An active cooling system uses electricity to provide cooling for your home. An AC unit is an example of such a system. While active cooling can be highly effective, it can also cost a lot money. A passive cooling system will help to keep your home cool without the need to pay a utility bill from month to month. One of the best ways that you can use passive cooling to keep your home cool is to use shade to your advantage.
How Awnings Can Help Keep Your Home Cool
Windows can allow the sun's UV rays to pass right into your home. These rays can then heat up the interior surfaces of your home, and thus drive up the temperature in your home. The hotter your home gets, the longer and harder your AC system has to work. By placing awnings over your windows, you can provide shade that will block the sun's rays before they have a chance to enter your home. In fact, awnings can reduce heat gain by up to 77 percent and reduce your cooling costs by as much as 33 percent. Awnings can be expensive to install, but modern styles can help them to blend into the decor of your home.
Using Trees to Your Advantage
Trees can help to keep your home cool in a couple of different ways. For one, trees can screen your home from the sun's rays. This can help to keep direct sun from shining through your windows, but it will also keep the sun from heating up your roof, which can in turn heat up your home. For the best results, you should plant trees on the south and west sides of your home. While shade is important, trees also will help to keep your home cool through the process of evapotranspiration. Trees are constantly releasing water vapor into the air around your home and this vapor will in turn cool the air around your home. The cooler it is outside, the less your home will heat up.
Passive cooling strategies have been in use for centuries and can still be used to good effect today. While it is a good idea to invest in the most efficient air conditioning system that you can find, you will never cool your home as efficiently as you could if you don't use passive cooling strategies to boost the function of your AC unit.
