Here's how to prevent 4 common cooling mistakes

During summer heatwaves, we try our best to keep homes as cool as possible. This is difficult, especially when it’s more than 30 degrees Celsius outside. And yet, there’s enough room for improvement, because many homeowners make the following 4 mistakes when trying to cool ther homes. In this blogpost, we’ll show to solve these mistakes and lower the indoor temperature more efficiently.

1) Keeping our windows open during the day

Yes, this happens frequently: people keep their windows open during a hot summer day. We understand why: when it's hot inside, we instinctively look for fresh air. And often, we open our windows for that refreshing air that cools us down.

The issue is, however, that during a heatwave, it's way hotter outside than in your home. The room temperature still is relatively cool compared to the outdoor temperature. So when you open your windows, the heat from outside enters your room, resulting in a further room temperature increase.

2) Opening our windows at night

You might currently think: “Wait, but it cools down at night. Wouldn't this be the moment to open my windows?”

Correct. But first, you should look at the indoor and outdoor temperature before opening your windows. Because often, you think it's colder outside than it really is. Especially right after sun set, we tend to open our windows when the temperature still is relatively high compared to inside.

To prevent more unnecessary heat from entering your home, you should first look at your room temperature and at the outdoor temperature. When it's really colder outside, then you can open your windows.

3) Not covering your windows

Many homes are prone to overheating, because they are not properly protected from the hot and bright sun. Many homeowners forget to close the curtains and blinds during the day. Some homes don't even have sun shading at all.

And the more sunlight falls into your room, the quicker your home warms up.

Of course, you want to enjoy some daylight, but at the same time it is precisely these sun rays that warm up your home. Therefore, it is important to partially (or better: fully) cover your windows, which will not only darken your rooms, but also reduce the temperature increase during a hot, sunny day.

Why you should cover your windows with sun shading systems

With sun shading systems like curtains, blinds, screens and roller shutters, you reduce the risk of an overheated home. Did you know that you can reduce the temperature increase by multiple degrees? With our zipscreen calculator, you can calculate the positive impact of sun shading on your home.

4) Not following the steps mentioned above when you have an air cooler

Air coolers are great: they cool down hot rooms and keep them cool. No wonder these systems are so popular. At the same time, you shouldn't forget that air coolers consume a lot of energy. Using them can be pricy.

The hotter it gets, the more energy your air cooler needs for a cooler home. If you let unnecessary heat into your home, you'll pay unneccessary energy costs.

Even with an air cooler, you should open and close windows and sun shading systems at the right times. You’ll minimize the temperature increase and save more energy while using your air cooler more efficiently.
