Question

By utilizing a strategy called demand control ventilation, DCV, the amount of outside air being brought into the building can be varied based on the actual occupancy level in the structure. What is the strategy called that allows the variation of outside air based on occupancy level?

1) Demand Control Ventilation
2) Variable Air Volume
3) Occupancy-based Ventilation
4) Dynamic Ventilation

Answer 1

The strategy allowing variation of outside air based on occupancy level is called Demand Control Ventilation (DCV).

Step-by-step explanation:

The strategy that allows the variation of outside air based on occupancy level is called Demand Control Ventilation (DCV). This is a smart and energy-efficient way to manage the quality of indoor air and ensure that it is continuously replaced with fresh outdoor air according to the actual number of people present in the building. By doing so, buildings can prevent the increase of pollutant levels that may occur due to low air exchange rates, especially when infiltration, natural ventilation, or mechanical ventilation is not sufficient.
