ᐅ Enclosing the Vent Outlet on the Exterior of the House – Suggestions?

Hello everyone,

Right where my ventilation outlet exits the house, I want to build part of the terrace. The terrace will be constructed about 1 meter (3 feet) above ground level, so the ventilation practically comes out underneath the terrace. Originally, it wasn’t planned to have a terrace section there – but now it will be. 🙂 The ventilation exits to the outside are already installed and cannot be changed.

From my point of view, I have two options: I could build a substructure that leaves a free space under the terrace, or I could create a kind of drywall construction and "install" a ventilation duct that extends about 1.5 meters (5 feet) forward and then vents out to the open air.

Do you have any tips on this or perhaps other ideas?

I hope I explained the situation clearly. 🙂 Otherwise, feel free to ask.

Best regards,
Oliver

A picture is worth a thousand words. Such a low outlet is unusual. Hopefully, the fresh air intake is positioned higher?

In my opinion, there is no reason not to leave the space under the terrace open. The exhaust air should be able to escape freely. If you extend the duct, you will introduce an additional (although small) pressure loss, which changes the system characteristics (whether this is significant remains to be seen).

Ventilation outlets often produce (minor) noise. Therefore, the location at the terrace is not ideal in any case.

The fresh air intake is at the same level. It couldn’t really be routed any higher since it has to come out of the basement.

You’re right about the picture, so I’ve attached one. 🙂

Best regards,

Of course, the fresh air duct inside the wall can be routed higher... Isn’t that even specified in some regulation? At least 2.5 m (8 feet) above the floor or something similar?

That would certainly be interesting if there were a standard for this. Does anyone here know more?

If I were an animal, I would definitely poop in front of your fresh air intake.
