Preface

First of all, I highly appreciate the initiative of IntechOpen to publish a book on indoor environmental quality (IEQ ). This domain has attracted a large number of audiences and researchers, as evidenced by the dramatically increasing number of research works in the literature. Even though many books are available in this field, the open access facility of this book is expected to attract a wider readership.

Chapter 1 of this book provides an overview of IEQ, wherein the various constituents of IEQ are briefly explained, followed by research trends and concluding remarks. Chapter 2 presents an exclusive review of indoor air quality (IAQ ), which is a major component of IEQ. Chapter 3 focuses on the monitoring of IAQ in healthy buildings. Chapter 4 deals with the guidelines to ensure the best illumination in indoor spaces. While Chapter 5 presents a practical study of IEQ in healthcare buildings. Chapter 6 deals with acoustic comfort in worship places. The authors of each chapter of this book are renowned experts in the field of IEQ. This book is expected to benefit undergraduate and postgraduate students, researchers, teachers, practitioners, policy makers, and every individual who has a concern for

While presenting this book to an august audience, I gratefully acknowledge the contributions of the authors, the initiative of Ms. Anja Filipovic to launch the book, and the excellent administrative support of Ms. Dolores Kuzelj, all of whom collec-
