For hot humid climate, it is essential to have air flow to reduce the effects of humidity, so one should build stretched horizontally with plentiful operable openings for cooling airflow. Use overhangs and landscaping for shading. Keep surfaces hard and reflective to dissipate heat. For hot dry climate, often nights get quite chilly, so one must use building materials with great 'thermal mass' to trap and hold the sun's heat into the night, materials like concrete, stone, tile, etc. Here, too, shading by overhangs or landscaping is essential, but you might need barriers against unwanted strong winds.
