I think the big bonus in time that I get comes from being in a warm spot in Maine and being up on the South facing hillside that descends a long ways down to the river that separates southern Maine from NH....LOTS of room for the cold air to drop away from me.
This is an important point to keep in mind when looking for property and locating features on the homestead. A feature not mentioned is not only dose the cold air fall away but if there is a source of warmth such as a body of
water the air warmed will rise up the slope. that river of warmth will provide a warmer micro climate. For example we had a garden alongside a spring that flowed down into the bay below. Not only did cold air flow away from the garden but warm air would flow up under the branches of the fir
trees and onto the garden.
So applying it to wofati design give consideration to cold air flowing away from entrances and catching rising warm air that may be rising. Note the difference under the overhang and the more distent outdore temperature.
