Home / Concept / Passive house / Controlled ventilation and heat recovery

Controlled ventilation and heat recovery 

The passive house standard can't be achieved without a controlled mechanical ventilation system of the premises. It is important because when you open the windows for fresh air during the cold winter or hot summer, huge losses of energy are measured. That is the reason why during these seasons The ventilation system supplies fresh air to all rooms and takes the exhaust air from the service premises.
