Lessons learned from the EPBD concerted action

The EPBD (EU Energy Performance of Buildings Directive) Concerted Action is a cooperative effort from all 27 EU Member States (MS), plus Norway and Croatia, together with the European Commission. It is running since 2004, under the Intelligent Energy programme since 2007. It aims at providing support to MS in their effort to transpose and then implement the EPBD, identifying the best solutions and practices that MS can then adopt and thus move towards harmonization throughout the EU. This report briefly describes the lessons learned, with a special highlight and focus on the issues related to ventilation and indoor air quality, as they relate to the preparation of a 2020 scenario of “nearly-zero energy buildings”.
