fan or vent or both??
I am in the middle of converting an old hottub room a lean2 against the house into a sunroom/greenhouse. It has no glazing on the top (just a normal roof) but quite a bit on the south and west sides (just a bit on the east). I am going to put at least a vent on one of the gables for summer venting. I am not sure whether I need to put a fan in that location instead. The room gets quite warm in the winter but not unbearably so. Any advice would be really appreciated.
The room is about 10' X 9' X 25'
