Which items are included in the Construction HVAC Commissioning phases?

• A. Identify commissioning scope; develop commissioning test details; Commissioning authority reviews contractor submittals; Coordinate commissioning process through plan, meeting, and schedule; Carry out and document system verification checks; Observe and document equipment and system start-ups; TAB agency completes and documents test and balance work.
• B. Only submittal reviews and approvals.
• C. Design reviews and energy modeling.
• D. Post-occupancy evaluation only.

Answer: (A)

In the construction HVAC commissioning phase, the focus is on planning, executing, and documenting how the installed systems meet the design intent. The best choice walks through the full set of construction-phase activities: start by identifying the commissioning scope so everyone knows what will be tested and verified; then develop the commissioning test details that define how acceptance will be demonstrated; have the commissioning authority review contractor submittals to ensure they align with the testing requirements and performance criteria; coordinate the overall commissioning effort through a plan, meetings, and a schedule to keep activities on track; carry out and document system verification checks to confirm that components and sequences operate as intended; observe and document equipment and system start-ups to verify proper commissioning progress and capture any issues; and ensure the TAB (testing, adjusting, and balancing) agency completes and documents the test and balance work so airflow and hydronic balancing meet design targets. This collection of activities represents the hands-on, collaborative, documentation-heavy work that defines construction-phase Cx, ensuring the installed HVAC system functions as intended before occupancy. The other options don’t fit this phase: submittal reviews alone are a narrow activity not encompassing testing and verification; design reviews and energy modeling belong to the design phase rather than construction; post-occupancy evaluation occurs after occupancy, not during construction.
