The objectives of this field study were to determine if there is a correlation between measured airtightness and ventilation, as well as indoor air quality, and to investigate the main factors which determine indoor humidity levels in the fall and winter. This information is required to determine if there is a range of building airtightness, within which there are no indoor air quality or high humidity problems. Test results of measurements of source strength of various indoor air pollutants in 30 houses in Quebec are presented and compared with similar data obtained from houses in Ontario. With this information, the minimum ventilation required to keep the levels of the various pollutants within acceptable levels can be estimated. Additional observations were also made in eight of these houses to study the effects of living habits and of various ventilation systems on the quality of indoor air and on indoor air humidity levels, and to estimate the actual ventilation rates under various operating conditions. The AQ1 model was used to predict the natural ventilation rate in several houses. The findings indicate that the correlation between measured airtightness and natural ventilation (and indoor air quality) must take into account many factors including the use of combustion equipment, building characteristics and living habits. Most houses experience periods of time during which the amount of natural ventilation is low enough that certain air pollutants rise above the maximum recommended levels. The report concludes that the correlation between indoor air quality and measured airtightness is poor, and that leaky houses as well as airtight houses can experience excessive indoor pollution levels. Certain activities of the occupants strongly influence the production of certain air contaminants. The limiting pollutants in the group of houses tested were fairly evenly distributed among the following three contaminants: formaldehyde, respirable solid particles (RSP) and carbon dioxide.
