Abstract

Demand ventilation protocols can address the issue of sensor failure while still providing desirable levels of energy conservation. An occupancy indicator such as a sensor can be monitored. If the sensor reading is determined to be incorrect, unexpected or otherwise erroneous, the ventilation system can provide an amount of fresh air sufficient for adequate ventilation without over-ventilating the building.
