ᐅ Retrofitting an air conditioning system – will that affect KfW funding?

Good evening everyone,
Since October, we have been living in a prefabricated house built by Hanse Haus. We have been living here for about 5 months now and are very pleased.
However, at the moment, the indoor temperature in each room is between 26°C and 28°C (79°F and 82°F), even though it is similarly warm outside. The only way we can lower the temperature is by opening the windows at night.
We have a KFW55 standard and a Stiebel Eltron LWZ 5s Plus. Unfortunately, it does not have an active cooling function, but we have installed and activated the summer cassette in the menu settings. So far, this has not produced the desired result. The temperature remains the same.
We are now considering adding air conditioning, but we have been clearly advised that this might mean no longer meeting the KFW energy-saving regulation standards, and therefore, it might affect the eligibility for subsidies. Fortunately, it is not very hot outside at the moment, but when it reaches 35°C (95°F) outdoors, the temperature inside the house can easily rise to around 30°C (86°F), which is not exactly comfortable.
Does anyone have advice or experience with retrofitting air conditioning (in specific rooms) or with the same heating system?
Thanks & best regards

Otherwise, this applies to all common air conditioning systems. There are numerous examples of installations that have already paid off. Naturally, this is in residential buildings. It is a heating system that is being supported here.

pagoni202023 Jun 2021 21:22For new residential buildings, there is NO longer any subsidy for air conditioning/air source heat pumps! This is a confirmed statement from my, in my opinion, competent energy consultant as well as from the responsible representative at Daikin.

Since the end of 2020, this is no longer the case. I haven’t thought about it retrospectively anymore; for me, it was enough to know that it would NOT be subsidized for my current new build.T
