DISTRICT HEATING - FORUM - Barcelona - Spain

The universal forum of cultures

The forum initiated one of the largest urban redevelopment sites in Europe. Built according to sustainability criteria, it will hand back to Barcelona a fully renovated district as well as a new residential, financial and cultural area. The redevelopment area covers about 14 hectares between Besos and the sea. The construction of new blocks of flats, offices, hotels, shopping centres and a university campus link this district to the centre of Barcelona.

INPAL Energia supplied the first Spanish network with 4 kilometres of Polyuretub 130 pre-insulated pipes. The pipes and accessories were buried by Aïgues de Barcelona and Acsa (Agbar Construction S.A.). The owner, Districlima, will operate the network for 25 years. Districlima consists of Elyo Iberica, Agbar, Tersa, Idae and Icaen.
