The first competing case studies displaying your solutions, for a building, a district or an infrastructure will benefit from the extensive media cover of the beginning of the competition. Submit your application before June 1st, 2017!

Each winner will receive a professional video describing the project that will be broadly shared on the web.

Who can compete ?

The competition distinguishes buildings, eco-districts and sustainable infrastructures contributing to the fight against climate change. They can be referenced by any stakeholder in the operation: owner, architect, engineer, industrial, developer, construction company, operator or even buildings’ users.

As an industrial, you can complete an existing case study with your solution implemented in this building or neighborhood.
