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

André Gabriel Kostro, Josef Andreas Schuler, Philippe Couty

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 ...

Feasibility study on a novel daylighting system with embedded micro compound parabolic concentrators (CPCs)

Jean-Louis Scartezzini, Andreas Schueler, André Gabriel Kostro, Jing Gong

A novel glazing system consisting of a polymer layer with embedded micro compound parabolic concentrators (CPCs), which is attached to a glass pane of glazing, is proposed. It aims to reduce the energy consumption due to cooling in buildings, provide dayli ...
