The LEED for Interior Design and Construction (LEED ID+C) rating systems apply to projects that are a complete interior fit-out. If a company rents an office building and decides to design and construct the interior office space, the LEED ID+C: Commercial Interiors rating system can be used to LEED-certify the office.
1) LEED ID+C: Commercial Interiors
This is for interior spaces dedicated to functions other than retail or hospitality. Think about a LEED-certified core and shell office-building project in which the developer was not involved in the design and construction of the tenant spaces. In this scenario, the tenants may decide to get a LEED ID+C: Commercial Interiors certification for their office spaces, which would only cover the interior fit-out design and construction work.
2) LEED ID+C: Retail
This is for the design and construction of interior spaces used to conduct the retail sale of consumer goods. It includes both direct customer service areas (showroom) and preparation or storage areas that support customer service.
3) LEED ID+C: Hospitality
This is for the design and construction of interior spaces dedicated to hotels, motels, inns, or other businesses within the service industry that provide transitional or short-term lodging with or without food.
