Although your first idea for cooling might be a/c, there are numerous options that offer cooling with less energy usage. A combination of proper insulation, energy-efficient windows and doors, daylighting, shading, and ventilation will normally keep homes cool with a minimum of energy usage in all but the hottest environments. Although ventilation must be avoided in hot, damp environments, other approaches can significantly alleviate the need to put cooling. Before choosing a cooling system, you might want to familiarize yourself with the concepts of heating and cooling.
VENTILATION FOR COOLING
Whether counting on natural ventilation or forcing air through your home with fans, ventilation is the most energy-efficient method to cool your home.
FANS FOR COOLING
Well-placed fans are sufficient to keep convenience throughout the cooling season in lots of parts of the nation.
In many climates, you can use a whole-house fan to fulfill all or most of you to your house cooling needs.
For homes in dry environments, evaporative cooling or "overload cooling" provides an experience like cooling, but with much lower energy use.
Ac system alternatives include space a/c unit, ductless mini-split a/c unit, and central air. Many a/c units operate at less than their maximum effectiveness, presenting energy-saving chances. New air conditioning devices are much more effective than earlier models. Dehumidifying heat pipelines can help an a/c unit eliminate humidity and more effectively cool the air.
RADIANT AIR CONDITIONING
Radiant cooling cools a floor or ceiling by soaking up the heat radiated from the remainder of the space and can be proper in arid environments but troublesome elsewhere.
