I know the category is not quite right but could not do better.
Building a passive house involves an extra costs of 10-20% compared to a traditional house and depending on the material used. This means that it takes about 15 years to make it profitable (thanks to energy savings).
I know the figures when it comes to building. But what are the figures when it comes to a passive standard renovation?
Are there ways to make it even more profitable?
