This guideline defines ventilation and then natural ventilation. It explores the design requirements for natural ventilation in the context of infection control, describing the basic principles of design, construction, operation and maintenance for an effective natural ventilation system to control infection in health-care settings.

Ventilation is an indispensable aspect of our built environment, yet it often operates quietly in the background, unseen and unheard. It is the invisible force that breathes life into our homes, workplaces, and public spaces, influencing our health, comfort, and overall well-being. The quality of the air we breathe indoors profoundly affects our lives, from our ability to concentrate and be productive to our susceptibility to illnesses and allergies. This book delves into the world of ventilation, unveiling its significance, principles, and applications across diverse settings. Whether you are a homeowner seeking to enhance indoor air quality, an architect striving to create sustainable buildings, or an engineer working on cutting-edge ventilation technologies, this book is a comprehensive guide to understanding, implementing, and optimizing ventilation systems. Ventilation is not a static field; it evolves in response to advancing technologies, changing environmental concerns, and the pursuit of healthier, more efficient indoor environments. In each chapter, we explore different facets of ventilation, from its role in mitigating the spread of respiratory diseases like COVID-19 to its pivotal role in green building practices aimed at reducing our carbon footprint. As we navigate the intricate world of ventilation, we emphasize best practices, emerging trends, and innovative solutions that are shaping the future of indoor environments. Whether you are seeking practical advice for improving ventilation in your home, insights into sustainable building design, or a glimpse into the technologies that will revolutionize the field, this book equips you with the knowledge to make informed decisions and contribute to creating spaces that prioritize health, comfort, and environmental responsibility. In our exploration of ventilation, we aim to illuminate the importance of this often-overlooked aspect of our daily lives. By understanding its principles and embracing best practices, we can breathe easier, work more productively, and live healthier lives in the spaces we call home, work, and play. We invite you to embark on this journey through the world of ventilation, and we hope you find the insights and knowledge within these pages both enlightening and empowering. Sincerely, Charles nehme

This book discusses energy recovery technology, a green innovation that can be used in buildings. This technology reduces energy consumption in buildings and provides energy savings to conventional mechanical ventilation systems. Divided into eight chapters, the book provides in-depth technical information, state-of-the-art research, and latest developments in the energy recovery technology field. Case-studies describe worldwide applications of energy recovery technology and its integrated system for building services. This book will be used as a general and technical reference book for students, engineers, professionals, practitioners, scientists, and researchers seeking to reduce energy consumption of buildings in various climatic conditions. Presents an overview of energy consumption scenarios in buildings and the needs for energy-efficient technologies at regional and global levels; Explains models and methods of energy recovery technology performance evaluation; Inspires further research into energy recovery technology for building applications.

Natural ventilation in buildings, generally belongings to bio climatic design, can provide a comfortable indoor climate and major possibilities for energy saving and reducing energy consumption due to mechanical ventilation and air conditioning systems. Natural ventilation is the most efficient passive cooling systems, which was also used in traditional, historic architecture to improve thermal efficiency and indoor building comfort. Many historic buildings in Italy were split between summer and winter apartments. the summer apartment was located on the ground floor and frescoed. Its cool indoor climate was due to the presence of surrounding gardens and to the high thermal inertia of the ground and wall. Sometimes these rooms benefited from effective natural air-conditioning systems with air channels, gratings. underground openings and rooms and basins for rain water storage. Some architectural structures inside historical buildings are often interpreted as cooling systems. The problem is the knowledge about the real functioning of these systems during the past and at the present.
