Certification Options

Living Building Certification

A Living Building is a demonstration that the built environment can actually help restore the natural environment.  A project achieves Living Building Certification by attaining all Imperatives assigned to its Typology.

Petal Certification

While achieving Living Building Certification is the ultimate goal, meeting the Imperatives of multiple Petals is a significant achievement in and of itself. For this reason, the Living Building Challenge offers Petal Certification. This certification option provides a platform for a project to inform other efforts throughout the world and accelerate the adoption of restorative principles.


  • Project teams may pursue Petal Certification by satisfying the requirements of three or more Petals, including at least one of the following: Water, Energy or Materials.
  • Both Imperative 01: Limits to Growth and Imperative 20: Inspiration and Education must be achieved.
