We learned early on that insulation in the roof/ceiling, overhangs on the porch, and tree shade don't matter much if your windows are wide open and it's 95 degrees outside. We open the windows at night, close them at first sight of the sun, and use air conditioners as necessary to remove humidity and cool. It works well for us.

What is the best way to avoid that?

There's an interesting piece in today's BP concerning the woes of building your own home. Pretty much every expat we know who has built their own home had a fair (to great) amount of problems with the building process. A Thai friend of ours who lived in Seattle for 30+ years came over a few years back to build his own home. I followed the process with interest, thinking I might learn a few tricks of how a Thai deals with building problems here. To my surprise, my friend went through 3 different contractors and suffered more problems than most anyone else we know. He finally finished his home, but after much pain and agony in dealing with shoddy construction.
The author's bottom line in dealing with Thai construction is: either buy a ready-built home or build it yourself (as in 'build it YOURSELF).

Insulation will help with aircon, building in a heat sink works well too. I have designed my house and it will be insulated well, have a heat sink and big overhang to keep the sun out. I will look for the book on heatsink design. it is a book that a man wrote after the patent expired on his designs
