ItemNo Preview AvailableWater-Energy-GHG emissions accounting for urban water supply: A case study on an urban redevelopment in Melbourne(E.W. Publications, 2013-07-01)This paper presents a conceptual accounting framework to quantify the life cycle energy use and GHG emissions of alternative urban water supply strategies. The framework enables the comparative analysis of alternative strategies to design a fit-for-purpose water supply system that takes into account water supply, energy use and GHG emissions and has been tested on the Fisherman’s Bend development site in Melbourne Metropolitan region and results are presented. This study does not include the environmental and social benefits incurred from deploying multiple water sources, which must be considered before making strategic decision about implementation of alternative sources of water supply.

ItemSustainable Prefabricated Modular Buildings(ICSB, 2014)Economy, speed of construction and improved environmental performance are critical variables that challenge the modern construction industry to strike a balance between. Employing innovative prefabricated modular structures is one key strategy used to achieve these goals. Therefore, there is an increasing demand for detailed scientific research that deals with the potential environmental benefits of prefabrication, particularly in areas of embodied energy savings resulting from waste reduction and improved efficiency of material usage. This paper gives a brief overview of prefabricated modular structures and aims to highlight the sustainability characteristics of this technology compared to conventional construction methods. A case study was carried out on an eight-storey, residential building. It was found that a steel-structured prefabricated system resulted in a significantly reduced material consumption of up to 78% by mass compared to conventional concrete construction. However, the prefabricated steel building resulted in an increase in embodied energy compared to the concrete building mainly due to the inherent characteristics of steel manufacturing processes. This form of construction has the potential to contribute significantly towards improved environmental sustainability in the construction industry while providing fast outputs with value for the investments.

ItemTime-efficient post-disaster housing reconstruction with prefabricated modular structures(Open House International Association, 2014-09-01)With many natural disasters such as earthquakes, cyclones, bushfires and tsunamis destroying human habitats around the world, post-disaster housing reconstruction has become a critical topic. The current practice of post-disaster recon- struction consists of various approaches that carry affected homeowners from temporary shelters to permanent hous- ing. While temporary shelters may be provided within a matter of days as immediate disaster relief, permanent hous- ing can take years to complete. However, time is critical, as affected communities will need to restore their livelihoods as soon as possible. Prefabricated modular construction has the potential to drastically improve the time taken to pro- vide permanent housing. Due to this time-efficiency, which is an inherent characteristic of modular construction, it can be a desirable strategy for post-disaster housing reconstruction. This paper discusses how prefabricated modular struc- tures can provide a more time-efficient solution by analysing several present-day examples taken from published post- disaster housing reconstruction processes that have been carried out in different parts of the world. It also evaluates how other features of modular construction, such as ease of decommissioning and reusability, can add value to post- disaster reconstruction processes and organisations that contribute to the planning, design and construction stages of the reconstruction process. The suitability of modular construction will also be discussed in the context of the guidelines and best practice guides for post-disaster housing reconstruction published by international organisations. Through this analysis and discussion, it is concluded that prefabricated modular structures are a highly desirable time-efficient solu- tion to post-disaster housing reconstruction.

ItemAn Integrated Simulation and Visualisation Platform for the Design of Sustainable Urban Developments in a Peri-Urban Context(SPRINGER INTERNATIONAL PUBLISHING AG, 2016)Designing sustainable urban development is a multi-dimensional and multi-disciplinary challenge that can benefit from next-generation modelling tools to achieve high performance outcomes and integrated assessments. This chapter presents and demonstrates the use of ‘MUtopia’, an information modelling platform for assessing alternative urban development scenarios. The use of the platform is illustrated through the application to a peri-urban development in the city of Melbourne, Australia. The modelling platform allows simulation of various transition and future scenarios at the precinct level. The platform is capable of extracting data to assist in developing and assessing the performance of different components (land use, individual buildings and infrastructure related to energy and water supply and use, waste management and transport systems) by taking advantage of the platform’s unique scalability. The selected case study is a 31.5 ha Parcel of land, a typical peri-urban development in Melbourne’s fringe located in West Cranbourne. A key aspect of the development is the design of a sustainable precinct that is affordable, provides a greater level of amenity and incorporates biolink corridors and natural open spaces critical to the preservation of native biodiversity. As a low rise suburban development this project presents a unique opportunity for the application of the MUtopia platform and to demonstrate how the tool can lead to optimum design parameters for achieving sustainable development. This chapter also describes how MUtopia can be used to optimise the selection and design of sustainable and resilient energy, water and waste infrastructure and its integration with existing infrastructure.

ItemEffects of phase change material roof layers on thermal performanceof a residential building in Melbourne and Sydney(Elsevier, 2016-04-05)This paper assesses the effectiveness of Phase Change Materials (PCMs) for the improvement of the thermal performance and the thermal comfort of a residential building in Melbourne. The incorporation of PCMs in buildings with their significant heat storage capacity can delay the heat transfer and reduce the cooling and heating loads. Numerical simulation is a useful tool for comprehensive assessments and optimization of PCM applications in buildings. Thus an available TRNSYS component, PCM Wall: Type1270, was implemented with Type56 (Multi zone component). PCM Wall TRNSYS component has been validated with some experimental data published in the open literature. The validated model was then utilised to simulate the thermal performance of a residential building which has a PCM roof layer. The building is a typical single-storey, three bed room residential building in Melbourne. It was found that the PCM roof layer can reduce the cooling and heating loads whilst providing better thermal comfort for occupants with reduced indoor temperature fluctuations.
