Voted European Capital of Innovation 2014, Barcelona is a vast metropolitan hub with a long tradition of industry and entrepreneurship. Barcelona City Council encourages strategic initiatives aimed at generating international collaboration, and promoting a global and forward-looking vision to businesses and public bodies, as well as scientific and technological centres.

Barcelona’s development towards a smart city began over 30 years ago when the city installed fibre optic cables to connect two municipal buildings. Currently, the City Council is using public-private partnerships to encourage innovation in areas such as transport, shopping, street lighting and environmental monitoring. Barcelona has been transformed into an urban laboratory, piloting projects and services that make the city more open, efficient and friendly.

The innovation zone, known as the 22nd District, has been chosen for Barcelona's implementation of the smart solutions within the GrowSmarter project. This multi-purpose area mixes residential, industrial and academic buildings in a lively, vibrant quarter bordering the Mediterranean Sea. Solutions being implemented in the 22nd District include introducing electric vehicles and installing charging infrastructure, refurbishing current buildings to create zero-energy blocks and installing district heating and cooling.

* Detailed information regarding the technical and financial performance will be available at a later stage.

The demonstration site in Barcelona consists of 10 refurbished buildings with an overall gross floor area of 33 110 m². The final energy demand of the site has been reduced by 2767 MWh every year thanks to the refurbishment.

According to SCIS calculations based on energy design data and the respective emission factors available (European factors – EN 15603), the primary energy savings go up to 5729 MWh/yr while the carbon dioxide (CO2) emissions reduction amounts to 1610 tonnes every year.
