Protecting civil engineering structures from uncontrollable events such as earthquakes while maintaining their structural integrity and serviceability is very important; this paper describes the performance of a stiffness softening magnetorheological elastomer (MRE) isolator in a scaled three storey building. In order to construct a closed-loop system, a scaled three storey building was designed and built according to the scaling laws, and then four MRE isolator prototypes were fabricated and utilised to isolate the building from the motion induced by a scaled El Centro earthquake. Fuzzy logic was used to output the current signals to the isolators, based on the real-time …

Illicit heroin use is a worldwide problem, with significant health and social costs. Treatment is known to be effective in changing heroin use habits, but it often needs to be provided over a lifetime, with people cycling in and out of treatment. It is therefore important to capture a long-term perspective on heroin use careers. The aim of this project was to build a lifetime microsimulation model of heroin using careers. This paper describes the conceptual logic of the model, the input parameters and the verification and validation results. A microsimulation model was chosen as the most appropriate simulation platform …

This paper proposes a novel rigorous transformation model for 2D-3D registration to address the difficult problem of obtaining a sufficient number of well-distributed ground control points (GCPs) in urban areas with tall buildings. The proposed model applies two types of geometric constraints, co-planarity and perpendicularity, to the conventional photogrammetric collinearity model. Both types of geometric information are directly obtained from geometric building structures, with which the geometric constraints are automatically created and combined into the conventional transformation model. A test field located in downtown Denver, Colorado, is used to evaluate the accuracy and reliability of the proposed method. The comparison …
Nano-Enhanced Phase Change Materials For Improved Building Performance, Zhenjun Ma, Wenye Lin, Mohammed I. Sohel
Nano-Enhanced Phase Change Materials For Improved Building Performance, Zhenjun Ma, Wenye Lin, Mohammed I. Sohel
Faculty of Engineering and Information Sciences - Papers: Part A
Nano-enhanced phase change materials (PCMs) have attracted increasing attention to address one of the key barriers (i.e. low thermal conductivity) to the wide adoption of PCMs in many industrial applications. This paper discusses the generic problem and key issues associated with appropriately using this new class of materials in buildings for effective thermal management and improved energy performance. An overview on major recent development and application of nano-enhanced PCMs as thermal energy storage media is provided. A case study based on a PCM ceiling ventilation system integrated with solar photovoltaic thermal (PVT) collectors is then performed to evaluate the potential …
Delivering Sustainable Building Projects - Challenges, Reality And Success, Haleh Rasekh, Timothy J. Mccarthy
Delivering Sustainable Building Projects - Challenges, Reality And Success, Haleh Rasekh, Timothy J. Mccarthy
Faculty of Engineering and Information Sciences - Papers: Part A
This research concerns the delivery of sustainable building projects. These projects are defined as those which either attempt to achieve green ratings or are claimed to address certain sustainability issues. A key focus is to examine how the client's vision for sustainability is achieved or compromised by the practicality of construction. Two sustainability rating systems, the Australian Green Star and the Living Building Challenge from the U.S. are discussed. This research examines two projects; one university multipurpose building (SMART Infrastructure Facility); and an advanced research facility, the Sustainable Buildings Research Centre (SBRC). The methodology used is semi-structured interviews of key …
Building Characterisation And Retrofit Decision Support-Tools For Upgrading Homes Of Low-Income Older Australians, Paul Cooper, Clayton Mcdowell, Michael P. Tibbs, Georgios Kokogiannakis, Laia Ledo Gomis, Stephen C. Choi
Building Characterisation And Retrofit Decision Support-Tools For Upgrading Homes Of Low-Income Older Australians, Paul Cooper, Clayton Mcdowell, Michael P. Tibbs, Georgios Kokogiannakis, Laia Ledo Gomis, Stephen C. Choi
Faculty of Engineering and Information Sciences - Papers: Part A
This paper describes the development and implementation of a comprehensive methodology to select and implement energy efficiency upgrades to the homes of low-income, older (>60 years) Australians. This work was conducted as part of a project entitled, 'Energy Efficiency in the 3rd Age (EE3A)", which targeted lowincome older residents in the Illawarra Region of NSW, Australia, and was funded by an Australian Federal Government 'Low Income Energy Efficiency Program (LIEEP)' grant for AUD2.3M. The project included a social marketing and behaviour change component engaging ~650 households, and a retrofit program for a subset of ~183 of these homes. Households …
A Bottom-Up Data Collection Methodology For Characterising The Residential Building Stock In Australia, Clayton Mcdowell, Georgios Kokogiannakis, Paul Cooper, Michael P. Tibbs
A Bottom-Up Data Collection Methodology For Characterising The Residential Building Stock In Australia, Clayton Mcdowell, Georgios Kokogiannakis, Paul Cooper, Michael P. Tibbs

In Australia the majority of the current residential building stock has been constructed with little regard to energy consumption or thermal comfort. With only 1-2 % of Australia's building stock being replaced each year retrofitting solutions are necessary if residential energy consumption is to be reduced. Australia's records of the characteristics of its current building stock are minimal and outdated and thus these need to be renewed to enable the evaluation of retrofit upgrade strategies. Thus this paper presents a methodology and results of a bottom-up data collection tool that captured building and occupant characteristics from 200 elderly low income …

Faculty of Engineering and Information Sciences - Papers: Part B
This paper describes a methodology for coupling an advanced model of the thermo-regulatory system of the human body that describes its physiological processes, a comfort model that evaluates thermal sensation and comfort, and the ESP-r building simulation software that computes the transient thermal response of a building model. The objective of this study was to utilise the physiology and comfort models to dynamically modify the heating and cooling temperature set points of a zone controller in ESP-r, in accordance with the computed human thermal sensation and achieve realtime thermal comfort management. The comunication between the software is managed by the …

Turkish Journal of Electrical Engineering and Computer Sciences
The importance of sustainable development and energy efficiency efforts has increased in the construction sector. Energy-saving efforts for buildings have become more important due to the global energy crisis, and energy rating systems have been developed globally for assessment of energy performance. In this study, international green building certificate and energy performance certificate (EPC) systems are presented. The official EPC system for buildings in Turkey is illustrated with case studies. Energy consumption and greenhouse gas emissions from residential buildings are calculated using the official national software, which is called BEP-TR. The impact of lighting on the total energy performance of …
