Owner’s Operating Requirements

The Owner’s Operating Requirements (OOR) are developed by the Commissioning Provider or reviewed for updating early in the Retrocommissioning process. The OOR identifies and documents the owner’s comfort requirements such as space temperature, humidity and outside air fractions, along with the building schedules. A primary objective for compiling and clearly documenting this information is to ensure that, in the course of the retrocommissioning project, those involved remain sensitive to the owner’s needs. This is especially critical for multi-use facilities where different pressure differentials between spaces as well as different humidity, temperature and schedules can exist. Clearly understanding the owner’s needs for the overall building and special areas can greatly reduce mistakes and unwanted disruptions to occupant spaces. The following presents both a template and a completed sample to assist Providers in documenting the Owner’s Operating Requirements for a retrocommissioning project for an office building. Building types such as research laboratories, hospitals and educational institutes would most likely have more complex requirements and is beyond the scope of this document. This document is meant as a starting point for documenting the OOR in a typical office building.
