The dataset comprises two spectral lighting simulation reference models – one office and one factory hall – designed to support full-spectral daylight and electric lighting simulations and facilitate evaluation of non-visual lighting effects. It includes CAD geometry of the scenes modelled in Rhino, comprehensive spectral material and light source data, window system BSDF data and weather data files. Further, it includes example implementations of the scenes in the two software tools Radiance and OWL to enable reproducible workflows and support adoption in other software platforms. The dataset is described in the journal article:Geisler-Moroder, D., Maskarenj, M., Ward, G., Wang, T., Lee, E. S., & Altomonte, S. (2026).
