Naturally Keeping cool indoors when it is hot outdoors is a problem. The sun beating down on our homes causes indoor temperatures to rise to uncomfortable levels.
Air conditioning provides some relief.
But the initial costs of installing an air conditioner and the electricity costs to run it can be high. In addition, conventional air conditioners use refrigerants made of chlorine compounds, suspected contributors to the depletion of the ozone layer and global warming. But there are alternatives to air conditioning. Passive cooling uses nonmechanical methods to maintain a comfortable indoor temperature. The most effective method to cool your home is to keep the heat from building up in the first place.
