Construction21 International Community

Construction21 network is currently managed by an international non-profit association, Construction21 AISBL, established in April 2013. The association is constituted of national chapters, which manage the Construction21 portals in each country. The association gradually welcomes new partners opening Construction21 platforms in new countries.

The Construction21 AISBL president is Christian Brodhag, Construction21 French chapter president.

From local to global

Construction21 has developed an original approach, combining local to global. Construction21 is first considered as a national portal, where users share information and experiences with their peers, in their language.

Construction21 is also an international online network, offering to professionals an access to innovations issued from the whole world.

The current partners members of Construction21 AISBL are:

Association Construction21 France         Chaire UNESCO Cycle de vie et changement climatique (ESCI-UPF) - Barcelone

The Association Construction21 France was created at the end of the European project, in 2013. The association is gathering 100 organisations, all deeply committed to sustainable construction challenges. 

  The UNESCO Chair in Life Cycle and Climate Change is an innovative research group, internationally well-known, pioneer in developing and implementing the methodology of Life Cycle Assessment (LCA).

IEE-Intelligent Energy for Europe


Construction21 was originally created, thanks to European funding, by a consortium of nine partners (IFPEB, ESCI, UCV, ANCE, DGNB, PE, RoGBC, VGTU and CIRIDD) wishing to accelerate the environmental transition of the building market. The project, winner of the "Intelligent Energy for Europe" call for proposals, received significant support from the European Union during the first two years (May 2011-May 2013). Read more

Construction21 is also closely linked to BUILD UP, the European Commission portal on energy efficiency in buildings, which publishes all the case studies and news from the international Construction21 platform.
