• Small green roofs may offer experiential benefits for people in dense urban areas. • The respondents scored high for perceived restorativeness on the study roof. • Also, e.g. joy, beauty, excitement, tempting nature and fresh air were often mentioned. • Practitioners can use the results in planning and design. Growing and densifying cities set challenges for preserving and enhancing sufficient and good quality green urban environment. Rooftops offer vacant room for additional urban greening that may contribute to the well-being of people and the liveability of cities, but this potential lacks empirical support. In spite of the fact that even small green spaces produce, for example restorative experiences, the literature concerning the experiential and recreational benefits of green roofs is still scarce. To identify the experiential potential of a small urban green roof we explored restorative and other experiences of 178 people visiting a sparsely vegetated green roof in the centre of Helsinki, Finland, using a questionnaire. We showed that the studied green roof provided restorative and other positive experiences to the visitors. The level of perceived restorativeness was relatively high. In addition, the results revealed multiple perceived qualities that reflected visual as well as other sensory experiences, beauty, suitability of the place for oneself and the urban context, nature, desire to explore the place and interestedness, positive excitement, and safety. Furthermore, answers to the open questions revealed a wide range of other observations and feelings, such as peace, joy, excitement and hope. Our study indicates that even a small and rather ascetic accessible green roof has potential to offer a moment of respite in the middle of urban everyday hassle, thus implying that these kinds of solutions may allow for a pinch of beneficial green in places where more diverse and lusher solutions are not possible due to, e.g. the load capacity of a roof.

Within the context of enhancing sustainable and livable urban environments, one aim is to establish multifunctional green infrastructure (GI). We argue that in order to successfully plan and manage the development of GI, an inclusive and future-oriented stance concerning the needs and expectations of urbanites is required. By using green roofs as an example, the aim of this paper was to offer insights into how people envisage novel GI in urban environments and to reveal the scope of meanings and values people attach to these kinds of green infrastructure. We present results based on 149 stories collected with the method of empathy-based stories. Respondents were asked to use their imagination to produce mental images of not-yet-existing green roofs in different urban situations. Our results reflect a rich set of dimensions of green roofs that the respondents vividly imagined. Green roofs may contribute to the livability of urban areas in multiple ways, such as strengthening social cohesion, providing space for everyday renewal and restoration, offering interesting sceneries and multisensory experiences, softening the hard cityscape, showing ephemeral events and making experiences of “height” possible, as well as increasing the “contact with nature” experiences for residents, e.g. through biodiverse nature in the middle of built environments. Furthermore, the need for local, customized solutions that offer different benefits and experiences was expressed. Using both qualitative and quantitative analyses, we idealized four green roof meta-types for understanding the diverse expectations people may have for green roofs in urban area: Urban farm, Oasis, Urban hill and Meadow. Based on our results we suggest that comprehensive experiences and needs of people should be taken into account when designing urban green roofs or urban green in general – not only, e.g. visual pleasure. Also, site- and user-specific solutions should be considered instead of generally applied ones. Our results offer tools for, e.g. urban planners to understand the value of diverse green roof solutions to the user. [ABSTRACT FROM AUTHOR]

• We designed PEAQS to measure the perceived aesthetic qualities of environments. • The 23-staments refined version showed good internal consistency and predicted preference. • The tool discriminated aesthetic perceptions in the three sites urban green areas. Aesthetic qualities of urban green and blue spaces have received considerable attention in scientific literature but are operationalized in multiple ways and lack clear assessment and measurement techniques. To fill in this gap, we developed a Perceived Environmental Aesthetic Qualities Scale (PEAQS). Based on previous literature both in philosophy and empirical sciences we created a questionnaire with 36 statements and three open questions focusing on the perceived aesthetic qualities of environments. This questionnaire was used to sample 331 respondents in three sites different in their level of naturalness, human intervention and design: a natural-like but managed urban forest, a partly human-made and intensively managed bay-park and a completely human-made green roof. These sites were selected to represent a variety of urban green and blue infrastructure common in cities. The results suggest a scale that consists of 23 statements and five factors that reflect perceived aesthetic qualities of urban green spaces: Harmony, Mystery, Multisensority & Nature, Visual Spaciousness and Visual Diversity, and Sublimity. We give guidelines for further development and testing of the scale in order to prove its potential to develop the field of environmental aesthetics and to demonstrate its usefulness for adaptive, evidence-based urban planning and design.

The focus in this research was on the effects of restorative experiences in an immersive virtual reality (VR) forest environment. For 5 min one hundred participants used a VR application depicting a forest via a head-mounted display and headphones. The extent of the restorative effect on the participants was measured in terms of perceived restorative outcomes, vitality, and mood before and after using the VR application. After finding out that using the VR application improved the perceived restoration outcomes, vitality and mood of the participants, the perceived restoration of the VR environment was compared with experiences in physical forests. According to the results, the VR environment was generally perceived as restorative as the physical forest environments, and more fascinating and coherent. The results imply that VR technology could have an effective restorative function during a school or work day when there is no access to highly restorative natural environments. Knowledge about the restorative qualities of physical and virtual natural environments could be applied to develop both the virtual and physical environments that are currently available and where people have access to. • Restorative experiences were studied in a virtual reality forest environment. • The virtual reality had a positive effect on mood, vitality and restoration. • The results were compared to data on the restorativeness of physical forests. • Virtual forest was perceived as more or equally restorative. • Virtual reality could be used to enhance well-being in multiple use cases.
