HVAC Controls 26408-23 Practice Test

The main idea is that control strategies come from two guiding documents: the owner’s needs and the design blueprint. The owner requirements describe what the building must achieve in terms of performance, comfort, energy use, and reliable operation. The basis of design translates those needs into concrete technical directions: the control philosophy (how the system will be regulated), the sequences of operation (the exact steps equipment follows under different conditions), and the instrumentation choices (which sensors and meters to use and where to place them). When you design the control strategy, you’re turning the owner’s needs into actionable controls that follow the intended sequences and rely on the chosen sensors and equipment. For example, if the owner requires energy-efficient cooling with occupancy-based ventilation, the BOD would specify the control approach, the order in which equipment should operate, and the specific sensors to monitor—so the system behaves as intended. These documents guide commissioning and ensure performance; other topics like budgets, warranties, or purely architectural concerns don’t define the control approach in the same way.
