Optimizing Indoor Air Quality and Energy Efficiency with Demand-Controlled Ventilation (DCV)
Demand-Controlled Ventilation (DCV) represents a strategic control approach that adjusts the volume of ventilation by recalibrating the set points for outdoor air intake flow within an occupied area. This recalibration is contingent upon the dynamic fluctuations in the number of occupants. The primary objective is twofold: to avert inadequate ventilation, which could escalate the potential for compromised Indoor Air Quality (IAQ), and to circumvent excessive ventilation that entails energy wastage.
The most elementary manifestation of DCV entails the modulation of the outdoor air rate through an on/off mechanism, triggered by input from a room occupancy sensor, time clock, or light switch. A more intricate iteration of this approach involves the utilization of a signal that correlates with the quantity of individuals present within a given space. This signal serves to autonomously modulate the quantity of outdoor air being introduced.
It should be duly noted that the application of the aforementioned ventilation strategy facilitates the opportunity to secure LEED credits within the "Indoor Environmental Quality" credit category.
