Natural ventilation rates through windows in homes

Abstract

Field measurements were conducted with twenty-three sample homes during one year, and analyzed the actual amount of natural ventilation through windows. Indoor CO2 concentrations were more frequently over 1,000 ppm when the outdoor temperature was lower. Daily natural ventilation rates ranged from 30 m3/day to 489273 m3/day. The natural ventilation rates were insufficient in the lower outdoor temperature, because the window was less opened. © 2018 15th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2018.
