DOMAIN 1: Managing Commissioning Projects (18
Questions)
Question 1
Which of the following best defines building commissioning?
A) A process of verifying that HVAC equipment meets manufacturer specifications
B) A systematic process of ensuring that a building's systems are designed, installed,
and operated to meet the owner's needs and intent
C) The routine maintenance and repair of building systems throughout their
operational life
D) An inspection conducted by local building authorities to ensure code compliance
Correct Answer: B
Rationale: Building commissioning is defined as the systematic process of verifying
and documenting that building systems perform in accordance with the Owner's
Project Requirements (OPR) and intent. It goes beyond simple code compliance or
manufacturer specifications to ensure integrated, optimized performance across all
systems.
Question 2
A commissioning provider is engaged before schematic design begins. What is
the MOST valuable first action for the provider?
A) Develop final FPT scripts before systems and sequences are designed
,B) Help the owner define the OPR, success criteria, scope, and budget
C) Begin construction observations before design documents are issued
D) Assume responsibility for the design professional's code review
Correct Answer: B
Rationale: Early commissioning value comes from translating the owner's needs into
clear requirements, scope, responsibilities, deliverables, and budget expectations.
These decisions guide later design reviews, testing, training, and turnover.
Question 3
Which role should the Commissioning Authority (CxA) maintain throughout a
project?
A) A senior employee of the design-build firm
B) An independent party hired directly by the owner with no contractual relationship
with the design-builder
C) A representative of the general contractor
D) A subcontractor to the mechanical contractor
Correct Answer: B
Rationale: The CxA must maintain independence to provide objective, unbiased
verification. The CxA is hired directly by the owner and has no contractual
relationship with the design-builder or contractor to avoid conflicts of interest and
ensure technical objectivity.
Question 4
During which project phase should the Owner's Project Requirements (OPR) be
developed?
A) Construction phase
B) Pre-design/planning phase
C) Commissioning phase
D) Post-occupancy phase
Correct Answer: B
Rationale: The OPR is a foundational document developed during pre-design that
captures the owner's functional goals, performance targets, operating needs, and
acceptance expectations. It guides all subsequent design and commissioning
activities.
,Question 5
Which of the following is NOT typically included in the Owner's Project
Requirements (OPR)?
A) Energy efficiency goals and targets
B) Detailed equipment manufacturer model numbers and part specifications
C) Indoor air quality and thermal comfort requirements
D) Occupancy schedules and operational expectations
Correct Answer: B
Rationale: The OPR defines owner goals, performance criteria, and operational
needs. Detailed equipment specifications are generally found in the Basis of Design
(BOD) or construction documents, not in the OPR, which focuses on performance
outcomes.
Question 6
What is the primary purpose of the Commissioning Plan?
A) To document the budget allocated for HVAC maintenance
B) To identify and assign commissioning team roles, define scope, timeline, and
verification procedures
C) To list all building code violations found during construction
D) To provide the contractor with as-built drawings for system installation
Correct Answer: B
Rationale: The Commissioning Plan is a foundational document that outlines the
commissioning process for a specific project. It clearly defines the commissioning
authority's role, establishes the team's authority and responsibilities, delineates the
scope of systems to be commissioned, provides a realistic timeline, identifies
verification procedures, and documents the quality assurance approach.
Question 7
Which document describes how the commissioning process will be executed for
a specific project?
A) Owner's Project Requirements
B) Basis of Design
C) Commissioning Plan
D) Systems Manual
, Correct Answer: C
Rationale: The Commissioning Plan is the document that outlines the scope,
schedule, responsibilities, and procedures for the commissioning process. The OPR
defines owner needs. The BOD describes design approach. The Systems Manual
contains operation and maintenance information.
Question 8
What do OPR and BOD stand for, and what is their relationship?
A) OPR = Operations Plan Revision; BOD = Budget Oversight Document
B) OPR = Owner's Project Requirements; BOD = Basis of Design; the BOD translates
the OPR into specific design solutions
C) OPR = Operational Performance Ratings; BOD = Building Operations Database
D) OPR = Overall Project Requirements; BOD = Building Occupancy Details
Correct Answer: B
Rationale: The OPR captures the owner's goals and expectations. The Basis of
Design (BOD) is the design team's technical response to the OPR, documenting the
systems and strategies chosen to meet those requirements.
Question 9
During which phase of the commissioning process does design review typically
occur?
A) Pre-functional testing
B) Design phase
C) Construction phase
D) Post-occupancy phase
Correct Answer: B
Rationale: During the design phase, the commissioning authority (CxA) performs
design reviews to ensure the design documents align with the OPR and that the
design is "commissionable." This proactive review helps identify potential issues
before they are built.
Question 10
Which phase includes development of the commissioning plan?
