Demand-Controlled Ventilation: Fresh Air Only When You Need It

Balancing the need for fresh air with minimizing energy use is difficult. Demand-controlled ventilation is the responsive solution.

by Candace Pearson

People often talk about the “energy penalty” associated with more fresh-air ventilation. Some level of fresh air is needed for human health and comfort, but pulling in and conditioning fresh air negates hard-earned efficiency measures.

Demand-controlled ventilation is a way to reduce that energy penalty by pulling in fresh air only when it is needed, and shutting off when it is not.
