On the Use of Relative Validity Indices for Comparing Clustering Approaches Open
Relative Validity Indices (RVIs) such as the Silhouette Width Criterion, Calinski–Harabasz and Davies-Bouldin indices are the most widely used tools for evaluating and optimising clustering outcomes. Traditionally, their ability to rank co…
Comparing clustering approaches for smart meter time series: Investigating the influence of dataset properties on performance Open
The widespread adoption of smart meters for monitoring energy consumption has generated vast quantities of high-resolution time series data which remain underutilised. While clustering has emerged as a fundamental tool for mining smart met…

A light-blocking greenhouse film differentially impacts climate control energy use and capsicum production Open
High-tech protected cropping holds great potential to improve global food security, but high cooling energy costs in warm climates pose difficulties in propagating the industry. Emerging technologies, such as diffuse glasses fitted with ph…
Real-time high-resolution modelling of grid carbon emissions intensity Open
Reducing greenhouse gas emissions in the energy industry is broadly acknowledged as important with numerous countries implementing targets to reduce emissions. Understanding the carbon emissions intensity of electricity grids is an importa…
Aggressive pre-cooling of an office building to reduce peak power during extreme heat days through passive thermal storage Open
Extreme temperatures can cause strain on electrical energy infrastructure. Additionally, network infrastructure and generators are sized for peak consumption. Hence, higher peak usage leads to higher electricity costs to build and maintain…
A smart building semantic platform to enable data re-use in energy analytics applications: the Data Clearing House Open
Systems in the built environment continuously emit time series data about resource usage (e.g., energy and water), embedded electrical generation/storage, status of equipment, patterns of building occupancy, and readings from IoT sensors. …
Energy flexibility of commercial buildings for demand response applications in Australia Open
Demand response (DR) is widely recognized as an important mechanism in the Australian electricity market, though large-scale uptake in commercial buildings is yet to occur, in part due to the difficulty of characterising the resource. This…
Cloud-based model-predictive-control of a battery storage system at a commercial site Open
Reducing costs for battery energy storage systems and the increasing availability of onsite generation sources are driving development of complex battery control algorithms principally aimed at minimising electricity costs. These algorithm…

A novel cover material improves cooling energy and fertigation efficiency for glasshouse eggplant production Open
Glasshouses hold the potential to improve global food security, but high energy costs are an ongoing challenge in bringing them to the forefront of agriculture in warm climates. Here, the energy-saving potential of a ‘Smart Glass’ (SG), di…
Role of sustainable heat sources in transition towards fourth generation district heating – A review Open
As an integrated part of future sustainable energy systems, district heating has been widely established as a convenient solution to provide energy-efficient space heating and sanitary hot water. In the pathway towards decarbonization of d…
Towards a Residential Air-Conditioner Usage Model for Australia Open
Realistic models of occupant behaviour in relation to air-conditioner (a/c) use are fundamentally important for developing accurate building energy simulation tools. In Australia and elsewhere, such simulation tools are inextricably bound …
