CO2-based demand control for coach ventilation |
|
evaluated |
|
|
|
The ventilation of confined spaces can be controlled according to demand by using CO2-concentration as an indicator for occupancy. This concept can be applied to railway passenger coaches and saves energy since less outside air has to be heated or cooled to inside temperature.

|
Market potential outside railway sector: small |
|
|
|
|
|
CO2-controlled ventilation is seen as especially promising for buildings with a high variation of occupancy and high occupancy peaks, such as cinemas, theaters, classrooms, meeting rooms and retail establishments. Its market is therefore limited to a certain class of buildings/establishments. |
