New EU energy rules require 20,000 euro upgrade to older homes

The average cost of upgrading the energy performance of an older apartment will set homeowners back between 15,000 to 20,000 euros, experts estimate, as the European Commission puts the final touches to directives targeting the green renovation of homes.

In a bid to meet tougher energy rules, Greek home owners will be hit with between 15 to 20 euros per square meter for a 100 square meter apartment, according to figures cited by daily Kathimerini.
