The use of natural light is very beneficial in office buildings because energy consumption can be reduced, and working conditions can be enhanced, which positively affect workers' health and productivity. However, bringing natural light into deep plan office buildings is not possible with simple windows or skylights, and light transport systems are necessary to bring natural light into the deep cores of buildings. Light transport systems usually need sun-tracking devices to collect natural light that are complicated, expensive and require continual maintenance. Mirrored light pipes coupled with laser cut panels (LCP) are a passive and simpler daylight transport solution and are the focus of this PhD research. The primary aim has been to improve the technology and achieve the most efficient passive solution possible through the interactive use of theoretical modelling, experimental measurements and case studies. Applications of this technology were investigated in two case studies: 1) as horizontal light pipes for daylight illumination of a high rise building proposal in the tropics; and 2) as vertical light pipes for daylight illumination of a middle-rise deep plan building proposal in a subtropical environment. In both cases, quantitative system performance under best (clear sunny sky) and worst (overcast) case scenarios was undertaken via scale model testing and mathematical modelling. The major conclusion for both case studies was that mirrored light pipe technologies, when coupled with LCP, were effective in introducing sufficient ambient light levels inside buildings and over distances > 20 m from the façade or roof. Average lux levels achieved in the space were 150 to 350 lux for the horizontal light pipes and 50 to 300 lux for vertical light pipes. However, as a passive solution, this technology has two major limitations: 1) the dependence on sun azimuth and elevation angles, which result in variations in illuminance levels during the day and the year; and potentially 2) pipe size, as pipes with a large diameter (e.g. 2 m in diameter for 20 m long pipes) are required for optimal performance, such that the large pipes may limit integration in building design. Two other solutions were assessed to circumvent these limitations to the mirrored light pipe technology: 1) a passive collector that concentrate natural light by using a fluorescent panel to reduce the size of the pipe, and 2) an active collector comprising a LCP rotating 360 degrees in a 24 hour cycle to reduce system dependence on sun azimuth and elevation angles. The low light-to-light efficiency of the fluorescent panels made them inappropriate for collecting sufficient amounts of daylight necessary for daylighting of large buildings. In contrast, the rotating LCP is a very simple active system that by rotating constantly at 15 degrees per hour, reduces the deviation angle between the panel orientation and sun azimuth angle, and significantly increased the system performance. The performance was generally better (e.g. 2.5 times better for light collection under low sun elevation angles) than the passive light pipe system with fixed LCP. However, active systems raise other issues in terms of cost-benefit in constructing, operating and maintaining such systems. Passive mirrored light pipes coupled with LCPs or simple active systems with rotating LCPs have great potential as daylight solutions for deep plan buildings as they can contribute to lowering overall energy consumption, improve workplace health and become an architectural design element. Research is still required on the implementation of the technology into buildings, but the growing trend towards 'green buildings', sustainable design and government regulations or building codes will require more daylighting use in buildings, and will motivate designers to increasingly consider and incorporate such daylighting strategies into future building designs.

This research seeks to find a design solution for reducing the energy usage in high-rise office buildings in Singapore. There are numerous methods and techniques that could be employed to achieve the purpose of designing energy efficient buildings. The Thesis explores the viability of double-skin fa??ades (DSF) to provide natural ventilation as an energy efficient solution for office buildings in hot and humid environment by using computational fluid dynamic (CFD) simulations and case study methodologies. CFD simulations were used to examine various types of DSF used in office buildings and the behaviour of airflow and thermal transfer through the DSF; the internal thermal comfort levels of each office spaces were analyzed and compared; and an optimization methodology was developed to explore the best DSF configuration to be used in high-rise office buildings in the tropics. The correlation between the fa??ade configurations, the thermal comfort parameters, and the internal office space energy consumption through the DSF is studied and presented. The research outcome of the Thesis has found that significant energy saving is possible if natural ventilation strategies could be exploited with the use of DSF. A prototype DSF configuration which will be best suited for the tropical environment in terms of its energy efficiency through cross ventilation strategy is proposed in this Thesis. A series of comprehensive and user-friendly nomograms for design optimization in selecting the most appropriate double-skin fa??ade configurations with considerations of various orientations for the use in high-rise office buildings in the tropics were also presented.

This thesis is concerned with the impact of neo-liberal reforms, initiated in response to the exigencies of a new technologically-driven global economy, on a conservative interventionist state. It is a sociological work, which encompasses history, politics, economics, organisations, social action and societal change. Between 1984 and 1990, the Fourth Labour Government embarked upon the reform of the structure and operation of the New Zealand economy. That reform ranks amongst the most radical and far-reaching in twentieth century New Zealand. Not only were the scope and magnitude of the changes significant but they were also implemented with a rapidity that took most of the country by surprise. Consequently, New Zealanders were exposed to a new and flexible economy, where market forces provided a major contrast with the ideals of equity and consensus that had shaped social conditions since the 1950s. This new environment had significant implications for the career expectations and working environment of many people, and for the delivery and content of public services. This thesis adds to the existing body of knowledge on the New Zealand reforms by capturing and investigating the perspectives of key actors who were involved, in a number of ways, with the transformation of the economy. It explores the theoretical and empirical basis of the reform programme, the restructuring process, the nature and scale of an intense commercialisation strategy, the attitudes of a new generation of workers and the reactions of New Zealanders when their ontological security came under threat. Key aspects of the reforms are framed and analysed through the transformation of the New Zealand Post Office from an icon of the interventionist state, a major employer and key service provider - to a commercial enterprise which sought to be a competitive, flexible, profit-driven organisation typical of the new economy. The experiences of politicians and senior managers who were responsible for this transformation through to individuals who depended on the organisation for services and jobs, are represented in the thesis as indicative of the actions and responses of New Zealanders, generally, regarding much broader social and organisational changes brought about by the reforms.

AIMS:The project examines the perceptions of significant stakeholders in the Catholic Education system concerning the nature, outcomes and effectiveness of the implementation of the Quality Assurance Processes developed by the Catholic Education Office (CEO), in the Archdiocese of Sydney. The study identifies factors that were assisting or hindering the effective implementation of these processes as they existed in 1996. It offers suggestions and recommendations for a future and more effective implementation of these processes. SCOPE This research is qualitative in nature, and uses interview as the main source of data collection. The Catholic schools selected for this study are those that have been involved in the implementation of the first Cycle of the Quality Assurance Processes of the CEO, Sydney. Care was taken to select two schools from each of the three Regions under which the Catholic schools in the Archdiocese of Sydney are presently organised. CONCLUSIONS The achievement and maintenance of quality outcomes has always been an integral part of Catholic Education. Through the brief historical background, this study has revealed that leaders in Catholic Education in Sydney have always sought to achieve and maintain quality outcomes since the establishment of the first schools, up until the implementation of the current quality assurance processes. This study found that the current form of Quality Assurance Processes is a most effective means of achieving and maintaining quality outcomes in the present-day Catholic education system. The Processes are professionally articulated in context with current practices, and have the potential to enhance accountability, credibility and development of both the personnel and the schools system. The implementation of the Quality Assurance Processes, to a great degree, has been effective and successful, the present study has shown that, stakeholders are becoming more and more aware of the actual nature and outcomes of these processes. The study also found great optimism among in the key player about the future of the Processes and has concluded that they well received and appreciated across the system. There were a few concerns about the clarity of aims and objectivity, the link between the different processes, and the apparently high and technical terms involved in naming/describing these Processes. The study has, therefore, concluded further that the Processes need streamlining, regular reviews and training programs to strengthen the practice and consolidate the gains and achievement. The implementation of Cycle 2 with appropriate modification is desirable.
