Project Registration Details

Project registration details

The International Living Future Institute (ILFI) offers a suite of high performance building certification programs, including the Living Building Challenge (LBC), Core Green Building Certification (Core), Zero Carbon (ZC), and Zero Energy (ZE). These programs are designed to serve as a philosophy and advocacy tool, as well as a third-party certification based on actual performance. For project teams interested in pursuing certification, all four programs follow the same fee structure, services, and registration process.

program fees

ILFI charges fees for Certification based on project size and complexity, however, the fees collected cover less than half of our operating expenses. As a501c3, we seek philanthropic support to cover the majority of our operating expenses so that we can keep our pricing accessible.

Program fees are calculated on a gross floor area basis as shown in the tables below, except for Single Family Residences which are charged a flat fee. This total is a comprehensive fee that covers registration, certain technical support services, two-part third-party audit, and certification. Fee payment occurs in three installments: 25% at Registration, 50% prior to Construction, and 25% prior to the preliminary Ready Audit.
