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.

This book presents a methodology for the design, construction, monitoring, optimization, and post-occupancy evaluation of net-zero and positive-energy communities based on the experiences gained in the EU Horizon 2020 ZERO-PLUS project. It describes the steps, tools, and methods developed during the project, providing practical information for the energy and construction sector that will be of interest to students, engineers, architects, developers, and professionals working around high performance architecture and sustainable communities. Through the ZERO-PLUS project, a consortium of 32 partners from eight countries, including academic institutions, technology providers, architects, and construction companies, designed four communities covering completely different geo-climatic regions, construction practices, and cultural backgrounds in Cyprus, Italy, France, and the UK. The communities were designed, optimized, constructed, monitored, handed over to tenants, post-occupancy evaluated, and troubleshooted through a system of continuous collaboration and data acquisition. This book presents these case studies and shows how the project targets of reducing electricity consumption below 20 kWh/m2/y, increasing electricity production from Renewable Energy Systems to over 50 kWh/m2/y, and at cheaper costs when compared to current zero-energy buildings were reached and surpassed. These cases demonstrate that a holistic and interactive approach to design and construction can bring communities a high standard of sustainability. The key features of the book include: • Practical guidance drawn from the interdisciplinary, international, and remote cooperation between experts from academia and industry across the construction sector. • A survey of the state-of-the-art on net-zero and positive-energy communities, including the experience and the lessons learned from previous projects and from the ZERO-PLUS project. • Descriptions of novel emerging renewable energy technologies, integrated into real case study communities to achieve the energy generation target of the communities. • A comprehensive set of approaches, tools, guidelines, best practices, challenges, and lessons learned from the five-year ZERO-PLUS project and the completion of four residential case studies to inform the reader of how to achieve affordable net-zero energy communities. • Four typologies of residential communities located in different climatic conditions are presented, touching on the critical aspects of the design, construction, monitoring, and occupancy phase • A discussion of future trends for developing communities that are more liveable, accessible, and sustainable and which can comply with new energy policies in a way that is affordable for the owners and residents.

Reducing the impact of climate change is one of the main challenges of today’s society. As such, it is necessary to reduce the high energy consumption that comes with constructing and using buildings. Current energy policies are promoting decarbonization of the built environment using the nearly zero-energy building’s concept. This book presents information on nearly zero-energy buildings, including materials, design, and new approaches.

This book presents novel findings concerning the systems, materials and processes used in solar energy conversion in communities. It begins with the core resource – solar radiation – and discusses the restrictions on the wide-scale implementation of conversion systems imposed by the built environment, as well as potential solutions. The book also describes efficient solar energy conversion in detail, focusing on heat and electricity production in communities and water reuse. Lastly, it analyzes the concept of sustainable communities, presenting examples from around the globe, along with novel approaches to improving their feasibility and affordability. Though chiefly intended for professionals working in the field of sustainability at the community level, the book will also be of interest to researchers, academics and doctoral students.

This book focuses on solar energy conversion systems that can be implemented in the built environment, at building or at community level. The quest for developing a sustainable built environment asks for specific solutions to provide clean energy based on renewable sources, and solar energy is considered one of the cleanest available energy on Earth. The specific issues raised by the implementation location are discussed, including the climatic profile distorted by the buildings, the available surface on the buildings for implementation, etc. This book also discusses the seasonal and diurnal variability of the solar energy resource in parallel with the variability of the electrical and thermal energy demand in the built environment (particularly focusing on the residential buildings). Solutions are proposed to match these variabilities, including the development of energy mixes with other renewables (e.g. geothermal or biomass, for thermal energy production). Specific solutions, including case studies of systems implemented on buildings all over the world, are presented and analyzed for electrical and for thermal energy production and the main differences in the systems design are outlined. The conversion efficiency (thus the output) and the main causes of energy losses are considered in both cases. The architectural constraints are additionally considered and novel solar energy convertors with different shapes and colors are presented and discussed. The durability of the solar energy conversion systems is analyzed considering the specific issues that occur when these systems are implemented in the built environment; based on practical examples, general conclusions are formulated and specific aspects are discussed in relation to experimental results and literature data. With renewables implemented in the built environment likely to expand in the near future, this book represents welcome and timely material for all professionals and researchers that are aiming to provide efficient and feasible solutions for the sustainable built environment.
