Buildings account for roughly 40% of the European Union's energy use, and most are heated by fossil fuels. The proposed new rules could require millions of buildings to be upgraded using methods such as insulation or efficient heating systems.
"Soaring energy prices have put the focus on energy efficiency and energy saving measures. Improving the performance of Europe’s buildings will reduce bills and our dependence on energy imports," said Ciaran Cuffe, lead lawmaker on the rules. Out of 637 lawmakers present, 343 were in favour of the new rules which would require all EU buildings with a G energy performance certificate - representing the worst-performing 15% per country - and the next-worst F rating to be renovated this decade.
