Occupancy scenario in the house
This study evaluates the indoor air quality in a small single-family house by using computational fluid dynamics (CFD) and a variety of mixing models. CO2, CO, NO2, formaldehyde (HCHO), and vapor are tracked throughout the house to determine the concentration levels, occupational dosing, and personal exposure for a family of two adults and two children. Variations in metabolic activity, smoking, gas stove cooking, and showering make exposure very dependent on the individual’s location in the house due to pollutant migration.
