Procaccini, Giulia (author), Prieto, Alejandro (author), Knaack, U. (author), Monticelli, Carol (author), Konstantinou, T. (author)The European building stock demands urgent renovation due to the age of the buildings, their expected lifetime, and their excessive energy consumption, which accounts for more than a third of the EU’s total emissions.

Haase, Matthias (author), Konstantinou, T. (author)Roughly 97% of the European Union (EU) building stock is not considered energy efficient, and 75–85% of it will still be in use in 2050 (Artola et al., Boosting building renovation: What potential and value for Europe? 2016). Residential buildings account for around two thirds of final energy consumption in European buildings. The rate at...conference paper 2024
