Without a ventilation system, it is already not permitted under the Building Energy Act (Energy Saving Ordinance) with an increased energy saving standard.
This also applies to the KfW, which bases the Energy Saving Ordinance or later the Building Energy Act.
First of all, you need the space that is associated with costs (fire protection excluded), then the ducts must be maintained.
The energy consumption can be up to 15 times higher because of system losses.
The efficiency of the heat exchangers is now well above the standard values in all good devices.
The disadvantage of decentralized devices is that they are visible on the facade.
Really, is that so?
Strange that the KfW approved me a KfW55 house without a ventilation system. I must have been lucky.
