ACCIONA installs a new photovoltaic system integrated into the facade of one of its services offices in Barcelona


The installed system, which is part of the demonstration activities of the European STILORMADE project, has a dual functionality – to generate renewable energy and to reduce direct sunlight entering the glazed galleries

ACCIONA, through the R&D centre of its construction business, has launched a new photovoltaic system integrated into the facade of one of its services buildings in Barcelona. The initiative is part of the demonstration activities of the STILORMADE project, financed by the European Union through the HORIZON 2020 framework programme for research and innovation.

The system consists of a series of 48 high-efficiency photovoltaic modules distributed across the glass envelope on three of the building’s storeys. These modules, which have been manufactured by the French partner S’Tile, the company coordinating the project, in collaboration with the University of Vienna, have a specific design that maximises the solar area of the cells.

The installation has a dual objective. Firstly to generate renewable energy, all of which will be used by the building under a strict self-sufficiency system with battery storage, and secondly to provide shade to the glass galleries, reducing direct sunlight by 87%.

The integration of the modules on the building’s façade uses an aluminium structure that provides natural ventilation for the modules, improving their performance and extending their useful life.  Furthermore, the system significantly enhances the aesthetic value of the building.

Following the same approach as the system implemented in Barcelona, and as part of the same project, the same technology modules have been demonstrated in the construction of the roof of the “Halles de Laissac” market in Montpellier, France.

These works required the design and manufacture of 865 modules with different electrical and geometric characteristics in order to adapt them to the building’s circular shape roof, once again creating a highly functional but aesthetic result.

These demonstration activities are part of the same project, in which ACCIONA has already installed a total of 18 high-efficiency photovoltaic street lights at the end of last year in Molina de Segura (Murcia), as well as at the Calvia Beach The Plaza hotel (Mallorca), the Renault production plant in Valladolid and at other locations in Almería and Tudela del Duero (Valladolid).

These initiatives highlight ACCIONA’s commitment to implementing renewable energies and passive improvement measures in building construction.
