A look at using energy-recovery ventilation and ERV Wheels as a means to achieve optimal indoor air quality.
By Randall Steele
According to the Environmental Protection Agency (EPA), studies on human exposure to air pollutants indicate that indoor levels of pollutants may be two to five times – and occasionally more than 100 times – higher than outdoor levels. Considering Americans spend approximately 90% of their time indoors, the EPA and its Science Advisory Board consistently rank indoor air pollution among the top five environmental health risks to the public. In fact, the EPA has estimated that nearly one-half of all illnesses are related to indoor air pollution.
It almost goes without saying that fresh air is a requirement for a healthy environment. Without a continuous supply of oxygen, the emissions from building materials, occupants and indoor activities become concentrated in the air being breathed. Constant exposure to indoor activities become concentrated in the air being breathed. Constant exposure to indoor contaminants such as airborne viruses, radon, formaldehyde and a host of other pollutants can impact occupants’ health and productivity, becoming major liabilities for building owners and managers.
The most common tenant and occupant complaints, related to indoor air quality include asthma and allergies, humidity, stuffiness, tiredness, low productivity, low morale, and dry skin and mouth. Fortunately, these liabilities can be easily avoided with proper ventilation. Read full article below.
