Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive theoretical platform for the use and construction of double skin façade projects. The DSF concept has been used mostly in European buildings; however, its success in other climates should be addressed. Increasing numbers of buildings are featuring double skin façade technology in the US; however, still relatively few have been studied for their performance in operation. This book gives architects a practical guide to analyze and evaluate the actual performance of double skin façade buildings in different climatic contexts. It is important for high-performance buildings to have tools to evaluate a design’s predicted performance to achieve specific sustainable goals. To determine that the application of DSF in different climates will provide better thermal comfort, building simulation tools analyze various thermal comfort parameters through studies of the façade and compare them with the actual building’s performance data. The book takes the reader on an on-site tour of eight DSF buildings around the US. Interviews with the buildings’ architects and engineers, owners, and users offer additional perspectives and insights into the construction and performance of these developments in building design. This will provide architects with a comprehensive understanding of the challenges and opportunities in integrating double skin façades into their projects.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objectives of this research are (a) to investigate the thermal effect of double skin façades in office buildings in hot climates and (b) to propose guidelines for their efficient design based on this evaluation. The study involves the energy performance analysis of two buildings in India. A base case with the existing building skin was simulated for both the cities. The main source for the high cooling loads was found to be heat gain through windows and walls. This led to the evolution of a series of facade strategies with the goals of reducing heat gain, providing ventilation and day-lighting. The buildings were then simulated for their energy performance with the proposed double-skin strategies. Each of these strategies was varied according to the layers constituting the facade, the transparency of the façade and the orientation of the façade to which it is applied. Final comparisons of energy consumption were made between the proposed options and the base case to find the most efficient strategy and also the factors that affected this efficiency. The simulations were done using the building simulation software, Ener-Win. The double skin was simulated as per an approximate and simplistic calculation of the u-value, solar heat gain coefficient and transmissivity properties of the layers constituting the façade. The model relied on logically arrived at assumptions about the façade properties that were approximately within 10% range of measured values. Based on inferences drawn from these simulations, a set of design guidelines comprised of goals and parameters was generated for design of double-skin façades in hot climates typical to most of the Indian subcontinent. It was realized that the double-skin defined typically as a 'pair of glass skins separated by an air corridor' may not be an entirely energy efficient design strategy for hot climates. However, when used appropriately in combination with other materials, in the right orientation and with the right transparency, a double-layered façade turns out to be an energy efficient solution.

Available in PDF, EPUB and Kindle. Book excerpt: Visually enriched with over 250 photographs and drawings, Bioclimatic Double-Skin Façades is an essential reference guide for understanding the types and functions of double-skin façades. Author Mary Ben Bonham examines the history and continuing potential of double-skin architecture, informing on the variety of approaches possible and advising a rigorous integrated design process leading to application. Featuring a wide selection of architectural examples, the book will be of interest to professionals and students within the fields of architecture, engineering, and construction. Characterized by a buffer-like air space between two glazed building skins, double-skin windows and façades aim to improve building comfort and energy performance. Double skins introduce complexity and initial costs, yet significant buildings in locations around the globe continue to select this approach. In addition to exploring motivations, benefits, and cautions for designing with double skins, the book provides a primer on fundamental façade design concepts and strategies for control of thermal, luminous, and acoustic environments. Chapters also address alternative types of high-performance façades and implications for each phase of façade design and construction. Bioclimatic Double-Skin Façades promotes bioclimatic design that is inspired by nature, measured in performance, and uniquely adapted to climate and place. In-depth case studies illustrate how double-skin façades have been adapted to a range of climates and cultural settings: Marseille Library and Grenoble Courthouse in France, Cambridge Public Library in Massachusetts, Manitoba Hydro Place in Canada, and the Pearl River Tower in China.

This book was released on 2012-04 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In building facades, especially in case of office buildings usage of glass has become quite common. These facades provide a visual connectivity with the exteriors, enhance daylighting and provide better aesthetics for such spaces. Solar protection system for a glazed facade should control the direct solar radiation transmission and avoid the ill effects on occupant comfort. In this context, studies have been carried out in two open plan- conditioned office building of a warm humid climate. In situ experimental measurements accompanied by subjective surveys have been performed to evaluate the indoor thermal and lighting quality along with the performance of the glazing system. Comparative data is acquired from simulation studies for monthly variation in cooling energy with different double glazed windows. Experimental studies are performed to see the effect of sun control films as well as external shading over the double glazed glass in bringing down the heat gain. Parameters which influence the performance of double skin façade are discussed. Air velocities inside the shaft and heat fluxes are measured to determine the efficiency of the façade.

Available in PDF, EPUB and Kindle. Book excerpt: In order to mitigate the overheating problem in the warmer seasons, and thereby to improve thermal performance and energy efficiency of the Double-Skin Façade (DSF) system, this study introduced an innovative design approach involving the integration of thermal mass with the air channel of the conventional DSF. Then it proposed a numerical procedure to assess the thermal performance of DSF, and finally investigated the effect of thermal mass on the energy efficiency of such system. The initial step in the assessment procedure proposed the development of base-case models, which were able to predict temperature distribution in the DSF with a venetian blind. So too were the base-case models able to determine heating/cooling loads of the perimeter room for both the mechanically and naturally ventilated DSFs. In this procedure, building energy simulation software was used for base-case development; two distinct models were generated: an airflow model and a thermal model. The nodal, unidirectional airflow network method was applied in the case of the naturally ventilated DSF. The thermal model was a transient control volume method which found temperature distribution in discretized air-channel. The base-cases were verified at two levels: inter-model verification and verification relying on measurements from mechanically and naturally ventilated outdoor test-cells. At both levels, a generally fair agreement was obtained. After this, parametric studies pertaining to the energy performance of the system were conducted on the effect of thermal mass in unison with different air-channel configurations. Considerable energy load reductions were found when thermal mass was used in the air-channel, replacing venetian blind slats for mechanically ventilated DSFs; this held true during both summer and winter. In this configuration depending on the airflow path direction, energy savings from 21% to 26% in summer and from 41% to 59% in winter are achievable in compared with conventional DSF with aluminum venetian blind. The savings were found higher in sunny days than cloudy days. On the other hand, naturally ventilated DSFs combined with thermal mass were not found to be energy efficient in winter due to stack effect and airflow rate increase within the air channel.

Book excerpt: Double-skin facades open up new possibilities for clients and planners seeking creative new designs that are intelligently adapted to environmental conditions. This publication is the first to give a comprehensive treatment of the subject, providing both a theoretical framework for the use of this type of construction and numerous illustrations of practical examples. The book provides an in-depth study not only of issues such as acoustic and thermal insulation, aerophysics and facade construction, but also of the question of economic viability. Numerous illustrations and plans offer clear and precise insights into the construction of this new development in building design. Up to now double-skin facades have been used mainly for large buildings such as the debis headquarters on Potsdamer Platz in Berlin. They can be used, however, with equal success for smaller buildings as a means of reducing the ingress of external noise and improving ventilation.

Available in PDF, EPUB and Kindle. Book excerpt: The double-skin façade system (DSF) is a system consisting of two glass skins placed in such a way that air flows within the intermediate cavity. Without a good understanding of how the DSF performs, a complete appreciation of the interactive relationships between the envelope and equipment systems cannot be obtained. An extended experimental campaign in controlled climatic conditions was carried out on a full scale DSF. This experimental campaign was complete by a modelling and validation part which allowed the creation of a dedicated simulation platform for the study and the development of different control strategies.

Available in PDF, EPUB and Kindle. Book excerpt: The ventilated double skin facades are present in architectural world for a few decades now. During this time a lot of criticism was aimed at the dynamic facade concept arguing that its influence on indoor conditions and energy demand for cooling is not beneficial. In example a widely cited article by Gertis (1999) is reviewed in "A Critical Review of Double-Skin Facades" (LBNL, 2001) which is well known among the professional audience. The main goal of dissertation is to concentrate on elements of ventilated double skin facade, their properties, processes with which heat is transferred and the resulting influence that crucial building envelope component has on energy demand for heating and cooling and thermal comfort in indoor spaces. The described investigation brings information about the applicability of the dynamic facade concept to Ljubljana climate. The research is consisted of previous double skin facade exploration performed by Elisabeth Gratia and Andre de Herde; study of research executed in scope of the %Best Facade% project supported by European Commission; fieldwork executed in London and Ljubljana; a systematic parametric analysis of specific environmental strategies (their influence on heating and cooling demand) and finally the analysis of a unit performance from thermal comfort and energy demand perspective. The findings indicate that the considered typologies of ventilated double glazed facade (single storey and multi storey) will not ensure long term comfortable conditions in free-running mode, but they will reduce energy demand for both heating and cooling while providing comfortable conditions in comparison with single skin facade in supported mode. Thus its applicability to given context in climate of Ljubljana is assumed to be confirmed. The dissertation concludes by discussion of gained results in comparison with previous research and proposal for further research.

This book was released on 2002 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advocates for sustainable development have been campaigning for the implementation of green features in developments. New and high-technology energy-efficient technologies, such as photovoltaic cells and double skin façades, have been difficult to incorporate in developments even though they carry with them the promise of better performance and greater environmental impact. While some proponents of green development would have us believe that energy-efficient technologies are worthwhile investments, the truth is that the benefits do not always outweigh the costs. The key is promoting mass applications of these technologies is by providing an instrument for decision-makers to understand performance implications of building systems choices as represented by financial costs and benefits. It is through this holistic comprehension, as opposed to a dissection of development components, that risk perception can be mitigated and well-informed decisions can be made. This proposal presents a financial analysis of the implications of different façade. These systems will be applied to a similar base building with same performance specifications for a controlled comparison. The building type will be limited to commercial offices. It is important to note that the objective is not to arrive at an absolute cost valuation, but rather to cognize the relative efficiencies of one against the other. By using currency-based values as a representation of advantages and disadvantages, we are communicating in a common language familiar to decision-makers. This thesis hopes to achieve a better understanding of the efficiencies, or inefficiencies, of using high-technology façades. While the primary goal is to achieve a more accurate picture of the financial performances of high-technology energy efficient systems against conventional systems, the analysis will also give us a good understanding as to what barriers stand in the way, and what conditions have to exist for them to achieve widespread application. In the end, this could be the more valuable contribution.

Mehta and published by . This book was released on 2012 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: For achieving high performance building envelopes, the facade solution must have the capacity to respond and adapt to the variable exterior conditions and to changing occupant needs. The continuous challenge of designing the ideal building envelope lies in the ability to appropriately utilize the advancements of technology while reducing the building's overall energy consumption, achieving internal thermal comfort and qualitative user satisfaction. New trend driven by technological advances in to highly glazed facades and the general motivation for high quality green buildings, facade design alternatives have shifted towards dynamic building envelopes for optimal control of solar gains and daylight. Therefore developing a performance evaluation method of dynamic facades can be helpful to the building owners and designers in order to make informed envelope decisions for any particular climate and for any building type as to the value of these building concepts in meeting design goals for energy efficiency. The first objective of the study is to develop and incorporate sustainability integrated design process for achieving high performance envelope in the case of a tall office building for Charlotte Uptown. The Second and important objective of this study is to optimize dynamic shading configuration for optimal control of solar gain which would help offset building energy demand for cooling and/or heating. The major goal is to create a prototype that not only responds to the particular site, climate and building activity, but a method that can be applied to the building envelopes for any particular climate and for any building activity.
