Wall or roof penetrations (external/supply air): how did you install them?

Hello everyone,

since I now have to decide which wall or roof penetration we need to use for supply and exhaust air, I am dealing with the various alternatives on the market.
On the north side, we have the possibility to get fresh air at the gable. The gable on the north side faces the street, so the option should also look reasonable.
The idea for the roof would be to vent the exhaust air, and the south gable can also be used for exhaust air. The south gable faces the garden.

We are building a house on a slope, which means from the street side you can see 1 full floor and the pitched roof with attic and loft. The controlled residential ventilation unit is to be installed in the loft.

So far, I have not found any option for supply and exhaust air that really convinces me.

What have you installed and what makes sense?
A planner for the controlled residential ventilation is available, but I want to look beyond the usual things myself to see what is out there.

Best regards
Micha

I found the inlets/outlets of Vallox quite okay

Do you have a picture of that, please?

Hi,

If the device is located in the attic, the geothermal heat exchanger option is obviously off the table...

There are those roof outlets that basically replace a roof tile. It then looks somewhat like a gas heater chimney.

I wouldn't take the outside air from the street side if the street is more than just lightly trafficked. One smelly car is enough and you have the odor throughout the whole house.

If you build with a fireplace, it would be important to keep the outside air intake as far away from the chimney as possible.

So we don't have a chimney, the gas condensing boiler snorkel is somewhere else. The street is only used by those who live there plus some visitors. So absolutely negligible, I think. There are only 17 houses in the entire area and our building plot is in the middle of the area.

Ok, that's of course something else. Then just imagine placing two of these roof penetrations on the roof and the job is done. No core drilling, no damage to the insulation system, and you actually don't even see them. All perfect!

Best regards,

Andreas
