The type of demand-control strategy used should be specified! DCV stands for Demand- Controlled Ventilation, which means that the ventilation rate is controlled automatically, and in real-time, according to a demand measured at room-level. This implies that a DVC system must have room sensors which give a measure of the indoor air quality in each room. This signal is then used to control the ventilation rate according to the desired indoor air quality. It is necessary to specify quantitative objectives in order to obtain a system that fulfills the expectations. This chapter provides a quick introduction to various DCV systems.
