An artificial intelligence examination of the influence of geological conditions and changes in climate on damage to light structures in Victoria

Damage to light structures in the state of Victoria can be caused by movements of expansive soils. The presentation will present the results of an examination of reports of increasing complaints of house damage in Victoria and particularly in the Melbourne area. The examination analyses the influence of geology and change in climate using Neural Network and Genetic Algorithm approaches and assesses their relative importance in contributing to the cause of the damage.

Warrock collection: original line drawings by fourth year Deakin University architecture students of the Warrock Homestead, a local heritage listed property in Victoria

This collection includes the original line drawings by fourth year Deakin University architecture students of a well known local heritage listed property, the Warrock homestead. The Warrock homestead consisted of detailed original timber structures of the 19th century. The drawings are the result of a conservation project funded by the Commonwealth Government of Australia National Estate Grants program. In 1999 a further deposit of original reports relating to individual buildings on the property was received. The collection consists of monographs, photographs and photograph negatives, architectural drawings, VHS tapes and ephemera.

Cost performance of multi-rise structures in Australia

The article discusses the findings of research on the cost performance of structural frames. The analysis conducted is based on a range of designs that are commonly found in 10-storey buildings in Australia. The study explored the best cost solutions for any particular project through generic cost models of steel, concrete, and formwork systems used in commercial buildings. The research concluded that the most important factor in choosing structural building frames would be the unique characteristics of individual projects.

Examining and quantifying the drivers behind alterations and extensions to commercial buildings in a central business district

The drive to undertake building adaptation has increased in momentum, the primary reason being adaptation can be less expensive than new build and conventionally result in faster project delivery times. The issue of sustainable development is another clear driver for adaptation and collectively buildings contribute around half of all greenhouse gas emissions. At the same time governments seek effective and efficient ways of reducing the contribution of cities to climate change and building adaptation appears to offer a practical means of reducing building-related emissions. One example is the ‘1200 building program’ which aims to increase adaptation rates with a target of 1200 city centre office adaptations by 2020 as part of the strategy to achieve carbon neutrality. Through a longitudinal examination of building adaptations it is possible to identify the nature and extent of typical levels of adaptation, as well as determining the inter-relationship between different types of adaptation and building attributes. Melbourne city centre was used for a case study which analysed 5290 building adaptation events between 1998 and 2008. The findings promote the adaptive reuse of buildings in specific circumstances and are directly applicable for increasing sustainability in the built environment. The case study focused on existing buildings in a global city to ensure relevance to urban centres where existing commercial buildings can become part of the solution to mitigate climate change.

An energy-autonomous home in Melbourne - myth or reality?

Energy-autonomous buildings are possible. Completely energy self-sufficient houses can be found, for example, in Europe. If it is possible to cover the entire energy demand of a household from only renewable energy generated on site in a central European climate, what is required in a temperate climate, typical of southern Australia? This paper describes an investigation to broadly assess the technical, practical and financial feasibility of energy-autonomy for a hypothetical suburban house in Melbourne, Victoria. The findings firstly demonstrate the importance of reducing energy demand by using passive solar building strategies and energy efficient appliances to reduce demand to a reasonable level. The paper then discusses four scenarios and combinations of technologies to meet this reduced demand. The three scenarios which give energy autonomy increase the capital cost of a typical house by between 15% and 3%, and there would be insufficient roof area to accommodate the solar technologies required in two of the scenarios investigated. It is therefore concluded that while the goal of energy autonomy is technically feasible, it is not likely to be financially or practically acceptable. A fourth scenario of an energy-exporting house was also investigated and is shown to be a much more attractive option.

Optimising the life cycle energy performance of residential buildings

A holistic approach to low-energy building design is essential to ensure that any efficiency improvement strategies provide a net energy benefit over the life of the building. Previous work by the authors has established a model for informing low-energy building design based on a comparison of the life cycle energy demand associated with a broad range of building assemblies. This model ranks assemblies based on their combined initial and recurrent embodied energy and operational energy demand. The current study applies this model to an actual residential building in order to demonstrate the application of the model for optimising a building’s life cycle energy performance. The aim of this study was to demonstrate how the availability of comparable energy performance information at the building design stage can be used to better optimise a building’s energy performance. The life cycle energy demand of the case study building, located in the temperate climate of Melbourne, Australia, was quantified using a comprehensive embodied energy assessment technique and TRNSYS thermal energy simulation software. The building was then modelled with variations to its external assemblies in an attempt to optimise its life cycle energy performance. The alternative assemblies chosen were those shown through the author’s previous modelling to result in the lowest life cycle energy demand for each building element. The best performing assemblies for each of the main external building elements were then combined into a best-case scenario to quantify the potential life cycle energy savings possible compared to the original building. The study showed that significant life cycle energy savings are possible through the modelling of individual building elements for the case study building. While these findings relate to a very specific case, this study demonstrates the application of a model for optimising building life cycle energy performance that may be applied more broadly during early-stage building design to optimise life cycle energy performance.

Post-war migrant built heritage in Melbourne : from assimilation to multiculturalism

If place identities are created by ascribing subjective meaning to sites and buildings it follows that diverse groups will consider place meaning differently. This poses a challenge for the selection and interpretation of heritage sites in plural societies where notions of architectural significance are likely to conflict. Basing heritage policy on the premise of a shared heritage is particularly challenging when the cultural traditions of the past underlie definitions of architectural significance in a more culturally diverse present. This paper presents an introduction to research exploring the inclusion of twentieth century migrant built heritage in Australia. Through selected examples of recently recognised heritage sites in Melbourne, the paper considers how migrant heritage is included and what this reveals about the cultural traditions underlying Australian heritage discourses. The inclusion of migrant places suggests that there is an initial shift in heritage discourses where notions of architectural significance have expanded to include the history of post-war migration. However, the examples raise questions about the nature of cultural inclusivity in heritage frameworks.

The influence of climate change on Thorthwaite moisture index on the design of light structures

Significant long term changes in the earth’s climate have occurred in the past but recently there has been more severe climate fluctuation than have occurred in the past few centuries. The effect of this climate change on the foundation conditions of roads and low-rise buildings is costing several hundred billion dollars world-wide. A method which tracks this climate change will be of great value for companies and governments. C.W. Thornthwaite (1948) defined the Thornthwaite Moisture Index (TMI) as the first base for his climate classification system and mapping in the United States. There are 3 important factors to predict ground movement: (a) the degree of moisture index change (b) the depth at which this change occurs and (c) the foundation soil type. The water budget model was used by Thornthwaite (1948) to calculate the moisture index. This paper also discusses two typical examples of the use of this model. Originally TMI’s were mainly used to map soil moisture conditions for agriculture but soon became a method to predict environmental and pavement foundation changes.

RAN-Vic : renal access nurses of Victoria unite.

The Renal Access Nurse has recently become an integral member of the renal health care team in Australia. Research has shown that the introduction of a Renal Access Nurse into dialysis units enhances the referral process for new access, improves survival rates, and success of access creation. Australia has been relatively slow in the introduction of the role of the Renal Access Nurse. The USA, UK and Europe have been utilising Renal Access Nurses in renal units for many years and their roles are firmly entrenched.

The first Renal Access Nurse was introduced in Victoria in 2003, increasing to 7 in 2007. It was evident in 2006 that a networking system for Renal Access Nurses was needed in Victoria, so RAN-Vic was born.

RAN-Vic consists of 6 Renal Access Nurses from the major hubs in Melbourne and Geelong, thus covering a large part of the Victorian dialysis community through satellite units throughout the state.

The group meet quarterly, with the main goals being to network, share ideas, support each other with challenges arising from the new role, benchmark, undertake quality initiatives and education of renal nursing staff. By doing this, we hope to improve outcomes for patients, improve work practices pertaining to renal access, and further redefine the new role.

RAN-Vic is the first of its kind in Australia, providing care for renal access for the dialysis population throughout Victoria. We recommend for all states in Australia to consider forming a Renal Access Group to help improve renal access outcomes.

Narrating heritage's living stories : a comparative study of China's Suojia ecomuseum and Australia's Melbourne living museum of the West

The Ecomusée, as emerged in France in the 1970s, is a form of open-air museum that aims to maintain collections in their original environments with local communities serving as curators and managing their own heritage. This approach and philosophy implies and is dependent upon democratic principles in the conservation and interpretation processes. Since the 1990s, China has adopted the ecomusée concept for the conservation of selected ethnic villages to relieve tensions between poverty and heritage conservation. However, does this concept really work in China? To answer this question, the Suojia Ecomuseum, the first such initiative - has been selected as a case study and assessed using the mixed methodologies of on-site observation, documentation and semistructured interviews. This process has identified several issues and problems associated with this ecomuseum. It demonstrates that Suojia Ecomuseum has not achieved international benchmarks, neither philosophical nor practical expectations have been met. This conclusion challenges the internationally acknowledged notion that all ecomuseums develop and are operated using a bottom-up approach, that they were all community-based and democratic. These discrepancies lead to other questions about the differences between ecomuseums in China and elsewhere. In order to map and compare the differences between ecomuseums in China and in Western democracies, a detailed survey was undertaken using Melbourne’s Living Museum of the West, Australia. Applying the same methodologies as in China, a comparable examination was undertaken as to its background, objectives, management structures, programs and activities, and project outcomes as well as problems. The differences between Suojia Ecomuseum and Melbourne’s Living Museum are then explained and shown. They demonstrate quite diverse organisations with different objectives and management structures relating to different cultural and natural resources. However, the unexpected finding was that the futures of both ecomuseums relied on the financial support and passion of younger generations and hence were vulnerable.

Damage identification of slab–girder structures: experimental studies

Slab–girder structures composed of steel girder and reinforced concrete slab are widely used in buildings and bridges in the world. Their advantages are largely based on the composite action through the shear connection between slab and girder. In order to assess the integrity of this kind of structures, numerous vibration-based damage identification methods have been proposed. In this study, a scaled composite slab–girder model was constructed in the laboratory. Some removable shear connectors were specially designed and fabricated to connect the girder and slab that were cast separately. Then, a two-stage experiment including both static and vibration tests was performed. In the first stage, vibration tests were conducted under different damage scenarios, where a certain number of shear connectors at certain locations were removed step by step. In the second stage, two sets of hydraulic loading equipment were used to apply four-point static loads in the test. The loads are increased gradually until concrete slab cracked. The loading histories as well as deflections at different points of the beam are recorded. Vibration test was carried out before and after concrete cracking. Experimental results show that the changes of mode shapes and relative displacement between slab and girder may be two promising parameters for damage identification of slab–girder structures.

Being a ‘wog’ in Melbourne – young people's self-fashioning through discourses of racism

The Greek community in Melbourne, Australia, is large and has a long history in the city. It is diverse and associated with a range of cultural, social and political structures. It has strong transnational links and in many ways exemplifies ‘diasporic’ in contradistinction to ‘migrant’. This paper focuses on young people from this community, particularly those who attend schools established to promote Greek language and cultural maintenance. In this paper, we examine such students’ explorations of their cultural identifications, most specifically how they adopt the term ‘wog’. This term is complex and its place in Australian discourse has shifted over time. Tracking these shifts and considering them as a context for these young people's use of the term allows us to consider the processes involved in their self-fashioning. We argue that their uptake of ‘wog’ involves the deployment of irony, given their awareness of its strong association with racism. We are also interested in the potential for women's experience to be silenced through the common association between ‘wog’ and protest masculinities. We argue that these students’ use of the term illustrates self-fashioning that provides insights into the complexities that surround cultural identification at the micro level, including schooling, but also in the broader context of globalisation.
