QUANTIFYING THE EFFECT OF INFILTRATION ON CONTAMINANT CONCENTRATIONS FOR DIFFERENT EMISSION SCENARIOS

I. A. Macdonald, J. T. Reardon

Abstract: Current building codes and construction practices are delivering increasingly airtight residential buildings. This is beneficial in terms of reducing energy demand but is increasingly linked to adverse health effects. This paper examines the natural supply of outside air to Quebec City dwellings and examines the concentration of contaminants for various occupancy scenarios. Using local weather data and measured envelope leakage data the requirement for additional mechanical ventilation to meet existing standards is assessed. The contaminant concentrations are compared to a mechanical system delivering the fresh air at rates prescribed in the model national building code. Additionally the energy implications of excessive infiltration and additional mechanical ventilation are quantified.
