Question 206General Subjects - 1st Asst/Chief

The correct answer is C) A variable air volume system. A variable air volume (VAV) system is ideally designed to serve a large public space. VAV systems can efficiently provide heating and cooling to large, open areas by varying the volume of air delivered to different zones based on the cooling or heating load in that zone. This allows the system to match the air delivery to the actual demand, which is more energy-efficient compared to a single zone system that would over-condition some areas. The other options, such as dual duct and terminal reheat systems, are better suited for more complex, multi-zone buildings rather than a large, open public space.
