Humidity can be countered with exhaust fans and a good air flow. I was thinking an awning of sorts would fix things. As long as it sticks out far enough to stop "direct" summer sun from entering. Winter sun lower on the horizon could help.
Good thing I'm a surveyor by trade. That could come in handy putting the line of the building on the correct axis with the sun. The Egyptians, the Mayans and Aztecs did it with sticks and strings forever ago.
