Outdoor urban lighting design is a complex issue. It involves multiple aspects (energy consumption, lighting pollution, aesthetics, and safety) that must be balanced to make sustainable decisions. Although the energy and environmental issues assumed a driving role in the optimization of the urban lighting design, its impact on the psychophysical well-being of individuals has received less attention. Artificial lighting has been shown to add several meanings to an individual’s experience of space: affective (affect, emotion, mood), cognitive (attention, imagination, perception), associative (memory, judgment), and motivational (closeness, openness, communication). Traditionally, studies on the effects of lighting on individuals’ emotions have mainly focused on indoor spaces, while the present study aims to investigate the influence of lighting on individuals’ emotions in an outdoor environment. Participants experienced a simulated urban park through virtual reality. Specifically, the urban park was shown with different combinations of overall illuminance (high vs medium vs low) and correlated colour temperature (CCT) (warm vs intermediate vs cool). For each combination, participants were asked to judge how they felt. In general, results showed that high-intensity cool light made participants more nervous, while warm light made individuals feel more tired and less motivated to explore the park. In contrast, an intermediate CCT at low or medium illuminance impacted individuals p...
