Towards solutions for a liveable future: progress, practice, performance, people: Proceedings of the 41st Annual Conference of the Architectural Science Association ANZAScA

There is hope! Since Al Gore disclosed the inconvenient truth, the climate has changed. The time of denial is over; the era of well-informed action and sound development is with us. Sustainability has now moved from the fringe, into the mainstream of politics, society, architecture and building practice. In this new context architectural science will contribute to two main tasks: prevent further damage to our environment, and respond to challenges invoked by climate change.
The built environment and human activity within it account for a large part of the problem. Architectural science and architectural practice are part of the solution. The ANZAScA 2007 conference focuses on the solutions architectural science has to offer toward a liveable future through the following generic themes:
progress – the evaluation and improvement of built facilities, new and existing, in terms of energy intensity, financial reward and environmental impact.
practice – the relationship between our cultural heritage, new facility design, retrofit design and its realisation
through construction.
performance – the connection between building operation targets, validation of performance, and user comfort and interaction in new and existing environments.
people – the effect of space on user behaviour, user responsibility and social wealth.
In response to this challenge, architectural science researchers including students, educators, and practitioners at ANZAScA 2007, present a broad range of research activity and concern within the built environment from global issues down to the specific actions of individuals.

Urban growth centres on the periphery : ad hoc policy vision and research neglect

The focus of this paper is peripheral urban growth centres on the edges of capital cities in Australia and the challenges they face as dormitory suburbs attempting to establish their own local business development. These challenges create dilemmas as infrastructure and climate change place pressure on long commuting times, while developing strong locally based communities is limited by many resource and demand constraints. The main research question is to examine how these challenges are being addressed in both public policy and academic research. Two propositions emerge from this analysis. The first is that, despite clear recognition of these challenges by public policy makers, there is a lack of coherent policy vision in addressing the dilemmas that are facing these urban growth centres. The second is that, despite all the concerns and lack of policy vision, there is a dearth of useful academic research in Australia to understand the dilemmas and provide guidance for appropriate policy options. In the context of ad hoc policy and academic neglect; Casey, Melton and Wyndham are the three major urban peripheral local government areas in Victoria that are profiled in this paper. They serve as examples in examining incoherence of policy and then analysing the elements that are needed for effective and strong peripheral growth centres that could propel these centres towards efficient and equitable liveable communities. A broad composite model of regional economic development is used to examine the attendant problems in these urban centres and the various viable policy options for addressing these problems. In the process, this paper aims to provide a basis for further rigorous academic investigation of peripheral urban growth centres in Australia and, arising from this, more coherent policies for the economic development of such centres.

Tale of three (media) cities

In the early years of the twenty-first century, three of the 23 Arab nations – Jordan, the United Arab Emirates and Egypt – have established media cities in the hope that media and knowledge-based industries will push their economies forward. All three cities are the direct result of government policy and planning. The intention is that a combination of media, business, technology and finance will become inexorably linked and that the resulting synergy will produce thousands of jobs. The cities offer financial benefits to companies located in the special zones created for the cities. As well as generating jobs and leapfrogging their economies into the 21st century, these cities are also meant to be shining symbols of modernity in societies that have tended to look backwards rather than forwards. This paper considers the vision behind these cities, who owns them, the business models employed and their likelihood of success. It also considers the key issue of freedom of expression and the free flow of information in these cities, in the context of societies that traditionally have restricted the flow of information and adopted a different interpretation of freedom of expression, compared with the West’s approach.

Identifying house price diffusion patterns among Australian state capital cities

Prior research supports the proposition that house price diffusion shows a ripple effect along the spatial dimension. That is, house price changes in one region would reflect in subsequent house price changes in other regions, showing certain linkages among regions. Using the vector autoregression model and the impulse response function, this study investigates house price diffusion among Australia's state capital cities, examining the response of one market to the innovation of other markets and determining the lagged terms for the maximum absolute value of the other markets' responses. The results show that the most important subnational markets in Australia do not point to Sydney, rather towards Canberra and Hobart, while the Darwin market plays a role of buffer. The safest markets are Sydney and Melbourne. This study helps to predict house price movement trends in eight capital cities.

Problems and solutions on land reservation system of small and medium-sized cities in China

Based on the analysis of the basic principal of land reservation system of small and medium-sized cities, this paper gives detailed discuss on many problems which exist during the process of land reservation system, such as unclear function position of land reservation organization, single capital resource, unfair land compensation standard and incomplete urban design. It also submits the proposal—choosing one scientific model, establishing suitable organization, opening more channels for raising funds, and setting up reasonable land compensation standard to unify the land reservation in small and medium-sized cities, improve the efficacy of reserve departments, adjust and standardize the land market in order to promote the healthy development of small and medium-sized cities in the long term.

Architecture, multiculturalism and cultural sustainability in Australian cities

The way that the built environment represents and accommodates people of different cultures is an important facet of developing a holistically sustainable future. Architecture intervenes, maps and signifies and in doing so it constructs identities. It helps to shape how we know the world by mediating power, social relations and cultural values. Events such as the settlement, inhabitation and establishment of diasporic communities involve the occupation of space. Architecture provides the armature of this space, its form and its image. Building is a potent means by which identity can be formed. A most significant part of people’s well-being and capacity is their participation in literally building communities. This paper will illustrate this issue through discussion of contemporary Australian cities. The buildings of a wide variety of immigrants to Australia have since the 1950s contributed greatly to the changing nature of its cities. They are the physical manifestation of the great demographic changes that have occurred across the nation during this period. The combination of people of different backgrounds and cultures lends a unique quality to Australian built environments, and this needs not only be understood but celebrated, as they are contributing to the development of Australian urban culture. Increased knowledge and understanding of the impact of immigration and multiculturalism on our built environment will add substantially to understanding of the diversity of Australia’s cultural heritage, and the potential of future planners, architects, and members of the general public to create inclusive and dynamic Australian cities.

Evidence for healthy cities : reflections on practice, method and theory

The European Healthy Cities project can be characterized as a social movement that employs an extremely wide range of political, social and behavioural interventions for the development and sustenance of urban population health. At all of these levels, the movement is inspired by ideological, theoretical and evidence-based perspectives. The result of this stance is a dynamic, complex and diverse landscape of initiatives, plans, programmes and actions. In quantitative terms (the number of WHO designated cities and associated cities and communities through national networks), ‘Healthy Cities’ can be regarded as an extraordinary accomplishment and a credit for both WHO and cities in the movement. In qualitative terms, however, critics of the movement have maintained that little evidence on its success and effectiveness has been generated. This critique finds its foundations in the mere perceptions of evidence, the politics of science and urban governance, and perspectives on the preferred or professed utilities of evidence-based health notions. The article reviews the nature of evidence and its interface with politics and governance. Applying a conceptual framework combining insights from knowledge utilization theory, theoretical perspectives on (health) policy development, theory-based evaluations and planned intervention approaches, it demonstrates that, although the evidence is overwhelming, there are barriers to the implementation of such evidence that should be further addressed by ‘Healthy Cities’.
