Integrated Sensor Air Quality Control System (ISAQCS)

Heating and cooling use an immense proportion of the nation’s energy consumption. Much of this energy is wasted by venting the air to the outside during normal ventilation procedures. At the same time, such ventilation is necessary to assure high-quality breathable air within modern buildings which are much more airtight than those constructed decades ago. Ideally, a building’s air would be recirculated and kept at the proper temperature and only ventilated when the quality of the air reached a minimum level.

For this purpose, IEM has developed the Integrated Sensor Air Quality Control System (ISAQCS); ISAQCS tracks the air quality in various locations using easily installed sensors which wirelessly update the central controller. The central controller can then direct the operation of furnaces, fans, dampers, and air conditioning units. Depending on the precise sensors installed in the sensor units, the air quality can be assessed based on CO2 levels (required by government standards), particulates, or various other chemicals such as formaldehyde or other VOCs. Energy savings of up to 50% have been documented with demand-controlled ventilation systems of this nature.
