Available in PDF, EPUB and Kindle. Book excerpt: Exergy is the measurement of the amount of work capacity i.e. the amount of energy that can do work. The author applies this concept to ecology, where it can be used as an ecological indicator for ecosystem health assessment and this is presented in the book with illustrative examples. In addition, the question of how it is possible to define a special ecological exergy concept to calculate the exergy for models of ecosystems is covered. The use of exergy and an introduced fourth law of thermodynamics make it possible to understand the ecosystem reactions and how the ecosystem can grow in three different forms - biomass, complexity of network and information. From this analysis, it is clear why ecosystems are sustainable systems and what characteristic properties ecosystems have to ensure that sustainability. A parallel from ecosystems to society makes it possible to formulate the same rules (laws) for society. The concept of exergy as a health indicator measuring the degree of sustainability of society can also be used. Examples will be applied to illustrate the application of exergy and the deduced ecological rules (laws) for understanding the society.

Book excerpt: Thermo-ecology: Exergy as a Measure of Sustainability integrates thermo-ecology and exergy replacement cost as a new and original tool called thermo-ecology cost, or TEC. This tool allows for a more inclusive measurement of the impacts of using renewable and non-renewable resources by including the thermodynamics law in decision-making and presenting applications of this tool across industries and lifecycle assessments. It includes ways to investigate these effects more effectively by combining these critical aspects. This combination has emerged as a valuable decision-support tool for policymakers and the industry as they seek to evaluate the impacts of a product or process. Walks through what Thermo-Ecology Cost (TEC) is and why it gives a more holistic assessment when calculating the costs vs benefits of utilizing a natural resource Provides a new and more efficient way to measure and evaluate the sustainability of resources Includes: TEC calculation examples to explain the TEC theory as well as to help readers prepare their own analyses devoted to exergo-ecological applications across industries including energy production and waste management Demonstrates the potential of TEC usage for applications like ecological taxes proportional on TEC

Available in PDF, EPUB and Kindle. Book excerpt: Many people, professionals and non-professionals alike, recognize that it is of critical importance to solve global energy and environmental issues. For this purpose, it is essential to have a scientific understanding of what is meant by the “energy” issue is and the “environmental” issue. The concept of “exergy” is a scientific concept that exactly fits. The concept of ‘energy’ is a scientifically-well established concept, namely ‘to be conserved’. Then the question is what is really consumed. Exergy: Theory and Applications in the Built Environment is dedicated to answer this fundamental question by discussing the theory of “exergy” and by demonstrating its use extensively to describe a variety of systems in particular for built-environmental conditioning. Our immediate environmental space works within the flow of energy and matter in an “exergy-entropy” process, and the built environment can be designed with these energy & environmental issues in mind. Exergy: Theory and Applications in the Built Environment introduces readers who are not familiar with thermodynamics to the concept of exergy with a variety of discussion on the built-environmental space such as heating, cooling, lighting, and others. Readers, including students, researchers, planners, architects and engineers, will obtain a better picture of a sustainable built-environment.

Book excerpt: The exergy method makes it possible to detect and quantify the possibilities of improving thermal and chemical processes and systems. The introduction of the concept thermo-ecological cost (cumulative consumption of non-renewable natural exergy resources) generated large application possibilities of exergy in ecology. This book contains a short presentation on the basic principles of exergy analysis and discusses new achievements in the field over the last 15 years. One of the most important issues considered by the distinguished author is the economy of non-renewable natural exergy. Previously discussed only in scientific journals, other important new problems highlighted include: calculation of the chemical exergy of all the stable chemical elements, global natural and anthropogenic exergy losses, practical guidelines for improvement of the thermodynamic imperfection of thermal processes and systems, development of the determination methods of partial exergy losses in thermal systems, evaluation of the natural mineral capital of the Earth, and the application of exergy for the determination of a pro-ecological tax.A basic knowledge of thermodynamics is assumed, and the book is therefore most appropriate for graduate students and engineers working in the field of energy and ecological management.

Available in PDF, EPUB and Kindle. Book excerpt: Growing concerns about the environmental and ecological implications of industrial and other systems, as well as the impact of energy resource utilisation, are fostering increasing interest in environmental and ecological protection. Such understanding is crucial to advancing the quest for a cleaner environment and sustainability. New approaches to ecology and the environment that provide an engineering perspective and a scientific basis to activities are of particular interest. The integration of the thermodynamic quantity exergy with the environment and ecology provides a novel approach that offers significant potential to improve environmental and ecological management. A brief summary is presented here of existing analysis techniques which integrate exergy with ecological and environmental factors.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents a consistent and complete ecosystem theory based on thermodynamic concepts. The first chapters are devoted to an interpretation of the first and second law of thermodynamics in ecosystem context. Then Prigogine's use of far from equilibrium thermodynamic is used on ecosystems to explain their reactions to perturbations. The introduction of the concept exergy makes it possible to give a more profound and comprehensive explanation of the ecosystem's reactions and growth-patterns. A tentative fourth law of thermodynamic is formulated and applied to facilitate these explanations. The trophic chain, the global energy and radiation balance and pattern and the reactions of ecological networks are all explained by the use of exergy. Finally, it is discussed how the presented theory can be applied more widely to explain ecological observations and rules, to assess ecosystem health and to develop ecological models.

Available in PDF, EPUB and Kindle. Book excerpt: Analyzing the self-sufficient Danish island of Samsø, this book explains sustainability through a bio-geophysical understanding of how to best use society’s limited resources to achieve true sustainability. The method used derives from the thermodynamic function of exergy. By analyzing exergy flows and establishing a system for evaluating the energy and the materials used in a society, the author creates a platform for monitoring certain indicators of sustainability. These indicators inform readers about the actions that must be taken and the time frames for achieving sustainability goals. The exergy-based approach is an important tool for carrying out such an analysis because it Focuses on several key thermodynamic concepts and the usefulness of exergy analysis for evaluating sustainability Explains sustainability by implementing thermodynamic laws to societal consumption and the use of resources Discusses new methods that integrate energy and material fluxes and evaluates them against each other Provides direct indicators for finding the largest problems/obstacles and deciding where measures should be taken Includes instructions on how to establish an accounting system for evaluating the energy and the materials used in a society This book is aimed for professionals, researchers, and students working on nature conservation and environmental management projects related to sustainability.
