the less the better, i'd say, unless you are bound by building codes, which
talk about fire exits and 4-8% of the floorspace for ventilation. windows
are poor insulators, and expensive, compared to good walls. they can provide
solar heat on an average day, but unlike air heaters, they lose heat at night
and on cloudy days and increase the size of average and cloudy-day heat stores.

one might exit through an insulated hatch, and there are other ways
to provide ventilation.
