Applied Building Physics: Ambient Conditions, Functional Demands, and Building Part Requirements

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.

Dr. Ir. Hugo S.L.C. Hens is an emeritus professor of the University of Leuven (KULeuven), Belgium. Until 1972, he worked as a structural engineer and site supervisor at a mid-sized architectural office. After the sudden death of his predecessor and promotor Professor A. de Grave in 1975 and after defending his PhD thesis, he stepwise built up the Department of Building Physics at the Department of Civil Engineering.
He taught Building Physics from 1975 to 2003, performance based building design from 1975 to 2005 and building services from 1975 to 1977 and 1990 to 2008. He authored and co-authored 68 peer reviewed journal papers and 174 conference papers about the research done, has helped to manage hundreds of building damage cases and acted as coordinator of the CIB W40 working group on Heat and Mass Transfer in Buildings from 1983 to 1993. Between 1986 and 2008, he was operating agent of the Annexes 14, 24, 32 and 41 of the IEA EXCO on Energy in Buildings and Communities. He is a fellow of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).


Dr. Ir. Hugo S.L.C. Hens ist emeritierter Professor der Universität Leuven (KU Leuven), Belgien. Bis 1972 arbeitete er als Tragwerkplaner und Bauleiter in einem mittelgroßen Architekturbüro. Nach dem plötzlichen Tod seines Vorgängers und Förderers Professor A. de Grave und nach der Verteidigung seiner Doktorarbeit baute er ab 1975 schrittweise das Fachgebiet Bauphysik am Fachbereich Bauingenieurwesen auf. Er lehrte Bauphysik von 1975 bis 2003, Performance Based Building Design von 1975 bis 2005 und Gebäudetechnik von 1975 bis 1977 und von 1990 bis 2008. Hugo Hens war Autor und Mitautor von 68 begutachteten Zeitschriftenaufsätzen und 174 Konferenzbeiträgen über seine Forschungsarbeiten, und erstellte Hunderte von Schadensgutachten und Sanierungsplanungen. Von 1983 bis 1993 wirkte er als Koordinator der CIB W40 Working group für "Heat and Mass Transfer in Buildings". Zwischen 1986 und 2008 war er Beauftragter für die Anhänge 14, 24, 32 und 41 der IEA EXCO on Energy in Buildings and Communities. Er ist Mitglied der American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).
