Sky high and back again : the evolution of simulation-based design from aerospace to construction

Emerging from the challenge to reduce energy consumption in buildings is a need for research and development into the more effective use of simulation as a decision-support tool. Despite significant research, persistent limitations in process and software inhibit the integration of energy simulation in early architectural design. This paper presents a green star case study to highlight the obstacles commonly encountered with current integration strategies. It then examines simulation-based design in the aerospace industry, which has overcome similar limitations. Finally, it proposes a design system based on this contrasting approach, coupling parametric modelling and energy simulation software for rapid and iterative performance assessment of early design options.

Closing the loop of design and analysis : Parametric modelling tools for early decision support

There is a growing need for parametric design software that communicates building performance feedback in early architectural exploration to support decision-making. This paper examines how the circuit of design and analysis process can be closed to provide active and concurrent feedback between architecture and services engineering domains. It presents the structure for an openly customisable design system that couples parametric modelling and energy analysis software to allow designers to assess the performance of early design iterations quickly. Finally, it discusses how user interactions with the system foster information exchanges that facilitate the sharing of design intelligence across disciplines.

A review of road traffic noise indicators and their correlation with the LA10(18hour)

This paper outlines a study to determine the correlation between the LA10(18hour) and other road traffic noise indicators. It is based on a database comprising of 404 measurement locations including 947 individual days of valid noise measurements across numerous circumstances taken between November 2001 and November 2007. This paper firstly discusses the need and constraints on the indicators and their nature of matching a suitable indicator to the various road traffic noise dynamical characteristics. The paper then presents a statistical analysis of the road traffic noise monitoring data, correlating various indicators with the LA10(18hour) statistical indicator and provides a comprehensive table of linear correlations. There is an extended analysis on relationships across the night time period. The paper concludes with a discussion on the findings.

Managing innovative change within organisations and project team environments

In an attempt to enhance the efficiency, productivity and competitiveness of today’s Architectural, Engineering, and Contractor (AEC) industry, this paper summarises the current status of an ongoing PhD research investigation in developing a sustainable AEC industry specific best-practice ‘Innovation-driven Change Framework’—more specifically a summation of the ‘fourth interrelated dynamic’ (culture). Leveraging off the outcomes of a two year industry and government supported Cooperative Research Centre for Construction Innovation (CRCCI) research project, as well as referring to recent internationally renowned case studies and related literature investigations, this research investigation includes further identifying, processing, analysing and categorizing various culture change methods, models, frameworks and processes utilized within the AEC and other industry sectors, and incorporating these findings in developing an AEC industry-specific ‘Innovation-driven Change Framework’

Beyond the walls of academia : architectural internships

A full architectural education typically involves five years of formal education and two years of practice experience under the supervision of a registered architect. In many architecture courses some of this period of internship can be taken either as a ‘year out’ between years of study, or during enrolment as credited study; work place learning or work integrated learning. This period of learning can be characterised as an internship in which the student, as an adult learner, is supervised by their employer. This is a highly authentic learning environment, but one in which the learner is both student and employee, and the architect is both teacher and employer; at times conflicting roles. While the educational advantages of such authentic practice experience are well recognised, there are also concerns about the quality and variability of such experiences. This paper reviews the current state of practice, with respect to architectural internships, and analyses such practice using Laurillard’s ‘conversational framework’ (2002). The framework highlights the interactions and affordances between teacher and student in the form of concepts, adaptations, reflections, actions and feedback. A review of common practice in architectural work place learning, internships in other fields of education, and focused research at the author’s own university, are discussed, then analysed for ‘affordances’ of learning. Such analysis shows both the potential of work place learning to offer a unique environment for learning, and the need to organise and construct such experiences in ways that facilitates learning.

Place and displacement : southeast Queensland architecture

The "vernacular" housing tradition of southeast Queensland is easily identifiable. Its history is more complex. This study seeks to challenge two popular conceptions of the "Queenslander" history by showing that they actually provide contradictory explanations. The aim is to produce a more complex account of local architecture and its historical explanation so that both its past and its present practices can be better understood as a distinctly subtropical idiom. This discussion shows that such practices may respond to common concerns but that are also ever-changing.

Green Exercise in the UK Countryside: Effects on Health and Psychological Well-being and Implications for Policy and Planning

There is evidence that contact with the natural environment and green space promotes good health. It is also well known that participation in regular physical activity generates physical and psychological health benefits. The authors have hypothesised that ‘green exercise’ will improve health and psychological well-being, yet few studies have quantified these effects. This study measured the effects of 10 green exercise case studies (including walking, cycling, horse-riding, fishing, canal-boating and conservation activities) in four regions of the UK on 263 participants. Even though these participants were generally an active and healthy group, it was found that green exercise led to a significant improvement in self-esteem and total mood disturbance (with anger-hostility, confusion-bewilderment, depression-dejection and tension-anxiety all improving post-activity). Self-esteem and mood were found not to be affected by the type, intensity or duration of the green exercise, as the results were similar for all 10 case studies. Thus all these activities generated mental health benefits, indicating the potential for a wider health and well-being dividend from green exercise. Green exercise thus has important implications for public and environmental health, and for a wide range of policy sectors.

Client intentions and Bruno Taut’s Glashaus

An often overlooked aspect concerning the Glashaus is the significant influence exerted by the client in the design of the building. In an intentional endeavour to create an exhibition pavilion that best showcased their glazed products and construction technologies, the German Luxfer Prism Syndicate both commissioned and majority financed the Glashaus. It would therefore seem strange that the official histories of the Glashaus would rather record the utopian, romanticised and arguably imagined intentions of Bruno Taut as the architect, as opposed to the reality of the client’s intentions. This paper offers a reinterpretation of the Glashaus from the perspective of German Luxfer Prism Syndicate. This reinterpretation is achieved through an investigation that primarily concentrates on the glazed areas of the Glashaus where the German Luxfer Prism Syndicates products were most evident. Using the arguments initially presented by Dietrich Neumann as a foundation, this research is additionally interwoven with inquiry into diverse aspects such as patents filed by the Luxfer group of companies and a close examination of the original black and white photographs of the Glashaus. A dramatically different understanding emerges when the Glashaus is argued from the perspective of the client; an understanding that is cold, hard and commercial as opposed to utopian and romanticised. As a result, this research makes a contribution to the current debate concerning the Glashaus and the re-evaluation of the histories of the modern movement.

Development and characterisation of tri- and tetra-nucleotide polymorphic microsatellite markers for skipjack tuna (Katsuwonus pelamis)

Skipjack tuna (katsuwonus pelamis) (SJT) is the largest tuna fishery in all the major oceans around the world, and the largest marine fishery in Sri Lanka. Knowledge of genetic population structure and effective population size of SJT in the Indian Ocean and other major oceans, however, is still lacking for better management practices and conservation strategies. We developed microsatellite genetic markers using SJT around Sri Lanka in the Indian Ocean, and characterise one tri- and seven tetra-nucleotide microsatellite loci isolated from enriched genomic libraries from SJT, to provide tools for addressing both conservation and fisheries management questions. An analysis of these eight microsatellite markers in two populations of SJT from eastern Sri Lanka (n = 44) and the Maldives Islands (n = 53) showed that all eight microsatellites were polymorphic with an average number of alleles per locus of 11.80 (range 5-27). Expected heterozygosities at marker loci ranged from 0.450 to 0.961. These markers are being used currently to characterise population structure and extent of natural gene flow in SJT populations from the eastern and western Indian Ocean. No significant linkage disequilibrium was detected among any loci pairs.

Collective equipments of power: The road and the city

A year ago, I became aware of the historical existence of the group CERFI— Le centre d’etudes, de recherches, et de formation institutionelles, or The Study Center for Institutional Research and Formation. CERFI emerged in 1967 under the hand of Lacanian psychiatrist and Trotskyite activist Félix Guattari, whose antonymous journal Recherches chronicled the group’s subversive experiences, experiments, and government-sponsored urban projects. It was a singularly bizarre meeting of the French bureaucracy with militant activist groups, the French intelligentsia, and architectural and planning practitioners at the close of the ‘60s. Nevertheless, CERFI’s analysis of the problems of society was undertaken precisely from the perspective of the state, and the Institute acknowledged a “deep complicity between the intellectual and statesman ... because the first critics of the State, are officials themselves!”1 CERFI developed out of FGERI (The Federation of Groups for Institutional Study and Research), started by Guattari two years earlier. While FGERI was created for the analysis of mental institutions stemming from Guattari’s work at La Borde, an experimental psychiatric clinic, CERFI marks the group’s shift toward urbanism—to the interrogation of the city itself. Not only a platform for radical debate on architecture and the city, CERFI was a direct agent in the development of urban planning schemata for new towns in France. 2 CERFI’s founding members were Guattari, the economist and urban theorist François Fourquet, feminist philosopher Liane Mozère, and urban planner and editor of Multitides Anne Querrien—Guattari’s close friend and collaborator. The architects Antoine Grumback, Alain Fabre, Macary, and Janine Joutel were also members, as well as urbanists Bruno Fortier, Rainier Hoddé, and Christian de Portzamparc. 3 CERFI was the quintessential social project of post-‘68 French urbanism. Located on the Far Left and openly opposed to the Communist Party, this Trotskyist cooperative was able to achieve what other institutions, according to Fourquet, with their “customary devices—the politburo, central committee, and the basic cells—had failed to do.”4 The decentralized institute recognized that any formal integration of the group was to “sign its own death warrant; so it embraced a skein of directors, entangled, forming knots, liquidating all at once, and spinning in an unknown direction, stopping short and returning back to another node.” Allergic to the very idea of “party,” CERFI was a creative project of free, hybrid-aesthetic blocs talking and acting together, whose goal was none other than the “transformation of the libidinal economy of the militant revolutionary.” The group believed that by recognizing and affirming a “group unconscious,” as well as their individual unconscious desires, they would be able to avoid the political stalemates and splinter groups of the traditional Left. CERFI thus situated itself “on the side of psychosis”—its confessed goal was to serve rather than repress the utter madness of the urban malaise, because it was only from this mad perspective on the ground that a properly social discourse on the city could be forged.

Architecture et révolution : Le Corbusier and the fascist revolution

In a letter to a close friend dated April 1922 Le Corbusier announced that he was to publish his first major book, Architecture et révolution, which would collect “a set ofarticles from L’EN.”1—L’Esprit nouveau, the revue jointly edited by him and painter Amédée Ozenfant, which ran from 1920 to 1925.2 A year later, Le Corbusier sketched a book cover design featuring “LE CORBUSIER - SAUGNIER,” the pseudonymic compound of Pierre Jeanneret and Ozenfant, above a square-framed single-point perspective of a square tunnel vanishing toward the horizon. Occupying the lower half of the frame was the book’s provisional title in large handwritten capital letters, ARCHITECTURE OU RÉVOLUTION, each word on a separate line, the “ou” a laconic inflection of Paul Laffitte’s proposed title, effected by Le Corbusier.3 Laffitte was one of two publishers Le Corbusier was courting between 1921 and 1922.4 An advertisement for the book, with the title finally settled upon, Vers une architecture, 5 was solicited for L’Esprit nouveau number 18. This was the original title conceived with Ozenfant, and had in fact already appeared in two earlier announcements.6 “Architecture ou révolution” was retained as the name of the book’s crucial and final chapter—the culmination of six chapters extracted from essays in L’Esprit nouveau. This chapter contained the most quoted passage in Vers une architecture, used by numerous scholars to adduce Le Corbusier’s political sentiment in 1923 to the extent of becoming axiomatic of his early political thought.7 Interestingly, it is the only chapter that was not published in L’Esprit nouveau, owing to a hiatus in the journal’s production from June 1922 to November 1923.8 An agitprop pamphlet was produced in 1922, after L’Esprit nouveau 11-12, advertising an imminent issue “Architecture ou révolution” with the famous warning: “the housing crisis will lead to the revolution. Worry about housing.”9

Toward a theory of the architectural subject

The extraordinary event, for Deleuze, is the object becoming subject – not in the manner of an abstract formulation, such as the substitution of one ideational representation for another but, rather, in the introduction of a vast, new, impersonal plane of subjectivity, populated by object processes and physical phenomena that in Deleuze’s discovery will be shown to constitute their own subjectivities. Deleuze’s polemic of subjectivity (the refusal of the Cartesian subject and the transcendental ego of Husserl) – long attempted by other thinkers – is unique precisely because it heralds the dawning of a new species of objecthood that will qualify as its own peculiar subjectivity. A survey of Deleuze’s early work on subjectivity, Empirisme et subjectivité (Deleuze 1953), Le Bergsonisme (Deleuze 1968), and Logique du sens (Deleuze 1969), brings the architectural reader into a peculiar confrontation with what Deleuze calls the ‘new transcendental field’, the field of subjectproducing effects, which for the philosopher takes the place of both the classical and modern subject. Deleuze’s theory of consciousness and perception is premised on the critique of Husserlian phenomenology; and ipso facto his question is an architectural problematic, even if the name ‘architecture’ is not invoked...

Architecture post mortem : the diastolic architecture of decline, dystopia, and death

Architecture Post Mortem surveys architecture’s encounter with death, decline, and ruination following late capitalism. As the world moves closer to an economic abyss that many perceive to be the death of capital, contraction and crisis are no longer mere phases of normal market fluctuations, but rather the irruption of the unconscious of ideology itself. Post mortem is that historical moment wherein architecture’s symbolic contract with capital is put on stage, naked to all. Architecture is not irrelevant to fiscal and political contagion as is commonly believed; it is the victim and penetrating analytical agent of the current crisis. As the very apparatus for modernity’s guilt and unfulfilled drives-modernity’s debt-architecture is that ideological element that functions as a master signifier of its own destruction, ordering all other signifiers and modes of signification beneath it. It is under these conditions that architecture theory has retreated to an “Alamo” of history, a final desert outpost where history has been asked to transcend itself. For architecture’s hoped-for utopia always involves an apocalypse. This timely collection of essays reformulates architecture’s relation to modernity via the operational death-drive: architecture is but a passage between life and death. This collection includes essays by Kazi K. Ashraf, David Bertolini, Simone Brott, Peggy Deamer, Didem Ekici, Paul Emmons, Donald Kunze, Todd McGowan, Gevork Hartoonian, Nadir Lahiji, Erika Naginski, and Dennis Maher. Contents: Introduction: ‘the way things are’, Donald Kunze; Driven into the public: the psychic constitution of space, Todd McGowan; Dead or alive in Joburg, Simone Brott; Building in-between the two deaths: a post mortem manifesto, Nadir Lahiji; Kant, Sade, ethics and architecture, David Bertolini; Post mortem: building deconstruction, Kazi K. Ashraf; The slow-fast architecture of love in the ruins, Donald Kunze; Progress: re-building the ruins of architecture, Gevork Hartoonian; Adrian Stokes: surface suicide, Peggy Deamer; A window to the soul: depth in the early modern section drawing, Paul Emmons; Preliminary thoughts on Piranesi and Vico, Erika Naginski; architectural asceticism and austerity, Didem Ekici; 900 miles to Paradise, and other afterlives of architecture, Dennis Maher; Index.

Does legal heritage affect obesity? The channel of motor vehicle dependence

We find a robust relationship between motor vehicle ownership, its interaction with legal heritage and obesity in OECD countries. Our estimates indicate that an increase of 100 motor vehicles per thousand residents is associated with about a 6% point increase in obesity in common law countries, whereas it has a much smaller or insignificant impact in civil law countries. These relations hold whether we examine trend data and simple correlations, or conduct cross-section or panel data regression analysis. Our results suggest that obesity rises with motor vehicle ownership in countries following a common law tradition where individual liberty is encouraged, whereas the link is small or statistically non-existent in countries with a civil law background where the rights of the individual tend to be circumscribed by the power of the state.

Daylighting design and simulation : ease of use analysis of digital tools for architects

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. Yet, there is still no consensus on how to assess what constitutes good daylighting design. Currently amongst building performance guidelines, Daylighting factors (DF) or minimum illuminance values are the standard; however, previous research has shown the shortcomings of these metrics. New computer software for daylighting analysis contains new more advanced metrics for daylighting (Climate Base Daylight Metrics-CBDM). Yet, these tools (new metrics or simulation tools) are not currently understood by architects and are not used within architectural firms in Australia. A survey of architectural firms in Brisbane showed the most relevant tools used by industry. The purpose of this paper is to assess and compare these computer simulation tools and new tools available architects and designers for daylighting. The tools are assessed in terms of their ease of use (e.g. previous knowledge required, complexity of geometry input, etc.), efficiency (e.g. speed, render capabilities, etc.) and outcomes (e.g. presentation of results, etc. The study shows tools that are most accessible for architects, are those that import a wide variety of files, or can be integrated into the current 3d modelling software or package. These software’s need to be able to calculate for point in times simulations, and annual analysis. There is a current need in these software solutions for an open source program able to read raw data (in the form of spreadsheets) and show that graphically within a 3D medium. Currently, development into plug-in based software’s are trying to solve this need through third party analysis, however some of these packages are heavily reliant and their host program. These programs however which allow dynamic daylighting simulation, which will make it easier to calculate accurate daylighting no matter which modelling platform the designer uses, while producing more tangible analysis today, without the need to process raw data.
