Informationen zum Autor Prof. Dr. Ursula Eicker!University of Applied Sciences! Stuttgart! GermanyUrsula is Professor of Building Physics at the HfT (Stuttgart University of Applied Sciences)! and teaches a Master course in sustainable energy competence. She manages the advanced technical college's institute for applied research and the centre for applied research (sustainable energy technology). Ursula is a member of EnerBuild RTD (Research & Technological Development) and has delivered presentations on the research and development of mechanical heating and cooling on their behalf. She had material on desiccant cooling technology published in the proceedings of the ISE Solar World Congress in 2003! and her previous book (Solar Technologies for Buildings! published by Wiley) is a recommended title on the Green Building engineering course at Canada's leading research-intensive university! Queens.She recently won the opportunity to manage and coordinate POLYCITY! a project worth £47!500 that focuses on developing innovative solutions for using renewable energies within urban districts in three European countries. Klappentext Energy efficient buildings supplied by renewable energy sources are the key to reduce today´s dependency on fossil fuels and associated CO2 emissions. To achieve efficiency goals! buildings need to use passive and low-energy resources such as solar gains! daylight! natural ventilation or geothermal heat exchange as intelligently as possible in combination with insulation and storage mass concepts. Dense urban areas influence the energy performance of individual buildings and provide further challenges for passive solar energy use.Exploiting solar and geothermal resources to cover the building energy demand! this reference provides detailed insight into the design and physics of energy efficient buildings and renewable supply systems. 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 practical applications! enabling the reader to gain an in-depth knowledge of today´s new energy systems and building concepts.Key Features:* Includes general introductory sections for each technology with market potential and applications* Considers a broad range of alternative renewable energy supplies relevant to the building sector! such as solar photovoltaics! solar thermal and low depth geothermal energy* Provides detailed physical models of all technologies and example calculations* Supports understanding with coverage of the fundamentals of meteorological modelling* Addresses an increasingly important component of energy coursesThis invaluable reference has been developed for mechanical and building services engineers! civil engineers! building physicists! electrical engineers! researchers and lecturers. It will also be of interest to architects with an interest in energy efficiency and graduate and senior undergraduate students in engineering! building science and building physics. Zusammenfassung A modern and unique perspective on solar and geothermal technologies for heating and cooling buildingsThis book will have a broad appeal reaching practising engineers in the industry as well as students. With introductory sections for each technology described! material includes chapters on: geothermal energy use for the heating and cooling of buildings; a chapter on electrically driven heat pumps/chillers; material on night radiative cooling! photovoltaic thermal collectors! temperature modelling and thin film photovoltaic modelling.* Includes general introductory sections for each technology with market potential and applications* Covers an increasingly important component of energy courses* Considers a broad range of alternative renewable energy supplies relevant to the building sector! such as ...
