Looking through the requirements of LEED ND v4 I can only find reference to the OPR in one location - embedded within Appendix 4 as a requirement for GIB prerequisite Minimum Building Energy Performance - Option 2 Prescriptive Compliance. The OPR is usually developed by the Cx, but neither is there a requirement for a Cx as part of LEED ND. There doesn't appear to be much information around on this. Could you please clarify for me the requirement for an OPR as part of LEED ND?
