​In demand controlled ventilation (DCV) the ventilation intensity is adjusted to correspond to the true need in order to save energy. It has clear advantages especially when occupancy varies widely, such as in schools, conference centers, and auditoriums. The carbon dioxide level in a space indicates human presence and can be used to control ventilation.

The efficiency of DCV can only be optimized by accurate carbon dioxide sensing. Vaisala CARBOCAP® technology delivers maintenance-free accuracy and performance that lasts. The CARBOCAP® sensor can be used in a wide variety of applications, including variable outdoor CO2 levels or facilities with around-the-clock occupancy such as hospitals, workplaces and residential buildings.
