LiDICS: A FMI-based light dynamics interface for the control evaluation of complex fenestration

Abstract

This paper presents an interface for complex light dynamics coupled within a multi-domain simulation framework. The model is derived from ray-tracing data by novel incidence operator regularization (ior). After hemispherical integration, a functional mock-up unit (FMU) is automatically generated using the developed Modelica library and the OMPython API. LiDICS is applied to switchable membrane cushion constructions featuring inhomogeneous and complementary printing patterns. Solar and visual raw data have been generated using Klems and the three-phase method, respectively. The solar incidence operator solution obtained through the ior method aligns with the raw data, achieving a mean coefficient of determination r2=97.2% and a standard deviation of sigma=1.8%.
