For Technician level courses in electrical and mechanical systems found in departments of construction and civil technology. This text provides an in-depth view of the mechanical and electrical systems in construction, followed by a step-by-step approach to the design of each system. Intended to provide an introduction to building mechanical and electrical design concepts and principles, this major revision of a classic text is written for all those involved in the construction industry. Elementary engineering concepts and design principles are introduced in a straightforward manner and presented on an elementary mathematics level; requiring students to have a working knowledge of algebra. This book addresses the growing complexity of design standards and regulations and rapid changes in new building technologies, which in turn is expanding the role of the architectural and engineering technician. NEW-Fourteen chapters have been totally rewritten. The remaining chapters have been updated and expanded.~Provides new information to reflect changes in the industry. NEW-Content has been added on piping, pumps, on-site sewage systems, occupant comfort, indoor air quality, psychrometrics, solar energy, telecommunications, and energy efficiency.~Provides students with up-to-date industry information. NEW-Over 120 detailed figures and dozens of tables on building mechanical and electrical equipment.~Improves understanding of material by creating a visual connection for readers. NEW-Over 300 photographs have been added or updated.~Helps to improve the reader's understanding. NEW-Homework exercises and design problems.~Provided to introduce basic principles with real-world connections. Content on applicable codes, reference book design and design procedures-Such as National Standard Plumbing Code, National Electrical Code, Fundamentals Handbook, ASHRAE, and Illumination Society of America.~Keeps students informed of current codes and standards. Continuing design problems throughout-An apartment building for the plumbing system, and a residence for the heating, air conditioning and electrical systems.~Presents students with challenging problems to work through. Conveniently locates all charts and tables at the end of each chapter.~Encourages review of material by making references easily accessible.
