Due to changes in lifestyle, people spend more time indoors. This refers not only to the time spent at home and at office premises, but also in shopping malls, recreation centers and transport vehicles. Concentrations of many pollutants are higher indoors than they are outdoors. Consequently, the indoor environment has a bigger impact on human health, well being and effectiveness.

Indoor Environment Engineering is a relatively new scientific discipline with an interdisciplinary character, using knowledge from chemistry, biology, medicine and engineering. Since the early 1990s, the number of studies in this area has grown significantly from research on indoor air parameters, new emerging pollutants in indoor air, energy saving systems of heating, to studies on ventilation and air-conditioning in buildings. Even though much progress has been made since then, a number of questions still remains open:

• How can indoor air quality be measured? What are reliable, time- and cost-efficient methods?
• How can indoor air quality be improved, investing as little energy as possible?
• How to minimize secondary pollution caused by air supply systems?
• Which type of pollutants should research focus on?
• In what way are we exposed to new pollutants (plasticizers, ?ame retardants, pesticides)? What is their impact on our health?

Management of Indoor Air Quality is a collection of 14 peer reviewed papers in Indoor Environment Engineering addressing the above issues. It includes research on HVAC impact on aerosol levels, new ventilation systems as well as air quality problems in new environments. The volume is intended for scientists, engineers, post-graduate and graduate students interested in the area of indoor environment.

In the past, boundary conditions in the building of dams have changed, as technological developments have been influential on dam planning, construction, operation and maintenance processes. It is ICOLD's mission to not only consider these developments but also adequately deal with environmental aspects and related infrastructure issues. Altered water cycles, more extreme weather conditions and an increasing number of natural hazards clearly affect the safe and economical operation of dams and reservoirs. Moreover, emission-free hydropower production as the most important form of "liquid" solar energy and the provision of water for irrigation and potable water supply is becoming more and more important to meet the world's fast growing demand for energy and food in a sustainable way. Dams and Reservoirs Under Changing Challenges covers subjects ranging from dam engineering through the benefits and drawbacks of dams, including the latest developments dealing with dams and reservoirs under changing environmental and socioeconomic conditions. It is a valuable resource for professional and dam engineers, water manager, governmental organizations and commercial consultants responsible for dam design and management.

In recent years, a number of global claims have failed because they were presented without any systematic analysis, justification or proper calculation of losses. Hence, "Global Claims in Construction" highlights these issues as well as the importance of understanding causation, factual necessity and the courts' attitude and approach to global claims.
"Global Claims in Construction" addresses the principles of global claims and their calculation methodologies in detail through extensive references to literature, case law and a real world case study. It aims to be a valuable resource for professionals working in the construction industry, as well as students in construction and engineering."

The main goal of this introductory course is to demonstrate how basic concepts in soil mechanics can be used as a "forensic" tool in the investigation of geotechnical failures. This, in turn, provides a good opportunity to show how to use available procedures in the formulation of useful simple geotechnical models. Geotechnical failure is understood here in a broad sense as the failure of a structure to function properly due to a geotechnical reason.

Some of the geotechnical failures selected are well known for their impact on the geotechnical community. Others are closer to the authors' experience. They have been organized into three main topics: Settlement, Bearing Capacity and Excavations. They cover a significant proportion of every day activities of professional geotechnical engineers. No attempt has been made to create a comprehensive handbook of failures. Instead, the emphasis has been given to creative applications of simple mechanical concepts and well known principles and solutions of Soil Mechanics. The book shows how much can be learned from relatively simple approaches. Despite this emphasis on simplicity, the book provides a deep insight into the cases analyzed. A non-negligible number of new analytical closed-form solutions have also been found. Their derivation can be followed in detail.

In all the cases described an effort was made to provide a detailed and step by step description of the hypothesis introduced and of the analysis performed.

Each of the eight chapters of the book addresses a certain type of failure, illustrated by a case history. The chapters are self-contained. They provide a review of soil mechanics principles and methods required to understand and explain the failure described. In some cases the analysis offered provides a non-conventional application of basic principles. All chapters are completed with a summary of lessons learned from the failure and its analysis. They also include a short account on advanced topics to help the interested readers to go beyond the approaches used in the book.

Readers are expected to be familiar with the basic concepts of soil mechanics and foundation engineering. The target audience is graduate students, faculty and practicing professionals in the fields of civil and geotechnical engineering.

This textbook profits from experience accumulated in teaching a course in forensic engineering at the ETH Zurich.

With its uncommon presentation of instructional material regarding mathematical modeling, measurements, and solution of inverse problems, Thermal Measurements and Inverse Techniques is a one-stop reference for those dealing with various aspects of heat transfer.

Progress in mathematical modeling of complex industrial and environmental systems has enabled numerical simulations of most physical phenomena. In addition, recent advances in thermal instrumentation and heat transfer modeling have improved experimental procedures and indirect measurements for heat transfer research of both natural phenomena and manmade applications. These new resources and methods help theoretical, computational, and experimental researchers synergistically interact to better understand the physical phenomena being studied. This book explores how inverse analysis can be used to increase understanding of interactions between technological systems and nature, by bridging the gap between data derived from measurements and information from theoretical predictions.

Assembled in three parts?Modeling and Measurements in Heat Transfer, Inverse Heat Transfer Problems, and Applications?this self-contained resource:

• Explores theoretical background and examples
• Outlines practical applications, including sample test cases
• Presents inverse techniques to estimate spatially and time-varying functions (such as heat sources, fluxes, and thermophysical properties), as well as constant parameters in heat transfer problems

Written by international experts, this book assumes basic heat transfer knowledge, presenting a balanced approach suitable for advanced undergraduates and graduate students, as well as practicing engineers and academic and industrial researchers. With coverage of modeling at the micro- and nanoscales, this book covers classic and novel approaches to help readers understand and solve heat transfer problems of all kinds.

This book outlines a methodology for producing macro recycled polypropylene (PP) fibres with optimal mechanical properties and illustrates the reinforcing effects of recycled PP fibres in concrete. It describes the great potential of using these fibres in concrete applications such as footpaths and precast elements. Further, it sheds new light on the environmental impacts of using recycled PP fibres, which are evaluated by means of cradle to gate life cycle assessment based on the Australian context. The use of recycled PP fibre not only helps reduce consumption of virgin materials like steel or plastic but also provides an attractive avenue for recycling plastic waste. The book will appeal to engineers, governments, and solid waste planners, and offers a valuable reference for the plastic waste recycling and plastic fibre reinforced concrete industries.

This book contains an overview of the most relevant scientific contributions of Gerard de Josselin de Jong to the development of both Soil Mechanics and Transport in Porous Media. The volume comprises a selection of papers by de Josselin de Jong as they were published in the international scientific literature. In addition, some unpublished, but highly relevant work has been included.

Most of the papers by de Josselin de Jong are concerned with issues related to soil mechanics. This is not surprising, considering the fact that he worked at Delft Soil Mechanics Laboratory and given the nature of his chair at Delft University of Technology. But occasionally he made an excursion to the area of flow and transport in porous media. It characterizes his ingenuity that most of these excursions led to papers that are now classics in the field.

The editors have chosen to divide his key publications into a group devoted to soil mechanics and a group devoted to flow and transport in porous media. The selected papers were published in the period 1950-1990. They clearly demonstrate the development of ideas and the profound contributions of de Josselin de Jong. Each paper is a jewel on its own. He has an extremely original way of reasoning and he illustrated intricate concepts and mechanisms with the aid of his famous hand-made drawings. In particular young scientists will enjoy reading these papers because important parts of today's porous media research find their roots in them, and because many questions raised by de Josselin de Jong are still open and subject to current investigations.

A successful construction business is a knowledge business. And knowledge must be managed effectively to be used efficiently, especially in a complex project-oriented business such as construction, where skills acquired and lessons learned on one project need to be applied to the next. A holistic approach to knowledge management (KM) is taken in this book to incorporate all of the relevant themes, tackling technological, socio-cultural and organisational issues, with the creation of value as a focus throughout. Information is drawn from a broad range of sources to explain core theories and provide guidance on practical application. Topics covered include: * changing business relationships in a knowledge economy; * knowledge creation processes and theories; * data, text and knowledge mining techniques; * the learning construction organisation; * future technology for knowledge management. Written by the authors of the first EU-funded KM research project in the field of construction, this textbook is uniquely well-researched, and is the perfect introduction to KM for students across the built environment. It is also a crucial guide to the topic for practitioners.

The book offers a general introduction to timber poles as a construction material. Timber poles have served throughout history as a low-cost, environmentally friendly and structurally efficient building resource. As a result of the establishment of both commercial plantations and community forestry programs worldwide, the availability of forestry thinnings for poles is rapidly increasing and the potential for their use has never been greater.The book covers the processes of harvesting and protecting the poles through to specific applications in the construction of domestic and industrial buildings, and other types of construction such as bridges and retaining walls. Key areas of preservation and jointing are addressed in detail and there are illustrations throughout. This manual intends to be descriptive rather than prescriptive, providing ideas that can be developed into solutions depending on specific circumstances and a number of case studies show some ideas put into action.This new edition will be a useful guide not only to field practitioners in housing and construction projects, but will also be of interest to the non-specialist.

This book discusses the application of independent continuous mapping method in predicting and the optimization of the mechanical performance of buckling with displacement, stress and static constrains.

This book contains papers presented at the 1st International Conference on Timber Structures, which was held in collaboration with the Technical Centre of Wood Industry in Belgium. It explores the latest developments in wood products and their application as structural components. The focus of the included works is to draw attention to new research and real applications from both researchers and practitioners, and to present new and innovative ideas in this significant field. Rapid advances have recently been made in the development and processing of innovative ecologically friendly wood products. A variation of new structural shapes can now be fabricated and used to construct buildings and bridges that have minimal impact on the environment. Wood is particularly appealing since it is renewable and has no carbon footprint when it is harvested in a sustainable way. Timber structures are ecologically sound and comparatively low cost. The material lends itself to ground-breaking designs and new types of composites offer reliable, robust and safe materials. The content of this book comprises a range of topics: Material properties of wood; Durability aspects, service life modelling; Fire safety of timber structures; Protection against decay; Non-destructive inspection and monitoring; Glued, laminated structures, Xlam and CLT; Timber joints and connections; Vernacular wood and heritage timber structures; Timber housing and eco-architecture; Timber bridges; Large span timber roof structures; Shell structures in timber; Mixed, composite and hybrid structures; Computational analysis and experimental methods; Structural engineering and design; Seismic behaviour of timber structures; Protection of timber; Repaired timber structures; Rapidly assembled and transferable timber structures; Guidelines, codes and regulations; Structural failures; Art and craftsmanship.

Since the spread of classical design and construction amongst the upper echolons of British society in the late seventeenth century, traditional construction methods have largely fallen by the wayside. Centuries later, as the construction industry faces up to its environmental responsibilities, this book explores its rich and ancient tradition to provide tried and trusted solutions to modern day construction problems.

By way of introduction, the ancient and historical lifestyles that dictated the nature of traditional construction are explored, before focussing on its health and ecological benefits. As well as cultural background, this book includes a detailed scientific description of traditional building materials and their constituents which draws a sharp contrast with modern petrochemical-based materials. The studies of traditional buildings included reveal the sustainability of features such as natural ventilation and breathing walls, and comparisons with modern construction methods show how they could prevent 'sick building syndrome'. The author argues that maintenance for long life, by contrast with the modern concept of life-cycle costing, is at the nub of sustainability and underlies the contribution traditional building construction can make to tackling climate change.

Over 250 original photos, and over fifty bespoke diagrams illustrate the features, techniques, and characteristics of traditional construction that could make such a valuable contribution to the industry today. The inclusion of a close study of how these methods relate to British building regulations makes this book a practical guide for construction professionals, as well as an authoritative resource for students and policy-makers.

This book describes exemplary selected projects carried out in the Trentino-Alto Adige region (Italy) exploring numerous building-integrated photovoltaics (BIPV) systems (i.e. modules, construction system, energy systems). It presents 18 case studies analyzing three aspects of PV integration: aesthetic, energy and technology, with information on decision-making, design process and lessons learnt given for each, along with several pictures, including of general system and architectural details. Based on interviews with architects and engineers, experts from facade/glass manufacturers, energy consultants, BIPV experts, PV installers, electricians, private and public building owners and real estate companies, the book provides a source of inspiration and technical knowledge for architects and engineers towards an increased use of PV in architecture.

The performance of irrigation schemes that carry sediment laden water is often poor. Modern irrigation schemes are increasingly demand based, which means that the water flow in the canals is determined by the crop water requirements. Accordingly the flow in the canal network is not constant as the crop water requirement changes with the climate and the growing stages. Also the inflow of the sediment is not constant throughout the irrigation season. Such schemes, particularly having unlined canals in alluvial soils, are difficult to design and to manage without compromising the flexibility or maintenance cost. This research has made an in-depth assessment on the role of sediment in the design and management of an irrigation scheme by using the data of Sunsari Morang Irrigation Scheme, Nepal. An analysis of the velocity and shear stress distribution across a non-wide trapezoidal canal has been made to derive the correction factor for the sediment transport predictors.

• the structure of the construction industry
• the nature of clients
• the historical development of building procurement methods
• the roles and responsibilities carried out in any project.

Having developed the necessary background knowledge, the reader is then introduced to the more complex aspects of procurement in detail, such as:

• methods of paying contractors
• the main procurement routes in use
• standard forms of contract.

The concluding chapter discusses emerging procurement trends, and speculates on future developments to bring the reader right up to speed with the modern industry. With its clear layout and highly accessible approach, Introduction to Building Procuremen is the perfect introductory text for undergraduate students and professionals starting out on a career in quantity surveying, construction project management or construction commercial management.

This book provides the readers with a timely guide to the application of biomimetic principles in architecture and engineering design. As a result of a combined effort by two internationally recognized authorities, the biologist Werner Nachtigall and the architect Goeran Pohl, the book describes the principles which can be used to compare nature and technology, and at the same time it presents detailed explanations and examples showing how biology can be used as a source of inspiration and "translated" in building and architectural solutions (biomimicry). Even though nature cannot be directly copied, the living world can provide architects and engineers with a wealth of analogues and inspirations for their own creative designs. But how can analysis of natural entities give rise to advanced and sustainable design? By reporting on the latest bionic design methods and using extensive artwork, the book guides readers through the field of nature-inspired architecture, offering an extraordinary resource for professional architects, engineers, designers and urban planners, as well as for university teachers, researchers and students. Natural evolution is seen throughout the book as a powerful resource that can serve architecture and design by providing innovative, optimal and sustainable solutions.

The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts have taken a fragmented approach to deal with the challenges facing subsistence farmers in rainfed systems. The research has been conducted in the semi-arid Makanya catchment of northern Tanzania and has successfully applied different analytical techniques to better understand soil and water interactions at field scale. It has been demonstrated that there is indeed scope to increase crop water productivity provided the local farmers adopt more efficient cultivation techniques. Substantial yield increases occur as a result of diverting runoff and these further improve when other techniques such as ripping, application of manure and cover cropping are introduced. This confirms that no single solution exists to solve the problem of low yields in rainfed farming systems. However, even with these promising results, the research has shown that there is room to further improve the efficiency of crop water use through improvement in research approaches and exploration of better techniques.

This handbook provides a complete and detailed overview of piling systems and their application. The design and construction of piled foundations is based on Eurocode 7 and DIN 1054 edition 2010 as well as the European construction codes DIN EN 1536 (Bored piles), DIN EN 12699 (Displacement piles) and DIN EN 14199 (Micropiles). These recommendations also deal with
- categorisation of piling systems,
- actions on piles from structural loading, negative skin friction and side pressure,
- pile resistances from static and dynamic pile test loading as well as extensive tables with the pile load-bearing capacity of nearly all piling systems based on values from practical experience,
- pile groups,
- performance of static and dynamic test loading and integrity tests,
- load-bearing behaviour and verifications for piles under cyclical, dynamic and impact actions
- quality assurance for construction.
An appendix with numerous calculation examples completes the work.
As part of the approval procedure for offshore wind energy structures, the Federal Office for Shipping and Hydrography (BSH) demands verifications according to the new Chapter 13 ("Load-bearing behaviour and verifications for piles under cyclical, dynamical and impact actions") of the EA Pfahle (the recommendations of the Piling working group - 2nd edition), which deals with external pile resistance for the foundations of offshore wind energy structures and the types of verifications to be provided under cyclical actions.
The publication of the EA-Pfahle recommendations by the Piling working group of the German Society for Geotechnics (DGGT), which works with the same members as the piling standards committee NA 00-05-07, is intended to provide assistance for engineers active in the design, calculation and construction of piled foundations. The recommendations can thus be considered as rules of the technology and as a supplement to the available codes and standards.
