What is a Credit Interpretation Ruling (CIR) in LEED?

After the project is registered at LEED Online, if a project team has questions about the technical details of a prerequisite, credit, or MPR, a CIR is issued to ask for clarification.

Sometimes the reference guide will not be able to provide all the information regarding the achievement of a particular prerequisite/credit, and, in that case, the project team would submit a CIR through LEED Online and ask for a clarification. One CIR can be sent to clarify a single question, and project teams can submit an unlimited number of CIRs. A CIR has a fixed cost of $220 for both USGBC members and nonmembers.

CIRs are administered by the GBCI, and the Credit Ruling Committee reviews the CIR in two to five weeks, concluding the process by clarifying the question asked.
