Auf dem Gebiet der Ventilatoren ist in jiingster Zeit ein unerwarte- ter Aufschwung eingetreten, der auf die Losung verschiedener stro- mungstechnischer Probleme zuriickzufiihren ist. Die Entwicklung war so rasch, daB plotzlich ein Wirkungsgrad von 90% bei kleiner Bauart er- reieht wurde. Infolgedessen gewann die bis dahin stiefmiitterlich be- handelte Maschinengruppe ganz erheblich an Interesse, was auch durch Dbersetzungen des Buches in mehrere fremde Sprachen zum Ausdruek gekommen ist. Es diirfte nunmehr der geeignete Zeitpunkt sein, das Gesamtgebiet in straffer Form neu darzustellen. Ieh habe vieles umgearbeitet, man- ehes Entbehrliche gestrichen und zahlenmaBige Ergebnisse neuer Ver- suche fUr den Praktiker aufgenommen. Bei Kleinstgeblasen und Quer- stromgeblasen sind wesentliche Erweiterungen erfolgt. Die wichtigen physikalischen GesetzmaBigkeiten wurden ausfiihrlicher gebraeht, die bisherigen Berechnungsverfahren ergiinzt. So erga b sieh eine weit- gehende Neubearbeitung. Mein Manuskript wurde von Prof. Dipl.-Ing. habil. M. PECORNIK (V orstand des Lehrstuhles fUr Stromungslehre und hydraulische Ma- sehinen u. Schiffsbaufalmltat in Rijeka, Universitat Zagreb) sehr ein- gehend durehgesehen. Er hat verschiedene Umstellungen vorgenommen und die Bezeichnungen der vielen Abbildungen systematisch nach den neuesten Vorschriften vereinheitlicht. Dariiber hinaus verdanke ich Prof. PECORNIK viele weitere Ratschlage und Erganzungen sowie seine Hilfe bei der Korrektur, die er mit groBer Umsicht durchfiihrte. Das Kapitel Sehallerzeugung und Schalldampfung wurde wieder von den bekannten Fachleuten Oberingenieur REGENSCHEIT und Dipl.- Ing. GoEHLICH nahezu vollig neu bearbeitet, wofUr ieh ihnen besonders danken mochte.

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.

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.

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."

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.

This far-reaching and authoritative two-volume set examines a range of potential solutions for low-energy building design, considering different strategies (energy conservation and renewable energy) and technologies (relating to the building envelope, ventilation, heat delivery, heat production, heat storage, electricity and control).

Daylighting and Integrated Lighting Design provides architects, building designers, and students clear direction for the successful inclusion of daylight and integrated electric light in buildings. It presents design teams with the performance analysis resources, energy saving estimates and user satisfaction results they need in order to make informed decisions regarding daylighting and lighting design.

Written by two well-known experts in the field, the book provides:

• critical geometric and material relationships along with proven design process activities, offered in a quick-reference format, with sufficient context to address the range of associated issues present in any building project
• both the "fundamentals" and "applications" which cover design concepts and practice activities applicable to all integrated lighting projects
• specific directives for how the concepts covered are applied in a range of common design scenarios, including architectural rules-of-thumb, instructions for ensuring visual comfort, and preferred approaches for electric lighting control integration.

In demonstrating these necessary insights to designers, the authors employ an iterative analysis of common "daylighting patterns" and illustrate and annotate both successful and unsuccessful examples via built form and simulation. Part of the PocketArchitecture series, this is the ideal pocketbook for any designer serious about reducing the energy impact of their buildings.

This is a definitive guide to the rebound effect in home heating - the increase in energy service use after a technological intervention aimed at reducing consumption. It sets out what the effect is, how it plays out in the home heating sector, what this implies for energy saving initiatives in this sector, and how it relates to rebound effects in other sectors. The book outlines how the concept of the rebound effect has been developed and the scope of research on it, both generally and particularly in the home heating sector. Within the context of energy and CO2 emissions policy, it summarises the empirical evidence, exploring its causes and the attempts that are being made to mitigate it. Various definitions of the rebound effect are considered, in particular the idea of the effect as an energy-efficiency 'elasticity'. The book shows how this definition can be rigorously applied to thermal retrofits, and to national consumption data, to give logically consistent rebound effect results that can be coherently compared with those of other sectors, and allow policy makers to have more confidence in the predictions about potential energy savings.
