4th meeting “Greens in Big Cities”Vienna (Rathaus), October 26th-28th, 2007

URBAN PLANNING PROCESSESIN BARCELONA


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.


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.


Urban transformation of the north-eastsector of the city:

Forum 2004 district

22@ business district

Sant Andreu – Sagrera Sector

Plaza de Les Glòries


Forum 2004 district

Integration of important environmentalInfrastructures into a fully-developedseafront


• This event took place in a renewable urban area

• What was there:

– A thermal power station

– A water-treatment plant

– An incineration plant

Obsolete infrastructures from an environmental point of view


• What we have done: – Substitute the thermal power station for a

combined heat & power plant (CHP Plant)

– Improve environmental quality in the water-treatment Plant and the incineration Plant


• The urban renewal project

– Converting an industrial, marginal area into a new central area of services and leisure (convention centre, cultural centre, hotels, and a large square of 14 hectares) integrating the environmental infrastructures into the city

– Developing urban fabric from obsolete environmental facilities and infrastructures


The Urban Solar Power Station

Installation of 10,700 m2 of photovoltaic modules = 1.3 Mwp installed power

6,700 m2 used to create a structure offering areas of shade on the Forum Esplanade; 4,000 m2 located on a large photovoltaic pergola


Environmental values• Use of renewable energy sources

• Energy obtained = electricity consumption for about 1,000 homes

• Outstanding reduction of the polluting atmospheric emissions (about 440 tonnes of CO2/year)


Energy efficiency

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

District Heating and Cooling is based on the use of the steam generated

The project involved a 3,5 km network: it will supply hot and cold water to the buildings in and around the area of the Forum 2004


Energy efficiency

•Energy efficiency improvement: 32% reduction in primary energy consumption; reduction in the consumption of non-renewable resources (= 1,850 tonnes of oil per year)

•Reduction in atmospheric pollution: reduction of about 5,000 tonnes of CO2/year

Environmental values



New urban model for developinga dense, compact city



Urban complexity and the co-existence of non-pollutant industrial, technological, residential uses, with offices, hotels, small businesses, community services, etc.

• Renovated economic activity. 200 hectares.• Construction of 4,000 council houses.• 75,000 sq m of new green areas.• 145,000 sq m of land for community services.• 100,000 – 130,000 jobs.



22@ Infrastructures Plan

Incorporation as a basic objective of the urban planning.

• A model, no exception• Affecting public areas and private community areas, determining aspects of the land and subsoil



Plans for infrastructure and services networks:

Hydraulic system: underground waters and drainage Selective waste collection and recycling of wasteUse and production of energy, cold and heat processes Public areas and urban fittings Accessibility, mobility and public transport Telematic grid and other services



Poble Nou Industrial Heritage Plan

Conservation and recovery of buildings of great architectural, historic and social interest for community use or special residential uses



Urban renovation process revolving around the project of a large intermodal railway station



Articulated from north to south surrounding a large lineal park along a length of 3.5 km, covering the railway line and linking up two neighbouring districts that had always been separated


Plaza de Les Glòries

A new cultural and administrative centre

• Dismantling of the raised ring road structure• New intermodal group public transport systems centre• Enlarging of green areas


RENOVATION OF INDUSTRIAL AREAS

•Verneda Industrial – Can Estadella

A sector of 650,000 sq m of land. The 30% for community services and green areas. About 50% of social housing


RENOVATION OF INDUSTRIAL AREAS

• New district of La Marina – Prat Vermell A sector of 750,000 sq m; 11,000 new homesUnderground water network and drainage systemPneumatic waste collection stationCentralised hot-cold conditioning systemChannelling of servicesAccessibility, mobility and public transport


USING RESIDUAL COLD FROM THE REGASSING PLANT IN BARCELONA PORT

• Reduction in the consumption of primary energy and CO2

emissions• Reduction in the environmental impact on the seafront• Reduction of 1% in electricity consumption, 200 GWh/year

Construction of a new plant for the generation of heat and cold. Installation of the distribution network.


Area surrounding the air-conditioning project

USE OF RESIDUAL COLD FROM THE REGASSING PLANT IN BARCELONA PORT


WIND TURBINES IN BARCELONA PORT

Three wind turbines. Total power of 6 MW. Electrical production of 7,600 MWh/year. Symbolising a renewable Port
