On 9 July, two thresholds that push action in public buildings, one in the Energy Efficiency Directive (EED) and one in the Energy Performance of Buildings Directive (EPBD), will be lowered from 500m² to 250m². As the implementation of both the EED and the EPBD by Member States has proven challenging, this step towards more stringent provisions risks remaining unheeded, despite the benefits attached to these updated requirements. This underlines the need for a stronger governance architecture for the Energy Union, if it is to deliver its full potential and promises.
