Energy renovation

Take care of your indoor climate when renovating

Energy renovation has become popular. People have generally become more environmentally conscious and want to emit less CO2. At the same time, gas and electricity prices are rising, so many people want to keep costs down by, for example, adding insulation. The purpose of energy renovation is to retain heat, which typically means insulating the roof, walls, windows and floors.

If the insulation is done correctly, it will also improve your indoor climate, but if it is not, it can have major consequences for the indoor climate. It can cause problems with too much moisture in your home, which can result in mould. And mould is an uninvited guest in our homes, often causing unsightly black stains on walls, ceilings and floors and health problems such as headaches, fatigue, dry mucous membranes, asthma and allergies.

And what's worse: You could have problems with dry rot, which is a fungus that decomposes wood and, in the worst case, can also spread through masonry. We therefore recommend that you consult with an energy renovation expert before starting the renovation.

Ventilation is key in all types of renovation

It's always necessary to consider the indoor climate when renovating - and this applies to all types of renovation. It is essential that your home is properly ventilated. Ventilation replaces polluted, moist air with fresh air and is essential for a healthy indoor climate, especially in rooms like bathrooms and kitchens where moisture levels are highest.

If you are replacing your doors and windows in your home, consider choosing those with fresh air vents. Even though many of us know that we should air out several times a day, it's not always easy to remember. That's why it's a good idea to have fresh air vents in your windows, because the windows themselves will allow fresh air to flow into your home.

However, it's not enough to just use fresh air vents - the recommendation is still to ventilate with draughts 2-3 times a day for 5-10 minutes. Fresh air vents also lead to heat loss, so a good alternative is a ventilation system with heat recovery.

Solution

Invest in a ventilation system when renovating

There are many things you can choose to prioritise when renovating your home - but according to several professionals and experts from Realdania's Healthy Homes project, a ventilation system is one of the solutions that improves the indoor climate the most.

That's why we recommend the DUKA One, a heat recovery ventilation system that ventilates your home 24 hours a day. For 70 seconds, the system extracts polluted, moist air and stores heat in the unit's ceramic core. After 70 seconds, the system's motor reverses and blows in fresh air that is heated by the ceramic core. This constantly changes the air, ventilating away particles and moisture and saving you money on your heating bills as the heat in your home is recycled. We install the DUKA One directly in the outer wall, and the system can be installed wherever you need it.
