Improving Thermal Comfort In Naturally Ventilated University Buildings, Laia Ledo, Zhenjun Ma, Paul Cooper Jan 2012

Improving Thermal Comfort In Naturally Ventilated University Buildings, Laia Ledo, Zhenjun Ma, Paul Cooper

Faculty of Engineering - Papers (Archive)

A substantial fraction of Australian university buildings are naturally ventilated. These buildings consume a significant amount of energy and frequently suffer from overheating problems, resulting in poor indoor thermal comfort. This paper presents an investigation on the effectiveness of a range of energy conservation measures (ECMs) that can potentially be used to enhance energy performance and thermal comfort of these buildings. The ECMs considered in this study include information technology (IT) equipment and lighting upgrades, and measures focussed on occupant behaviour change. The effectiveness of each ECM was evaluated through modelling of a case study building at the University of …


Modelling Net Zero Energy Options For A Sustainable Buildings Research Centre, Paul Cooper, Xiong Liu, Prabuono Buyung Kosasih, Rui Yan Jan 2011

This paper describes the preliminary design and energy analysis of a university research building in NSW, Australia. This case study highlights some of the challenges confronting those wishing to design cost-effective net zero energy buildings in the Australian higher education sector and beyond. The Sustainable Buildings Research Centre (SBRC) is presently under development at the University of Wollongong and will be a unique building in the local region and an exemplar in respect of demonstration of a range of technical and operational means of reducing greenhouse emissions and other ecological impacts. This paper provides details on the constraints and opportunities …


Seismic History Analysis Of Asymmetrical Adjacent Buildings With Soil-Structure Interaction Consideration, Mehmet Uz, Muhammad N. S Hadi Jan 2011

Seismic History Analysis Of Asymmetrical Adjacent Buildings With Soil-Structure Interaction Consideration, Mehmet Uz, Muhammad N. S Hadi

The seismic response history analysis of multi-storey asymmetric adjacent buildings with soil-structure interaction (SSI) during impact is investigated in this study. The coupled multi-degree of freedom modal differential equations of motion for the two way asymmetric shear buildings are derived and solved using a step by step solution by the fourth-order Runge-Kutta method with impact and without impact. The SSI forces are modelled in the form of the frequencyindependent soil springs and dashpots. A numerical example of two-way asymmetric four-storey adjacent buildings under the variation of the important SSI system parameters such as the large and small SSI effects is …


Investigating The Effects Of Pounding For Inelastic Base Isolated Adjacent Buildings Under Earthquake Excitations, Mehmet Uz, Muhammad N. S Hadi Jan 2011

Investigating The Effects Of Pounding For Inelastic Base Isolated Adjacent Buildings Under Earthquake Excitations, Mehmet Uz, Muhammad N. S Hadi

Faculty of Engineering - Papers (Archive)

In this study, an investigation is carried out to analyse the earthquake induced pounding be-tween two insufficiently separated base isolated buildings considering the inelastic behaviour of the struc-tures’ response. The buildings are modelled as a four-story and a three-story system to simulate the structural behaviour. The resulting systems of second order constant coefficient equations are reformulated as a system of first order ordinary differential equations and solved using the ordinary differential equation solver of MATLAB. Numerical study revealed that pounding behaviour of the buildings has considerable influence on the behaviour of the lighter building causing substantial amplification of the response …


Protecting Low-To-Medium-Rise Buildings By Scrap Tyre-Soil Mixtures, Hing Ho Tsang, Nelson Lam, Saman Yaghmaei-Sabegh, M Neaz Sheikh, Wei Xiong, Shou-Ping Shang Jan 2009

Protecting Low-To-Medium-Rise Buildings By Scrap Tyre-Soil Mixtures, Hing Ho Tsang, Nelson Lam, Saman Yaghmaei-Sabegh, M Neaz Sheikh, Wei Xiong, Shou-Ping Shang

The stockpiling of scrap tyres is a significant threat to our environment and has been a hot topic amongst the engineering community which has been looking for long term viable solutions to the recycling and reuse of rubber. This paper proposes a new method of utilizing scrap tyres for applications in infrastructure protection forming part of the solution strategy. The method involves mixing scrap tyres with soil materials and placing the mixtures around building foundations, for vibration absorption. The potential of the proposed method will be demonstrated by numerical modelling to show its effectiveness and robustness as a means of …
