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.

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 Declining traditional industries have been replaced by tourism and service sectors, providing a much-needed economic revival.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.

TMI for urban resilience : measuring and mapping long-term climate change effects on soil moisture

The effect of climate change on the shallow expansive foundation conditions of resident dwellings is costing several hundred billion dollars worldwide. The design and costs of constructing or repairing residential footings is greatly influenced by the degree of ground movement, which is driven by the magnitude of change in soil moisture. The impacts of climate change on urban infrastructure are expected to include accelerated degradation of materials and foundations of buildings and facilities, increased ground movement, changes in ground water affecting the chemical structure of foundations, and fatigue of structures from extreme storm events. Previous research found that residential houses that were built less than five years ago have suffered major cracks and other damage caused by slab movement after record rainfall. The Thornthwaite Moisture Index (TMI) categorises climate on the basis of rainfall, temperature, potential evapotranspiration and the water holding capacity of the soil. Originally TMI was mainly used to map soil moisture conditions for agriculture but soon became a method to predict pavement and foundation changes. Few researchers have developed TMI maps for Australia, but generally, their accuracy is low or unknown, and their use is limited. The aims of this paper are: (1) To produce accurate maps of TMI for the state of Victoria for 100 years (1913 to 2012) in 20 year periods using long-term historical climatic data and advanced spatial statistics methods in GIS, and (2) Analyse the spatial and temporal changes of TMI in Victoria. Preliminary results suggest that a better understanding of climate change through long-term TMI mapping can assist urban planning and guide construction regulations towards the development of cities which are more resilient.

Validating a teaching survey which drives increased response rates in a unit survey

At Curtin University, student perceptions of teaching and learning are gathered and reported online through eVALUate, a system that includes separate unit and teaching surveys. This article reports the development and validation of one of those surveys, the eVALUate teaching survey, which was developed based on the research literature on excellent teaching and evaluation. Since its development in 2006, repeated statistical testing using progressively larger samples has shown that the survey is valid and reliable. Moreover, the way in which the teaching survey is deployed within eVALUate, appended to the unit survey, which provides crucial institutional data, has significantly increased university response rates. This validated instrument is used for self-reflection, professional development, and rewarding staff.

Graduate attributes as a focus for institution-wide curriculum renewal: innovations and challenges

Curtin University's Curriculum 2010 (C2010) initiative aimed at ensuring degree programs were excellent and sustainable. Before C2010, graduate attributes were not universally emphasised and indicators showed room for improvement in generic skills. C2010 focused on embedding graduate attributes through three strategies. The first was embedding graduate attributes in degree programs and mapping for constructive alignment of outcomes and assessments. The second strategy was related: programs were reviewed drawing on evidence including perspectives of graduates, employers and program teams on the relative importance of graduate attributes and the extent to which they were generally demonstrated or developed. The third strategy was a university-wide eportfolio system enabling students' self- and peer-assessment of graduate attributes. Since completion of C2010, proxy indicators show improvement. However, this paper highlights the challenges associated with graduate attributes and renewal. These include: academic staff engagement, the time needed for innovations to come to fruition and evidencing achievement of graduate attributes.
