The greener the better? A virtual reality experiment for the effects of greenery types on underground space occupants’ psychophysiological health and cognitive performance

Due to the inherent limitations of underground space, such as lack of connectivity with the aboveground environment, natural ventilation, and sunlight, underground space occupants tend to face more health risks than their aboveground counterparts. Greenery has been identified as one of the key elements fostering underground occupants’ health. However, it remains unclear whether different types of greenery have differential effects on occupants in underground space. This study thus aims to investigate the impacts of different types of greenery on underground occupants’ psychophysiological health and cognitive performance through virtual reality (VR). Four scenes (i.e., 2D green wallpaper, individual 3D plants, 3D plant wall, and no greenery) were created in virtual models. Thirty-two subjects were recruited, and randomly separated into four groups. During the experiment, subjects were required to complete four cognitive tests. Meanwhile, their psychophysiological states were measured using the indicators of heart rates and skin temperatures. Paired t-tests and Wilcoxon signed-rank tests were adopted to compare subjects’ health conditions before and during the cognitive tests. ANOVA and Kruskal-Wallis tests were applied to conduct inter-group comparisons. The cognitive tests have resulted in a significant increase in psychophysiological stress among subjects in the non-green scene (p<0.05), which proved the validity of the experiment setting. The results indicated that: i) greenery did not have significant impacts on underground space occupants’ cognitive performance; ii) all three types of greenery could alleviate the stress of underground space occupants; and iii) there was no significant difference regarding the alleviating effect among the three greenery groups. The findings imply that, from the perspective of underground space occupants’ health, types of greenery do not make a significant difference. Taking design and maintenance costs into consideration, 2D green wallpaper could be the most efficient option among the three covered in this study.
