Ventilation is the intentional introduction of outside air into a space. Ventilation is primarily used to control indoor air quality by diluting or displacing indoor pollutants. It can also serve thermal comfort, satisfaction with other aspects of the indoor environment, or other purposes by controlling indoor temperature, humidity, and air movement.
The invention of the boiler and chiller made it technically feasible to control the overall climate control of a room. Made technically feasible. Regardless of outdoor conditions, building structure, or use.
As Le Corbusier predicted in the 1930s, buildings became of the same type, hermetically sealed and controlled to a constant temperature in all climates (Mahdavi and Kumar, 1996). This energy-intensive solution is supported by the belief that maintaining constant conditions provides comfort and satisfaction.
However, by applying this approach, the building industry has often failed to meet the comfort needs of occupants. According to various surveys, as many as 43% of occupants in the West are dissatisfied with heating, ventilation, and air conditioning (HVAC), and 56-89% of government employees view HVAC as a problem (Lomonaco and Miller, 1996; DiLouie, 2002). This is because the cost of salaries is 8 to 13 times the cost of operating a building.
Ensuring optimal ventilation performance is an important part of building design. This authoritative work, prepared by renowned European and U.S. experts and published in collaboration with the International Energy Agency’s Air Infiltration and Ventilation Center (AIVC), organizes, categorizes, and evaluates information on advances in the key areas of building ventilation that are relevant to all types of buildings.
Complexities in airflow behavior, climatic influences, occupancy patterns, and pollutant emission characteristics make selecting the most appropriate ventilation strategy particularly challenging. Recognizing this complexity, the editors have brought together their expertise on each of the key issues. From components to computer tools, this book provides detailed information on design, analysis, and performance, making it an important and comprehensive publication in this field.
This book will be an invaluable reference for building services industry professionals, architects, researchers (including graduate students) studying building services engineering and HVAC, and anyone involved in energy-efficient building design.
