Testing of ventilation systems in forced warm air combustion heated houses.

This research project was performed to gather field experience with houses that had ventilation systems that were expected to be able to meet the CSA F326 Residential Mechanical Ventilation Systems Standard.

The study focused on houses that had central forced warm air heating systems along with central ventilation systems. Two of the houses had air to air heat exchangers, and two had central exhaust fans. The four houses were built between 1983 and 1986.
