What is Chapter 2 of the ACG Cx Guideline?

• A. Quality Assurance
• B. Energy Modeling
• C. Testing Protocols
• D. HVAC Commissioning Cost/Benefit Analysis

Answer: (D)

Chapter 2 centers on measuring the financial value of HVAC commissioning by looking at its cost and benefits. This gives owners and stakeholders a clear economic justification for the work, translating improvements in performance into tangible numbers like energy savings, reduced maintenance costs, longer equipment life, and lower risk of costly failures. The chapter typically guides how to quantify these benefits, estimate the costs of the commissioning effort, and compute metrics such as payback period, net present value, and return on investment. Understanding this analysis helps determine whether the commissioning effort is worth pursuing and informs decisions about scope and investment. While quality assurance, energy modeling, and testing protocols are important topics in other contexts, the cost/benefit analysis focus is what ties the technical work of commissioning to business value.
