Investigating the Psychological Impact of Green Space Elements in High-Density Housing Using VR: Insights from student dormitories Part 2 Dissertation 2025 Shuhan Chen Xi'an Jiaotong-Liverpool University | China This research explores how micro-scale green elements—such as vertical planting and framed window views—can improve psychological well-being in high-density student housing. I developed 24 parametric dormitory scenarios, each varying in green coverage, façade vegetation, window size, and elevation, and rendered them in immersive virtual reality (VR) for participants to experience directly.To analyse user responses, I combined semantic segmentation of visual scenes with AI-powered sentiment analysis of verbal feedback. This hybrid approach allowed for the quantification of emotional responses— such as stress, comfort, and attention—in relation to specific spatial features.Key findings highlight that the visibility and spatial arrangement of greenery, rather than quantity, most strongly affect emotional outcomes. Scenarios featuring moderate greenery, vertical façades, and small windows at mid-level elevations were consistently rated as calming, secure, and emotionally engaging. In contrast, excessive or poorly composed greenery often caused discomfort.This project contributes to biophilic and evidence-based design theory, while offering architects a data-informed, human-centred framework to assess emotional impacts before construction. It advocates for mentally supportive design in compact living environments, especially where space, privacy, and access to nature are limited. Tutor(s) Jiawen Han Marc Aurel Schnabel
