The Living Building Challenge® (LBC) is a certification program, advocacy tool, and philosophy defining the most advanced measure of sustainability in the built environment today. As a certification program, it addresses all buildings, landscapes, and infrastructure projects, at all scales, and is an inclusive tool for transformative design. Whether the project is a single building, a renovation, or a park, the Living Building Challenge provides a framework for design, construction, and improvement of the symbiotic relationship between people and all aspects of the built and natural environment.

The Core Green Building Certification℠ (Core) joins the Living Building Challenge as a simple yet holistic framework outlining the ten best-practice achievements that a building must obtain to be considered a green or sustainable building.

This Early Project Guidebook (Guidebook) highlights requirements that determine basic feasibility for LBC and Core projects and provides guidance on elements that classify the project for purposes of certification, including Typology, Project Area, and Living Transect designation.

Additional information about registration and certification for LBC and Core can be found here and on the ILFI website.
