Article 8 requires that, when buildings undergo major renovation, their energy performance is upgraded in order to meet the minimum energy performance requirements set in Article 5, in so far as that is technically, functionally and economically feasible. Article 8(2) requires that, where a Member State applies a building element approach (rather than whole-building), it ensures that the elements achieve the minimum energy performance requirements for those elements. Article 8(7) requires Member States to phase out fossil-fuel boilers from buildings as soon as possible and at the latest by 1 January 2040.
