Building Systems Integration Flashcards

Which HVAC system uses a single duct at a constant volume to condition all zones in a building?

Answer: Single-Zone Constant Air Volume (CAV)

A single-zone CAV system delivers a fixed quantity of conditioned air to one zone without modulating airflow volume.

In plumbing design, what is the purpose of a P-trap?

Answer: To maintain a water seal that prevents sewer gases from entering the building

A P-trap holds a water seal in its curved section, blocking sewer gases and odors from traveling back through the drain into the occupied space.

Which electrical panel component protects circuits from overloads and short circuits?

Answer: Circuit Breaker

Circuit breakers interrupt current flow when a fault or overload occurs, protecting wiring and equipment from heat damage and fire.

What does the term 'R-value' measure in building assemblies?

Answer: Thermal resistance of a material

R-value measures a material's resistance to heat flow; higher R-values indicate greater insulating effectiveness.

Which fire suppression system is most appropriate for a computer server room?

Answer: Clean Agent Suppression System

Clean agent systems use gaseous suppressants that extinguish fire without damaging sensitive electronic equipment or leaving residue.

In a Variable Air Volume (VAV) HVAC system, how is thermal comfort controlled in individual zones?

Answer: By modulating the volume of conditioned air supplied to each zone

VAV systems vary the quantity of supply air delivered to each zone while maintaining a relatively constant supply air temperature.
