Chicago’s Silent Killer

Among major US cities Chicago, Chicago gets an “F” for air quality according to American Lung Association, sentiments echoed by the EPA as well, citing high concentrations of “PM 2.5” (particulate matter > 2.5 microns.) This affects the health of over 5 million people in the greater regional area. Ellis Passivhaus incorporates a Zehnder whole house ERV (energy recovery ventilator) that removes 90% of particulate matter greater than 1.0 microns and 75% of particulate matter < 1.0 microns. It runs 24/7 at 84% efficiency and uses < 2 kWh of energy per day.

We spend 90% of our time indoors.

Indoor Air Quality is 5 to 10 x worse than outdoor air quality. PM 2.5 can’t be seen and results primarily from combustion.

Chicagoans spend 90% of their time indoors were air quality is > 5x worse than outdoor air quality.     
Among major US cities, Chicago with others rank in the highest category of PM 2.5 concentration.  PM 2.5 (“particulate matter 2.5 microns”) has been linked to morbidity and cannot be seen by the naked eye.  PM 2.5 primarily results from combustion.  
Every Passivhaus Institut Certified Building requires a whole-house ERV to provide “continuous balanced mechanical ventilation with energy recovery.”
Ellis Passivhaus uses a Zehnder ERV that removes 90% of particulate matter greater the 1.0 microns and 75% that is < 1.0 microns.  It runs 24/7 at 84% efficiency and uses < 2 kWh per day of electricity.
