Indoor climate is determined by rational lighting, heating, cooling and ventilating systems. For occupants' well-being it should be consistent with how regional outdoor climate works in the flow of radiation via four paths of heat transfer: radiation; convection; conduction; and evaporation. This book starts with the relationship between the human body and its immediate environmental space followed by a brief introduction of passive and active systems for indoor climate conditioning. The nature of light and heat is discussed with a focus on building envelope systems such as walls and windows, and then examined from the viewpoint of thermodynamics and human-biology. Some examples are given to enable a better understanding of luminous and thermal characteristics of our most immediate environment particularly for those professionally involved in environmental planning, designing, and engineering to know about bio-climatic design principle.

Die dritte Auflage des Klassikers Stahlbetonbrucken behandelt in umfassender Form die Grundlagen des konzeptionellen Entwurfs sowie der Projektierung, Ausfuhrung und Erhaltung von Brucken aus Stahl- und Spannbeton. Diese Grundlagen sind entscheidend fur die Asthetik, Tragsicherheit, Dauerhaftigkeit und Wirtschaftlichkeit einer Brucke. Mit einfachen Modellen wird ein Hochstmass an Klarheit und Verstandlichkeit erreicht. Auf Detailberechnungen wird verzichtet, da sie meist von sekundarer Bedeutung sind und weder auf die Qualitat noch auf die Wirtschaftlichkeit einer Brucke einen nennenswerten Einfluss haben. Fur Qualitat und Dauerhaftigkeit von Stahlbetonkonstruktionen spielen die Anordnung der Bewehrung und die konstruktive Ausbildung eine entscheidende Rolle, weshalb grundsatzliche Losungsmoglichkeiten dargestellt werden. Die Themen Entwurf, Baustoffe, Einwirkungen, Ausrustungsteile, Schragkabelbrucken und Erhaltung wurden grundlegend uberarbeitet und erweitert."

Combustion is very much an interdisciplinary topic, drawing together elements of chemistry, fluid mechanics and heat transfer. It is an ingredient in many undergraduate degree programmes, ranging from a pivotal role in fuel science through to a component part of courses in chemical, process and building services engineering. For many students in those disciplines where combustion in heating plant is an important part of their studies, there are often problems in coming to grips with the basic principles underlying the combustion of hydrocarbon fuels. In particular, the concepts of chemical and related thermodynamic changes can prove difficult to assimilate. The scientific literature dealing with combustion tends to be rather polarised, with a wealth of literature aimed at the specialist reader, but at a basic level the fundamentals of this important process are often treated rather tersely in textbooks on thermodynamics. The objective of this book is to provide an introduction to the basic principles of the combustion of hydrocarbon fuels in heating plant for buildings and industrial processes. In those chapters where practice in problem solving can make a positive contribution to understanding, some numerical problems have been included. Acknowledging the ever-widening use of computers in technical education, a number of algorithms which can be easily coded up for solving numerical problems have been incorporated in the text. These can prove particularly useful in, for example, the calculation of certain fluid properties, either for use in hand calculation or for incorporation into larger programs.

Energy efficiency in buildings requires, among other things, that ventilation be appropriately dimensioned: too much ventilation wastes energy, and insufficient ventilation leads to poor indoor air quality and low comfort. Studies have shown that ventilation systems seldom function according to their commissioned design. They have also shown that airflow measurement results are essential in improving a ventilation system. This key handbook explains why ventilation in buildings should be measured and describes how to measure it, giving applied examples for each measurement method. The book will help building physicists and ventilation engineers to properly commission ventilation systems and appropriately diagnose ventilation problems throughout the life of a building. Drawing on over 20 years of experience and the results of recent international research projects, this is the definitive guide to diagnosing airflow patterns within buildings.

Ein wichtiger Bereich fur das Ziel eines nachhaltig zukunftsfahigen Wirtschaftens im Bedurfnisfeld "Bauen und Wohnen" ist der bisher in der Forschung wenig berucksichtigte Bereich der Altbaumodernisierung. Hierin liegen sehr grosse Potentiale, aber auch Hemmnisse fur Massnahmen zur Energieeinsparung. Ausserdem fallen bei Neueinbau und Entsorgung erhebliche Mengen von Stoffstromen in vielfaltiger Zusammensetzung und zum Teil mit problematischen Inhaltsstoffen an. Die Studie untersuchte die komplexen Strukturen, Rahmenbedingungen, Entscheidungsprozesse, Verflechtungen der beteiligten Akteure und Hemmnisse fur ein zielfuhrendes Stoffstrommanagement bei der Altbaumodernisierung an Fallbeispielen sowie mittels zahlreicher Gesprache mit Beteiligten im Baugeschehen und eines Workshops mit Akteuren aus dem Bereich des Mietwohnbaus. Daraus wurden Empfehlungen abgeleitet."

This research book aims to conceptualise the scale and spectrum of Building Information Modelling (BIM) and Artificial Intelligence (AI) approaches in energy efficient building design and to develop its functional solutions with a focus on four crucial aspects of building envelop, building layout, occupant behaviour and heating, ventilation and air-conditioning (HVAC) systems. Drawn from theoretical development on the sustainability, informatics and optimisation paradigms in built environment, the energy efficient building design will be marked through the power of data and BIM-intelligent agents during the design phase. It will be further developed via smart derivatives to reach a harmony in the systematic integration of energy efficient building design solutions, a gap that is missed in the extant literature and that this book aims to fill. This approach will inform a vision for future and provide a framework to shape and respond to our built environment and how it transforms the way we design and build. By considering the balance of BIM, AI and energy efficient outcomes, the future development of buildings will be regenerated in a direction that is sustainable in the long run. This book is essential reading for those in the AEC industry as well as computer scientists.

With so many new lighting technologies available for a wide range of visual environments, how do you choose the options that best address the needs and improve the quality of life for various groups? Focusing on applications and everyday use of light sources, The Right Light: Matching Technologies to Needs and Applications provides a comprehensive explanation of all light sources to be used as a guide to choosing the right lighting technology. The book supplies a quick overview of the main characteristics of the existing technologies in the market and suggestions for appropriate technologies for a range of applications from health related issues to safety and security. The author characterizes different lamp technologies based on the large number of parameters required when choosing a light source. He makes suggestions based mainly on the qualities of the light such as color/wavelength of the light, color rendering index of the source, and, in the case of white light, the color temperature. Other parameters such as the luminous flux or the lifetime may play a role in some cases. From the improvement of the quality of life of people in their working and living spaces, to road safety or treatment of medical conditions and from managing cancer rates to improving the lives of vision impaired people, the correct choice of light sources and the appropriate lighting design can indeed make the difference between comfortable and problematic everyday life or indeed life and death.

Lighting has the power to illuminate and enhance our experience within the built environment. The light that enables people to travel around their neighbourhood or their city; the light which they see themselves and their neighbourhood under. Research into the effects of urban lighting on behaviour, environmental psychology and social interaction is developing at a rapid rate. Yet, despite the affect it has on our daily lives, the practical application of this research is a relatively untapped resource. There has been a persistent trend to use lighting as a tool for urban regeneration and many major urban lighting projects around the country are underway but there is more that can be done on a variety of scales. This book explores the needs and experiences of people at night and how these can be addressed by public lighting. It will give readers the confidence to develop more sophisticated lighting plans and add value to their projects. Case studies provide in-depth analysis of real-life projects and will help the reader to understand lighting designers' own experiences, including post-installation observations. Written in an accessible style by an array of experts, this is an essential book for practitioners, academics and students alike, that will enable you to put the research in to practice and develop better lighting for better places.

The refurbishment of existing buildings is a crucial yet often neglected subject within sustainable architecture; attention is usually focused on new buildings. Many old buildings waste large amounts of energy and provide poor internal conditions for occupants through poor lighting, poor ventilation, solar penetration and glare, and poor control of heating and cooling. Demolition is an option but the refurbishment alternative is increasingly seen as more sustainable in terms of architectural value, materials use, neighbourhood disruption and waste disposal. In addition, the potential impact of low energy refurbishment is much greater than that for new build since there are many more buildings already in existence than will be built in the next 10 - 20 years, the period over which many CO2 emission targets apply. The Handbook of Sustainable Refurbishment: Non-Domestic Buildings offers architects, engineers and a wide range of building professionals practical advice, illustrated by real examples. It moves from principles of sustainable refurbishment to specific design and engineering guidance for a variety of circumstances. It emphasises the need for an integrated approach by showing how refurbishment measures interact with one another and with the occupants, and how performance is ultimately influenced by this interaction.
