Claim 0:
1. A system, comprising:
an air quality monitoring device installed in a monitored area of a building, the air quality monitoring device having a set of one or more sensors that includes an air quality sensor that measures an air contaminant level, the air quality monitoring device installed at a monitored location;
a database configured to store an air exchange rate function and a ventilation performance indicator function;
one or more servers configured to receive a time based series of air quality sensor measurements generated in the air quality monitoring device based on measurements by the air quality sensor of the air contaminant level, wherein for each air quality sensor measurement value received as part of the time based series of air quality sensor measurements, the one or more servers generate an updated air exchange rate value using the air exchange rate function retrieved from the database to produce a time based series of air exchange rate indication, wherein for each updated air exchange rate value generated as part of the time based series of air exchange rate indication, the one or more servers generate an updated ventilation performance indicator value using the ventilation performance indication function retrieved from the database to produce a time based series of ventilation performance indication that assesses the performance of Heating, Ventilation and Air Conditioning (HVAC) equipment in reducing the air contaminant level, the one or more servers further configured to generate a control action based on analysis of the time based series of ventilation performance indication; and
an actuator configured to control an operation of the HVAC equipment to automatically adjust an amount of air ventilation produced by the HVAC equipment in the monitored area in the building, the actuator configured to receive control information based on the control action generated by the one or more servers and to increase the air ventilation produced by the HVAC equipment to reduce the air contaminant level in the monitored area in the building.
