LBC, ZC, ZE Program Change Guides

April 5, 2024. ILFI is excited to announce important updates and transitions in our certification programs! These changes are designed to elevate the impact of our Living Building Challenge (LBC), Zero Energy CertificationTM (ZE), and Zero Carbon CertificationTM programs, enabling a clearer understanding of the requirements. The revisions include transitioning from Living Building Challenge 4.0 to 4.1 and updating the Zero Carbon and Zero Energy certification programs from their 1.0 versions to 1.1. Additionally, we have aligned within and between the Energy Petal of the LBC, ZC, and ZE to provide a cohesive and streamlined certification experience. With the updates, Core Green Building Certification is now officially a pathway within LBC (like Petal). Project may register for any of these programs until June 30, 2024. After that date, the LBC 4.0, Core 1.0, and ZE and ZC 1.0 programs will no longer be open for registration.
