This contest is the concrete embodiment of all statements on ecological transition: it promotes already existing solutions, integrated in buildings, districts and infrastructures.

Thanks to a worldwide communication plan, each participant – candidate, partner or jury member – will benefit from enhanced visibility among peer professionals and become a source of inspiration. In 2019, the contest generated 4 million of views at the international level.

Registration for the 2020-21 edition is now closed. You can discover the candidates via the button below and vote for your favourite projects (before May 31)!

Discover the national winners

One contest, three categories

Organised by Construction21, the Awards include a national phase, where candidates first compete within their own country, and an international phase, gathering the champions of each platform.

Originally a competition dedicated to green buildings, the Green Solutions Awards have in recent years expanded their scope to districts and infrastructures in order to take into account a wider variety of sustainable city solutions and actors.


bâtiment durable


Office buildings, housing, schools, public buildings, etc., new or renovated, and already delivered.

Quartier et ville durable


City blocks, eco-districts, urban areas, campuses, hospitals etc., the most innovative projects, totally or partially delivered.



Projects and services related to sustainable city solutions: green energy, water cycle, shared gardens, responsible mobility, circular economy, etc.
