Hello,
it’s me again with a question.
We spoke with the energy consultant, and they strongly recommended installing a central ventilation system for our house (which will only be built in early spring next year) to prevent mold. Our potential architect, however, thinks that this isn’t necessarily needed, and that ventilation in the bathroom and kitchen would be enough. A central ventilation system is not only expensive but also somewhat complicated to install and difficult to clean. Over the years, it might get very dirty and start to smell. Now I’m looking for good advice—who is right? The house will have about 180 square meters (1,940 square feet) of living space, no basement, and two full floors.
Best regards,
Katha28

Even with the summer bypass, such a system doesn’t provide a huge air exchange. If you want cooler air, it helps much more to simply open the windows.
The argument from opponents of controlled ventilation systems—that you’re not allowed to open windows—is outdated. You can always open windows, but you don’t have to when it’s cold outside.
We also don’t clean the filters weekly; I vacuum them every 2–3 weeks when I’m vacuuming anyway, and replace them every 3–4 months. That’s how it is. In summer, the ventilation system isn’t really necessary because you ventilate manually a lot. It’s simply nice to feel the breeze and airflow, and in the morning and evening you have to cool down the house anyway.
In winter, on the other hand, we hardly ventilate manually, only when cooking a lot or when guests are over.
