Article
Building-integrated photovoltaics (BIPV) is an excellent renewable energy application for building envelopes. In Australia, BIPV roofing is considered to be promising because of recent major concerns about fire risks of façades. However, the integration of PV into building envelope elements is a complicated process which, if not done properly, may...
Article
The design of building-integrated photovoltaic (BIPV) envelopes involves a large set of envelope-related parameters, PV-related parameters and conflicting performance criteria. Therefore, optimization of BIPV design is crucial and it has become a complex process. Existing BIPV design optimization frameworks lack BIPV product and application type-re...

Commonly, this involves students engaging in learning experiences that involve real-world issues and which in turn enhance the student experience and employability...
Conference Paper
Full-text available
Risk perception is an antecedent to the conceptualisation of a risk control strategy. If project stakeholders do not perceive risks in a similar way, it is likely that they will have disagreement about how risks should be controlled and /or the adequacy of strategies developed to control these risks. If the disagreement is not understood and remain...

Participants were asked to sort photographs depicting different b...
Article
Full-text available
Traditional approaches in construction project management assign each process to a trade contractor with an individual specialisation, and trades with the greatest work content (bottlenecks) have a significant influence on the progress rate of projects. A system with integrated processes, however, is able to function dynamically in response to vari...
Article
Full-text available
Purpose – The purpose of this paper is to explore the relationship between the timing with which decisions are made about how to control work health and safety (WHS) risks in construction project (i.e. either pre- or post-construction) and the quality of risk control outcomes. Design/methodology/approach – Data were collected from 23 construction...
Article

To address this, the Australian construction industry and its regulator, the Office of the Australian Building and Construction Commissioner, have required that anyone who intends to work on a construction site must complete an Occupational...
Article
Full-text available
Preventing occupational health and safety (OHS) hazards through design is consistent with the principle that OHS is best managed by eliminating hazards at their 'source' rather than reducing risks that eventuate in the workplace. In 2007, an industry-initiated research and development project was undertaken in Australia to identify and document bes...
Article
Buildings are one of the major infrastructure investments in cities. Sustainable preservation of building assets in order to deliver an appropriate level of service throughout their life cycle requires a comprehensive and optimised decision making methodology. This decision making method needs to be supported not only by accurate data, but also by...
