Healthy and energy efficient buildings by Sunil K. Sansaniwal,Roberto Alonso González-Lezcano Pdf

This Research Topic on 'Healthy and Energy Efficient Buildings' focuses on the emerging need for sustainable and healthy indoor environments. The built environment contributes significantly to energy consumption and environmental degradation, leading to adverse effects on human health and well-being. Therefore, this Research Topic aims to bring together cutting-edge research that addresses the complex interplay between building energy efficiency and occupant health. The scope of the Research Topic covers topics such as energy efficiency, indoor environmental quality, sustainable energy, health and well-being, building codes and standards, energy management and green building practices. The ultimate goal of the Research Topic is to promote sustainable building practices and enhance the well-being of building occupants while reducing the environmental impact of buildings. While energy efficiency has become a top priority in building design, there has been less emphasis on creating indoor environments that are conducive to good health. To achieve the goal of this Research Topic, recent advances in building design, construction, and operation must be incorporated. These include the use of advanced materials and technologies, such as smart sensors and automation systems that can monitor and control indoor air quality, temperature, and lighting levels to create optimal indoor conditions for occupants. Additionally, the integration of renewable energy sources, such as solar and wind power, can help reduce the carbon footprint of buildings. In order to promote healthy buildings, there is a need for more research on the impact of building design and materials on indoor air quality and occupant health. This includes exploring the use of natural ventilation and passive cooling strategies, as well as the use of low-emitting materials and finishes that do not off-gas harmful chemicals. This Research Topic seeks to address the need for sustainable buildings that prioritize both energy efficiency and occupant health.

Optimal Lightweight Construction Principles by Federico Maria Ballo,Massimiliano Gobbi,Giampiero Mastinu,Giorgio Previati Pdf

This book presents simple design paradigms related to lightweight design, that are derived from an in-depth and theoretically sound analysis based on Pareto theory. It uses numerous examples, including torsion and inflated tubes, to fully explain the theories discussed. Lightweight Construction Principles begins by defining terms in relation to engineering design and optimal design of complex mechanical systems. It then discusses the analytical derivation of the Pareto-optimal set, before applying analytical formulae to optimal design of bent beams. The book moves through numerous case studies of different beam and tube construction including beams subject to bending, thin walled tubes under torsion and truss structures. This book will be of interest to researchers and graduate students in the field of structural optimisation and multi-objective optimization, as well as to practitioners such as design engineers.

Vibration of Structures and Machines by Giancarlo Genta Pdf

Addressing important practical aspects of nonlinear vibration analysis, this book presents cases rarely discussed in the existing literature yet are of considerable interest to researchers and practical engineers, such as rotor dynamics and torsional vibration of engines. The book can be used not only as a reference, but also as a graduate-level text, as it develops the subject from its foundations and contains problems and solutions for each chapter. The book begins with a discussion of vibrations in linear systems with one degree of freedom, providing a mathematical and physical basis for the subsequent chapters. Linear systems with many degrees of freedom serve to introduce the modal analysis of vibrations as well as some useful computational procedures. The book then turns to continuous linear systems, discussing both analytical solutions that provide physical insights as well as discretization techniques that supply tools for actual computation. The discussion of nonlinear vibrations includes a treatment of chaotic vibrations and other new insights. The book concludes with detailed discussions of the dynamics of rotating and reciprocating machinery.

Advanced Computational Vibroacoustics by Roger Ohayon,Christian Soize Pdf

Advanced Computational Vibroacoustics presents an advanced computational method for the prediction of sound and structural vibrations, in low- and medium-frequency ranges - complex structural acoustics and fluid-structure interaction systems encountered in aerospace, automotive, railway, naval, and energy-production industries. The formulations are presented within a unified computational strategy and are adapted for the present and future generation of massively parallel computers. A reduced-order computational model is constructed using the finite element method for the damped structure and the dissipative internal acoustic fluid (gas or liquid with or without free surface) and using an appropriate symmetric boundary-element method for the external acoustic fluid (gas or liquid). This book allows direct access to computational methods that have been adapted for the future evolution of general commercial software. Written for the global market, it is an invaluable resource for academic researchers, graduate students, and practising engineers.
