Following the Climate Energy Plan of Paris aimed at reducing 75% of the greenhouse gas emissions within 2050, the « 2050 PARIS SMART CITY » project by Vincent Callebaut Architectures is a research and development work on the integration of high-rise buildings with plus-energy (BEPOS) producing by solidarity all together energy for the surrounding areas.

In order to fight against the urban heat-island phenomenon by increasing in the same time the density of the city in the long-term, this study presents 8 prototypes of mixed towers. These towers repatriate the nature in the heart of the city and integrate from their design the rules of bioclimatism and the renewable and recyclable energies in short loop through innovative systems. Turned to new social innovations, they invent first new eco-responsible ways of life to implement the quality of life of the city-dwellers in the respect of the environment.
