Keeping cool indoors when it is hot outdoors is an acute problem. The sun beating down on the 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. Conventional air conditioners use refrigerants made of chlorine compounds, suspected contributors to the depletion of the ozone layer and global warming. There are many alternatives to air conditioning. If people use some common sense suggestions and low-cost retrofit options to keep cool and save electricity.
Natural way for cooling
An alternative way to maintain a cool house or reduce air-conditioning use is natural cooling. Natural cooling uses non-mechanical methods to maintain a comfortable indoor temperature. The most effective method to cool home is to keep the heat from building up in the first place. The primary source of heat buildup is sunlight absorbed by the house through the roof, walls, and windows. Secondary sources are heat-generating appliances in the home and air leakage. Specific methods to prevent heat gain include reflecting heat from sunlight from the house, blocking the heat, removing built-up heat and reducing or eliminating heat-generating sources in the home.
Other ways to keep home naturally
Using of natural strategies can help to keep the house cool. Even if some one use air conditioning, many of these strategies, particularly reflecting heat and shading will help to reduce the energy costs of running an air conditioner and keep the house naturally cool. However, adopting all of these strategies may not be enough. Sometimes the need of supplement natural cooling with mechanical devices may require. Fans and evaporative coolers can supplement the cooling strategies and cost less to install and run than air conditioners. Ceiling fans can also make the house cooler. Their effect is equivalent to lowering the air temperature by about 4° F. Evaporative coolers use about one-fourth the energy of conventional air conditioners but are effective only in dry climates. There are many ways through which we can help to keep our home cool they are reflecting heat away, applying a reflecting coating in the roof, white exterior wall absorbs less heat, two main types of coatings in the window including sun control films and combination films, two excellent methods to block heat are insulation and shading, landscaping is a natural and beautiful way to shade the home and block the sun.
