Collaborative Design: Combining Computer-Aided Geometry Design and Building Information Modelling

The spatial expression and ordering of social processes is one of the primary aims of architecture. Such is the view of Zaha Hadid Architects (ZHA), where Shajay Bhooshan heads the computation and design group (CoDe). Here he explains how the practice has followed in the footsteps of the automotive, aircraft and shipbuilding industries in adopting a hybrid approach to design development. As demonstrated by a mathematics-themed gallery conceived by ZHA for London's Science Museum, it assimilates historical knowledge while facilitating fabrication and allowing for future flexibility.

The Role of Additive Manufacturing and Physiomimetic Computational Design for Digital Construction

The recent adoption of the term additive manufacturing (AM) to describe a broad range of digital ‘layer by layer’ fabrication techniques comes 20 years since its inception and more than 10 years since architectural practices engaged with the technology for making prototypes and models. Soon this technology will join existing CNC subtractive and formative processes within the volume and mass-market sectors, where design complexity and increased functionality result in competitive advantage. It is also about a decade since researchers proposed additive manufacturing for construction. Rupert Soar and David Andreen introduce here the different construction-scale additive manufacturing systems currently in development. If linked to physiomimetic computational design strategies, these technologies provide novel possibilities for addressing architecture's manufacturing challenges in the face of energy expenditure, material resources and environmental impact.

Green Footstep: A Tool for Evaluating a Building's Life-Cycle Carbon Footprint and Informing Carbon Decisions During the Building Design Process

The Green Footstep model provides a valuable set of metrics for ecodesign and masterplanning. Here Michael Bendewald and Victor Olgyay of the Rocky Mountain Institute (RMI), with Ken Yeang , describe the significance of this new online tool. In addition to supplying the basis for balancing the built environment's engineering systems, the Green Footstep enables efficiency with the use of renewable energy systems, such as photovoltaics (illustrated here). By presenting the critical case for increasing the percentage of new vegetation and trees in new developments, it enhances local biodiversity. Carbon emissions are offset from: on-site clearance of vegetation, the disturbance of the many constituents of the local ecosystem and the removal of organic rich soil by new construction.

On Modelling Complexity and Urban Form

As generators of new cities or extensions of existing ones, algorithmic urban models provide a means of designing urban forms of a new complexity. They have the capacity to produce extremely intricate architectural forms, but also to be responsive to scenarios and constraints. M Christine Boyer , the William R Kenan Jr Professor of Architecture at Princeton University, reflects on how ‘architects acting as an interface between data sets and computer algorithms’ might shape distinctive urban environments that lead to the mass customisation of cities.     

The Future of Information Modelling and the End of Theory: Less is Limited,More is Different

The computational design strategist Cynthia Ottchen , who was previously Head of Research and Innovation at OMA, offers insights into the future of building information modelling (BIM). Now in the Petabyte Age of the data deluge, she argues that in our adoption of BIM we have to surpass mere data collection and technical optimisation and open up new ways of thinking with the creative use of ‘soft data’.

To a Curator of Beautiful and Healthy Lives: A Note to Myself

How might architectural thinking and processes shift over the next 35 years? How might the architect's role be redefined with shifting ethical values? Could the architect be viewed as less of a design professional and more of a curator engaged in the development of healthy holistic environments, catering for all of society's needs? DaeWha Kang , an architect from 2050, writes to his earlier self, critiquing the work that he undertook in independent practice and as a design director at Zaha Hadid Architects in the mid-2010s. He describes how his design methodologies have evolved in the intervening years.     

Changing Building Sites: Industrialisation and Automation of the Building Process

The introduction of robotics in construction is part of a much longer history of industrialisation and automation on the building site. Thomas Bock of the Technical University of Munich and Silke Langenberg of the University of Applied Sciences, Munich, highlight how the Industrial Revolution and the development of a transport infrastructure in the 18th and 19th centuries in Europe first triggered the shift in the building trade from a largely localised industry into a national and mechanised one, leading to the highly advanced automated construction techniques that continue to be developed in Japan and other Asian countries to this day.     

Four Decades of Open Building Implementation: Realising Individual Agency in Architectural Infrastructures Designed to Last

The ‘open building’ approach grew out of research and early projects starting in the 1960s, aimed at overcoming the rigidity of the prevailing top-down housing process in the Netherlands. Geared to ensuring user control and sustainability in the built stock, it involves coordinating stakeholders in the real estate development process, enabling variety and change to become efficient. Architect, researcher and educator Stephen Kendall explains the approach and describes pioneering projects in Europe, Japan, China, the US and Russia, as well as detailing instances around the world where it has become part of public policy.     

Intelligent Cities and the Taxonomy of Cognitive Scales

Here, Guest-Editor Michael Weinstock with Mehran Gharleghi of the EmTech programme at the Architectural Association (AA) School of Architecture in London shift the definition of the intelligent city away from one that is predicated on information and communication technologies towards a deeper and more profound characterisation. They explore the possibilities of cognitive complexity in urbanism emerging out of the interaction of sensory processing and behavioural responses to the world. Within the context of large infrastructural systems, what might, for instance, rapidly developing machine consciousness have in common with collective intelligence? What could the preliminary conceptual schema be for an intelligent city that is sufficiently self-aware to synchronise its systems with climatic and ecological phenomena at regional and local scales?     

Material,Form and Force

Conventionally, material in architecture has been treated as the ‘servant’ of form. An iterative design process, though, that continuously integrates material, form and force has the potential to unfold a new generative logic of form-finding. This offers ways of processing the flow of forces through a material object and balancing variations of form with the organisation and behaviour of material. Toni Kotnik and Michael Weinstock present a series of experimental construction projects, developed within the Emergent Technologies and Design (EmTech) programme at the Architectural Association (AA) in London, that explore the intricate relationship between material, form and force.

Peak Oil and Transition Towns

If economic growth is only possible with the availability of cheap energy, what happens as production of oil peaks, and petroleum extraction declines? Rob Hopkins , an activist behind the Transition movement, argues for a new bottom-up approach to economic development that is also more localised and nourishing. Shifting the emphasis from sustainability towards resilience, he seeks a rethinking of the way local communities feed, house and power themselves.     

Fast Forwards: 10 Years of Sustainable Initiatives in the Gulf Region

Over the last decade, sustainable initiatives have proliferated in the UAE through a disparate range of public and private sector efforts. Jeffrey Willis , Sustainability Leader for Arup in the Gulf, provides a comprehensive review of these enterprises, highlighting how momentum has been clustered in three distinct periods of activity: previous to 2006 ; 2006 to 2008 ; and then since the global financial crisis in 2008.     

Versatility and Vicissitude: An Introduction to Performance in Morpho-Ecological Design

The dictionary explanation of ‘performance’ is to ‘carry out an action’ or ‘to fulfil a task’. Invariably, this definition seems to invoke a tired utilitarian debate on the correlation between form and function. Here, Michael Hensel and Achim Menges explain how in this issue of AD they aim to move the debate on entirely. In so doing, they redefine form not as the shape of a material object alone, but as the multitude of effects, the milieu of conditions, modulations and microclimates that emanate from the exchange of an object with its specific environment – a dynamic relationship that is both perceived and interacted with by a subject. Performance evolves from the synthesis of this dynamic, while morpho-ecological design concerns an instrumental approach, making form and function less of a dualism and more of a synergy that aspires to integral design solutions and an alternative model for sustainability.

Disarmed Strategies: New Machines and Techniques for an Era of Computational Contextualism in Architecture

Digital fabrication to date has typically been blind to context. But this need not be the case – as demonstrated by the experiments of Gramazio Kohler Research , based at ETH Zurich. They have developed systems that employ robotic arms and flying machines with feedback control to adapt the fabrication process as it progresses. From the ballistic projection of clay in a cutting-edge version of adobe, to the interlacing of string to form suspended structures in space, Fabio Gramazio, Matthias Kohler and Hannes Mayer outline some of their inventions here.     

Cities and Grids: In Search of New Paradigms

The wider global influences of expanded populations, new technologies and economies in both Europe and the Far East are having a direct impact on the pattern and planning of urban form. Joan Busquets , the principal of B Arquitectura I Urbanisme (BAU) in Barcelona, and Professor in Practice of Urban Planning and Design at Harvard Graduate School of Design (GSD), describes how the urban grid is continuing to evolve with these changes, becoming ‘a matrix for innovation within urban development, allowing the creation of sustainable and compact cities’, enabling the forming of ‘new networks and innovative city systems’.     

The Future is Unwritten: Global Culture,Identity and Economy

Is architecture no more than a mere handmaid to global capitalism and the international property market? Murray Fraser , Professor of Architecture and Global Culture at the Bartlett School of Architecture, UCL, asserts that the true picture is both much more complex and less homogeneous than it might appear. While acknowledging that economic conditions are significant drivers in architecture, he argues that it is still possible for designers to respond creatively with suppleness and foresight in their exploration of paths for a better future.     

‘Never Mind All That Environmental Rubbish,Get On With Your Architecture’

Could the primacy of green architecture in recent years be eroding the discipline? Is it reducing architecture to a mere ‘environmental techno-science’? Penelope Dean argues for a revised environmental agenda that is driven by ideas and concepts rather than subservient technologies. Copyright © 2009 John Wiley & Sons, Ltd.
