Project R-10998

SUNOVATE (Research)

Producing Infrared light regulating pigmented polymer films on a pilot scale, and demonstration of the films in the respective building integrated systems/devices at TRL level 6 in: - building integrated windows, in which IR light regulating films are used to laminate glass sheets. The foils are permeable to IR light at low temperatures and IR light resistant at temperatures above 25°C. The foil automatically switches between the two functionalities based on its temperature. Visible light is transmitted at all times. Demo windows with this foil will be installed in a test building on the TU/e Campus in Eindhoven and/or EnergyVille in Genk, and the operation will be monitored continuously and in real-time using an integrated temperature sensor and window mounted spectrophotometers. To what extent energy savings and CO2 emission reductions lead to the use of this foil, will be calculated using. common software in architecture. - building-integrated BIPV panels, in which IR-light regulating foils are used as an encapsulant to laminate the glass sheet to the rest of the panel. The foils allow light to pass through, which is converted to electricity in the panel, and reject IR light that has too little energy to generate electricity (sub-bandgap wavelengths). Demo-BIPV panels with this foil will be installed in a test building at the TU/e Campus in Eindhoven and at EnergyVille in Genk, and the operation will be monitored continuously and in real-time using an integrated temperature sensor and measuring equipment to determine the electricity yield. The amount of extra electricity generated by these IR light-regulating foils will be determined by monitoring the yield in real time for at least 1 year. The same BIPV panels with non-pigmented films will be used as reference in these real-life tests.
