The site of the proposed building is located in the neighbourhood of “La Carrasca” in the city of Valencia. Specifically, it comprises a plot of 7,738 m² with two existing structures (Block A and Block B), belonging to the University of Valencia. The new project occupies 2,349.69 m² of that space. A key aspect of the project is the connection of the new building (Block C) with Block B and the intermediate street between them.

We used the public competition documents, including floor plans with a preliminary layout and a schedule of areas drawn up by the Technical Unit of the University of Valencia, to carry out an exhaustive analysis of the programme, the needs and the bioclimatic performance of the building. This analysis informed the further development of our proposal.

The building, a two-storey volume with a basement, houses the following functions: offices, classrooms, workrooms, meeting rooms and an assembly hall. Due to their high internal heat loads, the offices, classrooms and workrooms tend to overheat. The new Research Institute has been designed to take advantage of the excess heat in winter and dissipate it in the summer. We developed the building as an adaptable and flexible construction, adaptable to possible changes of use, developing several simultaneous strategies that complement each other.

A concrete structure has been chosen: a durable, low-cost material with high thermal inertia. It contributes directly to the passive energy management of the building. In the upper parts of the structure, the thermal mass is activated by radiant systems.

The concrete construction is enveloped and protected by a low-cost and bioclimatic outer skin which, by opening and closing, regulates sunlight and ventilation, improving the interior temperature naturally and maintaining a high level of comfort in the intermediate and circulation spaces.

Inside this improved climate, well-insulated wooden boxes with movable glass elements provide comfortable conditions in the workspaces. The layout of these boxes changes on each floor to suit the needs of their users. This creates generous and indeterminate spaces, which are linked to the common areas and create informal opportunities for breaks and interpersonal exchanges.

The building has been designed to maximise passive energy recovery and minimise the use of non-renewable sources. The building constantly reacts and adapts, opens and closes itself, activates and deactivates itself. This creates a genuine physical comfort that sets the space apart from conventional, artificial work environments.

For the primary structure, we have opted for a long-lasting mineral material with high thermal inertia. The secondary enclosures use materials of organic or recycled origin and reversible dry construction systems, thus ensuring a low environmental impact.
