The EU has been urged to ratchet up its green energy standards for buildings, with MEPs fearing they will not be strict enough.
Under the plans, the worst-performing houses and flats will be required to be renovated to energy efficiency standard F by 2030, then to E by 2033. The most energy-wasteful public and non-residential buildings will have to hit the F grade by 2027 and E by 2030.
EU energy efficiency classification runs from A to G, with G being the worst in class.
