Water Efficiency in Buildings – Theory and Practice

A roadmap to water efficiency in buildings. provides comprehensive and up-to-date information on water efficiency in buildings all in one book includes both research and showcases of innovations, systems and approaches for water efficiency in buildings collates learning and evidence that can be used to understand and apply solutions for water efficiency in buildings presents a multi-disciplinary viewpoint, from architecture to environmental science and socio-psychology demonstrates how to engage stakeholders in a systems approach to tackling the challenges The book is presented in five sections: Policy, People, Building Design and Planning, Alternative Water Technologies and, Practical Examples and Case Studies. The final section of the book presents new and current practise as well as lessons learnt from case examples on the use of water saving technologies and user engagement. Current evidence is vital for effective policy making. The dynamic nature of issues pertaining to water resource management creates a higher need for robust and reliable data and research information that can inform or guide policy and regulatory decisions. This compendium aims to providea signpost to the knowledge, expertise and evidence that currently exist on the subject of water efficiency in buildings. The research and case studies fall within the water supply and demand spectrum, especially those that focus on process efficiency, resource management, building performance, customer experiences and user participation, sustainable practises, scientific and technological innovation. The benefit and impact of the research is at the local and national level, as well as in the global context.
