Klappentext
COVERS THE TRADITIONAL AND THE MOST UP-TO-DATE DESIGN PRACTICES OF ENGINEERING BUILDING SERVICES

Building Services Engineering offers a comprehensive guide to the design practices of existing engineering building services and explains how the traditional methods integrate with the more recent, smarter developments in the field. In this text, the authors explore current technologies and some of the newest advances including: smart ventilation, smart glazing systems, smart batteries, smart lighting, smart soundproofing, smart sensors and meters, designed to contribute to a healthier lifestyle for occupants of the indoor environment. This book fills the need for a resource in the field of smart, sustainable building services design. Containing over 100 fully worked examples and tutorial questions, it highlights sustainable alternatives in order to encourage the creation of healthier environments. This text: Provides the theory and analysis of existing engineering building services Examines the problems of providing an acceptable indoor environment from engineering, energy and anthropocentric perspectives Provides the reader with considerable scope for testing their learning Meets the need for a text suitable for a transitional stage in the evolution of buildings Building Services Engineering is an ideal text for courses on mechanical engineering and building services engineering. It also provides a valuable insight for those studying other related disciplines in the construction and facilities management sector.
