Hydrogen-based electricity storage optimization on buildings by coupling thermal and photovoltaic electricity production towards carbon neutrality

Self-sufficiency (SS) of buildings with low greenhouse gas (GHG) emissions can be obtained using photovoltaics (PV). To maximize self-consumption - minimizing the import of grid electricity - PV can be coupled with a hydrogen storage system converting the ...

From university to industry - challenges in upscaling optical microstructures for daylight redirection in buildings

Philippe Couty, Andreas Schueler, André Gabriel Kostro, Josef Andreas Schuler

In this paper we present some of the challenges faced when upscaling optical microstructures from a lab scale 1x1 cm sized proof of concept sample to a square meter sized object that can be installed in a building. The optical microstructure in question is ...

Integrating hourly life-cycle energy and carbon emissions of energy supply in buildings

Philippe Couty, Thomas Bernard Paul Jusselme, Stefano Cozza, Didier Albert Simon Vuarnoz

Huge amount of energy resources greenhouse gas (GHG) emissions is devoted to the built environment. Therefore, an accurate assessment method of these indicators is compulsory. To take advantage of the temporal variation in the primary energy use and associ ...

UV-nanoimprint lithography and large area roll-to-roll texturization with hyperbranched polymer nanocomposites for light-trapping applications

Aïcha Hessler-Wyser, Yves Leterrier, Philippe Couty, Diego Fischer, Rémy Teuscher, Caroline Calderone, Marina Aymara González Lazo

Light-trapping textures were produced in hyperbranched polymer (HBP) silica nanocomposites using a UV-nanoimprint lithography (UVNIL) replication method, either in batch or roll-to-roll processes. The hardness of the HBP was found to increase by a factor o ...
