Modeling and simulation of daylight control systems

In the course of the energy turnaround, buildings have to become more efficient in their use of natural resources. At the same time, the growing comfort requirements of the users must be met. The CC EASE highlights the extent to which this is possible.

Overview

Das Ziel ist die Entwicklung eines Expertentools. Mit diesem soll die Eignung und Optimierung von Tageslichtlenksystemen für verschiedene Klimazonen untersucht werden. Dazu müssen neue Modelle entwickelt werden, mit denen komplexe Oberflächeneigenschaften in einer klimabasierten Tageslichtsimulation hinreichend genau abgebildet werden können. Unterscheiden werden Tageslichtlenksysteme mit kleinen Strukturen, z.B. Mikroprismen aus Glas oder strukturierte Spiegel, von grösseren Strukturen, zu denen Lichtschwerter, hohle Lichtleiter und grossformatige Lamellen gehören. Durch den Vergleich mit Messdaten werden die Modelle und Implementierungen validiert. Abschliessend werden die Leistungsdaten für die modellierten Tageslichtlenksysteme ermittelt und für potentielle Anwender solcher Systeme aufbereitet und dargestellt.
