摘要

While a relatively small body of research links green roofs to psychological benefits such as aesthetic enjoyment and improved concentration, these outcomes are becoming important objectives in green roof design. Claims regarding benefits of green roofs are therefore often derived from research on psychological benefits of ground-level urban greenspaces. Compared with other urban landscapes, green roofs have limited space and accessibility, reducing the opportunity for physical exercise and the opportunity for larger masses of vegetation, particularly trees. Given these differences, there is a risk that the psychological benefits of green roofs are overstated or may only apply to a subset of green roof designs. Guidance for designing green roofs for psychological benefits may also be misleading if it fails to consider the unique green roof context. To address these challenges, we review research on psychological benefits of green roofs through a social-ecological lens on human-environment interactions. We consider how experiences of green roofs arise from an interaction between characteristics of the physical environment (including characteristics of green roof vegetation, wind patterns, and surrounding buildings), social climate (including social factors influencing access and use, and social norms for nature in cities), activities that can be undertaken on a green roof (such as exercise, socialisation, rest and relaxation), and individual resources and adaptation (for example, prior mood and opportunities to change environments to support individual needs). We explore how these factors interact with each other and with broader natural, built and socio-cultural systems that might encourage or inhibit opportunities to view, access, and enjoy green roofs. We conclude with recommendations regarding how green roofs can be designed to promote psychological benefits and identify future research needs.
