Hello everyone,
Since I now have to decide which wall or roof penetrations we need to use for the fresh air intake and exhaust air, I am looking into the various options available on the market.
On the north side, we have the possibility to take in fresh air through the gable. The north gable faces the street, so the solution should also look decent.
The idea is to route the exhaust air through the roof, but 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 that from the street side you see one full story and the pitched roof with the attic and loft. The heat recovery ventilation unit will be installed in the loft.
So far, I haven’t found a fresh air intake and exhaust air solution that really convinces me.
What have you installed, and what makes sense?
We have a planner for the heat recovery ventilation system, but I want to take a broader look at what is available.
Regards,
Micha

Yes, I’ve also heard about the snow issue. But there are also “roof tiles with a small chimney attached” (please don’t ask me for the exact name). With that, your air intake would be about 40-50 cm (15-20 inches) above the roof. And how often do you have 40 cm (15 inches) of snow on the roof?
Best regards,
Andreas

There is a stainless steel grille on both the north and south gable, powder-coated to match the color of the windows.
It looks good—our mechanical ventilation system is also installed in the attic.

Sure, if I put a ladder there, I can reach it from the outside – but what for?
