Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about "sick buildings", thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards more sustainability - all these have accelerated the development of a field that, for a long time, was hardly more than an academic exercise: building physics (in English speaking countries sometimes referred to as building science). The discipline embraces domains such as heat and mass transfer, building acoustics, lighting, indoor environmental quality and energy efficiency. In some countries, fire safety is also included. Through the application of physical knowledge and its combination with information coming from other disciplines, the field helps to understand the physical phenomena governing building parts, building envelope, whole buildings and built environment performance, although for the last the wording "urban physics" is used. Today, building physics has become a key player on the road to a performance based building design. The book deals with the description, analysis and modeling of heat, air and moisture transport in building assemblies and whole buildings with main emphasis on the building engineering applications, including examples. The physical transport processes determine the performance of the building envelope and may influence the serviceability of the structure and the whole building. Compared to the second edition, in this third edition the text has partially been revised and extended.

Note: New editions of this book have been published: the 2nd edition in 2012, the 3rd edition in 2017, and the 4th edition in September 2023. Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about 'sick buildings', thermal, acoustical, visual and olfactory discomfort, the move towards more sustainability, have all accelerated the development of a field, which until 35 years ago was hardly more than an academic exercise: building physics. Through the application of existing physical knowledge and the combination with information coming from other disciplines, the field helps to understand the physical performance of building parts, buildings and the built environment, and translates it into correct design and construction. This book is the result of thirty years teaching, research and consultancy activity of the author. The book discusses the theory behind the heat and mass transport in and through building components. Steady and non steady state heat conduction, heat convection and thermal radiation are discussed in depth, followed by typical building-related thermal concepts such as reference temperatures, surface film coefficients, the thermal transmissivity, the solar transmissivity, thermal bridging and the periodic thermal properties. Water vapour and water vapour flow and moisture flow in and through building materials and building components is analyzed in depth, mixed up with several engineering concepts which allow a first order analysis of phenomena such as the vapour balance, the mold, mildew and dust mites risk, surface condensation, sorption, capillary suction, rain absorption and drying. In a last section, heat and mass transfer are combined into one overall model staying closest to the real hygrothermal response of building components, as observed in field experiments. The book combines the theory of heat and mass transfer with typical building engineering applications. The line from theory to application is dressed in a correct and clear way. In the theory, oversimplification is avoided. This book is the result of thirty years teaching, research and consultancy activity of the author.

Bad experiences with construction quality, the energy crises of 1973 and 1979,complaints about `sick buildings?, thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards more sustainability ? all these have accelerated the development of a field that, for a long time, was hardly more than an academic exercise: building physics. The discipline embraces domains such as heat and mass transfer, building acoustics, lighting, indoor environmental quality and energy efficiency. In some countries, fire safety is also included. Through the application of physical knowledge and its combination with information coming from other disciplines, the field helps to understand the physical phenomena governing building parts, building envelope, whole building and built environment performance, although for the last the wording `urban physics? is used. Building physics has a real impact on performance-based building design. This volume on `Applied Building Physics? discusses the heat, air and moisture performance metrics that affect building design, construction and retrofitting.

Die Energiekrise der 1970er Jahre, häufig auftretende Feuchteprobleme, Klagen über das Sick-Building-Syndrom und mangelnden Komfort hinsichtlich Raumklima und Behaglichkeit und nicht zuletzt das Bemühen um Nachhaltigkeit haben die Bauphysik zu einem Innovationsmotor auf dem Gebäudesektor gemacht. Dabei war die gesellschaftliche Forderung nach Energieeinsparung in Gebäuden ohne Gebrauchseinschränkungen der Auslöser für die ganzheitliche Planung. Wie alle Ingenieurwissenschaften ist auch die Bauphysik anwendungsorientiert, weshalb sich nach einem ersten Buch über die Grundlagen das vorliegende zweite Buch mit den Hintergründen der Gebrauchstauglichkeit und den Anforderungen an Energieeffizienz in Gebäuden befasst. Außenklimabedingungen und Raumklimaberechnungen werden diskutiert, Energieverluste und -gewinne werden für Gebäude und separat für die Gebäudehülle untersucht. Die wichtigen physikalischen Eigenschaften für den gekoppelten Wärme- und Feuchtetransport durch Baukonstruktionen werden für zahlreiche Materialien aufgeführt. Für das Buch stützt sich der Autor auf seine Erfahrungen aus 35 Jahren Lehre der Bauphysik für Architekten und Bauingenieure und 40 Jahre Tätigkeit in der Forschung und als Beratender Ingenieur.

In the climate-controlled buildings of today, moisture problemsaffect not only the useable life expectancy of the structure, butthe comfort and health of the occupants. This reference is thefirst to apply up-to-date moisture control and treatment techniquesin a problem/solution format. Opening with an introductoryexplanation of the nature and causes of mold, mildew, andcondensation, the book gives specific advice on heated, cooled, andcombination environments, plus a short course in the dynamics ofmoisture movement within buildings. Other invaluable coverageincludes: * clear, detailed recommended practices for all United Statesclimates * practices for cooling as well as heating climates (often, heatingclimate solutions are applied in cooling climates, where problemsand solutions are completely different) * an overall, systematic view of moisture problems--including howmechanical systems and occupant lifestyles can create and alsoresolve moisture problems * actual case studies of buildings with moisture problems thatillustrate the principles and practices presented in the book This detailed, no-nonsense exploration of moisture cause andeffect--as well as its protection and remediation--will expandreaders' knowledge on this crucial subject. Moisture ControlHandbook will be welcomed by building contractors, architects,mechanical engineers, building science researchers, buildingproduct manufacturers, homeowners, and small commercial buildingowners.

An understanding of building physics is fundamental for the design and construction of safe, functional, energy efficient buildings. Without it, occupants’ health and comfort is compromised, energy bills become unmanageable, or the building fabric itself can fail. But it’s not just about providing a heating source or stopping the cold coming in; at the heart of building physics is a fine balancing act: how much ventilation will be required for the occupants and how can that be provided without compromising the thermal performance? How will the layout and fenestration affect light levels and cooling demand? How Buildings Work provides construction professionals with a clear understanding of the basic mechanisms of physics and how they affect the performance and operation of buildings. Heat, air, moisture, sound, light and radioactivity are explained in turn, yet all the while reminding the reader that none of these phenomena can be considered in isolation when designing a building. Whether you’re a student trying to get your head round the basics, or a seasoned practitioner looking for a quick refresher course.
