Approximating the evacuation of the World Trade Center North Tower using computer simulation

This article concerns an investigation of the full scale evacuation of a building with a configuration similar to that of the World Trade Center (WTC) North Tower using computer simulation. A range of evacuation scenarios is explored in order to better understand the evacuation of the WTC on 11 September 2001. The analysis makes use of response time data derived from a study of published WTC survivor accounts. Geometric details of the building are obtained from architects' plans while the total building population used in the scenarios is based on estimates produced by the National Institute of Standards and Technology formal investigation into the evacuation. This paper attempts to approximate the events of 11 September 2001 and pursue several `what if' questions concerning the evacuation. In particular, the study explores the likely outcome had a single staircase survived intact from top to bottom. More generally, this paper explores issues associated with the practical limits of building size that can be expected to be efficiently evacuated using stairs alone.

[Organiser of Stirling's Red Buildings Conference for the Twentieth Century Society]

The aim of the conference is to review the three 'Red Buildings' with experts who have studied their history and their performance, and to discuss their future. Work is due to take place on the Leicester and Oxford buildings in the relatively near future, and technical knowledge can be shared in a context of understanding the design intention. Also to celebrate Stirling and Gowan's careers from a broader perspective and to assert the value of looking after these special buildings as assets for the future. The speakers in the afternoon session are people who knew the two architects well, and in some cases worked for them. [From University of Leicester]

Grid effects

Zaha Hadid's Kartal Pendik Masterplan (2006) for a new city centre on the east bank of Istanbul proposes the redevelopment of an abandoned industrial site located in a crucial infrastructural node between Europe and Asia as a connecting system between the neighbouring areas of Kartal in the west and Pendik in the east. The project is organised on what its architects call a soft grid, a flexible and adaptable grid that allows it to articulate connections and differences of form, density and use within the same spatial structure [1]. Its final overall design constitutes only one of the many possible configurations that the project may take in response to the demands of the different areas included in the masterplan, and is produced from a script that is able to generate both built volumes and open spaces, skyscrapers as well as parks. The soft grid in fact produces a ‘becoming’ rather than a finite and definitive form: its surface space does not look like a grid, but is derived from a grid operation which is best explained by the project presentation in video animation. The grid here is a process of ‘gridding’, enacted according to ancient choreographed linear movements of measuring, defining, adjusting, reconnecting spaces through an articulated surface rather than superimposed on an ignored given like an indifferent colonising carpet.

Giovanni Battista Montano as Architectural Draughtsman: Recording the Past and Designing the Future

Giovanni Battista Montano (1534-1621), who was born in Milan and trained as a woodcarver, relocated permanently to Rome in the early 1570s where his interest in sculpting was replaced by intense study of the city’s antique monuments and ruins. Although Montano carried out several sculptural and architectural projects during his time in Rome, it is his surviving corpus of drawings that testifies to his passion of exploring ancient architecture through the medium of drawing. While Montano was not famous during his lifetime, a large body of his intriguing designs became celebrated and widely circulated after his death thanks to the 1624 publication of Montano’s designs by his loyal pupil, Giovanni Battista Soria. Montano’s lifelong work differs from virtually all of his predecessors and contemporaries in its “fantastical” and ornamental nature. This thesis explores Montano’s artistic training as it relates to his later interest in imaginatively reconstructing antique buildings, along with his disregard for archaeological or historical accuracy. The subject matter upon which Montano focused is discussed, along with his objective in creating a large corpus of half-historical, half-invented drawings. His drawing techniques are explored with specific reference to the largest group of extant Montano drawings, today housed in Sir John Soane’s Museum, London, England, and also in reference to three original Montano drawings in the Centre Canadien d’Architecture/Canadian Centre for Architecture, Montréal. Also explored is the legacy and impact of Montano’s drawings and the later publications of his designs on the works of Roman Baroque architects, specifically Borromini and Bernini. This thesis ultimately attempts to understand the impact of the intellectual and artistic environment surrounding Montano in late sixteenth and early seventeenth century Rome, his drawing techniques, his choice of subject matter, and the reception that his unique works received from contemporary artists and intellectuals, along with those of the following generation.

The Changing Significance of European Borders

It is necessary to understand how state borders in Europe are changing in order to fully assess the factors which facilitate and encourage cross-border cooperation. This article considers the enduring social significance of borders, the need for a historical understanding of the nature and extent of border change in Europe, and the impact of recent European integration. Change in the structure, functions and meanings of European state borders has been the norm rather than the exception. Although much of this change has been associated with war, violence and coercion, a key contemporary issue facing the architects of European integration is how the ambiguity and contradictory nature border change can be regulated democratically and managed cooperatively.

Designs and designers of medieval ‘new towns’ in Wales

Medieval 'new towns' seem to echo Roman towns in having a grid of streets associated with a fortress, and have often been credited with a standard plan applied by the hand of authority. Here the authors analyse the new towns founded by Edward I in Wales and find some highly significant variations. Rediscovering the original layouts by high precision survey and GIS mapping, they show that some towns, founded at the same time and on similar topography, had quite different layouts, while others, founded at long intervals, had plans that were almost identical. Documentation hints at the explanation: it was the architects, masons and ditch-diggers, not the king and aristocracy, who established and developed these blueprints of urban life.

Post-Occupancy Evaluation: Purpose, Benefits and Barriers

This paper explores the historical development of POE in order to provide a contextual backdrop to current discussions. This review provides a much needed discussion on the benefits and barriers facing POE which should enable designers, facility managers and building users to appreciate the value and purpose of this important building evaluation process. The paper will encourage architects and building owners to conduct POEs to benefit all stakeholders and future designs. This is an international peer reviewed journal.

Creative Activism: a pedagogical and research tool

Environmental activism has a long history in protest, addressing issues of degradation and segregation that threaten existing ecologies, social and built fabrics. Environmental activism is traditionally understood as a reaction, chiefly by groups of people, against a perceived external threat. In the 60’s and 70’s, an activist stance began to emerge in the work of some artists and architects, who used creative methods such as performances, happenings, temporary spatial interventions etc to convey their political/aesthetic messages. Some of this work engaged directly with communities but predominantly it was the production of one individual working ‘outside’ society. However such actions demonstrated not only the power of the visual in conveying a political message but also the potential of conceptual creative approaches to reveal alternative values and hidden potentials. This marked a shift from activism as protestation towards an activism of reconceptualisation. Recently, activist groups have developed a more politically informed process. Whilst their ‘tools’ may resemble work from the 60’s and 70’s , their methodologies are non-traditional, ’rhizomatic’, pedagogical and fluid; working alongside, rather than against, the established power and funding structures. Such creative processes build new, often unexpected, stakeholder networks; offer neutral spaces in which contentious issues can be faced; and create better understanding of values and identities. They can also lead to permanent improvements and development in the physical fabric. This paper will discuss a pedagogical example of activism in architectural education. The event (www.fourdaysontheoutside.com) is in its fifth year of existence and as such has revealed a value and impulse beyond its learning and teaching value. The paper will discuss how the event contributes to the university’s outreach programme and how its structure acts as a seedbed for potential research projects and partnerships. UK Universities talk extensively about applied research but have few actual strategies by which to generate it. Fourdaysontheoutside offers some potential ways forward.
