sustainable structural design
I am looking for sustainable design ideas/blueprints to bulild a house but i want to make sure that I minimize the need for air conditioning in hot/humid towns.
With regards to the structure I keep noticing that hot countries tend to have houses with flat roof where as cold/rainy countries tend to have a pointed "^" roof. Please correct me if I am wrong but I assume pointed roofs lose less heat because of the reduced surface area. Hence the hot countries need flat roof to disipate more heat.
I know that SIPs are a good insulator but I am worried about the ventelation. Another worry i have is the strength of a sips house, can you easily have 2 floors (i.e. a ground floor and a first floor)
If any of you have seen house designs that are amazing for the hot/humid climate please help.
