]Zero emissions Project

The Institute of Advanced Archi-tecture of Catalonia is involved in a research project to transform the city of Barcelona in a Zero Emission city. The barrio of Camp del’Arpa, located in the northeast part of the territory, was analysed using the Ecotect tool, and the results will be used in the future proposal for the region.
