How can ventilation help cool your home?

Create a fresh breeze with positive pressure systems

Positive pressure systems help over summer by pulling fresh cool filtered air into your home without the bugs, noise and pollen. This air is best pulled from outside your roof cavity so make sure to add a flexi-air source to your system, so the most comfortable air is used to force out the old stale air.

Keep the cold inside with heat recovery systems

Heat recovery systems provide all the benefits of fresh air with minimal temperature change, perfect for pairing with an existing air conditioning system. When the incoming and outgoing air passes inside of the heat recovery core, the temperature is shared, so you can retain fresh cool air without an enormous power bill.

Why is my home overheating?

Have you been wondering why your home is so hot over summer? Chances are your overheating problem is caused by a combination of poor shading, orientation of your home, and a lack of ventilation. 

New homes are often airtight and energy efficient goldfish bowls. They are great at keeping heat in during winter, but poor at letting it out over summer. Without a way to escape, the hot air only gets hotter, turning your home into a furnace.

Ventilation can help cool your home by swapping that hot stale air with fresh cool air, reducing your overheating problem and cooling your home without using AC.

But why use ventilation and not just a window?

Why aren't windows cooling my home: lifestyle

Windows (and natural ventilation) often aren't enough to properly ventilate your home. Windows use natural ventilation or wind to blow air through your home. The air goes in through a window on one side, and out a window on the other.

However, we often either don't want to or forget to open windows, especially at night.* During an NZ summer, concerns over security, noise, or even just keeping the bugs out are all very valid reasons to not open your windows, but it comes at a cost of letting hot humid air build up indoors.

*Which is unfortunate, because the most effective time to have them open is at night.

Why aren't windows cooling my home: structure

Even if do you change your lifestyle to take advantage of natural ventilation, most modern homes are not designed to take advantage of it anyway.

Building code restricts most second storey windows from opening more than 10cm (NZBC F4/AS1), limiting how easily air can flow from one side of a building to another. That coupled with fire walls, higher density construction, or just closed doors, result in fewer air pathways in general.

These important safety improvements interfere with how easily air can pass through your home which massively reduces the effectiveness of natural ventilation. This means that all the hot air just sits inside your home and continues to get hotter, unless you have some other way to get rid of it.

What is free cooling, and how can it help?

Free cooling is simply the process of using the colder outdoor night time air to 'flush' all of the warmer air out of your home. This is common practice in most commercial and industrial spaces, but homes are well suited to take advantage of it too. 

By using a ventilation system and free cooling you can enjoy a fresh cool home and a respite from all those sleepless nights, without a massive power bill.
