Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Advanced Computational Methods and Experiments in Heat Transfer XII written by B. Sundén and published by WIT Press. This book was released on 2012-06-27 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Assessment of Hygrothermal Performance and Design Guidance for Modern Light Frame Wall Assemblies written by Jay H. Crandell and published by . This book was released on 2017 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knowledge base on the topic of hygrothermal performance of building assemblies is as varied as it is vast. Although generally agreeing at the level of fundamental building science principles, this knowledge base can differ substantially in assumptions, analysis methodology, degree of completeness, treatment of material properties and boundary conditions, stringency of performance limit states or criteria, and judgments regarding acceptable or preferred solutions. These uncertainties contribute to confusion in the building design and construction marketplace regarding appropriate methods or best practices, particularly in view of implementing improved energy code requirements for the insulation of building envelopes. The confusion is amplified by gaps in the coordination of water-vapor control strategies in building codes and insulation strategies represented in energy codes. A comprehensive review and state-of-the-art evaluation is needed to better understand and resolve these real or perceived uncertainties while also identifying gaps where continual improvements can be offered or pursued with further research. This paper strives to provide such a review of U.S. and Canadian building code practices together with an assessment of data and findings from various modeling, test hut, and field studies on the hygrothermal performance of modern, light-frame building envelopes. It attempts to reconcile this information on a consistent basis and recommend incremental improvements to better unify current design and construction practices as represented in current U.S. and Canadian building codes. As a result of this effort, an attempt is made to formulate a reasonably comprehensive, consistent, and simple framework for the presentation of prescriptive guidance for design and construction of energy-efficient and durable building envelopes. Conclusions and recommendations for further research also are offered.
