Visual guidelines for climate-responsive urban design

Communication of climate-responsive urban design guidelines is becoming increasingly relevant in the light of climate adaptation challenges in cities. Widespread uptake in practice of such guidelines can be promoted by visualizations of the principles on which they are based. The “Really cooling water bodies in cities” research project developed and tested the required knowledge on visual communication. Evidence-based design guidelines assisting designers with creating cooler urban water environments were developed and communicated with 3D animations. The animations were shaped according to three core theoretical criteria about visual representations: “visual clarity”, “trust” and “interest”. We assessed in how far these criteria were met in an inquiry with design professionals, the target group of the design guidelines. The article concludes with recommendations for developing visual design guidelines in climate-responsive urban design: to weigh the level of detail, components and balance between site-specificity/abstraction (“visual clarity”); to make microclimatic processes visible without distorting them (“trust”); and to keep timing short and visual attractiveness high (“interest”). It is argued that taking these aspects into account and setting a clear correspondence between theoretical concepts, representation objectives and options, can largely benefit visual design guidelines communicating climate-responsive urban design knowledge.

The riddle of the real city

Does our knowledge about city and urban planning have solid ground? Can historical research promote creative thinking? How can we theorise about urban design and architecture in our age of the media? These questions have guided the creation of this multi-layered, richly documented and illustrated triptych, in which the Dutch architectural theorist Wim Nijenhuis pursues a creative goal: to stimulate new ways of thinking in architectural culture.Each part of the triptych treats distinctive issues with a particular style of writing:I – a treatise on urban history. Using the archaeological-genealogical toolkit Nijenhuis reveals the difference between urbanistic discourse in the modern and the classical age; the first staging the street and public space, the latter adhering to representation and mathematical order. In great detail he shows how modern urbanism did not emerge from idealistic motives and technical urgencies, but from an accidental mix of medical, engineering and aesthetical parlances, and how classical thinking on the city dissociated from Renaissance by an intertwining of military science, political science, anthropology and ethics.II – a bundle of essays about the condition of the city in our media age. In strikingly composed texts the author prophesies how rapid traffic and transmission speed of media will distort the perception of our real cities. This gradual event will profoundly influence the cultural role of architecture.III – a set of meditations about epistemological problems. Questioning the practice of critical writing, Nijenhuis proposes change of subjectivity (and thereby worldview), ethical indifference, parody, curative mythomania and hypermodern dilettantism.The book is composed as a cloud essay that serves to enrich the reader’s theoretical understanding of urban interventions. Dialoguing with philosophers like Bataille, Deleuze, Foucault, Klossowski, Sloterdijk and Virilio, Nijenhuis covers multiple disciplines such as urbanism, architecture, history, media science, philosophy and art. Stretching urbanistic thinking beyond its limits he carries the reader along into the miraculous world of the street, the engineer, the norm, the form, order, fortresses, discipline, army camps, city frontiers, the Temple of Salomon, the quest for beauty, the ‘impressiveness’ of images, speed, the tragedy of the omnipolis, solidification of time, and the liquidising potency of apocalypticism and Taoist non-action.The Riddle of the Real City testifies to four experimental exercises: transitory subjectivism to reveal hidden dimensions of the person, transhistorical verticality to communicate with singular events from the past, theory as toolkit and pursuing a personal path in reading and investigation.

Introduction—The Hacker, the City and Their Institutions: From Grassroots Urbanism to Systemic Change

In the debate about smart cities, an alternative to a dominant top-down, tech-driven solutionist approach has arisen in examples of ‘civic hacking’. Hacking here refers to the playful, exploratory, collaborative and sometimes transgressive modes of operation found in various hacker cultures, this time constructively applied in the context of civics. It suggests a novel logic to organise urban society through social and digital media platforms, moving away from centralised urban planning towards a more inclusive process of city-making, creating new types of public spaces. This book takes this urban imaginary of a hackable city seriously, using hacking as a lens to explore examples of collaborative city-making enabled by digital media technologies. Five different perspectives are discussed. Hacking can be understood as (1) an ethos, a particular articulation of citizenship in the network era; (2) as a set of iterative and collaborative city-making practices, bringing out new roles and relations between citizens, (design) professionals and institutional actors; (3) a set of affordances of institutional structures that allow or discourage their appropriation; (4) a critical lens to bring in notions of democratic governance, power struggles and conflict of interests into the debate on collaborative city-making; and (5) a point of departure for action research. After a discussion of these themes, the various chapters in the book are briefly introduced. Taken together they contribute to a wider debate about practices of technology-enabled collaborative city-making, and the question how city hacking may mature from the tactical level of smart and often playful interventions to a strategic level of enduring impact.

The convenient city: smart urbanism for a resilient city

The surge of smart city technology, thinking, publications and consultancy offerings is significant. This implies there is something seriously developing. But to what extent is this a new development? In this paper the case will be made that urban design has always had to include new technologies and the smart city movement is just another wave of technology that demands inclusion in urban design practice. Nevertheless, city designers and policy makers should make use of the new possibilities on offering. Interactive urban environments could support healthy living, while smart and responsive regulators could minimize our energy use, and anticipative traffic management could help minimising congestion. Further to this, crowd-sensing could smoothen urban mobility and new forms of 3d-printing may re-use and reduce waste. The core of all new technological potential however is still to service people and to make life for urban citizens better. How could people in search for a convenient life be better serviced? Many of them want to have a nice house, a clean, safe and healthy environment, access to resources such as clean water, renewable energy and healthy food, a resilient place that is not vulnerable for all kinds of climate impacts and possibly some room for contemplation. With Maslow’s ladder in mind, achieving this not only depends on the availability and use of technology, rather a well-designed and integrated urban plan is asked for. Meeting the needs of contemporary urban citizens must be served by what urban design is supposed to deliver, only now with current available technologies in the back pocket. The paper emphasises how to design the convenient city by making use of the available technology, but it also takes a stand on the relativity of the current hype of smart cities.
