Technical development for deconstruction management

The Australian construction industry, particularly in the area of demolishing existing facilities, is responsible for up to 40% of the country's enormous solid waste streams, totalling about 14 million tonnes annually. The recently created concept of deconstruction, rather than destruction for demolishing a constructed facility, came about because of the rapidly increasing number of demolished buildings and changes in levels of environmental awareness. However,  reconstruction processes are now seen as only an interesting concept for reducing waste through reuse and recycling, but they fail to achieve widespread understanding or acceptance. The challenges faced by deconstruction are significant and diverse. The maturity of deconstruction practice depends on not only on tlle development of deconstruction techniques and management, but also on the enhancement of deconstruction awareness by the owners, designers, and construction teams, as well as the development of environmental regulations. These practical limitations are interrelated and mutually promotional. The technical developments in deconstruction management resulting from this research will have direct effects on various aspects, including the development of design and construction for deconstruction, deconstruction technology, reused material certification, recycl ing technology, and a method by which to calculate environmental benefits so that deconstruction would be promoted from an interesting concept mainly in theory to wide acceptance in practice. 

Information technology applications for planning in deconstruction

In recent years, there has been obvious emphasis on the shift from design and construction of new facilities to maintenance, refurbishment, and demolition management of existing facilities. Demolition technology has gradually changed from conventional destruction to the recently developed deconstruction. Demolition management, particularly deconstruction management, is becoming a novel, but a fertile teaching and research discipline. This paper focuses on an important issue of deconstruction management, how to work out a deconstruction plan using information technologies.

Waste production simulation for building deconstruction projects

The recently erected concept of building deconstruction has significantly promoted building components and materials reuse and recycling where building is carefully dismantled into reusable parts. Current research and practices of building deconstruction mainly focus on issues of process before and during the deconstruction such as hazardous material detection, deconstruction design and deconstruction technology. The issues after the deconstruction project are rarely considered. Waste reuse and recycling are enabled through deconstruction yet not practically achieved, and especially the demands of waste building components and materials are hard to appear and match the actual waste production in a building deconstruction project. To deal with this awkward situation, the waste production needs to be conducted in a demand-oriented way. It needs to be thoughtfully planned and scheduled prior to the physical deconstruction as an essential portion of deconstruction project planning and scheduling. Furthermore, the relationship between waste production and structural characteristics of the building creates a serious consideration affecting a deconstruction plan. As a result, a waste production simulation will facilitate waste reuse and recycling in a deconstruction project. It serves as a crucial section of deconstruction planning and design. This research aims to describe the concept of waste production simulation and investigate various management and technical aspects of waste production simulation for building deconstruction projects.

Re/de/signing the world : postructuralism, deconstruction and 'reality' in outdoor/environmental education research

This paper examines rhetorical constructions of ‘reality’ in selected outdoor/environmental education discourses-practices.1 Many outdoor/environmental educators privilege philosophical realism coupled with suspicion towards poststructuralism(s) and deconstruction. From a postlogographic position on language, we argue that producing texts is a method of inquiry, an experience and performance of semiosis-in-use as we sign (and de/sign) the world into existence. This re/de/signed world never represents the ‘real’ world precisely or completely, and in this paper we explore and enact modes of textual (and extratextual) production that struggle to retain a poststructuralist skepticism towards representational claims without falling into antirealist language games. We focus in particular on Deleuzean concepts of ‘rhizomatic’ inquiry and nomadic textuality as enabling dispositions for re/de/signing worlds in which realities and representations are mutually constitutive (rather than dialectically related).

Green roof retrofit potential in the central business district

Purpose – The purpose of this paper is to illustrate the potential for green roof retrofit to commercial buildings in a city centre to property managers and other property professionals.

Design/methodology/approach – This paper addresses the research question: what is the potential of existing buildings in the CBD to accommodate a retrofitted green roof? Furthermore, it questions how many buildings are suitable for green roofs? The researchers compile a unique building database incorporating information about 536 commercial buidings and evaluate the potential suitability of each building to undergo a green roof retrofit. Assisted by other commercially available databases and software, the researchers are able to assess each roof based on criteria derived from an extensive literature review.

Findings – A relatively small proportion of roofs are found to be suitable, partly a result of local climate conditions and rainfall patterns, and the physical property stock. On a purely physical assessment, only a very small proportion of CBD stock is found to be suited. These buildings are most likely to be in low secondary locations, ungraded or B grade buildings, privately owned, concrete framed and not overshadowed by adjoining properties.

Practical implications – Property managers and other property professionals can now determine the potential of their portfolio stock for green roof retrofit based on the review of building attributes required for success adaptation in this paper. It possible that greater potential for green roof retrofit exists in the suburbs or regional towns where lower rise buildings may reduce the amount of overshadowing found in city centres. Follow-up research could focus on a comparison of regional and suburban developments.

Originality/value – This is the first study of its kind and has assessed such a large number of buildings for their suitability for green roof retrofit; the findings provide a reliable guide for policymakers regarding the potential number of city centre buildings which would be possible to retrofit. Such findings should influence policymaking and incentives to target effective sustainability policies with regards to existing buildings.

Inventing (a) life: deconstruction and the praxis and poiesis of narrative

Deconstruction often sits awkwardly between the realm of literary studies and criticism, and philosophy proper. This paper explores the contribution that a deconstructive literacy might have for those engaged in writing narrative, as a practice and a product. Taking up Kristeva's reading of Arendt, and the Aristotelian categories of praxis and poiesis, it will be argued that the act of narrating life amounts to both the actual generation of the life it purports to describe, while also being a praxis in itself, one that need not produce anything, since the very act of engaging in/with it, leaves atraceless trace that itself is 'full of meaning'. Narrative, however, will not rest in either pole of Aristotle's binary structure. For Arendt, Kristeva will remind us, narrative is an activity that is very 'human', where we engender not just zoe, mere physiological life, but bios, a living that is not colonised by ends alone, and instead finding in itself a value, a fulfilment in its own process. Applied to the activity of story-making (autobiographical or otherwise), and also to pedagogical practice in the academy, this dual potential of narrative (at once to produce and to be an end unto itself) reframes the Beruf (calling) of creative writing. Deconstruction, in other words, assists us in appreciating the very ethical consequences of the labour of deciding where and when the story begins and ends, and who the protagonist is. Recalling us to the ontological implications of the thought of différance, this paper will attempt to demonstrate how the action of articulating the edges of story can be read as akin to that which turns the
featureless flux of time into bios, or human life that, according to Arendt, is what goes missing under totalitarianism.

Boats on the roof of the house: the shadowy flux of alterity

Freud’s ‘The Interpretation of Dreams’ focuses upon the relationship between the signs, in the surface content of the dream, and the operation of thought that produces these signs, in the latent content of the dream. Freud’s analysis is a means for tangling with a discontinuous narrative style because Freud’s analysis provides a methodological approach to the question: how does the novel bear witness to the writer’s subjective consciousness?

Integration of roof-top solar photovoltaic systems into the low voltage distribution network

The advancement in solar photovoltaic (PV) technology, the cost and efficiency of PVs have encouraged users worldwide to adopt more and more PVs as it is free from greenhouse gas emissions and unlimited in nature. Integration of roof-top solar PV systems is currently emerging rapidly in Australia as the governments are giving attractive incentives and encouraging households to build a sustainable climate-friendly society for the future. The key major barriers to the integration of roof-top solar PV systems are the uncertainties in the performance of the low voltage distribution network due to the intermittent nature of solar PV sources. In this paper, a model was developed to investigate the potential technical impacts of integrating roof-top solar PV systems into the low voltage distribution network in a subtropical climate. The results show that integration of roof-top solar PV in the customer premises causes uncertainties such as voltage fluctuations, phase unbalance, distribution transformer overloading, reactive power compensation, and harmonic injections that detract the overall power quality of the typical distribution network. © 2014 AIP Publishing LLC.
