Guide pratique sur la modulation des debits de ventilation. Practical guide for the modulation of ventilation losses.

In order to adapt ventilation losses to the actual use of the premises one must aim to control the energy loads due to air renewal while at the same time ensuring the maintenance of good indoor air quality for comfort and hygiene for the occupants. The principle applications are premises presenting wide variations in occupation: number of occupants, but also effective hours of use. These systems are effective and economic, but they must be designed and installed correctly.
