ᐅ ERV Supply and Exhaust Air for an Extension

Next year, we plan to build our carport, which will gradually be converted into a garage—partially enclosed with side walls, etc. The carport will be built where the current outdoor air intake and exhaust outlet are located. I am now wondering what needs to be considered?

Exhaust outlet:
The warm exhaust air from the house should definitely not be vented into the carport, as the warm air could condense there. I could still vent it with little effort over the roof of the eventual carport.

Fresh air intake:
I could extend it about 5–6 meters (16–20 feet) under the roof of the future carport and insulate it to bring somewhat warmer outdoor air into the house during winter or to improve heat recovery for the mechanical ventilation with heat recovery system (especially once the carport is fully enclosed as a garage).

Or is all this unnecessary and too much effort for little benefit? In that case, I would simply route the outdoor air intake and exhaust outlet over the roof of the future carport and vent them directly to the outside.

I would lead it outdoors.

As long as the carport is not fully enclosed, you can simply leave the exhaust air as it is. Most of the moisture already condenses in the heat exchanger.
However, I would also direct the fresh air intake to the outside via the shortest possible route.
