“…Though well-validated by empirical studies, the IBE-QoL model was developed and verified based on aboveground built environment in previous studies (e.g. Leung et al, 2019Leung et al, , 2020Leung et al, , 2021. However, underground development users have special needs that are different from aboveground users, such as connectivity with aboveground environment, higher needs for greenery, etc.…”

Based on the IBE-QoL model (Leung et al, 2019(Leung et al, , 2020(Leung et al, , 2021 and the extensive literature review on underground environment, a conceptual model is developed (Refer to Figure 1).

“…Although the effects of indoor built environment on occupant health have been supported by previous studies (Awada et al, 2021;Yu et al, 2017), research investigating environmental health risk in underground developments is rare. Based on the Indoor Built Environment-Quality of Life (IBE-QoL) model developed for aboveground developments (Leung et al, 2019(Leung et al, , 2020(Leung et al, , 2021 and an extensive review of the underground literature, underground environment influencing users' health can be categorized into three aspects, namely, building services (visual comfort, acoustic comfort, thermal comfort, indoor air quality and ventilation), space design (lifts and escalators, transit connections with the world above, atrium, wayfinding support (Sterling, 1993;Lee et al, 2017)) and supporting elements (greenery like plants, landscaping (Bringslimark et al, 2011) and green wall (Tabatabaee et al, 2021)).…”

PurposeDue to land resource scarcity, sustainable urban development in high-density cities has long been challenging. As such, many cities are formulating plans to “dig deep”, resulting in more citizens working and/or staying underground for longer periods of time. However, owing to the particularities of underground space, the factors involved in the creation of a healthy environment are different from those involved in aboveground developments. This study thus aims to investigate the influences of various underground environment factors on users' health through a holistic approach.Design/methodology/approachTo achieve this aim, 12 underground sites and 12 corresponding aboveground sites are selected for a large-scale questionnaire survey, resulting in 651 survey samples. The survey covers post-occupancy evaluation of health (physical and psychosocial), underground environmental quality (visual, thermal, acoustic comfort, indoor air quality and ventilation), space design and greenery. Independent-sample T-test, Pearson correlation, multiple regression modelling and structural equation modelling are used to investigate whether significant differences exist between health of underground and aboveground users, and to develop an underground environment-health model for unveiling the significant associations between underground environment factors and users' health. To cross validate the results, an objective field measurement study is further conducted on six underground sites. The objective measurement results are used to cross validate the survey results.FindingsThe questionnaire results provide the following evidence: (1) health of underground users is significantly poorer than that of their aboveground counterparts; (2) underground development users' health is significantly affected by space design, greenery and environmental quality in terms of thermal comfort, indoor air quality, ventilation and acoustic comfort but not visual comfort; and (3) amongst the various identified factors, space design has the strongest predicting effects on human health. The field study echoes the survey findings and further unveils the relationships between different environmental factors and human health.Originality/valueThe results shed light on the importance of distinguishing between underground developments and aboveground ones in various guidelines and standards, especially those related to space management.

“…The built environment refers to the artificial surroundings for human activities (Leung et al, 2020). It is a broad concept including three components: planning, supporting facilities, and building services (Leung et al, 2021). Planning refers to the layout and landscape design of the open spaces, which consists of the size, green space, fountain, recreational courts, sitting area, etc., in the whole garden.…”

“…The diverse color of plants may benefit older people's special memory by strengthening the encoding-specificity effect, especially in natural scenes (Park et al, 2016). Building services aim to keep a comfortable environment for visitors (Leung et al, 2021). In the open spaces, it mainly includes the artificial lighting environment in the evening.…”

Many older people are facing various risks of cognitive impairment, while outdoor activities in open spaces may be helpful for their cognitive health. However, the effect of open spaces on cognitive health is unclear. This study aims to investigate the relationships between the cognitive health of older people and the built environment of open spaces. A questionnaire survey of 60 older people aged 60 and above was conducted. Results identified three major components of the built environment of open spaces, namely, planning, supporting facilities, and building services. According to the correlation and regression analysis, it is revealed that 8 BEOS items, including green ratio, a width of the pathway, maintenance of the whole garden, the color of green space, diversity of plants, location, and font of signage, artificial light of sitting area were positively related to memory, while only the size was negatively associated with memory. Only the green ratio could positively predict the concentration. The judgment was positively influenced by the green ratio, width of pathways, maintenance of the whole garden, color of green space and diversity of plants. A BEOS – cognitive health model for older people was built in this study. The results highlighted the importance of plants for cognitive health. Several recommendations, such as not-so-large sizes and diverse plants with vivid colors and signages with big fonts, etc., were proposed to improve the built environment of the open spaces and support the declining cognitive health of older people.
