Credit Interpretation Request for definition of a "building" This credit interpretation request is to clarify the ruling dated 5/23/2007 which states that the LEED-NC rating system is appropriate for entire buildings. The first part of the question is whether a building per the USGBC is defined by the code definition of a building and has fire rated demising walls around the building OR whether a building per the USGBC is an entire free-standing structure. The second part of the question is relevant if the USGBC determines that a building is an entire free-standing structure. If the area getting a major renovation is separated from other parts of an existing building by a the demising wall and all of the existing building belongs to the same owner (like a higher education or municipal building type and not a landlord-tenant arrangement), can the free-standing structure requirement be waived so the project boundary for LEED-NC is focused on a building separated by demising walls?
The project is requesting clarification of whether a portion of a building separated by a fire rated demising wall is eligible for LEED NC certification or if buildings must be a free-standing structure to qualify. LEED NC can be used to certify new buildings or major renovations of existing buildings. Major renovation includes major HVAC renovation, significant envelope modifications and major interior renovation. Certification of a project will be based on the project\'s own merit and documentation that it meets the prerequisite and credit requirements. Therefore, a portion of a building that is separated by a fire rated demising wall must be able to meet all of the prerequisites and minimum number of credits independently and should have stand alone structural supports, mechanical equipment and similar components. Additionally, the project must determine a consistent LEED boundary for all credits. Applicable Internationally.
