In Zaragoza, RENAISSANCE project has permitted a total reduction of 2,831 tons CO2/year. Two districts are concerned and represent about 80,840 sqm:
Valdespartera’s ecocity: construction of 616 bioclimatic buildings and the Sustainable Town Planning Center.
These constructions are included in an urban development of 10,000 new households. This urbanization plan meets bioclimatic criterias with high energy performance (superior than national standard level). The « CONCERTO district » enables to go further more with energy savings of 65% for heating and 30 to 45% for the others energy consumption centers.
El Picarral district: refurbishment with bioclimatic criteria of 196 social housings and the « Candido Domingo » public school.

This new district, situated on the south of the city, presents about 10,000 households (for the most part social). From designing to construction, the district was developed with bioclimatic criterias.

El Picarral is situated on the left bank of the river Ebro, included in the 21 urban complexes of Zaragoza (that means approximately 8,000 housings). This district wanted to recover and revitalize the social housings built between 1945 and 1960.
In Valdespartera’s ecocity, RENAISSANCE project allow the construction of 616 bioclimatic housings in a district including advanced service networks : a system of pneumatic garbage collection, a double separate water system...etc.... Valdespartera’s urban planning policy has been recognised as a worldwide "Good Practice" for two consecutive years.
In Saragossa, innovation is based on novative teaching aids in order to sensitize users at energy moderation. The evaluation will enable to better understand the perception and the social acceptance linked to innovative techniques and the habits to have.
In Valdespartera’s ecocity, 141 households are equipped with measurement devices. Datas are collected by the Sustainable Town Planning Center which advocates and promotes energy policy. Exhibitions and seminars are organized and the inhabitants are provided with training sessions. Thanks to the monitoring of some dwellings, it is possible to sensitize them through their present energy consumption.
In El Picarral, the experience of the “Candido Domingo” Public School refurbishment is another teaching aid and is disseminated through specific trainings as a concrete example.

In El Picarral (and elsewhere in Zaragoza), socio-economic research is undertaken into perception and acceptance of new technologies and habits. A sustainable policy development to improve the quality of life will be based on these informations.
In Valdespartera, the comprehensive monitoring systems produce innovative results. In combination with the environmental monitoring project undertaken and the existing thermal map of Zaragoza, this investment produces new data to fuel technical research to quantify the contribution of microclimates and bio-climatic elements to energy efficiency and the effects of local energy generation and consumption patterns on the local distribution system.
The results provide empowering design tools for architects, criteria for planners and confidence for energy companies interested in developing generation and distribution networks.
Last but nor least, research aims to develop an novative Energy Services Company (ESCO) model based on existing research and feasibility assessments carried out in Zaragoza and Lyon, and models of successful ESCO development drawn from across Europe.
