Why Use Air to Air Heat Exchangers?
Why Bother with mechanical ventilation for Homes and Commercial Buildings? National codes and building standard require a prescribed amount of fresh outdoor air. More fresh outdoor air generally means less indoor air pollution (IAP) and better Indoor Air Quality (IAQ). Indoor air pollution (IAP) is ranked by the Environmental Protection Agency (EPA) among the top five environmental risks to human health. The World Health Organization estimates that nearly one in every six commercial buildings in the United States suffers from sick-building syndrome and that occupants of another one in twelve suffer from building-related illnesses. Indoor air quality (IAQ) problems cost American business $10 billion per year through lowered productivity, absenteeism, and medical costs. The World Health Organization reports that one billion people are regularly exposed to dangerous levels of indoor air pollution, whether at home, at work or when traveling by mass transit.
