Book Description
Containing papers presented at the twelfth in a series of successful international conferences on Advanced Computational Methods and Experiments in Heat Transfer, this book covers the latest developments in this important field. Heat Transfer plays a major role in emerging application fields such as sustainable development and the reduction of greenhouse gases, as well as micro- and nano-scale structures and bio-engineering. Typical applications include heat exchangers, gas turbine cooling, turbulent combustion and fires, electronics cooling, melting and solidification. The nature of heat transfer problems is complex, involving many different simultaneously occurring mechanisms (e.g., heat conduction, convection, turbulence, thermal radiation. phase change). Their complexity makes it imperative that we develop reliable and accurate computational methods to replace or complement expensive and time-consuming experimental trial and error work. Tremendous advances have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and more powerful computers capable of performing efficient and rapid calculations. Nevertheless, to further progress, it will also be necessary to develop theoretical and predictive computational procedures--both basic and innovative--and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. The book includes such topics as: Heat Transfer in Energy Producing Devices; Heat Transfer Enhancement; Heat Transfer Problems; Natural and Forced Convection and Radiation; Multiphase Flow Heat Transfer; Modelling and Experiments.

Book Description
Buildings account for 35 percent of the world s energy use and a similar percentage of CO2 emissions. In order to ensure adequate energy supplies and to curtail the growth of CO2 emissions, it is essential that building energy consumption is significantly reduced. One way this can be achieved is through the introduction of sustainable building design enabled by innovative building simulation tools, for example the whole building heat, air and moisture (HAM) transfer model. The hygrothermal transfer between building envelopes and indoor air has a significant influence on the indoor environment and energy performance of buildings. However in most applications, building envelope designers attempt to predict the hygrothermal performance of an individual building element by uncoupling the system from interactions of the other envelope components to both indoor/outdoor environments. A more advanced building performance evaluation approach requires the direct coupling of all building envelope systems with HVAC systems and indoor/outdoor environments. The book will focus on the development of a coupled HAM model for whole building simulation.

Book Description
One in three homes, on average, suffer from excessive dampness and mould proliferation, with significant health and economic impacts. The combination of new construction methodologies, stricter airtightness requirements and the changing social and cultural context that influences the way we live inside buildings has created unprecedented challenges for the built environment. In modifying indoor and outdoor environments and the building envelopes that serve as a filter between the two, we are changing the physical parameters of the ways in which buildings behave and respond to climatic stimuli. Understanding and predicting the way in which buildings and moisture may interact should be an important step in the design process, aiming to minimise possible negative long-term consequences. Understanding and predicting the way in which buildings and moisture may interact is, today more than ever, essential yet difficult, as the experience of the past has lost its applicability. Moisture-related issues never have a simple solution, since they involve multiple factors, including design, construction, maintenance, materials, climate and occupation pattern. Thus, while the topic is attracting growing attention among researchers, designers and practitioners, the pace with which actual change is occurring is still too slow. Moisture and Buildings provides a critical overview of current research, knowledge and policy frameworks, and presents a comprehensive analysis of the implications of moisture and the importance of accounting for it during the design process. It responds to the urgent need for a systematic organization of the existing knowledge to identify research gaps and provide directions for future developments. The ultimate goal is to increase awareness of the multifaceted implications of hygrothermal phenomena and promote integrated design processes that lead to healthier and more durable constructions. Presents advanced knowledge on hygrothermal processes and their interaction with buildings Integrates the three key areas of moisture transport and its impact on buildings, including durability, human health and comfort Considers the most useful computational tools for assessing moisture and building interactions Includes a section on the main European, American and Australian building codes Explains the risks of mold growth to human health, including growth models to assessment methods

Book Description
To prevent the building envelope from moisture-related damages, it is essential to predict the building envelope's hygrothermal performance through a scientific approach, and further to improve the design and construction. In this thesis, an advanced numerical tool (HAM-BE) was developed to simulate the combined heat, air and moisture (HAM) transport in the building envelope. The state of the art knowledge of heat and mass transfer in building materials was applied. The major features of HAM-BE are: multi-dimensional and transient coupling of heat and moisture transport; air convection integrated in hygrothermal simulation through Darcy-Boussinesq approximation; heat transfer mechanisms of conduction and convection of sensible and latent heat; moisture transport mechanisms of vapor diffusion, capillary suction and air convection; material database of common building materials in North America; experimental settings or hourly weather data as boundary conditions; and setting moisture loading inside the materials or along the surfaces of the building envelope's hidden or exposed components to simulate the wetting process. A commercial finite element solver was chosen to solve the governing partial differential equations (PDEs) of hygrothermal transport. This approach provided building science researchers the flexibility to build, modify, and maintain their modeling work efficiently. Validation of HAM-BE included inter-model comparison with benchmarking cases of the HAMSTAD project and comparison between numerical simulation with data of the Collaborative Research and Development (CRD) project measured by fellow students under the supervision of Drs Fazio and Rao. Through validation work, HAM-BE was proven to have great potential as an accurate and reliable research tool for the building envelope study. As the extension of the CRD investigation, parametric study was carried out to estimate the drying performance of wood-frame walls under the climatic conditions of Montreal and Vancouver. It is demonstrated that the climate condition has the most significant influence to the drying process of the wet components in wall assemblies. The drying process occurs mainly in the summer season, and is largely restrained in the winter season. To improve outward drying, the cladding materials should have high vapor permeance, especially the sheathing membrane. The sheathing board with higher vapor permeance also facilitates drying. Under the investigated climates, the polyethylene vapor barrier at the warm side of the wall is not beneficial, rather restricts the possibility of inward drying.

Book Description
When used appropriately, building performance simulation has the potential to reduce the environmental impact of the built environment, to improve indoor quality and productivity, as well as to facilitate future innovation and technological progress in construction. Since publication of the first edition of Building Performance Simulation for Design and Operation, the discussion has shifted from a focus on software features to a new agenda, which centres on the effectiveness of building performance simulation in building life cycle processes. This new edition provides a unique and comprehensive overview of building performance simulation for the complete building life cycle from conception to demolition, and from a single building to district level. It contains new chapters on building information modelling, occupant behaviour modelling, urban physics modelling, urban building energy modelling and renewable energy systems modelling. This new edition keeps the same chapter structure throughout including learning objectives, chapter summaries and assignments. Moreover, the book: • Provides unique insights into the techniques of building performance modelling and simulation and their application to performance-based design and operation of buildings and the systems which service them. • Provides readers with the essential concepts of computational support of performance-based design and operation. • Provides examples of how to use building simulation techniques for practical design, management and operation, their limitations and future direction. It is primarily intended for building and systems designers and operators, and postgraduate architectural, environmental or mechanical engineering students.
