Book Synopsis Energy and Thermal Time Constant in Buildings by : Joseph Nowarski
Download or read book Energy and Thermal Time Constant in Buildings written by Joseph Nowarski and published by Joseph Nowarski. This book was released on 2016-05-02 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of building's exterior walls has important influence on energy consumption, building cost and thermal comfort. It influences also heating and cooling devices size. Optimization of energy consumption of the building requires consideration of the building materials, their thickness and mass, type and thickness of insulation, and location of the insulation layer. The correct way to optimize all the above parameters is calculation of temperatures and energy consumption in dynamic process, which means considering changes every few seconds. This may be done only with computer program. It is not easy to gain expertise on such programs. In addition, submission of input values to the program is time consuming and frustrating process, which in many times ends with errors. This work analyses if the Thermal Time Constant method may be applied to determine energy quality of the building as an alternative to the dynamic simulation program. The Thermal Time Constant method is much easier, simpler and faster than computer dynamic simulation program. Few examples of exterior wall design were selected to calculate the energy consumption and room temperatures. Two locations were selected for the calculations, one with moderate summer and the second with moderate winter. The dedicated dynamic simulation computer program was applied to gain data regarding the energy consumption, maximum and average room temperatures for south facing room and for north facing room at each location. Thermal Time Constant reflects the thermal inertia and thermal mass of the building. Higher Thermal Time Constant (TTC) moderates the difference between day and night in the room, flattening the room temperatures extremes caused by ambient temperature and solar energy. Higher TTC is not necessary more expensive. To take advantage of high TTC is not so the question of additional investment, but the question of understanding the TTC concept. In some cases consideration of TTC caused changes to the building's design and construction technique, bringing benefits to the contractor, to the tenants and to the national economy. Disregarding TTC leads to wrong decisions, wrong design, waste of money for building's construction and increased energy consumption.

Book Synopsis Number of Thermal Time Constants - nTTC by : Joseph Nowarski
Download or read book Number of Thermal Time Constants - nTTC written by Joseph Nowarski and published by Joseph Nowarski. This book was released on 2017-03-19 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal Time Constant (TTC) indicates the time required for change of 63.2% of temperature difference. This work develops useful application of TTC for determination of temperature change in buildings. Higher TTC results in slower change of room temperature, contributing to thermal comfort, to quality of the building and to energy conservation. The procedure developed in the work is for both purposes: to find the temperature change in the period of time and to find the period of time of specific temperature change.

Available in PDF, EPUB and Kindle. Book excerpt: The design of a building's exterior walls has an important influence on energy consumption, building cost and thermal comfort. It influences also heating and cooling devices’ size. Optimization of energy consumption of the building requires consideration of the building materials, their thickness and mass, type and thickness of insulation, and location of the insulation layer. The correct way to optimize all the above parameters is a calculation of temperatures and energy consumption in a dynamic process, which means considering changes every few seconds. This may be done only with a computer program. It is not easy to gain expertise in such programs. In addition, submission of input values to the program is time consuming and frustrating process, which many times ends with errors. This work introduces the term “Thermal Time Constant” which may be applied to determine the thermal quality of the building as an alternative to the dynamic simulation program. The Thermal Time Constant method is much easier, simpler and faster than a computer dynamic simulation program. Higher Thermal Time Constant (TTC) moderates the difference between day and night in the room, flattening the room temperature extremes caused by ambient temperature and solar energy.

Book Synopsis Applied Building Physics by : Hugo S. L. Hens
Download or read book Applied Building Physics written by Hugo S. L. Hens and published by John Wiley & Sons. This book was released on 2012-01-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Desert Development by : Yehuda Gradus
Download or read book Desert Development written by Yehuda Gradus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fact that approximately one-third of the world's land mass is arid desert may be congenial for the camel and the cactus, but not for people. Nevertheless, well over half a billion people, or 15% of the world's population live in arid desert areas. If the world's population were distributed evenly over the land surface, we would expect to find about 30% of the population inhabiting arid desert areas. Does the fact that 'only' 15% of the world's population live in an arid desert environment reflect the harshness of the environment? Or is it a testimony to the adaptability and ingenuity of mankind? Do we view the glass as half-full? Or half-empty? The contributors to Desert Development: Man and Technology in Sparselands adopt the position that the cup is half-full and, in fact, could be filled much more. Indeed, many arid desert zones do thrive with life, and given appropriate technological develop ment, such areas could support even greater popUlations. While the dire Malthusian prediction that rapid world population growth exceeds the carrying capacity of existent resource systems has gained popularity (typified by the 1972 Club of Rome book, Limits to Growth), there is a growing body of serious work which rejects such pessimistic 'depletion' models, in favor of models which are mildly optimistic.
Book Synopsis Research in Building Physics and Building Engineering by : Paul Fazio
Download or read book Research in Building Physics and Building Engineering written by Paul Fazio and published by CRC Press. This book was released on 2020-11-26 with total page 1017 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
