Measuring Carbon Dioxide Inside Buildings – Why is it ...

necessary, consider installing CO 2 sensors to continuously monitor the CO 2 levels in the building. The HVAC control system can use the CO 2 values to automatically modulate the volume of OSA that is brought in so indoor CO 2 is maintained at or below a preset target concentration. This strategy is known as Demand Controlled Ventilation (DCV). DCV systems are especially useful for spaces that ...
