Is an air conditioning system necessary for the attic with a roof pitch of 35 degrees facing south, featuring two roof windows and a dormer on the south side? The rooms on the south side, arranged from west to east, are an office, a children's room, and a bedroom.
Opinions vary widely on this. A heat pump with cooling function and a mechanical ventilation system with heat recovery will be installed.
At the moment, the plan is to at least equip the south-facing rooms in the attic and possibly also the ground floor (living/dining area) with air conditioning.

Yes, I completely agree with you. Having a cool house in the summer is definitely great. I have remodeled our system twice already (due to an increase in the number of residents). So maybe it’s better to do it right once and for all.

The system should also be designed so that you don’t have to think about when to open or close which door to achieve the desired temperature in each room.

Free@Home planned. Although it seems the air conditioning can’t or doesn’t need to be integrated there, since it operates independently via room sensors, right?

Deliverer5 Mar 2020 20:34Air conditioning units are similar to heating systems. Your heater has roughly 7-8 kW. With that, you create a temperature difference of 30-35 K between inside and outside. So why does the air conditioner need 11 kW for a difference of only 10, at most 15 K?
Just a thought to consider.
PS: What kind of premium equipment are these? Even the equity involved seems quite substantial to me...

I just read again in the description of Busch&Jäger free@Home, and it says that air conditioners can be integrated. I will need to clarify that in more detail.

Just something to think about.
PS: What kind of premium devices are these? Even the equity seems quite substantial to me... The equipment for the "Material Only" option comes from Remko (1x outdoor unit MVT 1403 DC, 3x indoor units MXW 204, and 1x indoor unit MXW 524 plus small parts and connection cables). For the "Complete including installation" version, it is 1x Daikin 5 MXM90N outdoor unit, 2x Daikin R-32 wall-mounted Stylish FTXA25AW units, and 3x Daikin R-32 wall-mounted Stylish FTXA20AW units.

Deliverer9 Mar 2020 14:49I can’t say much about Remko (except that I’ve rarely heard of it). Daikin is excellent. I believe the main cost driver with this setup is that these are 4- to 5-zone split systems. Those are quite rare and therefore noticeably more expensive. If it’s going to be that extensive, it might be worth considering more than one outdoor unit. This usually shortens the pipe lengths and thus reduces installation effort, increases reliability, and lowers equipment costs. Of course, unfortunately at the expense of the external appearance...

My parents have a semi-detached house built in 2001 with one and a half floors. I find it unbearably hot upstairs in the summer (like an oven). I’m not sure what improvements have been made in insulation technology over the last 20 years for a one-and-a-half-story house where the bedrooms are upstairs, except that the insulation wool may have become a few centimeters thicker.
Our house has a cold roof with a insulated (24cm (9.4 inches)) concrete ceiling (20cm (7.9 inches)) above the bedrooms (full south-facing side). In summer, when the blinds are down from around 9 a.m., the temperature in the evening before going to bed is about 25°C (77°F), which is just about manageable.
If I were you, I would definitely consider installing air conditioning!

The installation effort and costs were reasonable since it was done entirely DIY.
P.S. The app control works perfectly as well
