This book provides an up-to-date, accessible, and comprehensive
coverage of human cold stress from principles and theory to
practical application. It defines cold stress and how people
respond to it. It describes how to assess a cold environment to
predict when discomfort, wind-chill, hypothermia, shivering,
frostbite, and other consequences will occur. It also advises on
what to do to prevent unacceptable outcomes, including
determination and selection of clothing to preserve comfort and
health. The book will be of interest to practitioners and students
and anyone involved with fields such as textiles, clothing, and
industrial hygiene.
Our responses to our thermal environment have a considerable effect on our performance and behaviour, not least in the relm of work. There has been considerable scientific investigation of these responses and formal methods have been developed for environmental evaluation and design. In recent years these have been developed to the extent that detailed national and international standards of practice have now become feasible. This new edition of Ken Parson's definitive text brings us back up to date. He covers hot, moderate and cold environments, and defines these in terms of six basic perameters: air temperature, radiate temperature, humidity, air velocity, clothing worn, and the person's activity. There is a focus on the priciples and practice of human response, which encorporates psychology, physiology and environmental physics with applied ergonomics. Water requirements, computer modelling and computer-aided design are brought in, as are current standards. Special populations, such as the aged or disabled and specialist environments such as those found in vehicles are also considered. This remains the standard text for the design of environments for humans to live and work safely, comfortably and effectively, and for the design of materials which help the same people cope with their environments.
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

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.
Thousands of people continue to die from heat. Heat illnesses and
advice for preventing heat casualties at work, during heatwaves,
sport and the effects of global warming are described. A new
perspective on thermoregulation integrates physiological and
psychophysical regulated variables. Heat stress indices, the WBGT
and the SWreq are presented. It is time to understand and routinely
use computer simulations of people in hot conditions. How to
understand how a model can be constructed is also described. This
book provides an accessible, concise and comprehensive coverage
into how people respond to heat and how to predict and avoid heat
causalities. A practical productivity model, and Burn thresholds,
complete the book which begins with up to date knowledge on
measurement of heat stress, heat strain, metabolic rate and the
thermal properties and influences of clothing. Features Provides
methods and regulations through international standards Illustrates
the WBGT and analytical heat stress indices and how to construct a
thermal model Discusses the role of clothing on heat stress and
thermal strain Presents a new model for predicting productivity in
the heat Offers a new method of human thermoregulation Considers
heat illness and prevention during heatwaves and in global warming
Thermal comfort is a desirable state familiar to all people.
Providing inspirational indoor and outdoor environments that
provide thermal comfort, in the context of energy use and climate
change, is a challenge for the 21st century. This book provides an
up-to-date, comprehensive coverage of thermal comfort from
principles and theory to practical application. The book begins
with current knowledge and understanding of thermal comfort and its
application to providing thermal conditions for indoor and outdoor
environments. It integrates and presents new ideas to provide a
comprehensive model of thermal comfort so that we can move on from
the 20th and early 21st century and provide a focus for
developments for future decades. This book will be of interest to
practitioners and students and anyone involved with fields such as
environmental design, physiology, ergonomics, human factors,
industrial hygiene, architecture, health and safety and air
conditioning. * Provides current thermal comfort standards and
regulations * Describes the PMV, PPD, ET* and SET thermal comfort
indices * Discusses adaptive thermal comfort, adaptive opportunity
and explains why we have not moved towards a more dynamic and
interactive approach to providing thermal comfort * Presents a new
model relating thermal discomfort to performance * Shows how to
construct a computer model of thermal comfort * Offers how to
conduct a thermal comfort survey Human Thermal Comfort provides new
ideas for achieving thermal comfort for offices, vehicles, atriums,
and plazas of the future.
