Zaragoza, Spain

Zaragoza is together with Lyon one of the 2 cities involved in the RENAISSANCE project, part of the Concerto Initiative. The project involves El Picarral, an existing community in need of building refurbishment and urban re-generation, and Valdespartera, a new community. Both are linked by the integrated political commitment of all actors and a common set of performance criteria.


The CONCERTO approach

The common objective involves a bioclimatic approach of social housings, with high energy-efficiency criteria, in order to have an impact on the whole urban fabric. Socio-economics research should enable us to better understand the perception and the social acceptance linked to innovative techniques and the habits to have.

The Sustainable Town Planning Centre main objective is to advocate and promote energy policy. It organises as well exhibitions as seminars and provide the inhabitants with training sessions. It enables also to advise them regarding their energy consumption thanks to the monitoring of a significant share of the constructed or retrofitted dwellings under the project. The experience of the “Colegio Domingo” (Public School) refurbishment is disseminated through specific trainings.


Use of Renewable Energy Sources

•    Photovoltaics
•    Solar Thermal
•    Thermal Use of Biomass

Low Carbon Technologies

•    Insulation
•    Glazing, Windows


Highlights

Researchers are setting-up an innovative model of ESCO (Energy Service COmpagny) that may become an exemplary model all over Europe.

RES in the Zaragoza RENAISSANCE community supplies over 40% of the total energy demand. Poly-generation involves a small scale 50kW bio-mass system providing power, heating and cooling integrated with a solar thermal based cooling system included in the Valdespartera interpretation centre.

In Zaragoza the demonstration area aim is to show how energy savings can best be achieved with a limited budget in social housing. Intervention is expected in wall and roof insulation and glazing replacement.
