Extracted Content
Core and Shell Development Applicable to whole buildings of various use types that are either new construction or undergoing major renovations and at least 40% of the gross floor area is incomplete. Incomplete: does not have its basic floor, wall, and/or ceiling finishes installed, or essential mechanical, electrical, plumbing systems (or fixtures) necessary to occupy the space for its intended use, within the contracted scope of work.
LEED FOR INTERIOR DESIGN AND CONSTRUCTION (ID+C)
Commercial Interiors Applicable to interior renovation projects of commercial spaces (that have no scope for the exterior shell of the building and/or site work). The team installs movable furnishings, fixtures, and equipment (FF&E) to support the intended regular operations of the space.
LEED FOR BUILDING OPERATIONS AND MAINTENANCE (O+M)
Existing Buildings Applicable to existing buildings projects focused on operational improvement. This rating system focuses on whole buildings that have been fully operational and occupied for at least one year. Focusing on performance-driven strategies and outcomes allows buildings in use to achieve greater efficiency.
PROJECT TYPE REQUIREMENTS
A LEED project must have its entire gross floor area certified under a single rating system (LEED BD+C , either New Construction or Core and Shell; LEED ID+C: Commercial Interiors; or LEED O+M: Existing Buildings) and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type.
However, in some prerequisites and credits, there may be requirements identified for specific project types such as schools, warehouse and distribution centers, health care, or residential.
Project type requirements must be met if 60% or more of the gross floor area of a project is comprised of that project type. For example, if a project is 75% residential and 25% retail, that project must follow the residential requirements in the rating system. In the Core and Shell Rating System or in a New Construction/Major Renovation project with incomplete space, the use type of the incomplete space must be based on the expected future use.
