ItemThe Shanghai Paradox(Architecture Media Politics Society, 2014)This paper outlines my ongoing research on the use of traditional symbolism and its utilisation in contemporary architecture of the Chinese global city. It specifically examines the landmark architecture of the Pudong, or the “new” Shanghai. Is there a contradiction in imagery when architects adopt traditional motifs in contemporary skyscraper architecture? Designs such as Cesar Pelli’s Petronas Towers (1994) in Kuala Lumpur use traditional Islamic patterns in the floor plans and façade detail. However, in the case of Shanghai, the three landmark buildings of the Pudong as shown in Figure 1; the Jin Mao Tower (1999), the Shanghai World Financial Centre (2008) and the Shanghai Tower (under construction at the time of writing), all reference fengshui and cosmology. The paradox in this case is that under law of the People’s Republic of China (PRC), geomancy, including fengshui and cosmological symbolism, is defined as a feudal superstition and its practice illegal.

ItemArchitectural specialisation and the death of architectural practice(Architectural Science Association & The University of Adelaide, 2016)In the past 50 years the traditional role of the architect to supervise and control projects has been eroded. The last remaining bastion maintain this traditional role of the architect is in small practice. Using a survey that firstly looks at how architects are engaged via either full or partial services we explore how architects identify with and deliver specialised services. The respondents in the survey were taken from a sample of 1200 Australian architects. Data was collected regarding specialisation, service provision, outsourcing and contractual arrangements. This is positioned alongside a historical account of the profession which suggests that technology and changes within legal frameworks, strategy, marketing, operations, project management, and finance are leading to the marginalisation of architects. We test this assertion by investigating evidence for these changes and the extent to which specialised architectural knowledge is being created in firms. For architects, specialist architectural knowledge is integrative and resides in the traditional service delivery particularly in the realm of housing. However, fee competition has hampered the ability of architects to specialise. As a result, in the future the role of the architect may be non-existent.

ItemDeveloping An Evidence-based Understanding of Hospital Space Planning Efficiency(Architectural Science Association, 2018)Over the last two decades there has been a steady increase in the demand for healthcare services and a commensurate rise in the global expenditure in health (WHO, 2014). Given the significance of the financial investment in capital works programmes required to meet growing healthcare needs and the expanding environmental impact of the healthcare industry, it is important to gain a detailed understanding of how healthcare infrastructure assets currently perform, the strategic drivers impacting on hospital space use efficiency, and the complex interrelationship of factors that impact on the healthcare environment. This paper outlines a research project that was conducted by the University of Melbourne in conjunction with a local architectural practice partner, to examine space planning efficiency and emerging trends in hospital space planning requirements. To assist in developing a greater understanding of the space planning efficiency of healthcare infrastructure, and changing trends in hospital space planning, this study examined a range of measures across 31 hospitals against regional and international benchmarks. This paper outlines a novel multi-modal research methodology established to examine the complex range of interconnecting planning measures impacting space planning efficiency, and some of the difficulties in assessing hospital space planning efficiency.

ItemAll that glitters is not gold: the effect of mining activities and royalties on the built environment of remote North East Arnhem Land(Society of Architectural Historians, Australia and New Zealand (SAHANZ), 2016)This paper explores the effects of mining activities and royalties on the Northern Territory’s remote northeast Arnhem Land region, including the mining town of Nhulunbuy (with a 93.8% non-Indigenous population) and surrounding Indigenous communities, and shows that the associated architectures do not provide long-term benefit to local people. In 2014, Rio Tinto Alcan closed their alumina refinery in Nhulunbuy. This resulted in the redundancy or redeployment of 1100 workers and a significant reduction in the town’s 4000 strong population. The closure of the refinery calls into question the role of mining settlements and their surrounding regions beyond the life of a mine. Using the case study of northeast Arnhem Land, the paper describes the genesis of the Nhulunbuy Township in the late 1960s and how it precipitated the Indigenous land rights movement in the Northern Territory and the repatriation to homelands throughout the region. The paper analyses the architecture of Nhulunbuy, whose public, commercial and residential buildings were almost exclusively designed and built by the mining company, in comparison to the architectures that emerged through mining royalty funds distributed to traditional land owner groups such as the Gumatj and Rirratjingu Aboriginal Corporations, the Yirrkala Dhanbul Association and the Arnhem Land Trust. It historicises and critiques their respective contextual response to environmental, social and adaptive economic factors. Nhulunbuy has grown to become a significant resource centre for the northeast Arnhem Land region providing services to surrounding Indigenous communities and homelands. Thus the paper turns to a discussion of the recent history of the alumina refinery closure and the subsequent ramifications for the region’s architecture, both in the mining town and for mining royalty funded structures throughout the region. With the sudden closure of other mines throughout remote Australia, such as the Alinta coal mine at Leigh Creek, South Australia, which also acts as a service centre to the nearby Iga Warta Indigenous community, this paper is both a timely and relevant contribution.

ItemStructural Design with Reclaimed Materials: an Elastic Gridshell out of Skis(International Association for Shell and Spatial Structures (IASS), 2017)This paper presents the design and construction of a 36m2 gridshell, the rigidity of which is achieved through the bending of an initially flat grid of 210 reclaimed skis. The generated waste for its production is near zero as it is mostly built from discarded material. Its construction process is such that it can be disassembled and reassembled multiple times without scaffolding and by means of traditional tools only. After a brief introduction on the need for reducing embodied carbon and waste in structures through reuse, the paper sets up the constraints that have driven the definition of the pavilion, the main one being the extension of the lifetime of high-performance sport equipment by reclaiming their intrinsic mechanical properties. The paper then details the encountered unusual aspects in the design process and how they have been overcome – i.e., sporadic material supply, categorization of mechanical properties, physical alteration of these properties, and uncertainties in the numerical modelling of both the structural analysis and the construction process. Eventually, we conclude that reclaimed skis as a material have the potential to be as good as conventional timber when designing elastic gridshells. A series of future directions for this emerging field of research are also laid out.

ItemThe lIfe cycle performance of Monomur in Australian residential construction(Green Building Council Spain, 2014)Brick veneer is the most dominant construction type in Australia; however it is not necessarily the most advantageous for the climate. Mass wall types, where massing is evident on the interior of the building, can help to achieve greater thermal performance. Monomur thermal blocks are a thermal mass system, based on single leaf construction. They are resistant to compression, transfer of heat, and are made from natural clay. Monomur has shown to benefit construction in Europe, most predominantly France, where the push for low energy buildings is high on the national agenda. This study aimed to determine the life cycle energy performance of the use of the monomur system in Australian residential construction. A life cycle energy analysis (LCEA) was used to quantify and compare the life cycle energy performance of two case study houses, one built from monomur and one from brick veneer. It was shown that there is minimal difference in the performance of these two construction approaches, paving the way for the potential use of monomur in the Australian context.

ItemAn early-stage life cycle model for low-energy buildiings(Green Building Council Spain, 2014-10-30)The aim of this study is to demonstrate the application of a model previously developed by the authors for low-energy building design, to show how the availability of comparable energy performance information at the building design stage can be used to better optimise a building’s energy performance. The life cycle energy demand of a case study building was quantified using a comprehensive embodied energy assessment technique and TRNSYS thermal energy simulation software. The building was then modelled with variations to its external assemblies in an attempt to optimise its life cycle energy performance. The alternative assemblies chosen were those shown through the authors’ early-stage life cycle energy model to result in the lowest life cycle energy demand for each building element. The study showed that significant life cycle energy savings, up to 45%, are possible through the modelling of individual building elements for the case study building.

ItemConcept and barriers for the economic value of low-energy houses(Royal Institution of Chartered Surveyors, 2015)This study explores the market revealed price of low-energy residential buildings and why the economic value of low-energy housing products is less transparent in active residential markets. It explores Australian and Japanese conditions and examines the proposition by using embodied energy, operational energy and market price data of selected housing stock in Australia. The study aims to examine a new perspective towards understanding the barriers to ascertaining the economic value of low-energy buildings. In particular, the study examines the composition of energy consumption associated with the residential property life cycle. Operational energy is linked to consumer preference by its inter-temporal value estimate of future expected utility or benefit flow. A ‘low’ embodied energy house is an environmental construct, which does not appear to currently link to short-term market value perception. It does not strongly link to an expected (intuitive) benefit. This ‘gap/disconnect’ creates a barrier to estimating a holistic economic value of low-energy residential property.

ItemExploring the relationship between Melbourne’s water metabolism and urban characteristics(State of Australian Cities Research Network, 2015)Cities can be seen as complex urban systems that mobilise local and global resource flows to meet the needs of their inhabitants and their manufacturing sector. However, the local consumption of resources can be responsible for major local and global environmental changes that impact the human health and wellbeing inside and outside of the boundary of the urban system. With global urban population expected to continue to grow, the mitigation of further future environmental pressures from urban consumption is of critical importance. The complexity of the interrelationships between the local social, political, cultural, economic and environmental facets of a city as well as the interrelationship between these local characteristics and urban consumption, dictate that each city will have a different set of parameters that drive urban consumption. This research will investigate this issue by exploring the relationship between Melbourne’s water metabolism and its urban characteristics. In practice, this study will correlate the spatially disaggregated water use of Melbourne with local factors such as demography, average income, territorial organisation, etc. It will then be possible to identify which urban characteristics have the greatest influence on water use and ultimately help to inform the development and implementation of the most appropriate and best targeted policies for reducing water use across Melbourne Metropolitan Area.

ItemVentilation for Reduced Heat Stress in Apartments(The Architectural Science Association (ANZAScA), Australia, 2017)The increase in building code requirements of modern buildings are correlated with increased overheating, particularly in apartment buildings. This research addresses the comparative performance of the Australian apartment stock with international heat wave regulations, six apartment buildings were performance modelled based on the extremes of the 2009 Victorian heatwave that began on the 27 January with daytime temperatures topping 43°C across 3 days, with night‐time minimums of above 25°C. All 6 apartments failed the four international summer comfort standards that were reviewed. The worst performing apartment underwent further investigation. Retrofit strategies were tested to determine the most effective method for reducing overheating. As found in the literature, improved ventilation is often the most effective retrofit method. Further investigation revealed that ventilation opportunities are significantly restricted by the Australian NCC window protection requirements that restrict window openings, reducing typical ventilation area from a window from 50% to 20%. This has a significant impact on the ability to use natural ventilation for reducing of overheating in apartments.
