St. Albans Church: Enabled a new ERV system, which was failing to deliver adequate heat or cooling, to be effective at half its available speed

St. Alban’s Church, A 150 year - old stone building in Ottawa, Canada is the oldest church in the city. Recent renovations to the interior included a energy efficient ERV system and new ductwork to increase the indoor comfort and improve the ventilation in this historic landmark. Once installed, the system was tested with disappointing results. The ERV wasn’t drawing in or blowing out a sufficient amount of air to do its matter how high they cranked it.
