We expect numerous applications for innovative buildings, districts and infrastructures. Discover the candidates of 2017 and get inspired by their solutions for your future projects!

Exceptional visibility across the world

On the web

Competing realisations benefit from a massive media cover, through an intense communication campaign on all 12 Construction21 platforms and on social media.

Also, each winner will be offered a video describing their project and this video will be broadly shared on the web.

Through the mobilized partners

The competition is supported by institutional partners, media organisations and trade fairs of the sector, but also by many professional organisations who will mobilise their members, in each country and at an international scale.

Internationally, the Green Solutions Awards is part of the actions of the Global Alliance for Buildings & Construction. The contest also benefits of supports of renown international NGOs such as Arnold Schwarzenegger’s R20, ICLEI, World Climate. See the 2016 winners.

Manifestations will take place at every step of the contest, offering many opportunities to promote competing realisations and the professionals behind them : launch at MIPIM, press conference announcing national winners in September, events on World Efficiency and Batimat in Paris, Awards ceremony at the COP23 in Bonn, in November.
