This international competition of sustainable buildings, districts and infrastructures is supported by ADEME and the Global Alliance for Buildings & Construction. It aims to widely disseminate innovation in order to accelerate transition to a more sustainable world. The winners will be announced in Bonn, Germany, in November, during the Conference of the Parties on climate change (COP23).

Main steps of the 2017 edition

Apply by simply publishing a case study

The contest is open to all types of buildings, districts or infrastructures, new or renovated. Only one requirement: competing realisations must be delivered before June 30, 2017.

To enter the contest, participants only need to publish a case study before June 1st, 2017 in one of Construction21 databases. It will be moderated by one of the Construction21 national team, then translated to become visible in English, French, Italian, Spanish and Chinese over the whole network. If there’s not yet any national Construction platform available, practitioners may publish their case study on www.construction21.org in English, French or Spanish.

A jury of experts and an online vote will determine the winners in each country, and then the international winners.
