Weak points •Initial budget (and objectives during the initial 4

years) were 50% of the final budget. •Has been necessary to adjust the targets in two

moments, 2009 and 2011, late in the project. •Discontinuity of dwellings occupation.

Strong points:•An adequate size and profile of the University team•An adequate final budget for equipment•A well complemented set of objectives

The flexibility of the research team has allowed to adapt the goals and expand the field of research with new developments of evident interest in urban planning (URSUS, ISLAND HEAT, ESCo).This has been one of the conclussions of the Conference-Debate organized by IDEA in the recent GENERA / IFEMA

The seven years project suppose no more than two for the new incorporated tasks. Despite this limitation, the objectives have been successfully met. Furthermore, lines of continuity have been defined in order to keep the work with residents since it is clear the potential of a project like Renaissance in a living lab as Valdespartera is.

Further actions on R&D beyond the end of Renaissance

Looking ahead:The potential eco-city Valdespartera has for a continuous process of R & D is evident:

• Nearly three hundred probes installed.• Energy balance considering consumption of electricity, gas and water for more than 2000 homes.• A public place for seminars, exhibitions, debates that the Center for Sustainable Urbanism provides.• A partnership and a set of neighbors very involved and willing to continue the effort that it is being incorporated with the final stage.

Performed tests involve the implementation of an automatic mode of interaction with users so that from

• the user typologies defined• selected events as relevant to saving actions and• the corresponding messages in various communication systems (web, sms,…)

it will be possible to generalize the system to support generic users.

In web renaissance.unizar.es the information is available byuser -accessible password

This actions combined with the initial track and a rotation of probes will allow to any interested user a "universal" use once typologies, events and recommendations is completed.

ConclusionsConclusions

Progress in communication with users and investments made under the project deserve a continuity on some of the tasks carried out during the last period of the projectIn order to make this possible, the next months a series of final works should be carried out for a proper diffusion

• IDAE + users +GEE agreement to evaluate the Solar Thermal situation.

• Automation of procedures to make them endless with little or no cost for the current support to Valdespartera and Picarral residents, and schools involved as well

• Generalization of the methodology to allow the use on public buildings as a strong tool for ESCos.

• Publication of a comprehensive and detailed document analyzing the operation and urban planning results and the failures and limitations that have been found.

• These results and operative conclusions will be transferred to local end national authorities as information of interest for future actions.
