There’s a standard in the EU called Building Energy Rating (BER) which is disclosed when a house is sold. It’s a scale that runs from A-G, with A rating being the most energy efficient.

Anecdotally it doesnt seem to have a huge impact on the asking price.

There is a strong correlation between BER and the age of the house. In Denmark the majority of houses are in category D. Almost every house built after 2007 is >D and EVERYTHING that is built after 2011 is A or B, with a large majority in A.

My house is from 1935 and the statistics tell me that it is practically impossible for me to get the house above C. I think that it is theoretically possible but the required investment will be so big that it makes more economic sense to tear the house down and build it with modern materials and techniques.
