EuroWindoor favours the taxonomy as it strengthened green investments by defining criteria for them. The products windows, doors and curtain walling contribute to a strong improvement of energy efficiency and therefore, climate protection in the building sector.
Unfortunately, by setting a pan-European maximum thermal transmittance value (U≤1,0 W/m²K) the present criteria for windows does not allow to factor in geographical and climatic differences to optimise resource and energy efficiency by tasking solar gains into account. As a consequence, the EU Taxonomy criteria needs to be revised to use the ‘Energy balance’ approach for transparent products like windows and curtain walling. In addition, curtain walling should have similar requirements as 'windows' since they have a large proportion of glazed area and thermally behaviour like windows.
