Orienting Your House: Architect François Lévy
Ideally, for (hot) climates, homes should have more exterior wall facing north (where there is infrequent direct sunlight, except early in the morning or late afternoons in midsummer), or south (where the high summer sun is easy to control with a roof overhang). Too much eastern and western exposure and the house will quickly heat up in summer, costing more to cool, or being uncomfortable, or both.
