A quick question regarding ventilation. I built this without much thought for ventilation apart from a couple of trickle vents in the door frames. All the windows are non-opening and the interior will be plaster boarded and that’s that. I now realise I might need a couple of passive vents for through flow. The internal room size is 2.2 x 3.2 x 2m. Does anyone know of a way to calculate what size vents would be required for adequate airflow? The room will be little used and there will be no moisture generating activities inside or even much storage of anything, so it’s just to prevent mildew and stale air.
Is one ‘hit and miss’ type vent enough, combined with the door vent, or is a second one necessary too. Is it OK to position both high up on opposite walls, or is important to have one high and one low down on the opposite wall. I would rather not have one low down to reduce insect and pest entry, as well as moisture.
I was thinking 22 x 15cm Louvre Vents on the exterior and sliding vents on the inside so they can be kept closed in the winter to stop drafts with the heating on. Is this about right? Any advice on this?
