This book includes five chapters that explore the topic of indoor air quality from several perspectives. Chapter One investigates the efficiency of a solar air heater system. Chapter Two examines the effect of indoor air pollution in child populations in educational settings. Chapter Three studies the impact of numerical parameters on heat ventilation in a box prototype. Chapter Four includes simulations of airflow related to a room containing a sitting person and a computer to determine ventilation system performance. Lastly, Chapter Five analyzes airflow in spaces equipped with a vertical confluent jets ventilation system.
