Field work with participants showed that urban forests hold the potential for psychological restoration not only in daytime but even after dark both with fixed or portable electric lighting; lowered, low-level, warm-tuned lighting still supported pedestrians’ walking needs, and, to some extent, provided positive experiences.
In the comparison of conditions with and without snow simulated in the digital twin, the consistent finding was that the snow condition was appraised more favorable in both daylight and electric lighting conditions. The team enabled transdisciplinary collaboration in particular between environmental psychology, lighting design and computer science in the digital twin. Moreover, results have been discussed in relation to ecology. The project had a close collaboration with the municipalities of Uppsala and Ålesund in the on-site evaluations of lighting conditions.
