Improving comfort levels in Darwin houses through passive design

Darwin`s climate is hot and humid and as a result the use of residential air-conditioners is high. Although this technology allows the occupant to achieve thermal comfort, its use contributes directly to an increase in the emission of greenhouse gases. More environmentally-friendly ways of achieving residential thermal comfort in this climate need to be investigated. One method is to improve the home`s passive design. The aim of this research was to increase the thermal comfort of typical Darwin homes without the use of air conditioning. Temperature data from two houses (lightweight elevated and concrete) was recorded over a nine-day period and used to validate a TRNSYS simulation model of each house. Simulations were run using these validated models and three months of climatic data (January—March) to evaluate various passive design strategies. The success of three strategies was analysed using PMV and PPD indicators. As a single strategy, it was found that ventilation and air velocity by far increased the level of thermal comfort for occupants of both houses. Although the passive design strategies of increased shading and insulation were beneficial, Darwin`s ovemight low temperature and humidity are still too high to reduce these levels within the house significantly without air conditioning.

Space : the final frontier : festivals, community and place in Darwin Northern Territory, Australia

The ethnographies of two festive public events are used to analyse some aspects of community and place in Darwin, Northern Territory, Australia. Place entails layers of physical and imaginal geographies and involves local and extra-local factors. Discourses about place among those who lived in Darwin are interwoven with discourses about community. A framework of border spaces and intersections are used to look at tensions and accommodations in presenting sometimes conflicting versions/visions of Darwin.

The path to Project Darwin : the evolution of the AMP's organisational structure

Demutualisation became a global trend amongst financial sector firms in the last two decades of the twentieth century. Changes to the organisational foundations of mutual firms represented a shift in operational cultures and have often been viewed as an end point or demise of the co-operative business model. It is the intention of this article to investigate the extent to which this was the case within a major mutual institution, the Australian Mutual Provident, Australia's oldest and largest mutual insurer. The article's key argument is that the concept of mutuality is organic, and that within this organisation it evolved as the structure of the firm became more sophisticated as it developed from a supplier of life insurance products into a sophisticated financial services provider, which ultimately generated internal pressures to demutualise.

The Bassian Isthmus and the major ocean currents of southeast Australia influence the phylogeography and population structure of a southern Australian intertidal barnacle Catomerus polymerus (Darwin)

Southern Australia is currently divided into three marine biogeographical provinces based on faunal distributions and physical parameters. These regions indicate eastern and western distributions, with an overlap occurring in the Bass Strait in Victoria. However, studies indicate that the boundaries of these provinces vary depending on the species being examined, and in particular on the mode of development employed by that species, be they direct developers or planktonic larvae dispersers. Mitochondrial DNA sequence analysis of the surf barnacle Catomerus polymerus in southern Australia revealed an east–west phylogeographical split involving two highly divergent clades (cytochrome oxidase I 3.5 ± 0.76%, control region 6.7 ± 0.65%), with almost no geographical overlap. Spatial genetic structure was not detected within either clade, indicative of a relatively long-lived planktonic larval phase. Five microsatellite loci indicated that C. polymerus populations exhibit relatively high levels of genetic divergence, and fall into four subregions: eastern Australia, central Victoria, western Victoria and Tasmania, and South Australia. F_ST values between eastern Australia (from the eastern mitochondrial DNA clade) and the remaining three subregions ranged from 0.038 to 0.159, with other analyses indicating isolation by distance between the subregions of western mitochondrial origin. We suggest that the east–west division is indicative of allopatric divergence resulting from the emergence of the Bassian land-bridge during glacial maxima, preventing gene flow between these two lineages. Subsequently, contemporary ecological conditions, namely the East Australian, Leeuwin, and Zeehan currents and the geographical disjunctions at the Coorong and Ninety Mile Beach are most likely responsible for the four subregions indicated by the microsatellite data.

Racialised bodies encounter the city: 'long grassers' and asylum seekers in Darwin

The visibility of bodies of colour in public space can engender responses of anxiety, insecurity and discomfort in cities with white majority cultures. Such embodied responses that privilege the invisibility of whiteness have effects if they mark Aboriginal people and asylum seekers who arrive by boat as ‘out of place’ in public spaces of Australian cities. Drawing on fieldwork conducted in Darwin, I argue, however, that such white spaces are interrupted by habits of touch, multi-sensory events that contribute to fleshy moments of belonging for these racialised bodies that experience dispossession and displacement. Such belonging emerges from the intertwining fleshiness of bodies in a world where we affect and are affected by other bodies and things.

The paper explores two events held in public spaces of suburban Darwin, a weekly painting activity at a beach reserve that engages ‘Long Grassers’, Aboriginal people who live in open spaces, and a cooking session at a community centre that welcomes asylum-seeker families from a detention centre. Felix Ravaisson's philosophy of habit as virtue and spontaneous practice is a starting point for thinking about how haptic knowledges can provide a nuanced understanding of belonging, encounter and ethical engagement in a racially diverse white settler city.

Darwin after dark: illuminating suburban atmospheres

In Australian cities, culturally diverse suburban landscapes are often sensed as discomforting sites of fear and anxiety, particularly after dark. Imagined risks of encounters with bodies of colour easily policed during the day when vision is clear, but who escape biopolitical regimes of securitisation and surveillance at night contribute to such atmospheric qualities of place. These affective atmospheres of fear and anxiety that haunt bodies and limit their ability to inhabit public space, however, can provide a sense of freedom for bodies who claim suburban spaces of darkness through tactile and sonic senses. This paper draws on the contemporary literature on affective atmospheres to show how racialised Indigenous and asylum seeker bodies become present in different ways in suburban places in Darwin after dark. The paper focuses on two events – spontaneous dancing to Indigenous music at Mindil beach market and a Vigil commemorating asylum seeker lives in a suburban courtyard. Drawing on ethnographic research I explore these affective intervention that illuminate dark suburban atmospheres in Darwin. Such interventions that draw attention to the attunement of bodies to difference unsettle biopolitical regimes that victimise and patronise visible non-white bodies and contribute to rethinking racism and darkness in suburban Darwin and the Top End.

Affective energies : Sensory bodies on the beach in Darwin, Australia

Emerging debates on anti-racism within white majority cultures centre emotion and affect to explore the visceral nature of racialised encounters that unfold in public spaces of the city. This paper builds on such understandings by conceptualising whiteness as a force that exerts affective pressures on bodies of colour who are hypervisible in public spaces. I show that these pressures have the potential to wound, numb and immobilise bodies affecting what they can do or what they can become. This paper argues, however, that affective energies from human and non-human sources are productive forces that are also sensed in public spaces such as the suburban beach. These energies entangle sensuous bodies with the richness of a more-than-human world and have the potential to offer new insights into exploring how racially differentiated bodies live with difference. The paper draws on ethnographic research conducted in Darwin, a tropical north Australian city at the centre of politicised public debates on asylum seeker policy, migrant integration and Indigenous wellbeing. My attention to affective pressures and affective energies contributes to understanding how bodies with complex histories and geographies of racialisation can inhabit a world of becoming. © 2014 Elsevier Ltd.

Everyday multiculturalism: Catching the bus in Darwin, Australia

Following acts of violence in major cities, the future of multiculturalism as a philosophy and a state-sponsored policy to promote peace and interdependence in white majority societies seem uncertain. Ethnographic research that explores the lived experience of multiculturalism in shared public spaces, however, offers the possibility to explore emotional stress as well as possibilities for change in culturally diverse cities. Within this literature, however, there is little grounded research that explores Indigenous-ethnic minority relationships. This paper foregrounds and describes a seemingly mundane event such as catching a bus that entangles my body with an Aboriginal woman and a migrant woman from Fiji in Darwin, Australia. The paper demonstrates how injury, anger, shame and discomfort unfolds when bodies of colour are sites of stress. I explore the emergence of this bodily stress that has outcomes for the capacity of racially differentiated bodies of colour to respond ethically in encounters with strangers. I argue that thick descriptions of events, conceptualisations of agency as distributed and broader understandings of the social have the potential to contribute to anti-racist agendas in Euro-colonial societies with separate Indigenous and multicultural policy frameworks in ways that do not require bodies to 'accumulate' or 'inhabit' whiteness. © 2014 © 2014 Taylor & Francis.

Gestures of judgement and welcome in public spaces: hypervisible migrant newcomers in Darwin, Australia

This paper draws on ethnographic research to show how pigmentation intensities of skin and facial characteristics make bodies of colour recognisable in public spaces of Darwin, a small multiethnic and multiracial north Australian city. This paper shows that the visibility of newcomers, in particular, humanitarian migrants from countries in Africa, the Middle East and Asia, circulates negative sentiments of fear, anxiety and discomfort in public spaces when instantaneous judgements are made. These judgements of misrecognition made by residents of diverse ethnic and racial backgrounds lead to simmering tensions that unfold as visceral events of vulnerability in public spaces such as bus interchanges, neighbourhood streets, shopping centres and car parks. These events that have the potential to wound and numb bodies contribute to the “urban unconscious” of Darwin as a city where public spaces are safe with heightened surveillance. This paper argues, however, that events of hypervisibility, judgement and interracial tensions can unfold quite differently in public spaces if humanitarian migrants sense gestures of welcome, particularly from Aboriginals. Such fleeting moments of welcome in Darwin have the potential to bring together bodies with different histories and geographies of racialisation, so that multiple publics emerge through everyday habits of living with difference.

Exploring cultures of belonging in Darwin, Australia

This paper argues that the use of visual methods such as participatory video is crucial to co-producing sensory and embodied knowledges of belonging in Australian cities. These knowledges of belonging that focus on affectivity and passion have the potential to expand the worlds that racialised bodies of colour inhabit, but contemporary urban research shows an overwhelming focus on ‘talk’. This paper therefore takes the risk by engaging in a research process that is experimental, flexible and adaptive to explore diverse sensory cultures of belonging through a focus on Darwin, a small north Australian city. This is a city with a polyethnic history where Indigenous-migrant-settler race relations are recognised as more complex in comparison to large south Australian cities. The paper draws on participatory videos of two eventsin suburban Darwin - a Vigil on the side of the road opposite Airport
Lodge, an asylum seeker detention centre, and an afternoon walk along Casuarina beach where Aboriginals who live ‘rough’ camp. Using short video clips, long-term residents, migrant newcomers and asylum seekers (on bridging visas) compose an expressive narrative of the road and beach in Darwin, as places where refrains of welcome expand worlds that racialised bodies of colour inhabit. Using digital technologies the flow and juxtaposition of video clips of these events provides the possibility to craft sensory and embodied knowledges of belonging in a north
Australian city with a history of assimilationist and racially discriminatory policies.
