Without a doubt our attics are the hottest places in our homes. At times during the summer the temperatures could reach as high as 200 degrees or more. No matter what steps you take to cool your home with put the adequate ventilation your attics it could be a struggle to keep your homes cool in the summer and warm in the winter. Our homes in which we live are alive and breathing much like we do. In this article we will look at what I mean when I say our homes are living and breathing and explain what natural ventilation is and how it will help you save energy in a big way.
In science we have always been taught that hot air rises. It is this principle that makes natural ventilation work. Most of the heat that is generated in our attics hangs around in our attics. This is why our attics are so hot. If there is no place for the hot air to escape our houses will not start that breathing process. What I mean by this process is hot air out and fresh air in. Without this process it is difficult to efficiently cool our homes. The ac unit in our home does more than just cool our homes. The ac unit also circulates air throughout our home. That is the reason we have air returns and filters on our ac units. If you turn your ac unit on and go to a closed room and feel at the bottom of the door you will feel air being pulled from the room towards your fresh air return on your unit. The same principle applies when your ac unit pulls hot air down from your attic through holes light sockets and ceiling fans as well as other small cracks in and around your ceilings. This is the main reason why we need our attics to be cooler.
There are several ways we can vent our attics and keep them cooler. WE will begin to take a look at several different types of vents that are natural vents and cost you no money at all to operate. These vents work from the natural movement of hot and cold air. There are many types of vents that do operate form electricity that will do a really great job of venting your attic. But the object here is to save money. You can use one of the following methods and your attic will vent. The more you use the better because all these types of vents we will look at work great together.
- · Continuous ridge vents are located and installed at the peaks of your roofs. They are designed to let the hot air escape through the openings located at the very top of your roofs. There will be about a 2″ gap on each side of your ridge and it will run the total length of your building. This will allow hot air to escape out the top of your attics.
- · Gable vents are located at the ends of your attics at the top of your gable ends. These vents will also allow hot air to escape out of your attics.
- · Whirly birds are vents that are installed close to the top of your roof. These are installed on the outside of your roofs. When the wind blows the turbines are turned and it helps exhaust the hot air from you attic.
- · Soffit vents are located at the bottom of your roofs underneath the soffits. They are usually installed every 4′ around your house. These small but effective vents are very important because when hot air leaves your attic fresh air is pulled into your attic through these vents. This is where the breathing aspect for your home comes from.
If you install these vents in your home your attics will cools off several degrees and you homes will be easier to cool and therefore saving you money. Not to mention after these are installed it cost you no money for them to operate. You will be cooling our attics with natural ventilation.
