Talk Title: Sustainable Buildings – their performance in practice from the point of view of the occupants
Abstract: In his keynote address Prof Baird will summarise some of the main findings from a world-wide survey of the occupants of over 30 sustainability-credentialed commercial and institutional buildings located in a range of climatic zones.
The first part of the presentation will detail the distributions of the perception scores for each one of the forty-five aspects on which responses were sought from the occupants during the surveys. These distributions support the view that users are well able to assess variations in a wide range of aspects of the premises they occupy and that more systematic use should be made of their perception scores in building design and evaluation.
The second part will outline what features appeared to enhance the comfort, health and productivity of the occupants; and identify the ‘best’ and ‘worst’ buildings of those surveyed based on an index that takes account of 11 key variables.
His presentation will conclude with a discussion and summary of the design features associated with these results.
Bio: George Baird is Emeritus Professor of Building Science at the School of Architecture, Victoria University of Wellington, specialising in building environmental science and the assessment of building performance from the point of view of the users.
He is a Fellow of the Chartered Institution of Building Services Engineers (UK) and of Engineering New Zealand, and was awarded Life Membership of the Energy Management Association (now Carbon and Energy Professionals) of New Zealand in 2013.
He received the NZ Science and Technology Bronze Medal in 1999, the international “Pioneers of the World Renewable Energy Network” Award in 2006 and was appointed a Fellow of the Architectural Science Association at their 50th Annual Conference in 2016.
Dr. Baird has authored innumerable conference papers and journal articles over the last half century. Major books include: Energy Performance of Buildings; Building Evaluation Techniques; Architectural Expression of Environmental Control Systems; and most recently Sustainable Buildings in Practice, a worldwide survey of sustainable buildings.
Still active in his field, he was an invited speaker at the recent World Sustainable Building Conference in Hong Kong and the Passive and Low Energy Architecture Conference in Edinburgh, and is a member of the editorial boards of several journals in the field of architectural science, including Architectural Science Review, Journal of Building Engineering, Intelligent Buildings International, and Buildings.

Keynote Speaker II
Prof. Philip L-F. Liu
Class of 1912 Professor of Engineering Emeritus
Civil and Environmental Engineering, Cornell University, US
Bio: Philip L-F. Liu is the Class of 1912 Professor at Cornell University and is affiliated with the School of Civil and Environmental Engineering (CEE), the Center of Applied Mathematics and the field of Computational Sciences. Dr. Liu is also the holder of the Kwoh-Ting Lee Chair Professorship at the National Central University, Taiwan, where he is affiliated with the Institute of Hydrological and Oceanic Sciences. Currently, he is on leave from Cornell and is a Distinguished Professor in the Department of Civil and Environmental Engineering at the National University of Singapore (NUS). He is also serving as the Vice President for Research and Technology at NUS.
After graduating with a B.S. degree in Civil Engineering from National Taiwan University in 1968, Liu studied at Massachusetts Institute of Technology and received a S.M. degree in Civil Engineering in 1971 and a ScD degree in 1974. He joined Cornell faculty as an Assistant Professor in the School of CEE in 1974 and was promoted to Associate Professor in 1979 and Full Professor in 1983. He served as the Associate Director of the School in 1985-1986 and as the Associate Dean for Undergraduate Studies of Engineering College in 1986-1987. Liu was the Director of the School of CEE from July 1, 2009 to June 30, 2015.
Liu is an internationally-recognised, front-line researcher in the fields of water wave theory, tsunami dynamics, wave-breaking processes, sediment transport and the interaction of waves with structures. Since the 1990s, he has pioneered the development of a unified mathematical model of wave behaviour that covers a wide range of nonlinearity and frequency dispersion. The advances he has achieved have resulted, for the first time, in physically-based mathematical models and efficient computational procedures that produce accurate predictions of wave fields over complex bathymetry as well as in the vicinity of coastal structures. His reputation rests on the outstanding contributions he has made to fundamental understanding of wave processes and to the applicability of his research to practical engineering problems. For example, his recently-developed numerical model (CORBAS), which provides a detailed description of the generation and dissipation of turbulence energy by wave breaking, has been used around the world as a research and engineering tool to study and evaluate breakwater designs. His eminence in the field of nonlinear waves was recognised by his co-option to the US National Science Foundation (NSF) Task Force formed to assess the causes and consequences of the 2004 Asian tsunami and to the National Research Council (NRC) Committee to review the Louisiana Coastal Protection and Restoration (LACPR) Program.
Liu has co-authored one book and co-edited more than 10 books. His 200+ archival papers have received over 2800 citations. Liu is a Fellow of the American Geophysical Union (AGU) and the American Society of Civil Engineers (ASCE). He has received many academic awards, including the prestigious ASCE Walter L. Huber Civil Engineering Research Prize (1978), the J. S. Guggenheim Fellowship (1980), the ASCE John G. Maffatt & Frank N. Nichol Harbor and Coastal Engineering Award (1997), the International Coastal Engineering Award ASCE (2004) and the Alexander von Humboldt Research Award (2009). Liu was elected to the National Academy of Engineering (NAE) in 2015.

Speech Title: Migration Pattern of Liquid in Porous Soil Due to Earthquake Effect
Abstract: A rapid growth and development of country has contributed to the underground storage tank leakage and surface spillage of hydrocarbon liquid and industrial chemicals into the porosity subsurface. This led to groundwater contamination of liquid namely aqueous phase liquids (APL) and non-aqueous phase liquids (NAPL) which cause a harmful effect on the environment and health issues. A comprehensive understanding of contaminate migration is important to ensure the sustainability of geo-environmental and groundwater utilization. This keynote address is intended to make understand the phenomena and characteristic of APL and NAPL migrations in porous soil under earthquake effect and intact condition. A laboratory fluid migration model was simulated to show the effect of earthquake using double-porosity soil and its response using vibration table and accelerometer. The APL and NAPL migrate simulation results were obtained using digital image processing techniques. The recorded images were analyzed using Matlab special self-development routine and Surfer software to plot the hue saturation intensity (HSI) of the APL and NAPL migration characteristic. Similar method was deployed to develop a NAPL saturation calibration curve for verifying the hue values of the image to the actual NAPL saturation in fractured double-porosity soil. The multiphase flow and pollutant transport model for NAPL migration developed by Galerkin’s weighted-residual method was employed with the temporal discretization via implicit scheme. The simulated results using saturation calibration curve data compared to the works of previous researchers for validation purposes. The outcome shows that the deformable double-porosity soil has more fractured pores compare to the intact double-porosity soil. From the acceleration response analysis, it was seen that the soil samples has amplification and dis-amplification shaking. Thus, the fractured double-porosity soil has high permeability due to faster APL and NAPL migration and not uniformly downward due to the non-homogeneity of the fractured double-porosity under vibration process compared to intact double-porosity soil. The multiphase immiscible flow and pollutant transport model produce a faster penetration of NAPL in fractured double-porosity soil compared to intact double-porosity and single-porosity soil. In conclusion, it has shown that study can benefit researchers to comprehensively understand and simulate the liquids migration pattern that influence the groundwater resources. It is useful for future environmental sustainability of natural resources especially in susceptible earthquake zone area.
