ᐅ Air Conditioning During the Renovation of an Older Building?

Hello everyone,

we are currently renovating an old building from 1913 and will also be adding a small extension. I would like to prepare practical solutions to enable air conditioning (cooling) for the office (old building) and the bedroom (new building). The goal is to get through the few hot days in NRW, which are likely to increase rather than decrease, without cooling the entire apartment down to 17°C (63°F). This concerns the ground floor apartment, which has a full basement (yes, the extension will also have a basement).

I have a few ideas:

• Prepare ventilation ducts in the basement to blow centrally cooled air into the rooms. The cool air could be generated
• by a central air conditioning unit
• through air ducts in the slab of the new basement (about 40m² (430 sq ft) area)
• Split air conditioning units in both rooms: Both my wife and I find them very unattractive and this would only be the absolute last resort.

I am interested in all opinions, ideas, and experiences on whether this is nonsense or if there are other options I haven’t considered.

Welcome to the forum,
Solution 2 is effective and requires little effort; you can also use it for heating.
Hide 1 outdoor unit,
and 2 indoor units, which also come in attractive designs,
for example, wall-mounted, floor-standing, ceiling units, etc.
Solution 1 would be far too complicated for just a few days of heat.

Thanks 🙂

Do you have example products or search terms? I usually find the indoor units quite unattractive, and since we don’t have a dropped ceiling in our older building, they have to be mounted on the wall somewhere. I could only find something from Daikin that is a bit less ugly than common split units, but attractive (and especially suitable for an older villa with subtle stucco detailing) is something else entirely...

Number 1 does not work. The airflow is far too low, causing excessive condensation issues.

You get used to the appearance of number 2 quickly, especially if it allows you to sleep comfortably during the summer. And almost all manufacturers now offer somewhat more "stylish" units.

Otherwise, consider radiant cooling or chilled ceilings, but these cost several times more.

And the dehumidification is still missing.
