Exemplary role of public authorities
Buildings with a useful total built-up area (TBA) over 500 square metres and which are occupied by a public body or frequently visited by citizens are subject to an obligatory energy efficiency audit and have to provide an energy performance certificate (art. 17 in conjunction with art. 19 EEA).
In addition, as of 9 July 2015, the TBA of buildings subject to obligatory certification will be reduced to 250 square metres (art. 17 in conjunction with art. 19 EEA).
