We have plenty of storage spaces in a large utility building, but almost nowhere to store things moisture-proof.
If I want to build a "dry" storage room inside the utility building, what should I consider?
What is required in terms of heating, insulation, ventilation, etc.?
Low operating cost is prioritized.

What type of things need to be stored "moisture-proof"? We have/had various "summer cottages" with various sheds/utility buildings that have always been unheated in the winter, and have stored various "normal" things there without having had any moisture problems.magnusj said:
Yes, I've stored similar items without any problem in cold summer cottages. I have loads of clothes, books, and more without any issues. I might not store valuable antiques, though. Whether my cottages have been less humid than your utility building, I'll leave unsaid. Maybe they have.magnusj said:
And so Alfredo lives in Västernorrland, which, for Sweden, remains relatively dry.
But moisture-proof, all that's needed is heating and possibly a bit of ventilation; technically, ventilation isn't necessary unless you add moisture, but it might otherwise lead to a slightly stale smell.
Therefore, you need to build a room that you insulate thoroughly; the more insulation, the less heat it will require. Then you heat it with, for example, a direct-acting electric radiator. The very best would be a thermostat that controls based on RH rather than temperature, but such probably doesn't exist (in that case, you'd have to build one yourself). The next best is likely to have the thermostat set to (at least) 15 degrees during the summer months and 10 degrees during autumn, winter, and spring.
Consider that you need about 10 degrees above the outdoor temperature to be safe. In spring and summer, the humidity is not as high, so you can probably manage almost entirely without heating or just a little bit.
