BARCELONA
A city with 1.6 million inhabitants, and the centre of a metropolitan district with a surface area of approximately 3,200 sq km and 4.7 million inhabitants. Characterised by its high level of urban development, high population density (1,444 inhab. per sq km) and /Km2) and the existence in its hinterland of important cities with their own identities.
4th meeting “Greens in Big Cities”Vienna (Rathaus), October 26th-28th, 2007
The urban development of Barcelona since the democratic transition can be summarised in three phases:
• 1980-1987. Sporadic interventions on a small scale. Recovery of basic aspects. • 1987-1992. Infrastructural interventions and large urban areas developed as a result of the Olympic games. Structuring of the city.• From 1993 on, Barcelona as a central area of the Metropolitan District (Fòrum; 22@; Sagrera;…). Urban recuperation.

Energy efficiency
Ecopark and District Heating and CoolingThe incinerator plant was transformed into an Ecopark facility for the treatment of waste
