About IWG5


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.

IWG5 and the SET Plan

The Strategic Energy Technology (SET) Plan aims to achieve the EU’s energy and climate goals and make Europe a global leader in clean energy technologies and energy efficiency. It is made up of the SET Plan Steering Group, the European Technology and Innovation Platforms (ETIPs), the European Energy Research Alliance (EERA), the SET Plan Information System (SETIS) and Implementation Working Groups (IWGs).

The IWGs monitor and report progress to the SET Plan Information System (SETIS) on the SET Plan targets and R&I activities carried out at national and European levels. The activities and targets, published in the working groups’ Implementation Plans, are identified in cooperation with national governments and stakeholders (industry and research bodies).

For further information, please visit the official Website of the SET-Plan.

Also have a look at the Strategic Energy Technology Information System (SETIS), which is the open-access information, knowledge management and dissemination system for the SET-Plan.


IWG5 aims at delivering the Implementation Plan on energy-efficient solutions for buildings, requiring Member States to put in place measures favouring both innovation in building design and energy technologies for buildings, and the uptake of these technologies by the building sector.

Projects across Europe

IWG5 members have launched and implemented hundreds of regional, national and EU-wide projects in the field of energy efficiency in buildings. To find out more about the realization, take a look at five Exemplary Projects.

Cooperations for creating a sustainable future

Members of IWG5 are involved in the creation of various EU partnerships: Clean Energy Transition (CET), Driving Urban Transition (DUT) and Built4People (B4P)

The IWG5-CSA project, coordinated by EUREC, will support the IWG5 in delivering the implementation of the SET plan on energy-efficient solutions.

EUREC is the voice of renewable energy research in Europe, representing European Research Centres active in renewable energy. Mission. The purpose of the association is to promote and support the development of innovative technologies and human resources to enable a prompt transition to a sustainable energy system.

ECTP was launched by the construction sector in October 2004 to develop new R&D&I strategies to improve competitiveness, meet societal needs and take up environmental challenges. It gathers more than 140 Member organisations from the whole supply chain of the Built Environment.

Eurac Research is a private research centre based in Bozen-Bolzano. The researchers come from a wide variety of scientific fields and from all parts of the globe, and adress the greatest challenges facing us in the future: people need health, energy, well-functioning political and social systems and an intact environment.

WIP is a renewable energy consultancy with a long history of managing research and innovation projects and organizing leading conferences and events in the sector. Its mission is to contribute to this goal by facilitating research, innovation and market integration of renewable energy systems through collaborative efforts across all sectors of society.
