Office Lighting (05-10-23)
Van de Perre, Smet, Hanselaer, Dujardin, and Ryckaert evaluated the consequences of different lightscapes in windowless offices. They report that “A two-interval-forced-choice experiment was conducted with the 20 lighting scenes derived from five CCTs [correlated color temperatures] (2500–10 000 K) and four luminances (12–120 cd/m²). The results from 20 observers showed that a higher wall luminance significantly increased brightness.
