More efficient lighting

Barcelona’s public lighting only accounts for roughly 20 % of the municipal service's total energy consumption. It has over 146,000 light points which present a high disparity of criteria and models, resulting from years of various urban-planning renovations and isolated maintenance works.

Today’s management aims to generate a night-time image of the city that standardises aesthetic and functional criteria by incorporating LED technology into light points while reducing energy consumption.

Centralised heating and cooling networks

Barcelona has two centralised urban air-conditioning networks: the east network, covering the Fòrum-22@ area and the west network, covering the Zona Franca and the La Marina del Prat Vermell neighbourhood. The networks supply buildings with hot and cold water for central heating and air-conditioning and sanitary hot water.

Centralisation in production enables better energy efficiency in relation to individual solutions with boilers and air-conditioning equipment. Buildings that are to be supplied are connected to the supply station through a network of pipes conveying hot or cold water produced in the station. The generation is carried out by making the most of the residual energy resources, such as those from the El Besòs revaluation plant, or by exploiting the residual cold generated in the regasification process of liquefied natural gas in Barcelona Port.

The two existing heating and cooling networks are currently over 24 km long. Between them, they supply thermal energy totalling 105 GWh/year and the goal is to continue expanding them.

The networks are managed by joint ventures that Barcelona City Council takes part in. If you would like to know more:
