The indoor environment in houses has a profound impact on occupant’s health and comfort. Research by Canada Mortgage and Housing Corporation (CMHC), Health Canada, and Environment Canada have shown that attached garages can transfer automotive generated pollutants to the indoor air of houses, resulting in compromised indoor air quality.The amount of contaminant transfer and the effect of proposed solutions are highly variable depending on the airtightness performance of the house, garage, and their interface. The current research provides a basis for understanding the importance of attached garages as a source for indoor air quality problems, and identifies appropriate strategies for managing contaminant transfer in new and existing homes.
