Childhood Asthma and Chicago’s Silent Killer

Childhood asthma has become the most chronic childhood disease in the industrialized world largely due to indoor environmental factors and air quality in particular. C02 emissions and PM 2.5 represent significant drivers.

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 delivers a continuous stream of fresh filtered air through 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. Further, Ellis Passivhaus uses specialized drywall and bath tile that render commonly occurring volatile organic compounds inert.

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.”
