| USGBC | 2023 | 312 |
The LEED v4.1 evolution for the design and construction of full buildings focuses on accessibility, the most current standards and real-world project experiences. This rating system is for buildings that are new construction or major renovations. At least 60% of the project’s gross floor area must be complete by the time of certification (except for LEED BD+C: Core and Shell). You must include the entire building’s gross floor area in the project.
