Indoor Air Quality

According to the World Health Organization (WHO), indoor air pollution associated with solid fuel use kills approximately 1.6 million people each year and represented 2.7 percent of the global burden of disease (in disability-adjusted life years, or DALYs). Hence, poor indoor air quality is the second-biggest environmental contributor to morbidity and mortality, behind unsafe water and poor sanitation. In several regions of the world, people spend most of their time indoors. The building design and ventilation in most of the cases influence the indoor air quality concentrations. Due to high population density and land scarcity, and as an effort to conserve energy, building designs are compact, with lower rates of ventilation in some places. While some buildings have natural ventilation, others have mechanical ventilation. Also, ...
