Adequate fresh air ventilation is a key piece of indoor air quality. In the past, building ventilation was handled in a largely manual fashion and planned around estimates of the maximum occupancy of a space of a certain size. …And, of course, occupants could just crank up fans or open windows if they felt like the air was getting stuffy.
This was an inefficient, mostly inaccurate and not-too-responsive way to handle things. Accidentally over-ventilating could also drive up energy costs for heating, cooling, or fan operation, while under-ventilating could reduce comfort and threaten compliance with acceptable IAQ standards.
A Demand Control Ventilation (DCV) system automates the process and helps you to maintain excellent air quality for occupant comfort while also reducing energy costs. The DCV system uses sensors to assess current ventilation demands — based on occupancy and various IAQ readings — and introduce fresh air from outside as needed.
For instance, folks might arrive at the office for work in the morning to a quiet, dormant air ventilation system. The DVC system notices that the building is now occupied, and increases the airflow ventilation to rooms where people are now at work. Sensors track CO2, temperature, humidity, room occupancy, and indoor/outside air pressure to keep track of ventilation needs and adjust the system accordingly.
The result? Lower energy costs, optimized ventilation, better IAQ, and a more comfortable building.
A DCV system is only as good as its sensors. If all you’re tracking is occupancy, you’re still running the risk of over or under-ventilating, because the system isn’t taking the status of (and differences between) indoor and outdoor air quality into account. Here are a few of the key sensor types to deploy in your HVAC system’s ducts as well as in critical ceiling or wall-mounted locations for optimal performance:
