Book Description
This book evaluates the potential of the combined use of district heating networks and cogeneration in the European Union (EU). It also proposes measures to remove barriers hindering their widespread implementation, formulates policies for their implementation, and evaluates their economic, energy, and environmental consequences. The book presents a preliminary assessment of the likely cost and the impact of widespread adoption of district heating networks and cogeneration carried out in three cities that represent the variety of climatic conditions in the EU. Based on this assessment, it is estimated that by undertaking the maximum economically feasible implementation across the EU, fuel savings of €95M/year would be achieved, representing energy savings of 6,400 petajoules (PJ), which is around 15% of the total final energy consumption in the EU in 2013 (46,214.5 PJ). Using simple and quick calculations and not specific software, the method used allows the evaluation of the potential benefits of retrofitting existing power plants into cogeneration plants and connecting them to nearby heating networks. In light of increasing energy costs and environmental concerns, the book is of interest to heating engineers, city planners, and policy-makers around the globe.

Book Description
This book focuses on spatial planning – an important determinant of energy saving and renewable energy supply. Revealing the key driving forces for spatial development supporting the shift towards energy efficiency and renewable energy supplies, it shows the importance of integrated spatial and energy planning approaches for a timely and sustainable change of energy systems, thus supporting policies of climate protection. As operating within the context of renewable energy sources is becoming a major policy issue at the international, European and national level, spatial dimensions of renewable energy systems as well as challenges, barriers and opportunities in different spatial contexts become more important. This book analyses not only the fundamental system interrelations between resources, technologies and consumption patterns with respect to energy, but also the links to the spatial context, and provides guidelines for researchers as well as practitioners in this new, emerging field. It presents innovative analytical tools to solve real-world problems and discusses the most important fields of action in integrated spatial and energy planning including planning contents, planning visions and principles as well as planning process design and planning methodology.

Book Description
With more and more concern being expressed over the Earth's dwindling energy resources as well as rising pollution levels, the subject of energy management and conservation is becoming increasingly important. Over half of all energy consumed is used in buildings so effective management of buildings whether commercial or domestic is vital. This book is a comprehensive text dealing with the theory and practice of the supply of energy to consumers, energy management and auditing and energy saving technology. It will be a core text on courses on energy management and building services, as well as updating professionals in the building sector.

Book Description
Conventional thermal power generating plants reject a large amount of energy every year. If this rejected heat were to be used through district heating networks, given prior energy valorisation, there would be a noticeable decrease in the amount of fossil fuels imported for heating. As a consequence, benefits would be experienced in the form of an increase in energy efficiency, an improvement in energy security, and a minimisation of emitted greenhouse gases. Given that heat demand is not expected to decrease significantly in the medium term, district heating networks show the greatest potential for the development of cogeneration. Due to their cost competitiveness, flexibility in terms of the ability to use renewable energy resources (such as geothermal or solar thermal) and fossil fuels (more specifically the residual heat from combustion), and the fact that, in some cases, losses to a country/region’s energy balance can be easily integrated into district heating networks (which would not be the case in a “fully electric” future), district heating (and cooling) networks and cogeneration could become a key element for a future with greater energy security, while being more sustainable, if appropriate measures were implemented. This book therefore seeks to propose an energy strategy for a number of cities/regions/countries by proposing appropriate measures supported by detailed case studies.

Book Description
District heating systems have the potential to contribute to the UK renewable energy targets. However, there are a number of economic barriers which would have to be addressed in order to make district heating competitive in comparison with alternative heating technologies. The objective of this research was to model and analyse a district heating network and develop an optimisation method to calculate the minimum capital investment, heat losses and pump energy consumption. Firstly, modelling and analysis of a district heating network was conducted to obtain district heating design cases with minimum annual total energy consumption, annual total exergy consumption and annualised cost. Then through the analysis, a two-stage programming model was developed which synthesised design and optimal operation of a district heating network. The optimisation was used to minimise annual total energy consumption, annual total exergy consumption or annualised cost of the heat network by selecting suitable pump and pipe sizes, taking into account different parameters such as target pressure loss, temperature regime and operating strategy. The optimisation technique was used to investigate two different case studies, with high and low heat density. In all cases, a variable flow and variable supply temperature operating method was found to be beneficial. Design cases with minimum annual total energy consumption and annualised cost used rather small pipe diameters and large pressure drops. To achieve the minimum annual total exergy consumption a design case with larger pipe diameters and smaller pressure loss was found to be desirable. It was observed that by reducing the water temperature and increasing temperature difference between supply and return pipes, the annual total energy consumption, annual total exergy consumption and the annualised cost were reduced. It was also shown that district heating in an area with high heat density is more energy efficient and cost effective.

Book Description
Geothermal waters, hot enough to provide direct heating, are available in many parts of the world. Some are exploited already but many more are only now being considered, as planners begin to recognize the environmental benefits of this unfamiliar energy resource. The relative economic benefits are more marginal, however, and a successful scheme requires careful design and optimization. The nature of geothermal resources imposes special conditions which may be unfamiliar to many plant engineers. In addition, many different approaches are possible, depending on the characteristics of the resource and the user and on the operator's requirements. Must the scheme be optimized for energy recovery or for financial return, or is it more important that it should remain profitable over as wide a range of conditions as possible? This book, written by professional plant engineers with first-hand experience, is designed to guide plant engineers through the different options and to help in this optimization process.

Book Description
Winner of Choice Magazine - Outstanding Academic Titles for 2007 Buildings account for over one third of global energy use and associated greenhouse gas emissions worldwide. Reducing energy use by buildings is therefore an essential part of any strategy to reduce greenhouse gas emissions, and thereby lessen the likelihood of potentially catastrophic climate change. Bringing together a wealth of hard-to-obtain information on energy use and energy efficiency in buildings at a level which can be easily digested and applied, Danny Harvey offers a comprehensive, objective and critical sourcebook on low-energy buildings. Topics covered include: thermal envelopes, heating, cooling, heat pumps, HVAC systems, hot water, lighting, solar energy, appliances and office equipment, embodied energy, buildings as systems and community-integrated energy systems (cogeneration, district heating, and district cooling). The book includes exemplary buildings and techniques from North America, Europe and Asia, and combines a broad, holistic perspective with technical detail in an accessible and insightful manner.

Book Description
This report identifies modern district energy as the most effective approach for many cities to transition to sustainable heating and cooling, by improving energy efficiency and enabling higher shares of renewables. This publication is one of the first reports to provide concrete policy, finance and technology best-practice recommendations on addressing the heating and cooling sectors in cities through energy efficiency improvements and the integration of renewables, both of which are central to the energy transition. These recommendations have been developed in collaboration with 45 champion cities, all of which use district energy, with 11 of them using it to achieve 100 per cent renewables or carbon-neutral targets.
