For more detailed drawings refer to ashrae.org or ASHRAE (2007) as-built drawings attached to the owner's project requirements
. System capacities and flow rates are shown in Table 1.
2) Define and document the owner's project requirements
ASHRAE Guideline 0-2013, The Commissioning Process, points out that the basis of design evolves from the owner's project requirements
. An owner may ascribe specific, rather than functional, attributes to the project requirements.
In addition, some of the information in this article series has been adapted from an unpublished NEBB standard titled NEBB Standard Owner's Project Requirements
(OPR) Guideline (draft dated June 20, 2011); and from NEBBs Procedural Standards for Building Enclosure Testing (March 2013).
the Owner's Project Requirements

After completing the Owner's Project Requirements
(OPR) and Basis of Design (BOD) documents, the next step on the path to project success is preparing a detailed, step-by-step Cx Plan.
ASHRAE defines the BOD as "a document that records the major thought processes and assumptions behind design decisions made to meet the owner's project requirements
(OPR)." The design team uses the BOD document to show how their assumptions and specifications will enable the completed project to satisfy the requirements listed in the OPR document.
In addition, some information has been taken from an unpublished NEBB standard, NEBB Standard Owner's Project Requirements
(OPR) Guideline (June 20, 2011) and a "sample" OPR created by NEBB for the fictional "ABC Headquarters Office Building" (Jan.
Develop a complete owner's project requirements
But with design/build projects, it is virtually certain that substantial updates to the basis of design and, in many cases, the owner's project requirements
, will be required.
The process focuses on verifying and documenting that a facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner's Project Requirements
There are multiple reasons for this ranging from not clearly documenting the end goal (owner's project requirements
) to incorrect energy modeling to uncoordinated design to poor workmanship, to improper operation and maintenance, to contractors exemption requirements in their bids.
