Cooling System
Without too much reliance on a central cooling system or an air conditioning unit, there are so many ways you can keep cool in hot temperatures. There is, of course, a multitude of manual ways such as draping a wet sheet over the window, or putting frozen water bottles in front of a fan. But there are design features that you can add that will work as a natural convection. The basis for one of these is ‘hot air rises.’ But building vents on your south (hottest) and north (coolest) side of the house (North America) you can create this flow of air. Air molecules expand when hot; therefore, a larger vent will be needed on the South side to get the greatest efficiency of this system. In turn, a smaller vent will be necessary on the coolest (usually North) side of the structure.
