Die Berechnung der technischen Einrichtungen zur Heizung, Luftung und Klimatisierung von Gebauden fuBt, soweit sie wissenschaftlich gesichert ist, auf Erkenntnissen der Warme- ubertragung und der Stromungslehre. In zwei Sonderabschnitten dieses Bandes sind daher die wichtigsten Gesetze beider Fachgebiete, die hier zur Anwendung kommen, zusammenhangend dargestellt. Berechnungsgleichungen werden i. allg. in einer mathematischen Form geboten, die ihre unmittelbare Verwendung in der Praxis gestattet. Das bedeutet, daB in manchen Fallen physi- kalisch komplizierte Vorgange stark vereinfacht betrachtet werden mussen und nur die Haupt- einfluBgroBen Beriicksichtigung finden konnen. Die experimentelle Forschung liefert fur solche Naherungsformeln die notwendigen Erfahrungsbeiwerte, durch die der EinfluB der vernach- lassigten Parameter innerhalb abgegrenzter Anwendungsbereiche der Formeln mit ausreichender Genauigkeit erfaBt wird. Gelingt es dabei, die Zahl der Variablen auf 2 bis 3 zu begrenzen, so lassen sich die Losungen in einfachen Zahlentafeln oder Diagrammen darstellen. Die fUr die Berechnung heiz- und klimatechnischer Anlagen wichtigsten Hilfstafeln sind als gesonderte Arbeitsblatter dem Buch angefUgt. Bei der warmetechnischen Berechnung von Heizanlagen kommt man in der Regel mit der stationaren Betrachtung der Warmeubertragungsvorgange aus. Das gilt auch fur die Bestim- mung des Warmebedarfs von Gebauden im ublichen, nachts unterbrochenen bzw. eingeschrank- ten Heizbetrieb, soweit die periodisch sich andernden Raum- und AuBentemperaturen durch reprasentative Mittelwerte uber 24 Stunden erfaBt werden konnen (quasistationarer Zustand). Die zusatzlichen Warmeleistungen beim Anheizen lassen sich dabei mit Hilfe von Naherungs- rechnungen zumeist genugend genau bestimmen.

Glass and Glazing looks at the conservation of one of the most important building materials, and its use in windows, roofing and walling. It considers the technological evolution of glass and glazing systems, the processes causing deterioration, and the practical application and long-term implications of common conservation materials and methods, as well as of alterations to improve performance.

Mortars, Renders and Plasters provides a broad perspective of contemporary conservation theory and practice not otherwise found in one publication, describing the history, physical properties, and deterioration of these important materials. Methods of assessing condition and evaluating options for treatment and repair are discussed, together with a range of practical conservation techniques and maintenance strategies.

During earthquakes, masonry buildings are the most affected, and consequently, damage to these buildings leads to massive loss of life and property. Masonry buildings comprise probably the greatest share of overall housing stock, and in turn, understanding their performance during earthquakes is a pivotal problem in seismic regions. Masonry Construction in Active Seismic Regions presents details on the kinds of masonry building found in seismic regions of the world. The title describes interventions, such as retrofitted solutions, dynamic identification, and improved construction after earthquakes, that are equally applicable to regions of moderate and high seismicity. The book covers representative masonry buildings from active seismic regions, the material properties of masonry construction, numerical modelling techniques and computational advances, seismic performance of non-engineered masonry buildings, resilience in typical construction, retrofitting, and the cultural values and structural characterization of heritage masonry buildings in active seismic regions. This book is unique in its global and systematic coverage of masonry construction in seismic regions.

A week on a beach, a day at a spa, a hike in the hills -- tourism is taken for granted today, but over the past 500 years, it has played a significant role in the shaping of modern Britain. Holidays were once effectively limited to a handful of wealthy people, but by the 20th century a day at the seaside had become almost universal. In the process quiet villages have becoming busy spa towns, new resorts have been created around Britain's coast and largely unspoilt areas of the countryside have had to cope with the increased mobility of the population. Some places have become wholly reliant on tourism as their primary industry, and with changes in popular tastes in recent years this has created problems for some communities. Tourism and the Changing Face of Britain traces the story of tourism in Britain from the Middle Ages to the present day. It stretches from a time when travel was by horse or coach to the modern era where cheap air travel can take holidaymakers anywhere, including far from Britain's shores. The book shows how holidays, and the pursuit of leisure, have created destinations, sometimes whole towns and even had an impact on the countryside. This wide ranging study examines topics such as pilgrimages, spas, seaside holidays and the discovery of Britain's past, present and future.
