The Building Directive sets overall requirements to the system, the house, and individual requirements to the individual components. A large inclusion of system thinking in both the voluntary instruments and the Ecodesign Directive could be encouraged and between different regulations and voluntary instruments. Hence if it works for Ecolabels it is likely also to work as requirements in the Ecodesign Directive's IM. In an adapted, less ambitious, version, as the synergies between the voluntary instruments and the minimum requirements should be preserved. It is important to emphasise the different scales of setting requirement in the voluntary instruments targeting a limited section of products compared to setting requirements to all products produced or imported in the EU.
