This book presents Digital Twin in clear and accessible terms, showing how it can be used to improve indoor spaces such as homes, offices, and other occupied environments. It explains how DT can support healthier, more comfortable, and more energy-efficient indoor conditions through intelligent monitoring, analysis, and control. The book provides a practical, step-by-step guide to developing and using DT systems to manage key indoor environmental factors, including air quality, temperature, lighting, and related conditions that affect human well-being and building performance. It also addresses common challenges associated with adopting this technology and offers practical ways to overcome them. A unique strength of this book is that it conceptualises and develops a holistic framework for implementing Digital Twin for IEQ management, tailored specifically to the contextual realities of developing countries. By doing so, the book moves beyond general discussion and offers a relevant and actionable pathway for application. Overall, it equips academics, professionals, decision-makers, and interested readers with the knowledge needed to adopt and benefit from DT technology in indoor environmental quality management.
