Precertification is formal recognition by GBCI that the owner or developer has established LEED for Core & Shell certification as a goal. Precertification is unique to LEED for Core & Shell, and projects may pursue it at their discretion. It gives core and shell building owners and developers a marketing tool to attract potential tenants and financiers who recognize the benefits of a LEED-certified building. Precertification generally occurs early in the design process and is based on declared goals and the intent to use green features, not actual achievement of these features.
