-based demand-controlled ventilation (DCV) is one of the strategies that could lower energy use by reducing over-ventilation of buildings (Alalawi and Krarti 2002; Taylor 2006, Stanke 2006). When such strategy is applied by detecting the CO 2 concentration in return air as in most case, it may result in poor air quality inside certain zones in a multi-zone building. In addition, most DCV ...

HVAC – Guide to Demand Control Ventilation

Demand Control Ventilation (DCV) is a method of introducing variable amounts of fresh air "on demand" based on actual occupancy patterns. The system provides a means to adjust the rate of ventilation continuously and automatically. Essentially, the control is achieved by means of a sensor (or a series of sensors) which respond to the variation in occupancy. Output from the sensor is applied to ...
