FAQ - Ventilation of the building
Energy Recovery ventilation (EVR)
This system allows limiting the heat losses inherent in the ventilation. It uses the heat from stale air before it is expelled from the house, to warm the fresh air coming from outside.A fan pulses the fresh and also preheated air in the main rooms through insufflation vents. Such equipment allows the most efficient one to recover up to 90% of the heat of the extracting air.
