The thermal inertia is one of the fundamental elements of passive architecture and has been present as a thermal regulator in buildings constructed ever since man began building. Therefore, it is surprising that in the current context, where energy efficiency is essential and the goal of building nearly zero energy buildings is commonly shared, thermal inertia is not in the center of the debate and of the architectural proposals. This building intends to claim the thermal inertia as a fundamental element of the design of an almost zero building energy consumption, considering fundamental part of the climate control system, supported by passive systems, which are given priority in front of the machinery, and use local energies. This, coupled with the commitment to a simple technology that facilitates full maintenance, and the flexibility to adapt to new uses, aims to demonstrate that it is possible and affordable to build a sustainable public building, adapted to the end user, against the excesses of our recent construction of public buildings in the rural p.

Owner approach of sustainability
The City Council aims to create a cultural tourism resource, that is a reference for agrifood in the region. The aim is to promote a food companies incubator where small local producers display their products and tourists can taste them and buy them. In addition, the Center will offer agrifood training courses, events, product presentations and connect producers together to create synergies.
In the context of an economic crisis and bad recent experiences in raising public buildings in rural areas, and with a budget of less than 850 € / m2, the main goal we set ourselves was to design a building with a minimal environmental impact that has the lowest energy consumption. Measures have been implemented to REDUCE THERMAL DEMAND lowering the overall transmittance of the building with a continous envelope of high isolation (SATE and efficient joinery) and lowering consumption peaks for cooling through the High Thermal Inertia of the building. It also acts as a heat reservoir, causing a reduction of the thermal demand at their maximum and minimum points. In addition the building is protected from the summer sun by cantilevered, mobile lattices and thermal blinds driven by sun sensors and space advantage by thermal recovery mattress with hot air in winter. The other important measure is the use of local energy: solar gain in winter through windows with blinds operated with solar sensors, passive use of geothermal energy through bioclimatic gallery, night cooling, passive ventilation system. With these measures, energy demand is reduced to more than 50% energy demand and it is possible to avoid having to install a mechanical refrigeration system which increases the initial cost and burdens to the municipality with significant energy costs and maintenance, understanding that in this climate, and applying correctly passive measures is not necessary. The other objectives that have conditioned the design are ease of maintenance, designing systems to operate by the end user simple, easy technology, and does not depend on skilled labor; cleanability, especially of timber and soils; Building flexibility to accommodate different activities, including a future change of use to help amortization; and integration into the urban center of Cebreros, gaining prominence for its use and not for their visual impact.

Indoor Air quality
The building is located in the center of Cebreros, near the plaza, between two of the most important public buildings, the church and the Cabildo (cultural center). Its integration strategy is to visually and physically connect the two buildings, as a covered square, and establish itself as the protagonist of the urban scene for their activities, not its visual presence.

Reasons for participating in the competition(s)- Integrarse en el ecosistema,responder a las condiciones socioculturales de la comarca y ser referente de laagroeconomía local.
- integrarse en el centro urbanode Cebreros, conectando física y visualmente los dos principales edificiospúblicos del pueblo, enriqueciendo la escena urbana por medio de su uso yactividad.
- Reducir el consumo energético amás del 50% de un edificio convencional, cubriendo la mayor parte de la demandapor medios pasivos y con energías locales.
- Evitar instalar un equipo derefrigeración mecánica, combinando la inercia térmica con sistemas deventilación a través de la galería bioclimática y la refrigeración nocturna.
- Priorizarla facilidad de mantenimiento para que se pueda realizar por mano de obra noespecializada y no cargar así al ayuntamiento con excesivos gastos. Renunciar aincorporar tecnología compleja y costosa que pudiese complicar elmantenimiento, ya que este debe ser sencillo y acorde con los recursostecnológicos de la comarca.
- Diseñar un edificio flexible,que pueda albergar diferentes tipos de actividades, con las instalacionesaccesibles para facilitar las modificaciones y con posibilidad de adaptación adiferentes usos .
- Limitar su coste de construcción a 811 €/m2.
