Please confirm the application of LEED-NC Version 2.2 to a project on a university campus. The project includes a new addition as well as a major renovation to a portion of an existing building. The major renovation is encircled by a demising wall and is considered by the code definition of a building to be a separate building. Portions of the existing building will not be renovated and will not be included in the LEED project boundary or rating. All of the building is owned and used by the university. The proposed LEED project boundary includes the new addition and the areas of major renovation following the demising wall and excludes the rest of the building. Please confirm this approach.
The inquiry is seeking clarification on defining a LEED project boundary for an existing building with new addition. Per the MRc1 CIR Ruling on 8/27/2007, "A project may determine the LEED project boundary in the existing building as best fits the project, provided this boundary includes all relevant construction work. In addition, the LEED project boundary must remain consistent across all LEED prerequisites and credits. For example, the project team may not include the entire existing building for some credits but only the renovated portions for other credits." The project team\'s approach is correct. Also, if the areas of the existing building are excluded from the LEED project boundary, please be sure to consistently exclude them from any area calculations when submitting for MRc1. Applicable Internationally.
