Final report: corridor air ventilation system energy use in multi unit residential buildings.

A field test protocol to assess the heating season energy impact of operating corridor ventilation systems was developed and successfully applied to five multi-unit residential buildings (MURBs) in Winnipeg. The protocol was straightforward and inexpensive to apply. The data analyses, done in a spreadsheet computer program, revealed a similar relationship between energy use and operation of the corridor ventilation system for all five MURBs. Operating corridor ventilation systems resulted in increases in heating season energy use equivalent to the energy needed to heat 60 to 90% of the amount of air supplied by the corridor ventilation systems. This increase was considerably more than had been anticipated, indicating that operating corridor ventilation air supply systems does not displace as much infiltration as had been expected.
