| Popis: | Daylight Redirecting Components (DRCs) guide daylight to zones with insufficient daylight exposure. They reduce energy demand for lighting, heating and cooling, and improve visual and thermal comfort. The data-driven model in Radiance is a general means to model DRCs in daylight simulation. Rather than internal optical mechanisms, their resulting Bidirectional Scattering Distribution Function (BSDF) is replicated. In our paper, we present models of two DRCs that are generated from measurements. The impact of interpolation between sparse measurements, of extrapolation for directions that cannot be measured, and of the directional resolution of the model are evaluated. It is shown that data-driven models can provide a realistic representation of both DRCs. The sensitivity to effects from interpolation differ for the two DRCs due to different complexity of their BSDFs. Due to the irregularity of the measured BSDFs, extrapolation is not reliable and fails for both tested DRCs. Different measurement and modeling protocols should be applied to different classes systems, rather than aiming at a common low-resolution discretization. + ID der Publikation: hslu_48065 + Art des Beitrages: Referat/Vortrag + Sprache: Englisch + Letzte Aktualisierung: 2017-05-31 14:49:27 |
