EBOOK SYNOPSIS:

Towards Nearly Zero Energy: Urban Settings in the Mediterranean Climate discusses tactics that can be used to effectively reduce energy consumption towards zero energy. With energy usage in buildings accounting for over 40% of primary energy use and 24% of greenhouse gas emissions worldwide, this remains an unavoidable objective. The book looks at the life of the systems of energy production from renewable sources amidst the exceptionally challenging global economic crisis that the Mediterranean areas and other societies are currently experiencing. By using an innovative and interdisciplinary approach of socio-oriented technological design, the book indicates tools and measures that can be developed at the public, legislative, and market levels to counterbalance the large pay-back times of energy efficiency measures. In particular, the book displays guidelines and best practices to activate new forms of economic incentives in order to attract potential investors that demonstrate that a large set of possible solutions is technically feasible to achieve nearly zero energy, even in high energy consuming circumstances and urban settings. Furthermore, by discussing and comparing the economic and energy impact of different technology options, this work offers guidelines and best practices to activate new cost-effective forms and social incentives in order to attract both potential investors and motivate the urban stakeholders toward nearly zero energy. Strategies and zero energy solutions for practitioners Policy s and economic resolutions to combat legislative barriers Examples and case studies of nearly zero energy urban environments

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

This book addresses the main challenges in implementing the concepts that aim to replace the regular fossil-fuels based energy pattern with the novel energy pattern relying on renewable energy. As the built environment is one major energy consumer, well known and exploited by each community member, the challenges addressing the built environment has to be solved with the consistent contribution of the community inhabitants and its administration. The transition phase, which already is under implementation, is represented by the Nearly Zero Energy Communities (nZEC). From the research topics towards the large scale implementation, the nZEC concept is analyzed in this book, starting with the specific issues of the sustainable built environment, beyond the Nearly Zero Energy Buildings towards a more integrated view on the community (Chapter1) and followed by various implementation concepts for renewable heating & cooling (Chapter 2), for renewable electrical energy production at community level (Chapter 3) and for sustainable water use and reuse (Chapter 4). As the topic is still new, specific instruments supporting education and training (Chapter 5) are needed, aiming to provide the knowledge that can drive the communities in the near future and is expected to increase the acceptance towards renewable energy implemented at community level. The sub-chapters of this book are the proceedings of the 5th edition of the Conference for Sustainable Energy, during 19-21 October 2017, organized by the R&D Centre Renewable Energy Systems and Recycling, in the R&D Institute of the Transilvania University of Brasov. This event was organized under the patronage of the International Federation for the Science of Machines and Mechanisms (IFToMM) - the Technical Committee Sustainable Energy Systems, of the European Sustainable Energy Alliance (ESEIA) and of the Romanian Academy of Technical Sciences.

ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Cost optimal and nearly zero energy performance levels are principles initiated by the European Union’s (EU) Energy Performance of Buildings Directive which was recast in 2010. These will be major drivers in the construction sector in the next few years, because all new buildings in the EU from 2021 onwards are expected to be nearly zero energy buildings (nZEB). This book introduces the technical definitions, system boundaries, energy calculation methodology and input data needed to set primary energy based minimum/cost optimal and nZEB requirements in national energy frames. Worked examples are provided to illustrate the calculation of delivered, exported and primary energy, and renewable energy contribution. Five case studies of high performance nZEB office buildings across Europe are reported to show alternative technical solutions and to draw some general design rules based on completed nZEB buildings. Specific features of the nZEB design process, especially in the early stages, and architectural competitions are included. These describe important design issues in the scoping and conceptual design phase, allowing design streams to be controlled so that specified targets can be met. This book is intended for readers who need to be aware of or are working with the energy performance of buildings – for decision makers in public and private sectors, architects, engineers, construction clients, consultants, contractors, manufacturers and students. The editor of this book, Professor Jarek Kurnitski has made major contributions to the preparation of the European REHVA nZEB technical definition and has developed energy calculation frames for current Estonian and Finnish energy performance regulations. He is the leader of nZEB research at Tallinn University of Technology in Estonia and Aalto University in Finland, and he has over 300 publications.

EBOOK SYNOPSIS:

Abstract: On the behalf of reaching EU directive 2010/31/EU energy performance targets and fulfilling nearly zero-energy energy buildings (nZEB) requirements by the end of 2020, utilization of renewable energy sources becomes important. Renewable solar and ground energy can be efficiently utilized by a hybrid geothermal heat pump with a solar thermal storage, which is expected to yield high seasonal coefficient of performance (SCOP) making it attractive to consider in nZEB design. This numerical study investigates the impact of various ground heat exchangers and thermal storage options along with their possible combinations on heat pump plant heating/cooling performance in the design of commercial hall-type nZEB located in cold climate of Hämeenlinna, Finland. Components applied in a numerical study were energy piles, vertical boreholes (heat wells), solar collector and/or exhaust air heat as a thermal storage source. A whole year dynamic simulations were performed in IDA-ICE simulation environment, where detailed custom ground-source heat pump (GSHP) plants were modelled. Results revealed GSHP plant to be favorable heat source option in nZEB design. Application of thermal storage enabled to reduce energy piles field by more than two times. Proposed exhaust air thermal storage option performed highly efficient in comparison to solar thermal storage.

EBOOK SYNOPSIS:

Abstract : Purpose: The purpose of this study was to design a renovation plan for a university campus building (Department of Electrical and Computer Engineering) with the aim to achieve nearly zero energy performance, ensuring a low specific demand (lower than 44 kWh/m 2 ) and a high level of on-site renewable generation (equivalent to more than 20 per cent of the energy demand). Design/methodology/approach: The baseline demand was characterized based on energy audits, on smart metering data and on the existing building management system data, showing a recent reduction of the electricity demand owing to some implemented measures. The renovation plan was then designed with two main measures, the total replacement of the actual lighting by LEDs and the installation of a photovoltaic system (PV) with 78.8 kWp coupled with an energy storage system with 100 kWh of lithium-ion batteries. Findings: The designed renovation achieved energy savings of 20 per cent, with 27.5 per cent of the consumed energy supplied by the PV system. This will ensure a reduction of the specific energy of the building to only 30 kWh/m 2, with 42.4 per cent savings on the net-energy demand. Practical implications: The designed renovation proves that it is possible to achieve nearly zero energy goals with cost-effective solutions, presenting the lighting renovation and the solar PV generation system a payback of 2.3 and 6.9 years, respectively. Originality/value: This study innovated by defining ambitious goals to achieve nearly zero energy levels and presenting a design based on a comprehensive lighting retrofit and PV generation, whereas other studies are mostly based on envelope refurbishment and behaviour changes.

EBOOK SYNOPSIS:

The Green Solar Cities, EU-Concerto project focuses on the practical large scale implementation of solar energy technologies in combination with new build and retrofit low energy building in the cities of Copenhagen, with its city part Valby, in Denmark and Salzburg in Austria. This book aims to influence decision makers in European cities towards a similar approach to the Green Solar Cities project, in close cooperation with leading building component suppliers, energy companies and engaged builders also working with local city officials. This book will benefit those in a situation where many cities aim at a "Smart City" development, but without clear policies of how to achieve that in practice. In Denmark there are similar policies, with an overall aim to be CO2 neutral by year 2025 in the city of Copenhagen. However, there is still a lack of understanding concerning, how solar energy as the world’s number one energy source can play a major role here and how this can be combined with energy efficiency policies, use of district heating and combined heat and power. The general aim is to introduce the international "Active House" standard and work on "Active Roofs" of the future. The connection between solar energy and low energy building and energy renovation is aimed to be ensured by help of the "Active House" standard which has been developed in cooperation with a number of leading building component manufacturers in Europe.

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Energy for Sustainability is the first undergraduate textbook on renewable energy and energy efficiency with a unique focus on the community scale. Written by two of the foremost experts in the field, it is a pedagogically complete treatment of energy sources and uses. It examines the full range of issues—from generating technologies to land use planning—in making the transition to sustainable energy. The book begins by providing a historical perspective on energy use by human civilizations and then covers energy fundamentals and trends; buildings and energy; sustainable electricity; sustainable transportation and land use; and energy policy and planning. Included in these topical areas are in-depth discussions of all of the most promising sources of renewable energy, including solar photovoltaic systems, wind turbines, and biofuels. In addition, the authors offer a thorough presentation of “green” building design, the impact of land use and transportation patterns on energy use, and the policies needed to transform energy markets at the local, state, and national levels. Throughout, the authors first provide the necessary theory and then demonstrate how it can be applied, utilizing cutting-edge practices and technologies, and the most current available data. Since the dawn of the industrial age, the explosive growth in economic productivity has been fueled by oil, coal, and natural gas. World energy use nearly doubled between 1975 and 2005. China’s energy use has been doubling every decade. The implications for the environment are staggering. One way or another, our reliance on fossil fuels will have to end. Energy for Sustainability evaluates the alternatives and helps students understand how, with good planning and policy decisions, renewable energy and efficiency can support world demands at costs we can afford—economically, environmentally, and socially.

EBOOK SYNOPSIS:

This edited book presents the results of the 5th Workshop on Real-world Wireless Sensor Networks (REALWSN). The purpose of this workshop was to bring together researchers and practitioners working in the area of sensor networks, with focus on real-world experiments or deployments of wireless sensor networks. Included were, nonetheless, emerging forms of sensing such as those that leverage smart phones, Internet of Things, RFIDs, and robots. Indeed, when working with real-world experiments or deployments, many new or unforeseen issues may arise: the network environment may be composed of a variety of different technologies, leading to very heterogeneous network structures; software development for large scale networks poses new types of problems; the performance of prototype networks may differ significantly from the deployed system; whereas actual sensor network deployments may need a complex combination of autonomous and manual configuration. Furthermore, results obtained through simulation are typically not directly applicable to operational networks; it is therefore imperative for the community to produce results from experimental research. The workshop collected the state of the art in emerging and current research trends dealing with Real-world Wireless Sensor Networks, with the aim of representing a stepping stone for future research in this field.
