The Implementation Working Group on Energy Efficiency in Buildings (IWG5) works to unlock the energy savings potential of the building sector. This includes boosting the potential of existing and new buildings. IWG5 is composed of Representatives of EU and associated countries, industrial stakeholders, non-governmental organisations and research institutes.

Around 40% of the final energy consumption in Europe is due to the building sector. This shows the great potential for energy savings and the enormous importance of this sector for CO2 reduction and climate protection.
