Amsterdam faces the challenge of accommodating 50,000 to 90,000 new homes in the next five to ten years. That is equivalent to 10% of the city’s current total housing stock. The new homes have to be built within the existing urban fabric. This will entail high densities and the construction of new ‘un-Dutch’ typologies with high-rise residential buildings. Densification is currently accelerating in many Western cities and high-rise living environments are gaining ground as today’s typology. Yet these new typologies come with potentially serious risks to the liveability of cities in general and those new environments in particular (Asgarzadeh et al. 2012; Lindal and Hartig 2013; Gifford 2007). Urban designers and (landscape) architects are challenged to prevent and soften the negative impact that is often associated with extremely densified environments. This entails mitigating contradictive demands: to create high-density capacity andshape streetscapes that relate to a human scale. Designers might resort to the large body of applied design solutions and theories, yet these tend to be derived from more traditional urban fabrics of low-density developments (for example: e.g. Sennett 2018; Haas 2008; Jacobs 1993; Banerjee and Southworth 1990; Alexander et.al. 1977; Jacobs 1961).Therefore, the question of the research project Sensing Streetscape is if the classical design solutions are without any alterations, applicable in these new high density settings and able to create streetscapes with a human scale. A combination of emerging technologies and principles from both worlds; neuroscience and architecture offer the opportunity to investigate this question in-depth as a relation between the designed and the visually perceived streetscape.

Large cities in the West respond to an ever-increasing shortage of affordable housing by accelerating the process of urban densification. Amsterdam, for instance, aims to increase its housing stock by 10 percent in the next 15 years as its population is expected to grow by 20 percent. As in other cities, it seems inevitable that high-rise buildings with higher skyscrapers than in the past will be built within the existing urban fabric. Such large-scale (re)development projects shape the conditions for inhabitants’ eye-level experiences, perception of place and overall well-being. The new hybrid field of neuroarchitecture offers promising eye-tracking technology and theories for measuring inhabitants’ visual experiences of the city and rethinking the effectiveness of applied design principles across the globe. In this paper, the ‘classic’ design solutions for creating streetscapes on a human scale in densified areas have been assessed by eye-tracking 31 participants in a laboratory setting, all of whom viewed photographs of 15 existing streetscapes in high-rise environments. The study drew on theories from the field of neuroarchitecture and used input from a panel of (landscape) architects and urban designers to design the research and analyze the eye-tracked patterns. The results indicate that the classic design principles (horizontal–vertical rhythms and variety; active ground floor; tactile materials) play a significant role in people’s appreciation of the streetscape and that their attention is unconsciously captured by the presence of these principles. The absence of the design principles seems to result in a scattered ‘searching’ eye movement pattern. This also suggests that a coherent design of streetscapes in high-rise environments may contribute to a human scale at eye-level.

The coronavirus pandemic highlighted the vital role urban areas play in supporting citizens’ health and well-being (Ribeiro et al., 2021). In times of (personal) vulnerability, citizens depend on their neighbourhood for performing daily physical activities to restore their mental state, but public spaces currently fall short in fulfilling the appropriate requirements to achieve this. The situation is exacerbated by Western ambitions to densify through high-rise developments to meet the housing demand. In this process of urban densification, public spaces are the carriers where global trends, local ambitions and the conditions for the social fabric materialise (Battisto & Wilhelm, 2020). High-rise developments in particular will determine users’ experiences at street-level. Consequently, they have an enduring influence on the liveability of neighbourhoods for the coming decades but, regarding the application of urban design principles, their impact is hard to dissect (Gifford, 2007).Promising emerging technologies and methods from the new transdisciplinary field of neuroarchitecture may help identify and monitor the impact of certain physical characteristics on human well-being in an evidence-based way. In the two-year Sensing Streetscapes research study, biometric tools were tested in triangulation with traditional methods of surveys and expert panels. The study unearthed situational evidence of the relationship between designed and perceived spaces by investigating the visual properties and experience of high-density environments in six major Western cities. Biometric technologies—Eye-Tracking, Galvanic Skin Response, mouse movement software and sound recording—were applied in a series of four laboratory tests (see Spanjar & Suurenbroek, 2020) and one outdoor test (see Hollander et al., 2021). The main aim was to measure the effects of applied design principles on users’ experiences, arousal levels and appreciation.Unintentionally, the research study implied the creation of a 360° built-environment assessment tool. The assessment tool enables researchers and planners to analyse (high-density) urban developments and, in particular, the architectural attributes that (subliminally) affect users’ experience, influencing their behaviour and perception of place. The tool opens new opportunities for research and planning practice to deconstruct the successes of existing high-density developments and apply the lessons learned for a more advanced, evidence-based promotion of human health and well-being.ReferencesBattisto, D., & Wilhelm, J.

Background and objectivesBefore the Covid-19 pandemic, important social studies already indicated the severe negative feedback associated with high-rise developments. During the Covid-19 pandemic, citizens were confronted with their neighbourhoods’ insufficient restorative capacity to maintain their health and well-being. New methods are urgently required to analyse and learn from existing high-density developments to prevent a repetition of past mistakes and to catalyse the salutary effects of architecture in new developments.Process and methods (for empirical research)The Sensing Streetscapes research investigated the potential of emerging biometric technologies to examine the effects of commonly applied urban design principles in six western cities. In one outdoor and four laboratory tests, eye-tracking technology with sound-recording and Galvanic Skin Response captured subjects’ (un)conscious attention patterns and arousal levels when viewing streets on eye level. Triangulation with other techniques, such as mouse tracking to record participants’ appreciation value and expert panels from spatial design practice, showed the positive and negative impact of stimuli.Main results (or main arguments in the case of critical reviews)The preliminary results provide a dynamic understanding of urban experience and how it is affected by the presence or absence of design principles. The results suggest that streets with high levels of detail and variety may contribute to a high level of engagement with the built environment. It also shows that traffic is likely an important factor in causing stress and diminishing the restorative capacity society seeks.Implications for research and practice/policy | Importance and originality of the contributionThe research study led to the development of a Dynamic User Experience Assessment (D-UXA) tool that supports researchers and designers in understanding the impact of design decisions on users’ experience, spatial perception and (walking) behaviour. D-UXA enables a human-centred analysis and is designed to fill the gap between traditional empirical methods and aspirations for an evidence-based promotion of human health and wellbeing in (high-density) urban developments.

The use of biometric monitoring allow researchers insight into the processing of environmental data by our central nervous systems. As a result we can determine precisely which stimuli cause arousal or draw our attention. This technology is used widely by commercial interests but is not commonly used to improve the public realm. Our authors hope to change this.

Urban renewal and urban area development projects are by nature highly complex processes involving a multiplicity of professionals, stakeholders, and conflicting interests. Adding to this complexity are the formulated ambitions and societal challenges projects have to answer to. One of these ambitions emphasizes a more inclusive planning process, involving the inhabitants in all stages of the planning process. In terms of design, another challenge is to create environments on a human scale while building in high density such as with tall residential buildings. The metropolitan area of Amsterdam intends to have 100,000 new dwellings by 2025. Most of these dwellings have to be added within the existing urban fabric, planned on obsolete inner-city brownfield locations, at the waterfront, nearby highways whereas others are going to be built in deprived neighborhoods. The deprived neighborhoods are mainly located in the postwar areas of Amsterdam, on its northern, western, and south-eastern sides. The deprived neighborhood called the Bijlmermeer located on the south-eastern side of the city, for instance was the first high-rise development project in the Netherlands. It was designed as a single project with identical high-rise buildings in a hexagonal grid surrounded with large green spaces.These deprived, modernistic neighborhoods lack the classic housing block structures with a clear articulation of buildings and street spaces. They appear to be responsible for an ‘inhuman’ scale and demonstrate the lasting impact critical design flaws can have on the daily lives of inhabitants. Hence, the question is how to develop liveable environments where people feel fully supported by building architecture and streetscape configuration. To prevent new urban area developments that will again fail to incorporate human scale, scientific methods and user input are needed to inform the practice of planning and design, and their applied design solutions. Building on two research projects (one on participatory planning and the other on neuroarchitecture research), we explore how the newly emerging field of neuroarchitecture - and the eye-tracker in particular, might enhance urban area developments on a human scale.
