the core objective

With the Living Building Challenge 4.1 update, ILFI consolidates the Living Building Challenge framework to include Core as a certification pathway alongside Petal and Living Certifications. The previous Core Green Building Certification 1.0 was a standalone pathway, and this change formalizes Core’s importance as an entry point to the Living Building Challenge. 

Core certification is the entry point for AEC teams and owners to begin their journey toward fully regenerative building practices. With the accountability of a performance-based standard, Core also serves as the foundation for any project pursuing Petal or Living designation under the Living Building Challenge.
