Abstract

The purpose of this study is to evaluate the relevance of household characteristics on exposure time to CO2 in houses with balanced ventilation. Statistical tests were conducted to measure the significance of household differences on time indoors. Household scenarios and ventilation scenarios were constructed to determine the level of CO2 indoors. The production of CO2 was calculated with the metabolic rate per age of the members of the household. Households are exposed to levels of CO2 higher than 1000 ppm in houses with low infiltration rate. In practice, the air flow does not comply with the requirements because of the use of the system and for lack of maintenance. High levels of CO2 (over 5000 ppm) were not shown to be a risk in this study, but exposure to levels of CO2 between 1000 and 2000 is used as an indicator of other pollutants indoors.
