ECO-City project

Sixth Framework Programme

Cofunded by the
European Commission

The project Tudela community, Spain

Area of Tudela.


The ECO-City city demonstration sites in Tudela comprise a whole integrated community approach to energy efficiency and sustainable energy supply and constitute an extension of existing policies towards a more sustainable community development.

The overall objective of the effort is to connect and balance the energy supply and demand side through an intelligent energy management system. In the future system energy supply is solely based on wind power, electricity from Photo Voltaics panels and thermal energy from passive solar and solar collectors.

The concerto project will set a reference for new standards to prevail in the community both in retrofitting, new buildings and energy supply and the initiatives will be anchored in the whole community through training and extensive dissemination.

The demonstrations in Tudela are located at two separated districts called Queiles and Lourdes.

2.7 MW biomass boilers for district heating
   and local biomass boilers
Solar collectors for domestic hot water
Photo Voltaic plants
Energy efficiency in buildings (RUE)
New ECO-dwellings of more than 12,604 m2
Refurbished ECO-dwellings - 12,514 m2
New bioclimatic office building - 1,356 m2
Potential solar cooling / heating investigated
Integration of RES and RUE
Use of bioclimatic architecture, passive solar
   heating. (Energy storage in thermal mass,
   structural solar shading etc)
100% RES supply of energy needs on yearly
Specific innovations
