Conference Paper
Full-text available
Design optimization, as one of the major generative design methods, has been studied ever since the 1960s. However, half a century later, in an urban design context, it is still in the research and experimental phase and rarely employed in actual projects. This paper aims to reflect design optimisation methods through a comprehensive review from th...

Conference Paper
Full-text available
A common understanding exists that citizens should become more involved in the design, planning, and governance of the city. Due to a lack of common platforms and difficulties in the meaningful integration of the participatory input, however, the tools and methods currently employed in citizen engagement are often ill connected to the design and go...
Conference Paper

Collecting and analysing big data is beginning to change governance and societies worldwide. Not only is big data voluminous and complex in nature, but it also comes from a number of different sources, across different time frames and spatial scales. On the urban scale, we suggest that data-informed design, rather than data-driven design, is a bett...

The article proposes a method for teaching advanced urban design to working professionals in Singapore. The article aims to expand the discourse on parametric urban design education by introducing 'Urban Elements' as conceptual urban design instruments with an inherent rule-based logic, which can help to bridge gaps in teaching parametric urban des...
Article
This article is motivated by the fact that in Cape Town, South Africa, approximately 7.5 million people live in informal settlements and focuses on potential upgrading strategies for such sites. To this end, we developed a computational method for rapid urban design prototyping. The corresponding planning tool generates urban layouts including stre...

This paper will discuss the process of development and application of procedural methods in urban planning and design. Despite a lot of progress being made at architectural scale to consider a planning area as an integrated system of infrastructure, constructions, uses, socio-economic indices and many more, there is a gap in approaching larger urba...

In this paper, we present a method for generating fast conceptual urban design prototypes. We synthesize spatial configurations for street net- works, parcels and building volumes. Therefore, we address the problem of implementing custom data structures for these configurations and how the generation process can be controlled and parameterized. We...

Traditional urban design methods, still relying on the static and sectoral approaches, reach their limits to adapt themselves to the growing complexities and dynamics of modern cities. With the flourishing of artificial intelligence, a new approach called " cognitive design computing " has been proposed to utilize both the human creativity and comp...

Personal comfort is important in the design of objects and environments. However, as comfort is a subjective experience, it is a very difficult aspect to design for. This paper presents an interrogation into the design for human thermal comfort, in particular the design of personal devices for use in shared work environments. The findings of two us...
Conference Paper
The general notion of thermal comfort as provided by heating, ventilation and air conditioning systems (HVAC) in existing office buildings does not necessarily suit the needs and perceptions of the individual. This can result in a continuous source of discomfort and interpersonal dispute in shared work environments such as open plan offices. Our re...

The starting point of this study is the hypothesis that aesthetic judgements about two-dimensional layouts indirectly inform how functional aspects are evaluated. To test this assumption we investigated whether there is a connection between the topological property of the “intelligibility” of two-dimensional layouts and their aesthetic evaluation....

Project
Cognitive Urban Design Computing (CoDeC) is the title of a Principle Scientist project at the Austrian Institute of Technology (AIT) and of a work stream of the Big Data Informed Urban Design project at the Future Cities Lab (FCL) of the Singapore-ETH Center (SEC). With CoDeC we aim to develop a fu-ture-oriented computational design assistance system that is based on the human designer’s role. Its central aspect is the investigation of a productive combination of the excellence of human cognition with the power of modern computing technology. We call this approach “cognitive design computing”. The computational part aim to mimic the way a designer’s brain works by combining state-of-the-art optimi-zation and machine learning approaches with available simulation methods. The cognition part respects the complex nature of design problems by the provision of models for human-computation interaction. This means that a design problem is distributed between computer and designer.

This research project deals with the development of a creative evolutionary design methodology for layout problems in architecture and urban planning. To date many optimization techniques for layout problems have already been developed. The first attempts to automate layout were under-taken back in the early 1960s. Since then, these ideas have been taken forward in various differ-ent manifestations, for example shape grammars, CBS, cellular automata and evolutionary ap-proaches. These projects, however, are mostly restricted to very specific fields or neglect the creative, designerly component. Since pure optimization methods are of little practical use for design purposes, there have been no useful attempts to derive a universally applicable method for computer aided layout design. For this we need to be aware that designing is a process that occurs at different levels and degrees of abstraction. The solution space is explored in the realm between intuition and rationality in a variety of ways. Good solutions can only arise through an intensive and fluid dialogue between the designer and the generating system. The goal of this project is to develop an adaptive design system for layout problems. To this end we examine different approaches to achieving the best possible general applicability of such a system and discuss criteria that are crucial for the development of such systems.
