Energy Efficient Buildings with Solar and Geothermal Resources

by Ursula Eicker

Overview

A modern and unique perspective on solar and geothermal technologies for heating and cooling buildings

This 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 geothermal energy with heat pump
• With a special focus on solar cooling, provides detailed physical models of all technologies and example calculations
• Unique in covering the fundamentals of meteorological modelling

Dr. Ursula Eicker, University of Applied Sciences, Stuttgart, Germany
Ursula 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.
