A » Demand-controlled ventilation (DCV) is an HVAC strategy that adjusts the amount of outdoor air ventilation based on the occupancy or air quality in a space. By using sensors to monitor CO2 levels or occupancy, DCV systems optimize ventilation rates, improving energy efficiency and indoor air quality. This approach ensures that adequate fresh air is provided only when needed, reducing energy consumption and operational costs.
