Double-flow gentle ventilation with heat recuperator. Type 1

This ventilation system is the most common system in MINERGIE buildings. It is suitable for both renovations and new construction. Heat recovery for the preheating of the supply air reduces heat loss due to air change.

Residential buildings require a central or adapted facility for each dwelling with one-storey or multi-storey operation.

All heated rooms in an apartment or building must be mechanically ventilated.
