The public library of Pompeu Fabra Mataró-Barcelona

Semi-transparent and opaque multifunctional photovoltaic-thermal modules to generate electricity and warm air from the sun were developed. They were designed industrially and implemented as curtain walls in the Public Library Pompeu Fabra of Mataró-Barcelona. The photovoltaic (PV) system was connected to the grid and their performance was studied and optimized.

The multifunctional thermo-PV module developed is suitable for use on buildings and is equipped with mono/polycrystalline and amorphous silicon cells. The PV cells of the facade were arranged in a patchwork fashion to create a transparency affect. A thermal system was an important innovation and buoyancy ventilation was integrated into the thermal system. Know-how in the field was shared between the partners. The modules can be used on the roof as well as on the facades and the improved thermal behaviour offers an energy cost reduction. On-site PV means that there are fewer land costs and less energy is lost in transporting and transforming the energy. The large semi-transparent ventilated modules are attractive as well as functional, showing protection from light, noise and weather. Monitoring the system showed that it has a performance ratio of 62 %, with thermal losses between 8 % and 15 %. Actual performance shows that 55 MWh per year can be produced by the PV system. The building is the first of its type in Spain and one of the first in the world.
