Energy efficiency rating systems for housing : an Australian perspective

Purpose – The purpose of this paper is to examine current trends in energy efficiency ratings and consider their likely impact on the Australian housing market.

Design/methodology/approach – The research is yet to be conducted; however a mixed method is proposed which is grounded on the theoretical model of consumer behaviour within housing markets. This model has been tested and demonstrated to be useful in predicting buyer behaviour.

Findings – Established theories of buyer perception indicate the introduction of energy efficiency rating systems will have an effect on the level of house prices.

Research limitations/implications – This research is focussed on housing in Australia but also has implications for other global housing markets which are addressing sustainability.

Practical implications – Outputs of this research have implications for policy makers, real estate agents and valuers.

Social implications – Increasing energy costs is likely to restructure the way housing markets operate with regard to sustainability and energy efficiency rating systems and also how they are understood.

Originality/value – This research will be in the Australian context utilising international modeling. As mandatory energy efficiency ratings have not been introduced, this research will be original.

Factors impeding the offsite production of housing construction in China: an investigation of current practice

The promotion of offsite production is a possible future strategic direction for the construction industry as it provides economic, environmental and social benefits. However, in China, the uptake of offsite production, particularly in the housing sector, is relatively low and few studies have identified and examined the reasons behind this trend. This research gap is addressed and factors that inhibit the wider use of offsite production in China’s housing construction industry are investigated. A questionnaire survey was carried out, examining the views of 110 construction professionals in China including developers, designers, contractors, manufacturers and suppliers. Factor analysis of 21 separate variables was undertaken which extracted six principal factors, namely: ‘constructability implementation’, ‘social climate and attitudes’, ‘architectural performance’, ‘costing’, ‘supply chain’ and ‘preparatory stage’. The findings identify both barriers and challenges to increasing the uptake of offsite production in China. This provides a rare insight about the housing construction industry in China with possible implications for other developing countries that are seeking to identify and overcome barriers to the wider uptake of offsite production.

Evaluation of housing developments for sustainability using a multi-criteria approach

New housing developments in Australia, particularly on Greenfield sites on the edge of existing urban centres, need to be sustainable in environmental and social terms if long term problems are to be avoided. Sustainability is multi-dimensional and existing analyses have been found to be inadequate in assessing housing developments holistically. This paper describes research which has used five criteria (energy use, resource use, neighbourhood character, neighbourhood connectivity and diversity), representing 31 indicators, to assess three housing precincts of a regional city in southern Australia. The method has been found to produce useful assessments of sustainability. The method has the potential to inform future housing developments and to be used to improve existing suburbs.

Effect of housing and husbandry practices on adrenocortical activity in captive Canada lynx (Lynx canadensis)

In recent years, there has been an increasing focus on the study and assessment of animal welfare in captive settings, such as zoological gardens and aquaria. Canada lynx (Lynx canadensis) are a relatively common species in zoos, yet are known to exhibit frequent reproductive problems in captive environments. We provide an exploratory analysis of housing and husbandry factors that are associated with patterns of adrenocortical activity in lynx. Adrenocortical activity was assessed using the non-invasive technique of monitoring faecal glucocorticoid metabolites (FGM). First, we calculated baseline FGM values for each individual and controlled for sex, age class, and reproductive status. The residual values were used to determine how levels of adrenocortical activity correlated with institutional husbandry practices. Second, we compared the occurrence of FGM peaks to events and disturbances recorded by keepers. Our results highlighted that adrenocortical activity is strongly correlated with: (i) the size of the enclosure, (ii) the number of hiding locations available, and (iii) the social environment. Based on our findings, we recommend that lynx should generally be housed alone (unless with dependant offspring or temporarily paired up for mating purposes), in larger enclosures and with the provision of several species-appropriate hiding locations.

From fibro shacks to McMansions: considering the impact of housing change on the sense of place in the historic Victorian coastal towns of Sorrento and Queenscliff

Eighty per cent of Australians now live within 50 kilometres of the coast.1 While most of the population remains concentrated in the large capital cities, some people have chosen small coastal towns as their permanent and or second-home destination. Greater mobility and income has increased the feasibility and attractiveness of living in these once overlooked and forgotten towns. The arrival of these new residents has changed the towns in both positive and negative ways. Declining traditional industries have been replaced by tourism and service sectors, providing a much-needed economic revival. The expectations of new residents, both permanent and non-permanent, however, have also brought challenges to the towns. Metropolitan value systems sometimes impact negatively on the unique sense of place and neighbourhood character of these towns. This paper presents both quantitative and qualitative evidence of the impact on character and sense of place in two historic coastal towns, Queenscliff and Sorrento, in southern Victoria. Census data shows how employment and the number of permanent residents have changed radically over the last 50-60 years, altering the social fabric of the towns. An analysis of the building footprint over a similar timeframe shows a growth in building size as larger houses become more common, and a growth in planning appeals for the towns is indicative of a clash of expectations between the council, long-time and new residents. While these indicators demonstrate the impact on the character of the towns as defined by their built environment, some oral accounts of local residents are used to show the emotional impact of these changes on the traditional sense of place associated with these towns. Some specific examples of changes to the built environment are provided to demonstrate that local planning schemes are not always successful in protecting neighbourhood character and that further measures are required in order to safeguard the uniqueness of coastal towns from the negative aspects of development.

Neoliberalism, economic restructuring and policy change : precarious housing and precarious employment in Australia

Housing, employment and economic conditions in many nations have changed greatly over the past decades. This paper explores the ways in which changing housing markets, economic conditions and government policies have affected vulnerable individuals and households, using Australia as a case study. The paper finds a substantial number and proportion of low income Australians have been affected by housing and employment that is insecure with profound implications for vulnerability. Importantly, the paper suggests that in Australia the economic gains achieved as a consequence of mining-related growth in the early 2000s were translated as greater employment security for some on low incomes, but not all. Enhanced access to employment in this period was differentiated by gender, with women largely missing out on the growth in jobs. For the population as a whole, employment gains were offset by increased housing insecurity as accommodation costs rose. The paper finds low income lone parents were especially vulnerable because they were unable to benefit from a buoyant labour market over the decade 2000–2010. They were also adversely affected by national policy changes intended to encourage engagement with paid work. The outcomes identified for Australia are likely to have been mirrored in other nations, especially those that have embraced, or been forced to adopt, more restrictive welfare and income support regimes.

Housing strategies that improve indigenous health outcomes

Housing is a key social determinant of health. The relationship between housing outcomes and health outcomes is bi-directional: housing affects healthoutcomes, and health affects housing outcomes. There are clear links between the quality and location of housing and health outcomes. The impacts of housing on health vary between geographic and climatic locations and contexts. There is a wide range of housing interventions that positively impact Indigenous health. One way of categorisingthese is: infrastructure improvements; addressing behavioural factors; and adjustments to policy environments.

Mapping potential risk for housing damage from ground movement due to climate change

The performance of footings in residential construction is influenced by the degree of ground movement, particularly in reactive soils, which is driven by the magnitude of change in soil moisture. New patterns of climate are affecting residential foundations and causing serious and expensive damage. This paper produces a map of potential risk for housing damage from ground movement due to climate change. Using a geographic information system, it combines information on (1) soil moisture change related to climate, using TMI as the indicator, and (2) population growth. Preliminary results, having Victoria, Australia, in the last decade as the case study, suggest that effects of climate change on soil, and resulting impacts on house foundations, are not being taken into consideration in current planning strategies for urban development. Most of the urban growth priority zones in the study area are susceptible to medium and high risk for damage. Producing new and renovated buildings that are durable in the long term is essential for the economy, environment and social welfare. The map presented here can assist policies and strategies towards urban resilience in the context of climate change.

How social work can contribute in the shift to personalised, recovery-oriented psycho-social disability support services

This paper presents the findings from an Australian study in which forty-one people, who self-identified as having a psycho-social disability as a result of mental health problems, spoke about their priorities for treatment, care and support within a personalised funding context. The research enabled an improved understanding of the choices about support that people with psycho-social disabilities would make if offered individualised funding packages. Participants prioritised specific supports to improve their health, financial situation, social connection, housing and personal relationships. A relationship with a support worker with a range of skills was identified as a key facilitator of these life goals, but people with psycho-social disabilities also valued opportunities to have discretionary funds to directly address the major problems they face, including stigma, discrimination and poverty. The paper argues that social workers can potentially fill a range of roles and are well placed to work in partnership with people with psycho-social disabilities. Particularly, they have skills in co-production of services, negotiation and advocacy that are required if individual funding is to be maximised for user control, social justice and personal recovery outcomes.

Investigating the development of traditional and modern housing design in Libyan architecture

The design of housing is one of the most difficult tasks in the field of architecture. Housing meets people’s functional, social and spiritual needs. The fundamental task of this study has been to investigate the features of traditional and contemporary housing making it possible to describe them and then use this comparison to understand the differences between them

Use of indicators to assess the sustainability of housing developments in Australia

Most new housing in Australia is occurring on greenfield sites on the edges of the capital cities. These housing developments are often criticised for their social and environmental unsustainability. These unsustainable suburbs are a legacy for future generations. They will create dire social and environmental problems if a serious economic downturn was to occur or a resource shortage e.g. oil was to make accessibility impossible. Coupled to these threats is that of the social ‘undesirability’ of isolated suburbs where only those on low incomes made their home. Most of those on higher incomes seek established suburbs which have ‘character’, social amenities and ease of access. Typically, these are in older suburbs close to city centres. This paper describes a methodology that has been developed to analyse past and future housing developments. The results of the analysis can provide a guide to improving the sustainability of these suburbs. The methodology uses several criteria to reflect the fact that no single criterion is adequate to describe or analyse the sustainability of a housing development. Sustainability should embrace social and environmental perspectives, so a multi-criteria analysis is appropriate. The theoretical framework for this methodology has been described elsewhere. However, in this previous work only five criteria were considered: energy use, resource use, neighbourhood character, neighbourhood connectedness and social diversity. In each case, high and low sustainability practice has been identified so that ranking is possible. This paper initially summarizes the way in which these previous five criteria are assessed but then adds a sixth criterion (social connectedness) because of a perceived gap in the previous assessment. The results of an analysis of three suburbs reported in the previous work are updated. They score poorly in terms of social connectedness underlining the need to ‘repair’ these suburbs in order to improve their overall sustainability.
