Based on concerns about indoor air quality and trends
towards tighter envelope construction, there has been
increasing interest in mechanical ventilation of
residential buildings in the United States. This paper
reports on a simulation study of indoor air quality,
ventilation and energy impacts of several mechanical
ventilation approaches in a single-family residential
building. the study focuses on a two-story house in the
northwestern United States and employs the multizone
airflow and contaminant dispersal model CONTAM96. The
contaminants studied include carbon monoxide, carbon
dioxide, nitrogen dioxide, water vapor, finne particles
and a generic volatile organic compound. One-year
simulations were performed for a base case of envelope
infiltration, passive inlet vents with intermittent
mechanical exhaust, outdoor intake to the forced-air
system return balanced by mechanical exhaust, and
continuous exhaust. Results discussed include whole
building air change rates, energy consumption and
