Résumé

Much of what stands in the preface to the first edition still stands, but advances have been made, especially in PCs and communications, which are reflected in substantial revisions to three chapters and the addition of four completely new chapters. The new CIBSE Guide A was published as this book was being typeset so only brief reference is made to the new notation and modified thermal models in it.

Chapter 13 on network analysis was added as more air and water systems are using variable-speed drives to regulate fans and pumps and the systems contain VAV dampers and two-port valves which can be difficult to design and control. A number of analysis tools and examples are given to aid greater understanding of these systems.

Natural ventilation is increasingly popular, and Chapter 11 deals with its control and the use of night ventilation and building fabric to reduce daytime peak temperatures. There is also a detailed description of wind- and stack driven ventilation and the relevant equations. Case studies are also discussed in detail.

Displacement ventilation, chilled ceilings, chilled beams and mixed-mode air conditioning are discussed in Chapter 12 as well as the control of lighting. As shading and blinds become more essential, the importance of artificial lighting control is stressed. Conventional air-conditioning systems using fan coils and VAV boxes are still very much in use, and Chapter 10 gives an in-depth analysis from. first principles.

Sick building syndrome, however nebulus and difficult to define, haunted building services in the late 1980s and early 1990s. Chapter 1 has been revised to include it in Section 1.6 on occupant feedback. Occupant feedback is a vital part of the commissioning and management process for new and existing buildings. As a profession, we must heed the complaints and sometimes compliments of the occupants regarding the building and its facilities. A questionnaire is discussed that allows a fingerprint and score to be derived for the occupants' satisfaction with the building and its services. Hopefully this will allow a more user-friendly analysis of the questionnaire.

Much of the work is based on my research and lectures since I have been at UMIST. My thanks are therefore to my colleagues, researchers and students who have helped me directly or indirectly to revise and rewrite this book. Especial thanks are due to Ivan Khoo, Steve Fotios, Li Mei, Virginia Cooper and Andy Wright; Don McIntyre for his useful comments on the four new chapters; Jonathan Dewsbury for his comments on the natural ventilation chapter; Tony Sung and Ken Letherman; Eric Keeble for comments related to the weather data; and Peter Tunnel, Peter Day and Malcolm Clapp for practical comments. However, any errors are mine alone.

Finally I would like to thank Carolyn for her help and for bearing with my long periods at the PC. I thank Tom for helping with the figures and Alison for being patient in waiting to use the PC. I also thank my mother.
