One of the world’s major challenges is the transformation of its energy system, which for a short period in human history has been based on fossil fuels. These resources are approaching their end and create serious environmental damages by emissions and long-term waste issues. Renewable energy sources have always been available on Earth and can easily cover the planet´s energy demand. New technologies in solar cell and wind turbine manufacturing, innovative materials and ef ciency strategies support the transition to environmentally friendly energy systems. Especially in urban areas, buildings are major energy consumers.
All together they account for about 40% of nal energy consumption worldwide and are responsible for about one third of overall CO2 emissions. In urban structures, building energy consumption is typically twice as high as the need for transport energy, and the energy-saving potential is large. Up to 20% can be saved in the short term and within the next decades buildings should become climate neutral. In urban areas, solar technologies are the most suitable energy sources, as solar modules and collectors can be easily integrated into buildings. In denser urban structures, often the individual roof and facade surface areas are not suf cient to make each building zero energy.
Here new concepts are required for the design of local supply systems in city quarters with adequate distribution networks and storage capacities. Planners, engineers and researchers need fundamental knowledge to deal with uctuating renewable energy sources, to design adequate storage systems and to integrate the energy systems in highly ef cient buildings. To achieve ef ciency goals, buildings need to use passive and lowenergy resources such as solar gains, daylight, natural ventilation or geothermal heat exchange as intelligently as possible.
This new textbook on energy ef cient buildings with solar and geothermal resources provides detailed insight into the design and physics of energy ef cient buildings. It discusses the theoretical background of solar thermal cooling and heating, of photovoltaics and geothermal energy, and provides information on applications and costs. Many examples help to apply the theory to real praxis applications. The reader as an engineer, physicist, energy planner, researcher, student or informed layman will pro t from the textbook by acquiring in-depth knowledge of today´s new energy systems and building concepts.
This book is based on the knowledge developed within 20 years of research at the Stuttgart University of Applied Sciences on buildings and renewable energy systems. The research centre Sustainable Energy Technologies has been successfully involved in many national and European research and demonstration projects on solar cooling and heating, geothermal energy use, simulation and energy management, zero energy buildings, photovoltaic system technology and many other topics. Without the support of this research group with about 30 scientists, the broad subject range of the book would not have been possible.
I would like to especially thank PhD students and now doctors of philosophy Dilay Kesten and Aysegül Tereci, who produced many results of the rst two chapters of building energy ef ciency in the urban context; PhD student Tobias Schulze who worked on natural ventilation, and Antoine Dalibard and Felix Thumm who developed the compression chiller and photovoltaic thermal collector models; Dr. Dirk Pietruschka, who did many simulations on solar cooling systems; Ruben Pesch for his contribution to geothermal energy analysis and Mariela Cotrado for her comparison of thermal and electric cooling; Eric Duminil for his very nice irradiance maps; and all the other members of our research team, who discussed the physics and applications of solar and geothermal energy use in buildings.
