Brussels, 28/06/2007 (Agence Europe) - On Thursday, the European Commission launched court proceedings against Greece for failure to notify its implementing measures on the Energy Performance of Buildings Directive. Reasoned opinions - the last step before a formal complaint to the Court of Justice is lodged - were sent to Estonia and Poland for failure to notify the necessary measures. Directive 2002/91/EC, which should have been implemented by 4 January 2006, requires Member States to establish minimum energy performance standards and energy performance certification schemes for buildings, as well as ensuring that heating and air conditioning installations are regularly inspected to enable performance improvements.
