Fostering the energy efficiency and the energy independence of the building sector is a focal aim to move towards a decarbonized society. In this context, building physics and building energy systems are fundamental disciplines based on applied physics applications in civil, architectural, and environmental engineering, including technical themes related to the planning of energy and the environment, diagnostic methods, and mitigating techniques. This Special Issue contains information on experimental studies in the following research topics: renewable energy sources, building energy analysis, rational use of energy, heat transmission, heating and cooling systems, thermofluid dynamics, smart energy systems, and energy service management in buildings.




Building Physics - Heat, Air and Moisture


Book Description

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.

Applied Building Physics


Book Description

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.




Research in Building Physics and Building Engineering


Book Description

Buildings influence people. They account for one third of energy consumption across the globe and represent an annual capital expenditure of 7%-10% of GNP in industrialized countries. Their lifetime operation costs can exceed capital investment. Building Engineering aims to make buildings more efficient, safe and economical. One branch of this discipline, Building Physics/Science, has gained prominence, with a heightened awareness of such phenomena as sick buildings, the energy crisis and sustainability, and considering the performance of buildings in terms of climatic loads and indoor conditions. The book reflects the advanced level and high quality of research which Building Engineering, and Building Physics/Science in particular, have reached at the beginning of the twenty-first century. It will be a valuable resource to: engineers, architects, building scientists, consultants on the building envelope, researchers and graduate students.




Building Physics: Lighting


Book Description

Building Physics: Lighting, Seeing in the Artificial Environment deals with basic principles of lighting as used in architecture, in building maintenance, and in an artificial environment. The book starts with the process of how humans see; the interaction of the eye and mind; and the effects of fatigue, visual disorders, and age. The phenomena of light are then discussed — how light behaves and how it is measured. Light and light waves beyond the visible spectrum are explained scientifically as being part of the electromagnetic spectrum within the 400 to 760 nm ranges. The different light sources are identified as daylight and artificial lights, with many types of lamps under the latter. As regards artificial lighting, a lighting fitting has two functions: redistributes luminescence properly and provides a suitable receptacle for the lamp. The requirements when using artificial or natural light in an exterior or interior setting are enumerated. The book also explains the specifications of the amount of light and how this amount is calculated. Interior lighting, both from artificial and natural sources, is comprehensively discussed, including issues such as discomfort glare, reflected glare, design and aesthetics, lighting requirements in different kinds of buildings, and flammability properties. The text also tackles exterior lighting including decorative floodlights, lighting for tunnels and underpasses, and special problem areas. Architects, engineers, electricians, interior designers, lighting technicians, environmentalists, and readers with interest in home decor will find this book useful.
