Description

In the ten years since the publication of the second edition of Human Thermal Environments: The Effects of Hot, Moderate, and Cold Environments on Human Health, Comfort, and Performance, Third Edition, the world has embraced electronic communications, making international collaboration almost instantaneous and global. However, there is still a need for a compilation of up-to-date information and best practices. Reflecting current changes in theory and applications, this third edition of a bestseller continues to be the standard text for the design of environments for humans to live and work safely, comfortably, and effectively, and for the design of materials that help people cope with their environments.

See What’s New in the Third Edition:

  • All existing chapters significantly updated
  • Five new chapters
  • Testing and development of clothing
  • Adaptive models
  • Thermal comfort for special populations
  • Thermal comfort for special environments
  • Extreme environments
  • Weather
  • Outdoor environments and climate change
  • Fun runs, cold snaps, and heat waves

The book covers hot, moderate, and cold environments, and defines them in terms of six basic parameters: air temperature, radiant temperature, humidity, air velocity, clothing worn, and the person’s activity. It focuses on the principles and practice of human response, which incorporates psychology, physiology, and environmental physics with applied ergonomics. The text then discusses water requirements, computer modeling, computer-aided design, and current standards. A systematic treatment of thermal environments and how they affect humans in real-world applications, the book links the health and engineering aspects of the built environment. It provides you with updated tools, techniques, and methods for the design of products and environments that achieve thermal comfort.

Reviews

"… a solid review of a very important topic … a key source of information for research students and others new to the field …"

—Tord Kjellstrom, Professor of Environmental and Occupational Health, Retired, Umea University, Sweden, Australian National University and University College London

"… the most comprehensive book available on the effects of human thermal environment on human responses and the methods for analyzing the environment, human, and clothing. … readable because of its logical structure and serviceable size."

—Hannu Rintamäki, Finnish Institute of Occupational Health

"… a tour de force … Professor Parsons carefully walks the reader through the fundamental principles, followed by the integration into models, to assessment strategies, and wraps it up with higher level discussion of complex exposures and emerging concerns. His commentary along the way is very informative."

—Thomas E. Bernard
