So you’ve heard of ventilation and you know that it’s about bringing fresh air into a building. But do you know how it works or why it’s an important element for your home? If yes, then we’re sure you’re enjoying your home comfort thanks to your ventilator as we speak!
If not, then we would love to shine some light on why ventilation in your home is a must.
What is ventilation
As simply as we can put it, ventilation is the process of exhausting hot, humid and stale air from a building, such as your home, and replacing it with fresh, cool and dry outside air.
How does ventilation work?
As you might already know, hot air rises. This phenomenon is called the ‘stack effect’ and ventilation uses the stack effect to help exhaust hot, humid air. However, there must be a flow of cooler air into the home.
Using your air conditioning, opening windows and installing eave vents are just a few ways you can bring cooler air into your home. Even if you did none of these things, cracks between the walls, floors and roof of your home create air leaks which allows cooler air to enter and push hot air upward into your roof. This hot air is then removed from your roof by a ventilator.
Here are our top 5 reasons why ventilation is a must:
1. Ventilation will help cool down your home. During hot summer days, heat is stored in the roof and walls of your house. Without ventilation, the heat will soak down into your roof’s insulation and into your living spaces. At night, heat stored in the walls will radiate back into your home. This is especially noticeable when your home feels warmer inside than the air outside.
Using roof ventilation and whole of home ventilation will remove hot air and help to lower the temperature of your home.
2. Ventilation helps your air conditioning. On summer days, your roof can reach temperatures of up to 70oC . Imagine the effort it would take for your air conditioning to pump cool air through this hot roof space and into your living spaces!
Not only can this make your air con inefficient and costly to run, but it takes longer for it to cool your home. Using roof ventilation to reduce the temperature in your roof cavity will help your air con to efficiently cool your home without losing cold air to the hot roof space.
3. Ventilation helps you get a better night’s sleep. If you keep your air con on while you sleep, you might notice that the air becomes dry which can irritate your throat. Ventilation removes the need to keep your air con on at night as it cools your home with cooler, fresh outside air.
As a bonus, because ventilation continues to remove the heat load in your house during the night, your home is already cooler in the morning so your air con has less work to do to cool your home when you wake up.
4. Ventilation removes damp air. In cooler months, we tend to keep our homes closed up to keep in warm air. But this means that hot, humid air from cooking, showering and using the laundry rises up into the roof space.
In colder months, due points are lower and your roof space becomes cold meaning it can’t hold humid air. So, when humid air rises into the roof cavity and meets the cold surface of your roof, it condenses looking something like this:
This will eventually cause problems like mould, mildew and structural damage to your home. This not only poses a threat to your health, but can be costly to fix.
Using ventilation will exhaust hot, humid air and prevent condensation and mould, protecting your health and your home.
5. Ventilation can help warm your home. During winter, our homes tend to hold cold air even when it feels warmer outside. A mechanical ventilator can be turned on during the day when the temperature is warmer to bring in this warmer air and help raise the temperature in your home.
All in all, ventilation is about keeping your home at a moderate temperature, without it being too hot or too cold, to improve your comfort level.
Ventilation creates increased comfort, less air conditioner usage, lowers energy bills, a better night’s sleep, mould & mildew prevention and overall, increased wellbeing for you and your family.
And that is why ventilation should be a must in your home.
