skylight at top of stairs draws cooler air up from lower floors.
Building with concrete and masonry helps keep houses in warmer climates cooler. The mass of the construction absorbs daytime heat, releasing the heat at night when temperatures are cooler. An excellent way to achieve this mass is to use insulated concrete form (ICF) construction
The air that's lower to the ground is going to be cooler. So having some awning windows down low that can capture this air will keep the house interior cooler.
Cross ventilation keeps the air from staying put and becoming stale and warm. Allowing the air to flow throughout the house keeps the interior healthier, cooler and more enjoyable.
Create a chimney effect. Again from high school science, we all know that hot air rises. So by providing a taller space surrounded by lower spaces we can create a chimney effect. The cooler air closer to the ground comes in and, as it warms up, is expelled through the top. By introducing constant air movement and by continuously replacing warm with cool air, you'll make the interior of your home more comfortable.
