Yes, but since we go in and out a lot, the blinds would be running permanently.
You can then work well with canopies, umbrellas, sun sails, or plants like trees.
Cooling via the floor has also been discussed extensively here in the forum. It gives cold feet but not a cool head.
Basically, that is wrong at first.
It is true that the floor naturally has to be somewhat cooler than the room air in order to cool it.
However, one works with small temperature differences so that the floor does not become unpleasantly cold and at the same time the room air is pleasantly tempered.
Of course, there are many fans of air conditioning here, but mostly the advantage of dehumidification is emphasized, which in this case is actually disadvantageous.
The passive house is designed for maximum heat storage.
That is not correct.
A passive house is well insulated.
As a result, it correctly retains heat well inside, but at the same time it also prevents heat from outside from entering inside.
With 6m floor-to-ceiling windows facing west in the open-plan room, it is like an oven. It gets very warm very quickly, even in winter.
Sounds a bit like poor planning, but can be well corrected with the points mentioned above.
As said, temperature is regulated by the air conditioning. Humidity hopefully soon by the EWT.
The EWT can only recover moisture that is inside the house.
If the air conditioning continues to remove moisture, it will be difficult for the EWT to do its work.
