Update the OPR to reflect occupancy and operational conditions
This guide covers Stage 4, Step 5 of the ASHRAE commissioning process: updating the Owner's Project Requirements (OPR) during occupancy and operations. It outlines how to separate requirement evolutions from operational deficiencies, conduct structured impact assessments, and secure formal Owner acceptance. You will also learn how to cascade approved updates to the Basis of Design (BOD) and Systems Manual, and manage the transition from OPR to Current Facility Requirements (CFR) for ongoing commissioning.
