I'm looking for the best orientation (North-East-South-West) of a greenhouse (simplifiable as a rectangular solid).
My question is more specifically about the sun position effects (over the times of the day and over the days of the year).
With sun effect I mean both solar exposure for plants and temperature increase within the greenhouse. Anyway I think both aspects go hand-in-hand.
Thus, how can I calculate the position of the greenhouse?
PS: if can help to better focus my question, the question could also be re-arranged e.g. for house's rooms: which is the coldest/hottest room in my house?
EDIT: solar exposure's issue was solved. Now it remains how to deal with temperature gain. In short: with maximum solar exposure I will get automatically the higher temperature inside the greenhouse?
