ASHRAE BUILDING COMMISSIONING PROFESSIONAL (BCXP)
EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
BCxP Coverage Areas (Short Summary)
Commissioning Process Fundamentals: ASHRAE Guideline 0, Owner’s Project Requirements, Basis of
Design, and lifecycle commissioning principles.
Pre-Design and Design-Phase Commissioning: Establishing OPR, reviewing design documents, and
integrating commissioning into project delivery.
Construction-Phase Commissioning: Submittal reviews, site observations, issue tracking, and contractor
coordination activities.
Functional Performance Testing: Developing test procedures, executing tests, documenting deficiencies,
and verifying system operation.
HVAC Systems Commissioning: Air distribution, hydronic systems, controls, economizers, chillers, boilers,
and variable flow systems.
Building Automation and Controls: Sequences of operation, trend analysis, alarms, setpoints, and
interoperability considerations.
TAB and Verification: Testing, adjusting, balancing, and validating measured performance against design
requirements.
Documentation and Reporting: Commissioning plans, test forms, logs, reports, and turnover
documentation.
Existing Building Commissioning and Ongoing Commissioning: Retro-commissioning, monitoring-based
commissioning, persistence, and operational optimization.
Professional Practice and Project Management: Communication, ethics, risk management, scheduling,
scope control, and stakeholder engagement.
Question 1
According to ASHRAE Guideline 0, what is the primary purpose of the Owner’s Project
Requirements document?
A. Define contractor installation methods for construction activities
B. Establish measurable owner expectations for building performance and operation
C. Replace technical specifications during bidding activities
D. Provide warranty documentation after occupancy
Correct Answer: B
,Rationale: The OPR defines the owner’s functional, operational, and performance
expectations and becomes the benchmark for design, construction, testing, and
acceptance activities.
Question 2
During project planning, which commissioning activity provides the greatest opportunity
to reduce future operational problems?
A. Reviewing contractor payment requests
B. Conducting deferred seasonal testing
C. Developing and validating the OPR before design begins
D. Performing warranty inspections
Correct Answer: C
Rationale: Establishing a clear OPR early influences all downstream design and
construction decisions and prevents many costly operational deficiencies.
Question 3
A commissioning professional reviews the Basis of Design primarily to verify that it:
A. Matches shop drawings exactly
B. Includes serial numbers and warranties
C. Responds appropriately to the Owner’s Project Requirements
D. Eliminates the need for testing
Correct Answer: C
Rationale: The BOD explains how the design team intends to satisfy the OPR and
documents assumptions, calculations, and selected system approaches.
Question 4
Which commissioning document should be updated continuously as issues are identified
and resolved throughout the project?
,A. Project charter
B. Commissioning issue log
C. Final TAB report
D. Record drawing index
Correct Answer: B
Rationale: The issue log is a living document used to track deficiencies, responsibilities,
corrective actions, and verification of resolution.
Question 5
What is the most appropriate response when a functional test reveals a sequence-of-
operation failure?
A. Modify the control program immediately
B. Ignore the failure if the system eventually starts
C. Document, communicate, and verify correction through retesting
D. Accept the condition if the contractor disagrees
Correct Answer: C
Rationale: Commissioning professionals identify, document, communicate, and verify
correction of deficiencies rather than making unilateral system changes.
Question 6
In a design review, which comment is most valuable from a commissioning perspective?
A. Increase the specification font size
B. Economizer high-limit sequence is not coordinated with energy recovery operation
C. Add a revision date to the title block
D. Alphabetize equipment schedules
, Correct Answer: B
Rationale: Commissioning reviews focus on operability, controllability, maintainability,
and system coordination rather than drafting preferences.
Question 7
Why is functional performance testing performed after startup and TAB activities are
substantially complete?
A. To reduce meetings
B. To evaluate systems under intended operating conditions
C. To avoid reviewing sequences
D. To eliminate trend logging
Correct Answer: B
Rationale: Functional testing is meaningful only when systems are started, adjusted,
balanced, and operating near intended conditions.
Question 8
A commissioning plan should include scope, roles, schedules, testing requirements, and:
A. Contractor labor rates
B. Issue management and documentation procedures
C. Furniture procurement requirements
D. Real estate milestones
Correct Answer: B
Rationale: Effective commissioning plans define how issues will be documented,
communicated, resolved, and reported.
Question 9
Which activity is typically part of construction-phase commissioning?
