Under the Energy Performance of Buildings Directive (EPBD), EU Member States are required to put in place minimum levels of energy performance for building envelope elements when they are retrofitted or replaced. While the recast EPBD has been in place for over 5 years and while European Institutions are reviewing the directive, a new study commissioned by Glass for Europe to Ecofys, a Navigant Company, provides an inventory of the minimum requirements for window replacement in the residential sector across EU Member States. Glass for Europe, the trade association of Europe’s flat glass sector, provides its conclusions from the inventory of energy performance requirements provided in the study. The press release can be downloaded from the above mentioned website.
