Why do you have to have a controlled residential ventilation system for kfw 55?
What speaks against it? We will never have it without again.

I absolutely don't see it that way. Photovoltaics can never offer me the comfort that I get from controlled residential ventilation. Everyone just has different priorities. IMHO: First controlled residential ventilation, then (if there is money left) photovoltaics and not the other way around.But for Controlled Residential Ventilation 55 you don't need Controlled Residential Ventilation. For the 12k €+ you better get a photovoltaic system.
