Condensate Water Reuse Systems: Smart Collection and Reuse Strategies for Sustainable Buildings

Condensate water reuse systems offer a practical, low-risk, and cost-effective opportunity to reduce potable water consumption by 10–30%, particularly in buildings with high cooling loads and humid operating conditions. When properly designed and controlled, these systems can supply cooling towers, irrigation networks, and sanitary flushing systems with minimal treatment and high reliability.

This book was written to bridge the gap between sustainability goals and practical engineering implementation. It focuses on real-world design strategies, system components, smart controls, regulatory considerations, and operational best practices. Rather than promoting theoretical concepts alone, it provides engineers, consultants, facility managers, and decision-makers with actionable guidance on how to design, integrate, and operate condensate water reuse systems safely and effectively.

Whether used as a technical reference, a sustainability roadmap, or a decision-support tool, this book aims to demonstrate how intelligent use of HVAC condensate can contribute meaningfully to water conservation, operational savings, and long-term building resilience.
