The systems incorporate key enabling technologies related to integrating renewables, thermal storage, smart management and new materials.

The SUDOKET promotes research, innovation and the development of solutions based on key enabling technologies or KETs for the construction industry: technologies related to the integration of renewables, thermal storage, smart management and new materials.

SUDOKET consists of four pilot installations aimed at validating performance and demonstrating the use of advanced systems based on these technologies. TECNALIA’s energy experts have been involved in planning, designing, developing and installing two of these demonstrators:

  • Installation at the UPC in Tarrasa (Barcelona, Spain) with advanced solar systems for supplying solar electricity.
  • Installation at Cartif (Valladolid, Spain) for demonstrating advanced building materials and systems.
  • Installations at LNEG and NOVA School of Science and Technology (Lisbon, Portugal) with innovative smart management systems for buildings.
  • Installation at Nobatek/INEF4 (Bordeaux, France) with thermal energy storage systems.

Advanced solar systems

Bifacial photovoltaic (PV) systems were monitored in the advanced solar systems demo. Four bifacial PV systems were installed on the terrace of the UPC in Tarrasa to analyse their efficiency, along with a fifth equivalent monofacial system as a reference.

Bifacial systems can produce electricity not only from the radiation received on the front side of the modules but also on the back side, which is illuminated by the reflectance of the ground. Bifacial PV modules significantly increase the PV output of systems installed on flat roofs, particularly when combined with highly reflective surfaces.

We successfully validated a solar trigeneration system for one year. The technology, which was jointly developed with Energy Panel, consists of high-efficiency hybrid solar panels (70 %) combined with a double-assisted heat pump controlled by a smart energy manager, which maximises self-consumption while minimising operating costs.

The system provided the offices with more than 6 MWh of electricity and 20 MWh of heating and cooling for air conditioning. The solution is commercially available from Energy Panel.
