Developing sustainable housing through building utilities and transport innovation

Sustainability concerns every citizen. Housing affordability and sustainable solutions are being highlighted in research and practice in many parts of the world. This paper discusses the development of a Commuter Energy and Building Utilities System (CEBUS) in sustainable housing projects as a means of bridging the gap between current median house pricing and target affordable house pricing for low income earners. Similar scales of sustainable housing development cannot be achieved through independent application of current best practice methods in ecologically sustainable development strategies or transit oriented development master plans. This paper presents the initial stage of research on first capital and ongoing utilities and transport cost savings available from these sustainable design methods. It also outlines further research and development of a CEBUS Dynamic Simulation Model and Conceptual Framework for the Australian property development and construction industry.

Periodically forced natural convection through the roof of an attic-shaped building

In this study, numerical simulations of natural convection in an attic space subject to diurnal temperature condition on the sloping wall have been carried out. An explanation of choosing the period of periodic thermal effect has been given with help of the scaling analysis which is available in the literature. Moreover, the effects of the aspect ratio and Rayleigh number on the fluid flow and heat transfer have been discussed in details as well as the formation of a pitchfork bifurcation of the flow at the symmetric line of the enclosure.

Nobody says no : student self-censorship in a collaborative knowledge building activity

This paper explores student self-censorship within an online learning environment. Self-censorship in group activity can be seen as a two-edged sword. While it can be advantageous that a student censor personal frustration and angst when working with others, if the self-censorship impacts on the cognitive contribution a student makes then this may significantly impact upon the overall quality of the group’s collective knowledge artefact. This paper reports on a study where it was found that students had self censored both their feelings and ideas as they collaboratively worked together.

Planning for SMEs’ Proactive Waste Management in Office Building Retrofit Projects

Office building retrofit projects face many challenges for on-site waste management. While the projects themselves have the potential for a significant level of reuse and recycling from decon-struction and demolition, their unique characteristics often prohibit direct application of existing waste management systems, which are typically based on managing waste generated through new material application in new build projects. Moreover, current waste management plans include no stimuli to involve Small and Medium Enterprises (SMEs) for on-site waste management. As SMEs carry out the majority of on-site work as subcontractors, their active involvements will result in more proactive approaches to waste management and enhance project delivery. This paper discusses the interim results of a continuing research aimed at engaging SMEs in the planning processes of waste management through the collaboration between subcontractors and main contractors of retrofitting projects. It introduces a conceptual model for SMEs to proactively plan and manage on-site waste generation for both deconstruction and construction stages, before traditional waste management plans by the main contractor come into place. The model also suggests a collaboration process between SMEs as subcontractors and large companies as the main contractor to improve the involvement and performance of SMEs in waste management of office building retrofit projects.

Building a USDL repository as a service using MDE

The decision to represent the USDL abstract syntax as a metamodel, shown as a set of UML diagrams, has two main benefits: the ability to show a well- understood standard graphical representation of the concepts and their relation- ships to one another, and the ability to use object-oriented frameworks such as Eclipse Modeling Framework (EMF) to assist in the automated generation of tool support for USDL service descriptions.

Assessment of requirements for establishment of a framework to enhance implementation of quality practices in building projects

Quality, in construction projects should be regarded as the fulfillment of expectation of those contributors involved in such projects. Although a significant amount of quality practices have been introduced within the industry, attainment of reasonable levels of quality in construction projects continues to be an ongoing problem. To date, some research into the introduction and improvement of quality practices and stakeholder management has been undertaken, but so far no major studies have been completed that comprehensively examine how greater consideration of stakeholders’ perspectives of quality can be used to contribute to final project quality outcomes. This paper aims to examine the requirements for development of a framework leading to more effective involvement of stakeholders in quality planning and practices thus ultimately contributing to higher quality outcomes for construction projects. Through an extensive literature review it highlights various perceptions of quality, categorizes quality issues with particular focus on benefits and shortcomings and also examines the viewpoints of major stakeholders on project quality. It proposes a set of criteria to be used as a basis for a quality practice improvement framework, which will provide project managers and owners with the required information and strategic direction to achieve their own and their stakeholders’ targets for implementation of quality practices leading to the achievement of improved quality outcomes on future projects.

Building engaged, sustainable online communities : a case study of an adventure travel website

This paper will provide an overview of a join research initiative being developed by the Queensland University of Technology in conjunction with the Australian Smart Services Cooperative Research Centre in relation to the development and analysis of online communities. The intention of this project is to initially create an exciting and innovative web space around the concept of adventure travel and then to analyse the level of user engagement to uncover possible patterns and processes that could be used in the future development of other virtual online communities. Travel websites are not a new concept and there are many successful examples currently operating and generating profit. The intention of the QUT/Smart Services CRC project is to analyse the site metrics to determine the following: what specific conditions/parameters are required to foster a growing and engaged virtual community; when does the shift occur from external moderation to a more sustainable system of self-moderation within the online community; when do users begin to take ownership of a site and take an invested interested in the content and growth of an online community; and how to retain active contributors and high-impact power users on a long-term basis. With the travel website rapidly approaching release, this paper begins the process of reflection, outlining the process undertaken and the findings so far aggregated whilst also positioning the project within the greater context of current online user participation and user generated content research.

The role of universities in building prosperous knowledge cities : the Malaysian experience

This paper explores the role and importance of universities, particularly in the Malaysian context, for building prosperous knowledge cities of the rising knowledge economy. It aims to shed light on how universities contribute to the knowledge-based development of Malaysian cities by undertaking a case study investigation. In the case of Bandar Seri Iskandar, the paper scrutinises the creation – from scratch – of a knowledge city, including the establishment of new public and private universities and hence providing a unique opportunity to understand how the idea of the knowledge economy has permeated economic development policy within a developing country context. The research findings reveal that in Malaysia, much like many of the developed countries, universities are being positioned to play a major role in supporting knowledge city (trans)formation. While there has been a tangible success on the spatial development based on a rapid land use change towards accommodating knowledge-intensive land use and activities, the research reports that a more concerted and coordinated effort from academia, public and private sectors are needed to further foster the growth and development of economical, environmental, institutional and social aspects of Bandar Seri Iskandar to become a fully functioning prosperous knowledge city.

Contributions of knowledge-based foundations of universities in knowledge city formation : a Malaysian case study

Purpose – In the 21st Century, as knowledge, technology and education are widely accepted to play key roles in the local economic development, the importance of making space and place for knowledge production is, therefore, on the rise resulting many city administrations and urban policy-makers worldwide restructuring their cities to become highly competitive and creative. Consequently, this has led to a new type of city form, knowledge city, and a new approach in their development, knowledge-based urban development. In this context, knowledge-based foundations of universities are regarded as one of the key elements for knowledge-based urban development and knowledge city formation due to their ability to provide a strong platform for knowledge generation, marketing and transfer. This paper aims to investigate the role and importance of universities and their knowledge-based foundations in the context of developing countries, particularly in Malaysia, in building prosperous knowledge cities of the era of the knowledge economy. Design/Methodology/Approach – The main methodological techniques employed in this research includes: a thorough review of the literature on the role of universities in spatial and socio-economic development of cities; a best practice analysis and policy review of urban and regional development policies targeting to use of university clusters in leveraging knowledge-based development, and; a case study in Malaysia with a review of various policy documents and strategic plans of the local universities and local and state authorities, interviews with key actors, and a trend analysis of local socio-economic and spatial changes. Originality/Value – This paper reports the findings of a pioneering research on examining the role and impact of universities and their knowledge-based foundations, in the context of Malaysia, in building knowledge cities of the era of the knowledge economy. By undertaking a case study investigation in Bandar Seri Iskandar, which is a newly emerging Malaysian knowledge city, located in Perak, Malaysia, the paper sheds light on an important issue of the 21st Century of how universities contribute to the knowledge-based development of cities. Practical Implications – Universities with their rich knowledge-based foundations are increasingly being recognised as knowledge hubs, exercising a strong influence in the intellectual vitality of the city where they are embedded. This paper reveals that universities, in joint action with business and society at large, are necessary prerequisites for constructing and maintaining knowledge societies and, therefore, building prosperous knowledge cities. In light of the literature and case findings, the paper sheds light on the contribution of knowledge-based foundations of universities in knowledge city formation and provides generic recommendations for cities and regions seeking knowledge city transformation.

Journeys with friends

Journeys with Friends Truna aka J. Turner, Giselle Rosman and Matt Ditton Panel Session description: We are no longer an industry (alone) we are a sector. Where the model once consisted of industry making games, we now see the rise of a cultural sector playing in the game space – industry, indies (for whatever that distinction implies) artists (another odd distinction), individuals and well … everyone and their mums. This evolution has an affect – on audiences and who they are, what they expect and want, and how they understand the purpose and language of these “digital game forms’; how we talk about our worlds and the kinds of issues that are raised; on what we create and how we create it and on our communities and who we are. This evolution has an affect on how these works are understood within the wider social context and how we present this understanding to the next generation of makers and players. We can see the potential of this evolution from industry to sector in the rise of the Australian indie. We can see the potential fractures created by this evolution in the new voices that ask questions about diversity and social justice. And yet, we still see a ‘solution’ type reaction to the current changing state of our sector which announces the monolithic, Fordist model as desirable (albeit in smaller form) – with the subsequent ramifications for ‘training’ and production of local talent. Experts talk about a mismatch of graduate skills and industry needs, insufficient linkages between industry and education providers and the need to explore opportunity for the now passing model in new spaces such as adver-games and serious games. Head counts of Australian industry don’t recognise trans media producers as being part of their purview or opportunity, they don’t count the rise of the cultural playful game inspired creative works as one of thier team. Such perspectives are indeed relevant to the Australian Games Industry, but what about the emerging Australian Games Sector? How do we enable a future in such a space? This emerging sector is perhaps best represented by Melbourne’s Freeplay audience: a heady mix of indie developers, players, artists, critical thinkers and industry. Such audiences are no longer content with an ‘industry’ alone; they are the community who already see themselves as an important, vibrant cultural sector. Part of the discussion presented here seeks to identify and understand the resources, primarily in the context of community and educational opportunities, available to the evolving sector now relying more on the creative processes. This creative process and community building is already visibly growing within the context of smaller development studios, often involving more multiskilling production methodologies where the definition of ‘game’ clearly evolves beyond the traditional one.

Critical constructability activities in building projects

Fundamental studies on constructability issue done in United States, United Kingdom and Australia illustrate capability of this concept to affect overall objectives of construction projects. It can result in significant cost and time savings and improved final quality by consideration of construction contractors experiences during conceptual planning and design phases. As intensive as these studies are, they do not attempt to investigate importance of these activities in order to find each of their specific barriers separately. This research explores Constructability Activities (CAs) in all project phases separately based on amount of contractors involvement in each activity and also amount of gap that exists between target and actual effects of each activity on achieving the final objectives of building projects in Malaysia. It ends to development of Critical Constructability Activities (CCAs). This research is crucial to gaining a better understanding of CCAs which are caused based on contractors higher participation percentage and larger gaps between their target and actual effects on achieving the final aims of the project. This research highlights the need to overcome barriers of CAs implementation in building projects. This study recommends construction stakeholders to concentrate more on CCAs in order to achieve the overall objectives of the project much faster and easier.

The politicization of youth crime in Scotland and the rise of the 'Burberry Court'

In 2003, the youth justice system in Scotland entered a new phase with the introduction of a pilot youth court. The processing of persistent 16 and 17 year old (and serious 15 year olds) represented a stark deviation from a ‘child centred’ and needs-oriented state apparatus for dealing with young offenders to one based on deeds and individual responsibility. This article, based on an evaluation funded by the Scottish Executive, is the first to provide a critical appraisal of this youth justice reform. It examines the views of the judiciary and young offenders and reveals that the pilot youth court in Scotland represents a punitive excursion that poses serious concerns for due process, human rights and net widening.

O'Neill Building Nudgee College

This project involved the complete refurbishment and extension of a 1980’s two-storey domestic brick building, previously used as a Boarding House (Class 3), into Middle School facilities (Class 9b) on a heritage listed site at Nudgee College secondary school, Brisbane. The building now accommodates 12 technologically advanced classrooms, computer lab and learning support rooms, tuckshop, art room, mini library/reading/stage area, dedicated work areas for science and large projects with access to water on both floors, staff facilities and an undercover play area suitable for assemblies and presentations. The project was based on a Reggio Emilia approach, in which the organisation of the physical environment is referred to as the child’s third teacher, creating opportunities for complex, varied, sustained and changing relationships between people and ideas. Classrooms open to a communal centre piazza and are integrated with the rest of the school and the school with the surrounding community. In order to achieve this linkage of the building with the overall masterplan of the site, a key strategy of the internal planning was to orientate teaching areas around a well defined active circulation space that breaks out of the building form to legibly define the new access points to the building and connect up to the pathway network of the campus. The width of the building allowed for classrooms and a generous corridor that has become ‘breakout’ teaching areas for art, IT, and small group activities. Large sliding glass walls allow teachers to maintain supervision of students across all areas and allow maximum light penetration through small domestic window openings into the deep and low-height spaces. The building was also designed with an effort to uphold cultural characteristics from the Edmund Rice Education Charter (2004). Coherent planning is accompanied by a quality fit-out, creating a vibrant and memorable environment in which to deliver the upper primary curriculum. Consistent with the Reggio Emilia approach, materials, expressive of the school’s colours, are used in a contemporary, adventurous manner to create panels of colour useful for massing and defining the ‘breakout’ teaching areas and paths of travel, and storage elements are detailed and arranged to draw attention to their aesthetic features. Modifications were difficult due to the random placement of load bearing walls, minimum ceiling heights, the general standard of finishes and new fire and energy requirements, however the reuse of this building was assessed to be up to 30% cheaper than an equivalent new building, The fit out integrates information technology and services at a level not usually found in primary school facilities. This has been achieved within the existing building fabric through thoughtful detailing and co-ordination with allied disciplines.

Sub-tropical high-density, low rise residential buildings: case study 3

The case study 3 team viewed the mitigation of noise and air pollution generated in the transport corridor that borders the study site to be a paramount driver of the urban design solution. These key urban planning strategies were adopted: * Spatial separation from transport corridor pollution source. A linear green zone and environmental buffer was proposed adjacent to the transport corridor to mitigate the environmental noise and air quality impacts of the corridor, and to offer residents opportunities for recreation * Open space forming the key structural principle for neighbourhood design. A significant open space system underpins the planning and manages surface water flows. * Urban blocks running on east-west axis. The open space rationale emphasises an east-west pattern for local streets. Street alignment allows for predominantly north-south facing terrace type buildings which both face the street and overlook the green courtyard formed by the perimeter buildings. The results of the ESD assessment of the typologies conclude that the design will achieve good outcomes through: * Lower than average construction costs compared with other similar projects * Thermal comfort; A good balance between daylight access and solar gains is achieved * The energy rating achieved for the units is 8.5 stars.

Subtropical towers typology design : RNA showground case study

The QUT Team developed an idea for a new residential housing typology that is appropriate for sites where the best views are in the opposing direction to the preferable climatic orientation. The interlocking configuration creates a double height external living space in every apartment, creating further opportunities for cross ventilation and natural daylight. Unlike conventional double loaded housing typologies, the interlocking configuration only requires a continuous public circulation corridor every second level. The cores that service this corridor are separated to either end of the tower and open areas. The configuration of the interlocking apartments creates an interesting composition of solid and void when viewed externally. This undulating facade petternation assists in articulating the large building mass. The project was evaluated by independent consultants and found to be cost effective, and at the same time delivering energy efficient high density liveability. The project was presented to a meeting of the Australian Council on Tall Buildings seminar on 15 September 2010.
