Commissioning Study Guide
This comprehensive practice guide is designed for professionals
preparing for the AABC Commissioning Group (ACG) Certified
Commissioning Authority (CxA) certification exam. It covers all key
knowledge domains, including the five phases of commissioning,
team structures, core documentation, and HVAC system-specific
procedures, aligned with the official ACG Building Systems
Commissioning Guideline.
SECTION 1: CORE COMMISSIONING CONCEPTS &
DOCUMENTATION (Questions 1-25)
Question 1
Which document defines the measurable performance criteria that the
building owner expects from new construction?
,A) Construction Schedule
B) Owner's Project Requirements (OPR)
C) Systems Verification Checklist (SVC)
D) Functional Test Procedure (FPT)
Answer: B
Rationale: The Owner's Project Requirements (OPR) captures the
owner's measurable performance expectations and serves as the
baseline for all commissioning activities. It is developed at the
project's inception and guides the entire commissioning process.
Question 2
In the commissioning authority (CxA) contract, the term "independent"
primarily refers to:
A) The CxA being employed by the owner's design team
B) The CxA having no financial relationship with the contractor or
vendor
C) The CxA's ability to perform testing without supervision
D) The CxA's authority to approve construction documents
Answer: B
Rationale: Independence means the CxA must not have contractual or
financial ties that could bias their verification activities. The CxA
works on behalf of the building owner to verify that systems are
installed and perform according to the design and OPR.
,Question 3
Which ASHRAE guideline specifically addresses the overall
commissioning process?
A) ASHRAE Guideline 0
B) ASHRAE Standard 90.1
C) ASHRAE Guideline 1.1
D) ASHRAE Standard 202
Answer: A
Rationale: ASHRAE Guideline 0, "The Commissioning Process,"
provides the overarching framework for all commissioning activities.
The ACG Commissioning Guideline aligns with and expands upon this
foundational document with practical application details.
Question 4
The primary purpose of the Deficiency Log (Issues Log) is to:
A) Record all change orders issued by the owner
B) Track non-conformances, corrective actions, and their resolution
status
C) List all equipment warranties and expiration dates
D) Document the project budget overruns
Answer: B
Rationale: The Deficiency Log captures all identified deficiencies,
assigns responsibility for corrective action, and monitors the closure
status to ensure all issues are resolved before substantial completion.
It is a critical tool for quality assurance.
, Question 5
Which document is used to confirm that a system's components have
been installed correctly before functional testing?
A) Owner's Project Requirements (OPR)
B) Systems Verification Checklist (SVC)
C) Energy Model Report
D) Warranty Register
Answer: B
Rationale: The Systems Verification Checklist (SVC) is used during the
Construction Phase to verify that equipment and components are
installed correctly before start-up and functional testing.
Question 6
What is the primary purpose of a Training Plan in the post-acceptance
phase?
A) Provide a schedule for future capital improvements
B) Ensure that operators and maintenance staff understand system
operation, troubleshooting, and maintenance procedures
C) Document the building's energy consumption for the first year
D) List all warranty contacts for equipment vendors
Answer: B
Rationale: The Training Plan ensures that the owner's operations and
maintenance staff are adequately trained to operate and maintain the
building systems as intended. Proper training is essential for
maintaining system performance and efficiency.
