my architect told me today that, starting in 2009, it is apparently a legal requirement that new buildings with the KfW 40 standard must include either a solar thermal system or photovoltaic panels. We planned to install a water-to-water heat pump and therefore wouldn’t necessarily need a solar system. Photovoltaics are currently not an option for us due to the costs. Has anyone heard about this new regulation?
I would really appreciate any advice on what is mandatory and what can be omitted. I have the feeling that the architect is trying to include all the "new energy technologies" in our house. 😕

hi!
I have also heard about this but understood it differently... the KFW standard describes the potential energy consumption in your house.
With solar panels, you can create more flexibility here...
So your intuition is probably right, your architect wants to "recommend" a solar system so they have more leeway in other areas of energy consumption and planning...
They might mean well, or they might be trying to save on insulation...
As far as I can tell, it is not a legal requirement at this point, but you might want to check out some solar panel offers and calculate the costs over 10 years^^
Heat pumps are usually only suitable for large rooms
