Gassmann, H. Meixner Copyright © 2001 Wiley-VCH Verlag GmbH ISBNs: 3-527-29557-7 (Hardcover); 3-527-60030-2 (Electronic) As the use of microelectronics became increasingly indispensable in measure- ment and control technology, so there was an increasing need for suitable sen- sors. From the mid-Seventies onwards sensors technology developed by leaps and bounds and within ten years had reached the point where it seemed desirable to publish a survey of what had been achieved so far. At the request of publishers WILEY-VCH, the task of editing was taken on by Wolfgang Göpel of the Univer- sity of Tübingen (Germany), Joachim Hesse of Carl Zeiss (Germany) and Jay Ze- mel of the University of Philadelphia (USA), and between 1989 and 1995 a series called Sensors was published in 8 volumes covering the field to date. The material was grouped and presented according to the underlying physical principles and reflected the degree of maturity of the respective methods and products. It was written primarily with researchers and design engineers in mind, and new devel- opments have been published each year in one or two supplementary volumes called Sensors Update. Both the publishers and the series editors, however, were agreed from the start that eventually sensor users would want to see publications only dealing with their own specific technical or scientific fields. Sure enough, during the Nineties we saw significant developments in applications for sensor technology, and it is now an indispensable part of many industrial processes and systems. It is timely, therefore, to launch a new series, Sensors Applications. WILEY-VCH again commis- sioned Wolfgang Göpel and Joachim Hesse to plan the series, but sadly Wolfgang Göpel suffered a fatal accident in June 1999 and did not live to see publication. We are fortunate that Julian Gardner of the University of Warwick has been able to take his place, but Wolfgang Göpel remains a co-editor posthumously and will not be forgotten. The series of Sensors Applications will deal with the use of sensors in the key technical and economic sectors and systems: Sensors in Manufacturing, Intelligent Buildings, Medicine and Health Care, Automotive Technology, Aerospace Technology, Environmental Technology and Household Appliances. Each volume will be edited by specialists in the field. Individual volumes may differ in certain respects as dic- tated by the topic, but the emphasis in each case will be on the process or system in question: which sensor is used, where, how and why, and exactly what the ben- efits are to the user. The process or system itself will of course be outlined and V Preface to the Series Sensors in Intelligent Buildings. Edited by O. Gassmann, H. Meixner Copyright © 2001 Wiley-VCH Verlag GmbH ISBNs: 3-527-29557-7 (Hardcover); 3-527-60030-2 (Electronic) the volume will close with a look ahead to likely developments and applications in the future. Actual sensor functions will only be described where it seems neces- sary for an understanding of how they relate to the process or system. The basic principles can always be found in the earlier series of Sensors and Sensors Update. The series editors would like to express their warm appreciation in the col- leagues who have contributed their expertise as volume editors or authors. We are deeply indebted to the publisher and would like to thank in particular Dr. Peter Gregory, Dr. Jörn Ritterbusch and Dr. Claudia Barzen for their constructive assis- tance both with the editorial detail and the publishing venture in general. We trust that our endeavors will meet with the reader’s approval. Oberkochen and Coventry, November 2000 Joachim Hesse Julian W. Gardner Preface to the SeriesVI In the building control industry, a clear trend towards more ‘intelligence’ can be observed. In the last two decades, intensive research has been done in the area of intelligent buildings. The concept integrates new technologies from areas such as sensor systems, computer automation, space-age materials, and energy manage- ment in order to adjust and adapt to its occupants. Integrated sensor systems judge indoor and outdoor conditions of a building and its devices in order to oper- ate as an integrated system for maximum performance and comfort. Modern buildings become a place of multilateral interaction between the inhabitants and the building entities. With this volume Sensors in Intelligent Buildings of the series Sensors Applications the Editors aim to create a work that presents the reader with a competent and comprehensive survey of sensors and sensor systems currently applied in the building industry. The book is primarily aimed at scientists and engineers en- gaged in research on and the development and application of sensors and search- ing for detailed references on sensors in the building control area. New system so- lutions and a wide variety of sensors will be available in all building areas such as energy, HVAC, information, transportation, safety, security, maintenance, and fa- cility management. The chapters have been contributed by leading scientists in international re- search institutes, universities, and companies such as the City University of Hong Kong, Coactive Networks, University of Applied Sciences Dortmund, Estia Sàrl, Fraunhofer Institute for Computer Graphics Research, Fraunhofer Institute for In- formation and Data Processing, Fraunhofer Institute of Microelectronic Circuits and Systems, GMD Institute for Secure Telecooperation, Motorola, Philips Re- search Laboratories, Purdue University, San José State University, Sauter, Schind- ler Elevators & Escalators, Siemens Building Technologies, Siemens Corporate Technology, Siemens Energy & Automation, Siemens Landis & Staefa Electronic, Swiss Center for Electronics and Microtechnology (CSEM), Swiss Federal Institute of Technology (EPFL), The Media Laboratory, Massachusetts Institute of Technol- ogy (MIT), Technical University Munich, Transtechno, University of the Bundes- wehr Munich, University of Vermont, Vienna University of Technology, Viterra Energy Services, Weinzierl Engineering. VII Preface to Volume 2 of “Sensors Applications” Sensors in Intelligent Buildings. Edited by O. Gassmann, H. Meixner Copyright © 2001 Wiley-VCH Verlag GmbH ISBNs: 3-527-29557-7 (Hardcover); 3-527-60030-2 (Electronic) The main focus of this book relies on the system principle which is gaining more and more importance throughout the building control industry. Instead of just describing briefly the different types of sensors, it is the aim of the book to il- lustrate which sensors and sensor systems are used in which subsystem, to ex- plain which reasons were decisive for using especially a particular sensor and to give an outline of future developments. In all chapters a description of the system is followed by a discussion of the sensors currently used. This includes a discus- sion of their strengths and weaknesses and especially an illustration of the rea- sons why these sensors made it to industrial building applications. In every area we also provide a short outlook on upcoming sensors and sensor systems – also deduced from the question of what the developments to the subsystem will be and which new sensor types will therefore be needed. This book has been produced with the contributions of many people. We are very grateful to the authors who spent valuable time to share their research results and experiences with the scientific community. Especially we would like to thank Verena Klaassen, who gave us invaluable assistance in preparing this book. Many thanks go also to the publisher and series editors for their fruitful cooperation.
