A major problem in light-weight timber floors is their insufficient performance coping with impact noise in low frequencies. There are no prefabricated solutions available in Australia and New Zealand. To rectify this and enable the implementation of lig...
There has been no research to date exploring whether timber products can provide effective thermal capacitance in residential or commercial construction. This research is exploring the use of unique mass-timber products to provide a new form of thermal performance capacitance
within the built fabric of new and existing homes. The development of mass timber products is a new paradigm in material and building science research in Australia, requiring the accounting for carbon emissions, carbon sequestration, material embodied energy and material thermal properties for this renewable resource. This paper focuses on the results from preliminary building simulation studies encompassing house energy rating simulations and a comparative analysis of embodied energy and carbon storage for a series of house plans in Australia.
This study compares the life cycle environmental impacts of two multilevel residential buildings built in Melbourne, Australia. The study was commissioned by Australand and funded by Forest and Wood Products Australia (FWPA).
The first building considered, the ‘Study Building’, incorporated an innovative light weight building approach utilising a stick-built timber frame and a ‘cassette floor’ building system. The second building, the ‘Reference Building’ utilised a more typical building approach, incorporating precast concrete panels and suspended concrete slab floors (Table 1).
The primary goal of the study was to compare the potential environmental impacts of the above buildings across their respective life cycles.
The study employed the LCA methodology described by the ISO14044 standard to undertake the comparison of the buildings. The analysis addressed a building life cycle scope which was prescribed by GBCA (GBCA 2014), which in turn based the boundary definition on the EN15978 standard, as shown in Figure 1. Although EN15978 was used to define the scope of the LCA, the study is not intended to be fully compliant with the standard.
Following on from the author’s recently completed doctorial research investigating Scandinavian industrially produced engineered construction methodologies and their potential application in Australia, this paper reports on the research and development...
The present paper is the first to conceptually assess the viability of mass timber construction (MTC) as an alternative construction material/method in Australia. It fulfills an identified need to examine an innovative construction process providing much needed information concerning the technologies current position and future disruption to traditional construction methods. A common tool used in business management studies, the PESTEL model, Political, Economic, Social, Technological, Environmental and Legal is employed to provide structure for a strategic analysis of the technology. Mass timber construction clearly demonstrates some advantages including cost savings, primarily in the reduction in on-site labour costs; a lower environmental impact and use of a renewable resource; and possibility of improved amenity and reduced running costs for owners and occupiers. The estimated market potential for MTC in Australia indicates that a local plant might be viable as the market grows, and warrants funding to underpin a full feasibility assessment.
Wood-based mass-panels (WBMP) are emerging as an attractive construction product for large-scale residential and commercial construction. Australia is following the lead of Europe and North America with several recent projects being completed using predominately cross-laminated timber panels (CLT). These sawn timber-based panels offer some key advantages to the construction and sawmilling industry. However, veneer-based mass-panel (VBMP) systems could offer additional benefits including the more efficient use of the available forest resources to produce WBMPs that have equivalent to superior performance to CLT. Research to confirm the expected technical viability of veneer-based systems is required. VBMPs could provide a valuable contribution, alongside CLT, to the Australian timber products market.
