ASHRAE BUILDING COMMISSIONING PROFESSIONAL (BCXP) EXAMINATION 350 PRACTICE QUESTIONS WITH ANSWERS AND RATIONALES

ASHRAE BUILDING COMMISSIONING PROFESSIONAL
(BCXP) EXAMINATION 350 PRACTICE QUESTIONS
WITH ANSWERS AND RATIONALES


SECTION 1: MANAGING COMMISSIONING PROJECTS (Questions 1–80)


Question 1
During which project phase should the Owner's Project Requirements (OPR)
document be initially developed?
A) Construction
B) Design Development
C) PreDesign
D) Occupancy


Correct Answer: C


Rationale: The OPR must be developed during predesign to guide all
subsequent commissioning activities and design decisions. Initiating the OPR
later undermines its ability to establish performance expectations from the
outset.




Question 2

,According to ASHRAE Guideline 0, what is the primary purpose of the
Commissioning Process?
A) To test equipment at startup
B) To verify that the facility and its systems meet the Owner's Project
Requirements
C) To reduce construction costs
D) To replace the need for quality control


Correct Answer: B


Rationale: The core goal of commissioning is to ensure that the delivered
building aligns with the documented OPR. It is a quality focused process, not
merely a testing phase.




Question 3
What is the relationship between the Basis of Design (BOD) and the Owner's
Project Requirements (OPR)?
A) The BOD replaces the OPR after construction starts
B) The BOD translates the OPR into technical design solutions
C) The OPR is used to correct the BOD
D) There is no relationship


Correct Answer: B

,Rationale: The OPR defines the "what" (goals and requirements), while the
BOD defines the "how" (technical assumptions and systems) to achieve those
goals. The BOD must align with the OPR.




Question 4
Who is primarily responsible for generating and updating the Basis of Design
(BOD) document during the design phase?
A) The Commissioning Authority
B) The General Contractor
C) The Design Engineer
D) The Owner's Representative


Correct Answer: C


Rationale: The Basis of Design (BOD) is written by the design team (architects
and engineers) to explain how they intend to meet the Owner's Project
Requirements. It includes design assumptions, system selections, applicable
codes, and performance criteria.




Question 5
What is the primary purpose of a commissioning process?
A) To ensure all equipment is installed correctly

, B) To verify that building systems perform interactively according to design
intent and the owner's operational requirements
C) To reduce construction costs
D) To test all equipment before occupancy


Correct Answer: B


Rationale: The commissioning process is a quality assurance process to help
ensure all building systems perform interactively and according to the design
intent and the owner's operational requirements. It goes beyond simple
equipment testing to verify integrated system performance.




Question 6
Which document defines the owner's goals, expectations, and performance
requirements for a building project?
A) Basis of Design (BOD)
B) Owner's Project Requirements (OPR)
C) Commissioning Plan
D) Systems Manual


Correct Answer: B


Rationale: The Owner's Project Requirements (OPR) document defines the
owner's goals, expectations, and performance requirements for the building
project. It serves as the foundation for all commissioning activities.
