Reliability of building embodied energy modelling: an analysis of 30 Melbourne case studies

Building design decisions are commonly based on issues pertaining to construction cost, and consideration of energy performance is made only within the context of the initial project budget. Even where energy is elevated to more importance, operating energy is seen as the focus and embodied energy is nearly always ignored. For the first time, a large sample of buildings has been assembled and analysed in a single study to improve the understanding of the relationship between energy and cost performance over their full life cycle. Thirty recently completed buildings in Melbourne, Australia have been studied to explore the accuracy of initial embodied energy prediction based on capital cost at various levels of model detail. The embodied energy of projects, elemental groups, elements and selected items of work are correlated against capital cost and the strength of the relationship is computed. The relationship between initial embodied energy and capital cost generally declines as the predictive model assumes more detail, although elemental modelling may provide the best solution on balance.

The ethics of sustainable housing design : the dilemma for practising architects

Globally wc arc grappling with the concept of sustainability. What does it mean and how should we respond to ensure that the planet's current ecosystems survive? Architects are in the 'front line' because of the impact of buildings on resource use and waste generation. Most definitions of sustainability are unhelpful because of their wordiness, lack of detail or ambiguity. Others distort the concept of sustainability to allow business-as-usual (i.e., unsustainable) activity to continue. Using one particular model of sustainability, this paper explores the ethical dilemma faced by architects in the residential sector when confronted by a client who wants a house that is clearly unsustainable. The paper begins with definitions of sustainability and ethics; then the literature examining sustainable architecture is reviewed for possible solutions to the dilemma. Two indicators are suggested to make a broad-brush assessment of sustainability. Finally, some practical options for the practising architect are suggested.

Combined evaluation of workplace performance using occupants' subjective assessment and objective measurement of environmental conditions : a case study

The case study presents findings from a program of pre- and post-evaluations of buildings sponsored by the NSW government. The program aims to demonstrate leadership in the delivery of government accommodation and to provide feedback into the building design and management process.

The results from a combined evaluation of an ABGR 4.5 star government building using the KODO probe© occupant surveys and measures of environmental conditions, carried out by the Mobile Architecture and Built Environment Laboratory (MABEL) at Deakin University are summarised. In particular the paper will present the benefits of innovative performance evaluation of property for commercial benefit using the KODO productivity topographic maps©.

These maps isolate where facility solutions are needed as opposed to tenant/occupant solutions in order to optimise building and business outcomes with minimal capital investment.

Reducing the risk of re-offending among Australian indigenous offenders : what works for whom?

This paper discusses the application of the “what works” approach to the rehabilitation of indigenous Australian offenders. It is suggested that those from indigenous cultures may not share some of the theoretical assumptions that underpin the “what works” approach, potentially leading to discussion about the cultural appropriateness of rehabilitation programs. Finally, some options are presented about how cultural differences might be understood in ways that facilitate the further development of rehabilitation programs for indigenous peoples.

A comprehensive framework for assessing the life cycle energy of building construction assemblies

Environmental decision making during the building design process has typically focused on improvements to operational efficiencies. Improvements to thermal performance and efficiency of appliances and systems within buildings both aim to reduce resource consumption and environmental impacts associated with the operation of buildings. Significant reductions in building energy and water consumption are possible; however often the impacts occurring across the other stages of a building‘s life are not considered or are seen as insignificant in comparison.

Previous research shows that embodied impacts (raw material extraction, processing, manufacture, transportation and construction) can be as significant as those related to building operation. There is, however, limited consistent and comprehensive information available for building designers to make informed decisions in this area. Often the information that is available is from disparate sources, which makes comparison of alternative solutions unreliable and risky. lt is also important that decisions are made from a life cycle perspective, ensuring that strategies to reduce environmental impacts from one life cycle stage do not come at the expense of an increase in overall life cycle impacts

A consistent and comprehensive framework for assessing and specifying building assemblies for enhanced environmental outcomes does not currently exist. This paper presents the initial findings of a project that aims to establish a database of the life cycle energy requirements of a broad range of construction assemblies, based on a comprehensive assessment framework. Life cycle energy requirements have been calculated for eight standard residential construction assemblies integrating an innovative embodied energy assessment technique with thermal performance simulation modelling and ranked according to their performance.

Examination of the "all hazards" approach to disaster management as applied to field disaster management and pre-hospital care in Australia

Disasters, emergencies, incidents, and major incidents - they all come back to the same thing regardless of what they are called. The common denominator is that there is loss of life, injury to people and animals and damage and destruction of property. The management of such events relies on four phases: 1. Prevention 2. Preparation 3. Response 4. Recovery Each of these phases is managed in a different way and often by different teams. Here, concentration has been given to phases 2 and 3, with particular emphasis on phase 3, Response. The words used to describe such events are often related to legislation. The terminology is detailed later. However, whatever the description, whenever prevention is not possible, or fails, then the need is to respond. Response is always better when the responders are prepared. Training is a major part of response preparation and this book is designed to assist those in the health industry who need to be ready when something happens. One of the training packages for responders is the Major Incident Medical Management and Support (MIMMS) Course and this work was designed to supplement the manual prepared by Hodgetts and Macway-Jones(87) in the UK. Included is what the health services responder, who may be sent to an event in which the main concern is trauma, should know. Concentration is on the initial response and does not deal in any detail with hospital reaction, the public health aspects, or the mental health support that provides psychological help to victims and responders, and which are also essential parts of disaster management. People, in times of disaster, have always been quick to offer assistance. It is now well recognised however, that the 'enthusiastic amateur', whilst being a well meaning volunteer, isn't always what is needed. All too often such people have made things worse and have sometimes ended up as victims themselves. There is a place now for volunteers and there probably always will be. The big difference is that these people must be well informed, well trained and well practiced if they are to be effective. Fortunately such people and organisations do exist. Without the work of the St John Ambulance, the State Emergency Service, the Rural Fire Service the Red Cross and the Volunteer Rescue Association, to mention only a few, our response to disasters would be far less effective. There is a strong history of individuals being available to help the community in times of crisis. Mostly these people were volunteers but there has also always been the need for a core of professional support. In the recent past, professional support mechanisms have been developed from lessons learned, particularly to situations that need a rapid and well organised response. As lessons are learned from an analysis of events, philosophy and methods have changed. Our present system is not perfect and perhaps never will be. The need for an 'all-hazards approach' makes detailed planning very difficult and so there will probably always be criticisms about the way an event was handled. Hindsight is a wonderful thing, provided we learn from it. That means that this text is certainly not the 'last word' and revisions as we learn from experience will be inevitable. Because the author works primarily in New South Wales, many of the explanations and examples are specific to that state. In Australia disaster response is a State, rather than a Commonwealth, responsibility and consequently, and inevitably, there are differences in management between the states and territories within Australia. With the influence of Emergency Management Australia, these differences are being reduced. This means that across state and territory boundaries, assistance is common and interstate teams can be deployed and assimilated into the response rapidly, safely, effectively and with minimum explanation. This text sets out to increase the understanding of what is required, what is in place and how the processes of response are managed. By way of introduction and background, examples are given of those situations that have occurred, or could happen. Man Made Disasters has been divided into two distinct sections. Those which are related to structures or transport and those related directly to people. The first section, Chapter 3, includes: • Transport accidents involving land, rail, sea or air vehicles. • Collapse of buildings for reasons other than earthquakes or storms. • Industrial accidents, including the release of hazardous substances and nuclear events. A second section dealing with the consequences of the direct actions of people is separated as Chapter 4, entitled 'People Disasters'. Included are: • Crowd incidents involving sports and entertainment venues. • Terrorism From Chapter 4 on, the emphasis is on the Response phase and deals with organisation and response techniques in detail. Finally there is a section on terminology and abbreviations. An appendix details a typical disaster pack content. War, the greatest of all man made disasters is not considered in this text.

Acid drainage, limnology and bioremediation of western Victorian coal mine lakes

Rehabilitation of Alcoa's Anglesea open cut brown coal mine to a healthy lake has many environmental challenges. The study of regional acid drainage, limnology of Wenslydale Coal Mine Lake and passive bioremediation of acid mine water has shown that a healthy lake can be created.

Factors impacting story-grammar production in children's narrative accounts of events

This thesis examined factors associated with increased story-grammar production in police interviews with children who allege abuse. These factors included the child's age, the type of question asked and the nature of the event experienced by the child. Recommendation for improving story-grammar, which in turn enhances witness credibility, were discussed. The portfolio explored how an awareness of specific responsivity factors can inform treatment recommendations and execution in rehabilitation of offenders with substance use issues. Four case studies are presented in illustration.

Therapeutic Jurisprudence, juvenile justice and the UN Convention on the Rights of the Child : do they coexist?

The UN Convention on the Rights of the Child provides children and young people with over 40 substantive rights, the five outcomes of which are living a healthy lifestyle, staying safe, enjoying and achieving, making a positive contribution, and economic wellbeing. Moreover, Article 3 dictates that all organizations concerned with children should work towards what is best of each child. It is not clear how these rights translate to the care of children and young people who come before the courts (particularly those who are subsequently incarcerated). A review of the literature suggests that while best practice guidelines for the treatment and rehabilitation of adult offenders has moved forward, there is little consensus about how this might be achieved for young people. Therapeutic Jurisprudence (TJ) needs to extend beyond its current considerations of the rights of children and young people, and to expand its focus to the extent to which international human rights standards are complied with in the cases of juveniles in the criminal justice system. This presentation will (a) explore the extent to which current practices in juvenile justice are consistent with the UN's Convention and (b) whether the adoption a rehabilitative and treatment approach based on a TJ framework might serve to improve outcomes for young people and ensure their rights are not being violated.

A review of occupant control on natural ventilation

According to IPCC (Intergovernmental Panel on Climate Change), the largest use of energy in commercial buildings is space heating in colder climates and air conditioning in hot climates. In Europe, the Directive on the energy performance of buildings EPBD (European Energy Performance of Buildings Directive) [1] provides a framework for national building performance regulations and calculation procedures. However, there are often large discrepancies between calculated and measured energy performance of buildings. One main reason is the behaviour of occupants, which is often not reflected in calculation models.

Better definitions, better buildings?

Because of the magnitude of their impact on the environment, the way we design, build and operate our buildings must change. So-called ‘sustainable’ buildings are now appearing in our cities. However, the term ‘sustainable’ is now so widely used that it has lost all meaning. Other equally ill-defined descriptions are also being used of the new generation of buildings appearing in the built environment. These terms, including ‘environmentally friendly’, ‘low energy’ and ‘green’. This paper argues that a lack of clarity over meaning can foster illusions, reflect careless thinking and/or provide cover for a business-as-usual agenda. In universities, courses for today’s architecture and construction management students are being redesigned to include ‘sustainability’. However, a review of subject guides from Schools of Architecture in Australian universities indicates that ‘sustainability’ is also being used misleadingly. While there is merit in both of the professional accreditation systems for buildings in Australia, there is certainly room for improvement. One scheme reinforces illusions by rewarding features that should merely be regarded as good building design. The ‘sustainability’ objectives of the other scheme have narrowed significantly from the original intent. The authors conclude that the critical thinking of our students will be sharpened by defining sustainability correctly and that meaningless descriptors of buildings must be challenged.

Narrative identity and offender rehabilitation

The rehabilitation of offenders is an evaluative and capability-building process and is concerned with promoting primary goods and managing risk. At the heart of this process is the construction of a more adaptive narrative identity and the acquisition of capabilities to enable offenders to secure important values in their postrelease environments. In this article, the authors examine the idea of narrative identity and its relationship to values and to assessment and treatment.

Wood to water : short-term effects of the re-introduction of wood to streams in agricultural environments

Rehabilitation of streams on agricultural properties has become a priority for landholders and managers in recent years in Australia. Fencing and re-vegetation of riparian zones are first priorities to improve riparian habitat values and biodiversity, however changes to in-stream habitat complexity are unlikely to result in the short term. Little evidence exists to guide subsequent rehabilitation actions to address this issue. Artificially re-introducing wood to such streams may be a useful strategy to increase habitat complexity more rapidly, thereby improving in-stream biodiversity values. To test this hypothesis, as a part of the larger Productive Grazing, Healthy Rivers project, small pieces of wood were introduced to eight sites on beef and dairy properties across southern Victoria, monitoring aquatic macroinvertebrates, water quality, hydrology and habitat quality. Comparing macroinvertebrate communities before and after treatment, and between experimental and control sites, changes in community composition and colonisation are explored.

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.

Questions of (re)production and legitimation : a second screening of 3 films on teacher-student relations

This study considers three Hollywood films that take, as their subject, a teacher-hero confronted with a 'problem' group of students and, as their narrative, the rehabilitation of these students and the resolution of their problems. Employing a Bourdieuian analysis, we attempt a second screening of these films on two levels: first, by stepping inside these celluloid classrooms, so to speak, and narrating a different text, one that is spoken from the position of students and which challenges each film's portrayal of good people achieving fine things; and secondly, by screening for gaps in their accounts of schooling, exposing their limited frames of reference and their legitimacy to speak on behalf of authentic classrooms. The first of these projects is undertaken as a way of challenging teachers and interested others to be wary of uncritical readings of popular images of teaching, whereas the second provides a beginning from which to consider how teachers' pedagogy and school curricula can be informed by a radical democratic view of education - how teachers might embrace the foreign.
