Maximising energy savings from glazing
Glass for Europe has released a publication on the Energy Performance of Building Directive, maximising energy savings from glazing. The purpose of this brochure is to inform all stakeholders working on energy performance in buildings about the EU legislative framework and how its robust implementation across European countries could help tap into the energy savings potential of advanced glazing.
According to several studies, the average energy performance of windows in the EU building stock is extraordinarily poor. The average thermal transmittance value of 3.4 Uw is that of a mix of products from the late 1960s and 1970s, when incomparably better performance products are readily available in Europe.
While window retrofitting and performance have been overlooked for many decades, Glass for Europe is keen to make sure that future national building codes become window and glazing-proof.
The revised Energy Performance of Buildings directive (EPBD) must be implemented in all EU Member States in a little less than a year time. According to Glass for Europe, it is essential for proper implementation that its provisions are well understood and that national stakeholders understand the specifications of windows so that revised national legislations can be designed in a such a way as to maximise both energy savings and the uptake of high performance glazing. To that end, this publication from Glass for Europe includes implementation recommendations.
