Question 1
Which of the following best defines the primary purpose of building
commissioning as described in ASHRAE Guideline 0?
A) To verify that the construction schedule is maintained throughout
the project
B) To ensure that the owner's project requirements are met and that
building systems perform according to the contract documents
C) To reduce the first cost of construction by eliminating unnecessary
equipment
D) To provide a warranty for all building equipment for a period of five
years
Answer: B
Explanation: ASHRAE Guideline 0 defines commissioning as a quality-
focused process that verifies and documents that the building and its
,2|Page
systems are planned, designed, installed, tested, operated, and
maintained to meet the Owner's Project Requirements (OPR). This is the
fundamental purpose. Option A is incorrect because schedule
management is the responsibility of the construction manager. Option C
is incorrect because commissioning typically increases first costs slightly
but reduces lifecycle costs. Option D is incorrect because commissioning
does not provide warranties.
Question 2
What is the Owner's Project Requirements (OPR) document in the
commissioning process?
A) A detailed list of all equipment manufacturers and model numbers
B) A comprehensive statement of the owner's needs, expectations, and
constraints for the project
C) The construction schedule and milestone dates
D) The budget for the entire construction project
Answer: B
Explanation: The OPR is a foundational document that defines what the
owner expects from the building. It includes functional requirements,
performance criteria, sustainability goals, operational constraints, and
budget limitations. Option A describes equipment schedules. Option C
describes the project schedule. Option D describes the project budget.
Question 3

Which commissioning activity occurs during the planning phase of a
project?
A) Functional performance testing
B) Development of the commissioning plan
C) Systems manual preparation
D) Training of operations staff
Answer: B
Explanation: The commissioning plan is developed during the planning
or pre-design phase of the project. Functional performance testing
occurs during the construction phase. Systems manual preparation and
operations staff training occur during the occupancy and operations
phase.
Question 4
The Basis of Design (BOD) document is typically prepared by which
party?
A) The owner
B) The design engineer
C) The commissioning provider
D) The general contractor
Answer: B
, 4|Page
Explanation: The Basis of Design is prepared by the design engineer or
design team and describes the technical approach and assumptions
used to meet the OPR. The owner provides the OPR, not the BOD. The
commissioning provider reviews the BOD but does not prepare it. The
general contractor does not prepare design documents.
Question 5
According to ASHRAE Guideline 0, which phase of commissioning
involves the verification that systems are installed correctly and
function according to design intent?
A) Pre-design phase
B) Construction phase
C) Occupancy and operations phase
D) Disposal phase
Answer: B
Explanation: The construction phase includes installation verification,
system startup, and functional performance testing. The pre-design
phase involves planning. The occupancy and operations phase involves
systems manual delivery, training, and ongoing commissioning. There is
no disposal phase in Guideline 0.
Question 6
Which of the following is a key benefit of implementing building
commissioning?
