Hello byggahus!

During the summer, we built a storage shed/garden shed (15m2) where I will have a workbench and storage. The idea is that it should be at least frost-free, possibly a bit more than that (not decided yet).

The shed is about 3x4.70 externally, with a sloping roof. Door on the long side and window on the short side. It's not entirely clear :) If I remember correctly, the walls are 70+45 ;)

How should I think about ventilation? One near the floor and one near the ceiling? Where is the best placement? As far from the window/door as possible? Should I place it in the high part of the shed internally?

What kind of ventilation do I need, i.e., material?

Grateful for your response :)
 
One ventilation channel in each ridge (or the high side if you have a sloping roof) should probably be enough? Near the floor it will likely just create drafts and cold floors...

/K
 
Thanks for your response!

It might be silly to have one down by the feet. Is it advisable to have two up top then? Can you manage with one, or is that just being excessively cheap?

Doubling up top won't work. Just installing one is penny wise and pound foolish. Install one at the top and one at the bottom, and it will be fine. The floor won't be particularly cold because of it, and besides, you probably don't run around barefoot in the storage room during the cold part of the year, do you?
 
The bottom part can have a flap on the inside, so if it feels drafty you can just close it when you're working.
 
hmm, different opinions :)

If you place one at the bottom and one at the top, I assume they should be on opposite short sides?
Draft on the floor is probably not really a major issue, except in terms of insulation and heat capability then?
