Preface Thermal manikins are essential tools for the objective and accurate assessment of thermal comfort or stress. They are particularly useful for investigations under harsh conditions that simulate extreme environments such as wind blown mountaintops, scorching deserts or even hostile space, but also indispensable for the development of functional clothing (e.g. sportswear, protective clothing, army uniforms) and HVAC (i.e. heating, ventilation and air-conditioning) systems for the creation of safer and more comfortable living. Along with the development of thermal manikins, modelling of the human body, clothing and environment system is also very important as it enables us to predict human performance in different conditions. This volume contains papers presented at the sixth international thermal manikin and modelling meeting (6I3M) held in Hong Kong from 16th to 18th October 2006. These papers cover different aspects of thermal manikin and modelling including early development history, current original researches, improvements in standardization and innovative applications. This book is an essential reference for research scientists, technologists, safety engineers, product developers and health care professionals as well as students in the areas of environmental ergonomics, functional clothing, thermal engineering and occupational safety. I would like to take this opportunity to thank members of the Board of Scientific Program Committee of 6I3M for their academic leadership and invaluable advice. I also wish to express my sincere gratitude to the Institute of Textiles and Clothing (PolyU), Hong Kong Research Institute of Textiles and Apparel, and Modern Testing Service Ltd for their generous sponsorship to the Meeting. I am also indebted to Prof. L. Hunter of CSIR, South Africa for proofreading and editing the writing of all the manuscripts. Last but not least, I would like to thank members of the organizing committee, especially Lydia Fung, Cathy Tsang and the Apparelkey team for the dedication in organizing the event.
