1-liter house - has anyone had experience?

Hello,

a friend of mine is currently renovating and told me that he wants to convert his house into a [1-Liter-Haus]. What exactly does that mean and is it even possible to do something like that afterward?

Regards
Franz

Hello Franz,

unfortunately no personal experience, but acquaintances of ours are currently building a 1-liter house. The planning was quite complex, as the key is the insulation and ventilation to minimize energy loss, because only in this way can the 1-liter house system work. However, I think it is a good investment for the future, as the prices for oil, gas, and electricity are continuously rising.

Turning a conventional house into a 1-liter house is indeed possible but very labor-intensive and costly. However, the energy consumption is really very low, and in the long run, it is worth it again.

Best regards

Hello,

thank you for the answers. I had a cost estimate made for a renovation. Well, the 1-liter house is nice and all, but when I calculate my age, the renovation doesn’t bring me much anymore, the savings would probably be for my children if they kept the house.

Hello everyone,

I would like to add the following to this discussion: about one third of the total energy demand goes towards heating buildings. Many people constantly talk about the 3-liter car – but unfortunately, hardly anyone notices the enormous savings that a passive house brings.
