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 energy efficiency, decarbonization and sustainability ? all these have accelerated the development of a discipline 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, energy efficiency, and, in some countries, fire safety. Through the application of physical knowledge and its combination with information coming from other disciplines, building physics helps to under-stand the physical phenomena governing building parts, building envelope, whole building and built environment performance ? called urban physics. Today, building physics has be-come a key player on the road to highly performing new buildings and renovations.This book deals with heat, air and moisture transport in building parts or assemblies and whole buildings with emphasis on the building engineering applications.Compared to the third edition, this fourth edition has been expanded in chapter 1 to include the physical determination of the thermal conductivity of materials, together with an in-depth discussion of all the effects of thicker insulation layers. In chapter 2, additional information has been added on wind pressure and the evaluation of condensation inside the building com-ponents, while a new chapter 4 on material properties has been included. The whole book, including the figures, has been revised and restructured where necessary.

While the first volume on building physics deals with the physical principles of heat, air and moisture behaviour of buildings, building structures and components, this second volume on applied building physics focuses on the question of what the desired performance of buildings consists of. To achieve this, knowledge of the external environmental effects and the internal live loads to which buildings are subjected is a necessary first step. Subsequently, the performance requirements and the physical correspondences are deepened with the determination of their physical parameters, at the levels of buildings, building structures and building components.Compared to the second edition, the discussion of criteria is not limited to thermal comfort, but also includes acoustic, visual and olfactory aspects. Likewise, the indoor air quality is considered in a broader way. Analyses and calculations result in sustainable buildings with a comfortable indoor climate from functional and durable building constructions.Compared to the second edition, the text for the third edition has been reorganised, corrected, revised and expanded where appropriate. A useful appendix for quick reference contains standard values of material properties for a wide range of building materials.The analyses and calculations described in this book result in sustainable buildings made of functional and durable building constructions, with comfortable and healthy indoor climate and air quality.Compared to the second edition the text in this third edition has been reshuffled, corrected, reworked and extended where appropriate.

Here, the environmental loads on buildings are explained - i.e. all those parameters that describe the external and internal environmental conditions, with an emphasis on practical implementation. Then follows a comprehensive presentation of those performance requirements that are important at the whole-building level, mainly considering thermal, acoustic, visual and olfactory comfort, indoor air quality, energy consumption, durability, economy and sustainability. This is followed by an in-depth discussion of the requirements regarding thermal, air and moisture behaviour as well as the measured variables at the level of the building construction and components. The analyses and calculations described in this book result in sustainable buildings made of functional and durable building constructions, with comfortable and healthy indoor climate.Compared to the previous editions, both books have been expanded to include the physical determination of the thermal conductivity of materials, together with an in-depth discussion of all the effects of thicker insulation layers. Additional information has been added on wind pressure and the evaluation of condensation inside the building components, while a new chapter on material properties has been included.Both volumes, including the figures, have been revised and restructured where necessary.

Performance-Based Building Design This third book in a series of three dealing with building physics and its application, looks to the impact a performance requirements linked approach has on building design and construction. It starts with a resumption of what’s expected from buildings, followed by discussing a range of materials needed to guarantee a correct heat, air, moisture response. Then, looked is to preparing the building site, the excavations needed, the foundations, the below-grade parts and spaces, the structural systems commonly used, the floors, different types of outer walls, different types of roof assemblies, inside walls, the glazing, windows, outer doors, glass façades, bal-conies, all kind of shafts, chimneys, stairs, timber-frame construction, wall, floor and ceiling finishes. Each time again, not only the heat, air, moisture related metrics but also structural integrity, durability, fire safety, acoustics, maintenance, sustainability and buildability are dis- cussed. The whole ends with looking to the risks deficiencies may cause. For this new edition, all chapters have been critically reviewed, actualized and gifted with additional figures where needed, so incorporating the experiences gained from 38 years of teaching to architectural and building engineering students, from 36 years of research, and from 53 years of practice, curing damage cases due to failing performance.
