainable, socially just, and aesthetically pleasing. The LBC is organized into seven performance categories, known as "Petals":
Each Petal contains specific requirements, called "Imperatives," that must be met for certification. The ultimate goal of the LBC is to inspire the creation of buildings that function as cleanly, beautifully, and efficiently as nature itself.
