Bauhaus concrete villa with core insulation - experiences

Hello montessalet, I understandably will not disclose exact costs. Now to the dimensions. Our pool is 20 meters long and 3.42 meters wide (wider than in the shown view). It has an increased water depth and there will also be an (Infinity) overflow pool over the entire 20 meters. Stainless steel is, as you correctly said, the luxury option. The cover alone at this length is expensive, and with polycarbonate you can almost double the price.

Sealed with foil, the entire pool technology, cover only made of PVC, no overflow pool and WITHOUT all the concrete work it would already be close to six figures. Ours will cost more than double that.

Depending on what and how much you can do yourself it will be cheaper. Also, our pool dimension is certainly not average. A "normally" sized pool with good technology can be realized for well under 50k. With steel wall pools, etc., it can be cheaper too. But this is not comparable. The next point is whether and how you want to heat it... Is your drainage sufficient to handle the backflushed water? (usually about 1m3 in 2-3 minutes)

If you have further questions, just get in touch. Regards

Hello Alex, we thought about that for a long time.
In the end, we decided against working with fan coils or anything similar.
There is an additional split unit that pre-cools the intake air. The air is also guided about 40 meters along the ground beforehand.
Cooling with air is always a worse choice and only really makes sense from an air change rate of 4 onwards. But we don’t want 18°C inside when it’s 30°C outside. It’s more about buffering the temperature peaks.
Due to the massive construction, shading, and partial covering of the glass surfaces, it should work.

The solar gain is just incredible. It's not about 18 degrees, but about all-day overheating. However, the automation of shading certainly helps with that. The throughput of a ventilation system is simply far too low to effectively counteract it, even if the supply air is precooled. Air conditioning doesn't have to use split units indoors; you can also install convectors in the floor and the like. Or you can cool via the ceiling without convectors, which also works. I would really have concerns about the amount of glass, probably facing south.
