Urban vitality, fatum or fortuna?

The Non-Experts’ Experience of 3D City Visualisations

Vertical urbanisation is perceived as necessary to accommodate a growing population but is associated with severe risks for human well-being. It requires a profound understanding of how archi-tectural designs can ensure visually readable and liveable environments before it has been built. How-ever, current digital representation techniques fail to address the diverse interests of non-experts. Emerging biometric technologies may deliver the missing user information to involve (future) inhabit-ants at different stages of the planning process. The study aims to gain insight into how non-experts (visually) experience 3D city visualizations of designed urban areas. In two laboratory studies, univer-sity students were randomly assigned to view a set of the same level of detail images from one of two planned urban area developments in the Netherlands. Using eye-tracking technology, the visual behav-iour metrics of fixation count and duration and general eye-movement patterns were recorded for each image, followed by a short survey. The results show how visual behaviour and perception are remark-ably similar across different detail levels, implying that 3D visualizations of planned urban develop-ments can be examined by non-experts much earlier in the design process than previously thought.

The Urban Pergola : street furniture of the future?

Due to climate change, rising temperatures lead to more extreme heat stress in urban areas. Last summer, there were poignant images of people looking for shade in cities. Trees are effective measures to provide shade and decrease the perceived temperature. However, trees cannot grow in healthy conditions due to the conflicting interests of the many functions and infrastructure in cities. Also time is a limiting factor; before trees are fully grown and can fulfil its various functions (shade, biodiversity, appearance), it takes not only physical space but also time. Alternative interventions, such as a pergola, can help increase urban resilience by reducing the negative impacts of climate change.Pergolas are known, for example, in more southern Europe cities. However, despite the described promising effects of the pergola in documents to reduce heat stress and provide shade, we barely see these structures in the Dutch public space. We all know the pergola as an esthetical piece in the backyard where it provides shade, privacy and contributes to well-being, but they are not widely used in the public realm.Next to that, there are few or no known preconditions for an urban pergola. The functions that an urban pergola can offer go beyond providing shade. The pergola might help reduce noise and pollution, provide a meeting place in a neighbourhood and support biodiversity. Since space is scarce in cities where many different interests come together, we want to explore the potential contribution of an urban pergola to different problems. Therefore, at the Amsterdam University of Applied Sciences, we have worked on an urban pergola as a real 'boundary object' where we bring education, research, municipalities, and entrepreneurs across disciplines and sectors together to discuss the potential of such an object.For this workshop, we would like to show our first results of this interdisciplinary action research and continue answering the question: how can a pergola fit in the Dutch urban area? Therefore, we would like to explore the functions and forms of the urban pergola with stakeholders, such as municipalities, entrepreneurs, citizens, students, and researchers all from different disciplines. The desired outcome of this workshop is a joint proposal for implementing urban pergolas that can meet the versatile needs of cities and thereby make cities more liveable.

Using neuro-architecture to reinforce participatory planning and design

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.

Transformation towards green cities

Cities worldwide are growing at unprecedented rates, compromising their surrounding landscapes, and consuming many scarce resources. As a consequence, this will increase the compactness of cities and will also decrease the availability of urban green space. In recent years, many Dutch municipalities have cut back on municipal green space and itsmaintenance. To offer a liveable environment in 30 to 50 years, cities must face challenges head-on and strive to create green urban areas that build on liveable and coherent sustainable circular subsystems.

Liveable streets in Hanoi: a principal component analysis

Liveability along four streets in Hanoi, Vietnam is assessed. Hanoi is a rapidly growing metropolis characterised by high levels of personal motorized traffic. Two high traffic volume streets and two low traffic volume streets were studied using a mixed methods approach, combining the collection and analysis of quantitative and qualitative data on traffic volumes and liveability perceptions of its residents. The research methodology for this study revisits part of the well-known Liveable Streets study for San Francisco by Appleyard et al. (1981). A Principal Component Analysis (PCA) shows that residents on both low traffic volume streets experience less traffic hazard and stress, including noise and air pollution, than neighbouring high traffic volume streets. In line with Appleyard, the study shows that low traffic volume streets were rated more liveable than high traffic volume streets. In contrast to Appleyard, however, the study also shows that traffic volumes are not correlated with social interaction, feeling of privacy and sense of home, which is likely caused by the high levels of collectivism typical for Vietnam. Finally, the study indicates a strong residential neighbourhood type dissonance, where a mismatch exists between preferences for living in peaceful and quiet streets and the actual home location of residents.
