How did GBI become an ANSI Accredited Standards Developer?
The initial 2005 standards development process resulted in the ANSI/GBI 01-2010: Green Building Assessment Protocol for Commercial Buildings. The 2010 standard was updated and released in 2019, 2021 and again in 2024 as ANSI/GBI 01-2024: Assessment Protocol for Design, New Construction, and Major Renovations. GBI’s second standard, ANSI/GBI 02-2023, Assessment Protocol for Existing Buildings was published by ANSI in summer 2023 and revised again in 2025. GBI is currently in the process of developing two new green building standards, one on Core and Shell and one on Sustainable Interiors.
