97% of buildings in the EU need to be upgraded

Share this Post:

BPIE undertook a detailed analysis of EPC data and finds that 97,5% of the building stock, currently not in the A class, should therefore be upgraded, making the figure of 75% of the European building stock being ‘energy inefficient’  obselete.


The gap between the two figures can be explained by the general assumption that all buildings built before 1990 (and any EU building regulations) are inefficient and all built after are efficient, determining the efficiency level of the EU building stock based on its age. EPCs are currently the only available EU-wide source of information on the energy performance of the building stock.

This factsheet brings forward recommendations to ensure that the revised buildings Directive (EPBD) provides clear and effective requirements and support tools for the renovation of the building stock.
