Impacts of Atrium Geometric Characteristics in University Research Buildings on Occupants’ Restorative Performance

Abstract

University researchers who spend prolonged periods in indoor environments are prone to increased psychological stress and decreased attention, which is widely confirmed in previous research. Indoor open spaces in research buildings, particularly atriums, are recognized as restorative environments that can provide a temporary escape from work areas, facilitating emotional and cognitive recovery. Existing studies have primarily focused on the physical environmental performance of atrium, such as daylighting and ventilation. Although the geometric characteristics of atrium have been shown to influence indoor environmental performance, empirical evidence on their effects on occupants’ restorative experiences remains limited, which constrains a comprehensive evaluation of atrium performance.This study aims to investigate the effects of atrium geometric characteristics on occupants’ restorative performance in university research buildings through virtual reality. 6 experimental scenarios were designed, covering 4 geometric variables: bidirectional expansion, unidirectional elongation, number of stories, and overall form. 30 participants were recruited, and both psychological and physiological data were collected. The results indicate that certain experimental conditions significantly enhanced psychological restorative effects, whereas no significant between-scenario differences were observed in physiological indicators. This study empirically examines the restorative potential of indoor atrium geometry and provides methodological and theoretical contributions for evidence-based design of built environments aimed at enhancing occupants’ well-being.
