In which phase are functional performance tests on all HVAC systems carried out?

• A. Acceptance
• B. Design
• C. Construction
• D. Post-Acceptance

Answer: (A)

Functional performance tests are used to prove that the installed HVAC systems meet the owner's performance criteria under real operating conditions, including how the controls and sequences work together. These tests are typically done toward the end of the project, during the Acceptance phase, when the owner verifies that the systems perform as designed before final handover. Design focuses on specifying requirements, and construction ensures installations are completed and ready, but the comprehensive verification of performance across all HVAC systems happens at the Acceptance stage. Post-acceptance is after turnover, dealing with issues that arise during operation or warranty periods.
