cover Principles nZEBWhile the Energy Performance of Buildings Directive (EPBD) requires that from 2020 all new buildings are nearly Zero-Energy Buildings (nZEBs), the proposed definition leaves a number of uncertainties, especially regarding the level of ambition for such buildings in terms of energy consumption and CO2 emissions. The aim of this study is to support the implementation of the recast EPBD by developing a sustainable, effective and a practical definition for nearly Zero-Energy Buildings.

This report strives to contribute to reaching a common understanding of nZEBs by:

  • Providing a starting point for an nZEB definition by analysing existing concepts and initiatives;
  • Outlining the main challenges and potential solutions for an nZEB definition;
  • Compiling a possible set of principles for nZEBs;
  • Applying such principles on reference buildings and assessing related effects;
  • Depicting related technological, financial and policy implications at EU level; and
  • Giving an outlook on necessary further steps towards a successful implementation of nZEBs.
