As a result of being asked to give public lectures on the subject, the eminent physicist Oliver Lodge (1851 1940) published in 1892 a pioneering study of the protection of buildings, cables and telegraphic instruments from the devastation caused by lightning strikes. This work led him almost immediately to the discovery of electromagnetic wave transmission and ultimately to the development of a version of radio telegraphy. Lodge also saw that many of the current theories about the nature of lightning were seriously in error, and his investigations led to a number of significant changes in the design of lightning conductors and lightning guards. Some of the methods and procedures that Lodge advocated have since become standard practice. They are described with Lodge's characteristic flair and accompanied by a wealth of illustrations that give a fascinating insight into how contemporary scientists and engineers tackled this significant problem.

This book supports HVAC planners in reducing the cooling energy demand, improving the indoor environment and designing more cost-effective building concepts. High performance buildings have shown that it is possible to go clearly beyond the energy requirements of existing legislation and obtaining good thermal comfort. However, there is still a strong uncertainty in day-to-day practice due to the lack of legislative regulations for mixed-mode buildings which are neither only naturally ventilated nor fully air-conditioned, but use a mix of different low-energy cooling techniques. Based on the findings from monitoring campaigns (long-term measurements in combination with field studies on thermal comfort), simulation studies, and a comprehensive review on existing standards and guidelines, this book acts as a commonly accessible knowledge pool for passive and low-energy cooling techniques.

Focuses on the methods of solving incompressible flows, although flows with significant property change due to heat transfer are also covered. Covers turbulent flow simulation, unstructured mesh, and two-phase flows. Uses a practical approach for CFD to build a foundation for those planning to work on low-speed flows. Provides detailed steps of solving 1-D and 2-D flow examples and MATLAB (R) codes of important algorithms. Includes numerous real-word examples and worked problems.

It's a contraption that makes the lists of "Greatest Inventions Ever"; at the same time, it's accused of causing global disaster. It has changed everything from architecture to people's food habits to their voting patterns, to even the way big business washes its windows. It has saved countless lives . . . while causing countless deaths. Most of us are glad it's there. But we don't know how, or when, it got there.
It's air conditioning.
For thousands of years, humankind attempted to do something about the slow torture of hot weather. Everything was tried: water power, slave power, electric power, ice made from steam engines and cold air made from deadly chemicals, "zephyrifers," refrigerated beds, ventilation amateurs and professional air-sniffers. It wasn't until 1902 when an engineer barely out of college developed the "Apparatus for Treating Air" a machine that could actually cool the indoors and everyone assumed it would instantly change the world.
That wasn't the case. There was a time when people "ignored" hot weather while reading each day's list of heat-related deaths, women wore furs in the summertime, heatstroke victims were treated with bloodletting . . . and the notion of a machine to cool the air was considered preposterous, even sinful.
The story of air conditioning is actually two stories: the struggle to perfect a cooling device, and the effort to convince people that they actually needed such a thing. With a cast of characters ranging from Leonardo da Vinci and Richard Nixon to Felix the Cat, Cool showcases the myriad reactions to air conditioning some of them dramatic, many others comical and wonderfully inconsistent as it was developed and presented to the world. Here is a unique perspective on air conditioning's fascinating history: how we rely so completely on it today, and how it might change radically tomorrow.

A number of metrics for assessing human thermal response to climatic conditions have been proposed in scientific literature over the last decades. They aim at describing human thermal perception of the thermal environment to which an individual or a group of people is exposed. More recently, a new type of "discomfort index" has been proposed for describing, in a synthetic way, long-term phenomena. Starting from a systematic review of a number of long-term global discomfort indices, they are then contrasted and compared on a reference case study in order to identify their similarities and differences and strengths and weaknesses. Based on this analysis, a new short-term local discomfort index is proposed for the American Adaptive comfort model. Finally, a new and reliable long-term general discomfort index is presented. It is delivered in three versions and each of them is suitable to be respectively coupled with the Fanger, the European Adaptive and the American Adaptive comfort models.

Air conditioning boosts man's efficiency no less than his comfort. Air-conditioned homes, offices, and factories unmistakably raise human productivity and reduce absenteeism, turnover, mistakes, accidents and grievances, especially in summer. Accordingly, many employers every year cool workrooms and offices to raise summer profits. Employees in turn find cool homes enhancing not only comfort and prestige but also personal efficiency and income. With such economic impetus, low-cost summer cooling must irresistibly spread to all kinds of occupied buildings. Refrigeration provides our best cooling, serving well where people are closely spaced in well-constructed, shaded, and insulated structures. However, its first and operating costs bar it from our hottest commercial, industrial, and residential buildings. Fortunately, evaporative cooling is an economical substitute in many regions. First used in Southwest homes and businesses and in textile mills, it soon invaded other fields and climates. In 1946, six firms produced 200,000 evaporative coolers; in 1958, 25 firms produced 1,250,000, despite the phenomenal sale of refrigerating window air conditioners. Though clearly secondary to refrigeration, evaporative cooling is 60 to 80 percent is economical for moderate income groups and cheaper to buy and operate. Thus, it climates where summers are short. Moreover, it cheaply cools hot, thinly constructed mills, factories, workshops, foundries, powerhouses, farm buildings, canneries, etc., where refrigerated cooling is prohibitively expensive.

When we think of indoor pollution, we usually think of conditions originating from faulty ventilation systems, second hand smoke, and other air borne pollutants. Taking an in-depth, hard science look at the problems of indoor environmental pollution, Indoor Environmental Quality covers all the major indoor contaminants - inorganic, organic, and biological.

Renowned author Thad Godish expands the scope of "indoor air quality" issues to include the entire indoor environment, both in the workplace and the home. He covers:
o hand-to-mouth transfer of lead, pesticides and asbestos
o dermal exposures from pesticide-contaminated dust
o contact with office materials such as carbon paper and other printed papers
o Naturally occurring and man-made contaminants such as radon and asbestos

Godish discusses specific techniques including ventilation and air cleaning that can aid you in the clean-up of indoor air problems. He presents the major issues and concepts, and provides supporting facts in a highly readable style.
An excellent, comprehensive, clear introduction to the issues associated with the quality of the indoor environment, Indoor Environmental Quality gives you the how-tos for controlling contaminants at the source. Its readability makes it ideal for anyone who needs information about specific indoor air problems, and how to diagnose and mitigate them.

During the nineteenth century, Britain became the first gaslit society, with electric lighting arriving in 1878. At the same time, the British government significantly expanded its power to observe and monitor its subjects. How did such enormous changes in the way people saw and were seen affect Victorian culture? To answer that question, Chris Otter mounts an ambitious history of illumination and vision in Britain, drawing on extensive research into everything from the science of perception and lighting technologies to urban design and government administration. He explores how light facilitated such practices as safe transportation and private reading, as well as institutional efforts to collect knowledge. And he contends that, contrary to presumptions that illumination helped create a society controlled by intrusive surveillance, the new radiance often led to greater personal freedom and was integral to the development of modern liberal society.
"The Victorian Eye"'s innovative interdisciplinary approach--and generous illustrations---will captivate a range of readers interested in the history of modern Britain, visual culture, technology, and urbanization.

Solar Technologies for Buildings is an excellent reference for scientists, engineers, planners, researchers and students, involved in developing solar energy systems. Architects integrating solar technologies in building design will find this application-orientated approach useful.

The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice. Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favours an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.

Over the past 20 years, energy conservation imperatives, the use of computer based design aids, and major advances in intelligent management systems for buildings have transformed the design and operation of comfort systems for buildings. The "rules of thumb" used by designers in the1970s are no longer viable. Today, building systems engineers must have a strong analytical basis for design synthesis processes. But how can you develop this basis? Do you have on your shelf a reference that describes all the latest methods? Does it cover everything from the fundamentals to state-of-the art, intelligent systems? Does it do so in practical way that you can easily access and use when you need to? The Handbook of Heating, Ventilation, and Air Conditioning does. It combines practice and theory, systems and control, and the latest methods and technologies to provide, in one volume, all of the modern design and operation information needed by HVAC engineers. The Handbook of Heating, Ventilation, and Air Conditioning will stay up-to-date while other resources become outmoded and go through lengthy revision and reprint processes. Through a link on the CRC Web site, owners of the Handbook can access new material periodically posted by the author.

The second edition of this reliable text provides readers with a thorough understanding of the design procedures that are essential in designing new buildings and building refurbishment.

New additions include:

• extended and updated worked examples
• two new appendices covering renewable energy systems and sustainable building engineering - with startling conclusions.

This book is an invaluable guide for HND and degree level students of building services engineering, as well as building, built environment, building engineering and architecture courses.

This book addresses smoke management in enclosures and provides a platform for understanding the principles of smoke propagation and spread, heat release rate, and the effect of sprinklers on suppression. Considering how sprinkler systems have become a vital part of firefighting systems in enclosures, the book evaluates the effect of sprinkler activation on the behavior of fire-induced smoke and the interaction of water particles with the smoke layer. It studies two base case models where the sprinklers' effect on the fire curve was considered. This base case was assessed with two smoke extraction systems, namely, a ducted system and an impulse ventilation system. By focusing on key elements, such as visibility, ceiling height, and fire curve, the results of the study will be of interest to mechanical engineers, HVAC professionals, and fire safety professionals and investigators.
