The aim of this book is to deepen the knowledge of dynamic evolution of professional practices (recomposition of knowledge and know-how, inter-relations, strategic positioning) taking place at the time of the injunction to energy efficiency in the design field, construction and management of real estate. From their experience feedback, the challenge of this book is to question the logic of innovation, to enlighten the dynamic learning and renewal of professional skills.

The recast of the Energy Performance of Buildings Directive (EPBD) was adopted by the European Parliament and the Council of the European Union on 19 May 2010. For new buildings, the recast fixes 2020 as the deadline for all new buildings to be “nearly zero energy” (and even sooner for public buildings – by the end of 2018). This book gives practitioner an important tool to tackle the challenges of building refurbishment towards nearly zero energy. This book is welcome at this time and sets the scene for professionals whether practitioners or researchers to learn more about how we can make whether old or new buildings more efficient and effective in terms of energy performance.
This book analyzes the trends and technologies of green and energy efficient building, identifying strategies for implementing energy savings and enabling the use of renewable resources in residential, commercial, healthcare and educational building sectors. The authors focus on best practices in temperate climates, providing in-depth coverage of urban heat island, climate change and fuel poverty mitigation through architectural optimization, leveraging renewable energy sources and utilization of cutting-edge cooling materials. Pragmatic emphasis is placed on improving the energy performance of existing building stock to meet short and long term objectives of climate and energy conservation strategies. Engineers, architects, designers, students, policy makers and efficiency professionals will all gain valuable insights and ideas from this practical handbook to greening the built environment.
A reduction in the energy demand of buildings can make a major contribution to achieving national and international carbon reduction goals, in addition to addressing the interlinked issues of sustainable development, fuel poverty and fuel security. Despite improvements in thermal efficiency, the energy demand of buildings stubbornly remains unchanged, or is only declining slowly, due to the challenges posed by growing populations, the expectations of larger, more comfortable and better equipped living spaces, and an expanding commercial sector. Building Futures offers an interdisciplinary approach to explore this lack of progress, combining technical and social insights into the challenges of designing, constructing and operating new low energy buildings, as well as improving the existing, inefficient, building stock. The twin roles of energy efficiency, which is predominantly concerned with technological solutions, and energy conservation which involves changing peoples’ behaviour, are both explored. The book includes a broad geographical range and scale of case studies from the UK, Europe and further afield, including Passivhaus in Germany and the UK, Dongtan Eco City in China and retrofit houses in Denmark. This book is a valuable resource for students and academics of environmental science and energy-based subjects as well as construction and building management professionals.
Buildings are one of the main causes of the emission of greenhouse gases in the world. Europe alone is responsible for more than 30% of emissions, or about 900 million tons of CO2 per year. Heating and air conditioning are the main cause of greenhouse gas emissions in buildings. Most buildings currently in use were built with poor energy efficiency criteria or, depending on the country and the date of construction, none at all. Therefore, regardless of whether construction regulations are becoming stricter, the real challenge nowadays is the energy rehabilitation of existing buildings. It is currently a priority to reduce (or, ideally, eliminate) the waste of energy in buildings and, at the same time, supply the necessary energy through renewable sources. The first can be achieved by improving the architectural design, construction methods, and materials used, as well as the efficiency of the facilities and systems; the second can be achieved through the integration of renewable energy (wind, solar, geothermal, etc.) in buildings. In any case, regardless of whether the energy used is renewable or not, the efficiency must always be taken into account. The most profitable and clean energy is that which is not consumed.
This book presents interdisciplinary approaches to help buildings, electrical energy networks and their users contribute to the energy and societal transition. Smart Grids and Buildings for Energy and Societal Transition examines the technologies, uses and imaginaries involved in implementing smart buildings and smart grids. Production and consumption forecasts, modeling of stakeholder involvement and self-consumption within a renewable energy community exploiting blockchain technology are examples developed with a view to fostering the emergence of smart grids. The potential of smart buildings, taking into account user comfort while increasing energy efficiency, is identified. Full-scale demonstrators are used to test the proposed solutions, and to ensure that users take full advantage of the potential for electrical flexibility.
Measuring and reducing energy consumption constitutes a crucial concern in public policies aimed at mitigating global warming. The real estate sector faces the challenge of enhancing building efficiency, where insights from experts play a pivotal role in the evaluation process. This research employs a machine learning approach to analyze expert opinions, seeking to extract the key determinants influencing potential residential building efficiency and establishing an efficient prediction framework. The study leverages open Energy Performance Certificate databases from two countries with distinct latitudes, namely the UK and Italy, to investigate whether enhancing energy efficiency necessitates different intervention approaches. The findings reveal the existence of non-linear relationships between efficiency and building characteristics, which cannot be captured by conventional linear modeling frameworks. By offering insights into the determinants of residential building efficiency, this study provides guidance to policymakers and stakeholders in formulating effective and sustainable strategies for energy efficiency improvement.
Energy autonomy is an emerging concept that is, as yet, poorly identified in France. It can mean taking ownership of certain issues related to energy, its production, or, indeed, becoming self-sufficient, and it can apply equally to individuals, communities and buildings. While there are numerous new developments – renewable energies, smart grids and self-consumption – it is becoming difficult to know what this idea of “autonomy” covers, just as it is difficult to define “independence” and “self-sufficiency”, which are often associated with it. However, these three concepts are key to thinking about the energy system and deciding its future. Covering distinct ideas, they are often reduced to economic and productive factors. This ambiguity in their meanings is responsible for the misunderstandings, delusions and obstacles that hamper the implementation of the energy transition. This book deconstructs the common idea of autonomy in favor of a set of more operational concepts. It demonstrates that these ideas are not interchangeable but rather represent practical and constructive tools for action. The world of energy is changing, and therefore we must rethink energy autonomy.
The energy sector is undergoing unprecedented change. Twenty years ago, the main concern was having enough oil and gas, whereas today, political leaders are faced with the need to reduce the CO2 emissions produced by still-dominant fossil fuels, without being able to totally rely on renewable energies, which are intermittent and whose share in energy production remains low. Geopolitics and Energy Transition 2 examines the energy sector and the state of energy transition continent by continent. North America is rich in resources, while the situation is mixed in South America. Europe advocates transition but remains dependent on imported fossil fuels. The CIS has enormous resources at its disposal and uses them as political weapons. Access to energy is a priority for Africa. Asia is faced with growing energy needs and pollution, which should accelerate energy transition. The Middle East, a champion of hydrocarbons, is launching into solar energy.
