The results will provide a useful benchmark and a guide to the potential of environmentally sustainable property development.Read moreRead less
Impact and Effectiveness of Personal Ventilation in Open Plan Offices: a study of the Task Air system. Centralised air-conditioning systems are the standard for commercial office buildings in Australia. These systems are energy intensive, typically accounting for around 50% of building energy use. However, lack of occupant control over set temperatures or air movement tends to reduce thermal comfort, which can adversely affect worker productivity. The benefit of this project is that it will qu ....Impact and Effectiveness of Personal Ventilation in Open Plan Offices: a study of the Task Air system. Centralised air-conditioning systems are the standard for commercial office buildings in Australia. These systems are energy intensive, typically accounting for around 50% of building energy use. However, lack of occupant control over set temperatures or air movement tends to reduce thermal comfort, which can adversely affect worker productivity. The benefit of this project is that it will quantify the improvements to occupant comfort and energy savings possible with a PV system. This study will enable PV systems to be evaluated as an alternative to traditional air-conditioning, thereby demonstrating their effectiveness as a means of improving the sustainability rating of commercial office buildings in Australia.Read moreRead less
Open-plan Office Concepts Determine Effective Facilities Space Management. Open-plan layout is the most predominant work-setting and office designs are changing substantially towards this style. This research addresses the question, "How do open-plan attributes affect effective facilities space management." While this layout is increasingly adopted, no research has definitively answered this question or evaluated open-plan design for its usefulness. This research therefore aims to respond to thi ....Open-plan Office Concepts Determine Effective Facilities Space Management. Open-plan layout is the most predominant work-setting and office designs are changing substantially towards this style. This research addresses the question, "How do open-plan attributes affect effective facilities space management." While this layout is increasingly adopted, no research has definitively answered this question or evaluated open-plan design for its usefulness. This research therefore aims to respond to this question and establish reliable criteria for effective management and re-engineering of offices with open-plans. This research is novel and timely since it endeavours to develop new models and objective criteria to better exploit this concept for greater office performance and productivity.Read moreRead less
Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships ....Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships between specified concrete properties and performance. Through a systematic experimental and theoretical study, the behaviour of anchor regions of these slabs, including the reasons for failure will be investigated.Read moreRead less
Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popula ....Seismic performance of concrete beam-slab-column systems constructed with a re-useable sheet metal formwork system. When designing for earthquake induced loading it is very important to know the ductility and any other inherent deficiencies in structural systems under lateral deflections. The main purpose of this application is to investigate the seismic performance of an efficient beam-slab-column system constructed with a re-useable sheet metal formwork system, Corcon, which is becoming popular in Australia and overseas. The proposed research will ultimately lead to revised design guidelines for these systems, suitable for local and overseas practice where different levels of seismicity occur.

Fire Risk Evaluation of Commercial Buildings. An integrated systems risk-based model for fire safety has been developed for apartment buildings. A risk-based model must also be developed for commercial high-rise buildings taking into account the sub-models most relevant for these buildings. This requires a new approach and the development and integration of new submodels. Such a model does not currently exist but its development will allow for the cost-effective design of commercial buildings wh ....Fire Risk Evaluation of Commercial Buildings.

This requires a new approach and the development and integration of new submodels. Such a model does not currently exist but its development will allow for the cost-effective design of commercial buildings whilst still maintaining appropriate levels of fire safety.Read moreRead less
Embodied energy modelling of individual commercial buildings. This research will develop a method for modelling the energy embodied in individual commercial building construction. Construction material manufacturing emissions are well known in most industries, but the total embodied energy of the construction supply chain is difficult to model for individual buildings. For efficient commercial buildings, the embodied energy can represent up to 40 years of operational energy. The results will be ....Embodied energy modelling of individual commercial buildings. This research will develop a method for modelling the energy embodied in individual commercial building construction. Construction material manufacturing emissions are well known in most industries, but the total embodied energy of the construction supply chain is difficult to model for individual buildings. For efficient commercial buildings, the embodied energy can represent up to 40 years of operational energy. The results will be used to develop cost effective strategies for optimising the total life cycle energy of individual commercial buildings. This will in part improve the environmental performance of the Australian construction industry.Read moreRead less
Using global optimization technique to determine the most efficient use of building/floor space to accommodate a given office design. The commercial property market is one of the largest business markets, both in Australia and globally. Businesses of all kinds use commercial office space, which represents many billions of investment dollars.

Historically, ....Using global optimization technique to determine the most efficient use of building/floor space to accommodate a given office design. The commercial property market is one of the largest business markets, both in Australia and globally. Businesses of all kinds use commercial office space, which represents many billions of investment dollars. A better understanding of what constitutes efficient and effective office space would produce enormous commercial benefits for this country. Historically, very little (if any) consideration has been given to the efficiency of office space design. The measurement of efficiency has now become an essential component of 'site selection'. To date, the application of optimization methodologies have not been applied to the architectural industry, making the development of tools to address this problem a significant and innovative move.Read moreRead less
Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specificat ....Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specifications. This is due to the limited understanding of wind-induced fatigue of cladding. This project will provide the framework for understanding and minimizing cladding fatigue. A realistic single test will also reduce cost and result in better design systems.Read moreRead less
