The document discusses indoor air quality and ventilation systems. It notes that modern homes are built to be more energy efficient but also tighter, which can trap pollutants indoors. Properly installed mechanical ventilation, such as heat recovery ventilators, is presented as the best way to ventilate all rooms while minimizing energy loss and capturing pollutants. Natural ventilation alone is not reliable enough to ensure good indoor air quality in tight homes.

Flood Cleanup: Avoiding Indoor Air Quality Problems - Fact Sheet via EPADry Wizard Restoration
During a flood cleanup, the indoor air quality in your home or office may appear to be the least of your problems. However, failure to remove contaminated materials and to reduce moisture and humidity can present serious longterm health risks. Standing water and wet materials are a breeding ground for microorganisms, such as viruses, bacteria, and mold. They can cause disease, trigger allergic reactions, and continue to damage materials long after the flood.

This presentation provides an overview of different types of mechanical ventilation systems and discusses why heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems are characterized by a high level of energy efficiency and as an effective means for improving indoor air quality.

Zehnder America a Fresh Look at Indoor Air QualityZehnder America
Home should be a place where you can breathe easy, but today that might not be the case. Indoor air pollution can be worse than outdoor pollution, and people spend about 87% of their time indoors, an average of 69% at home.
Environmental Protection Agency studies found pollution indoors could be two to five times higher than outdoor levels, and in rare cases up to 100 times worse. In this special report sponsored by Zehnder America Inc., we’ll outline causes of indoor air pollution and discuss solutions available to create a safe and comfortable
indoor environment.
Ventilation is necessary in modern controlled poultry houses to provide fresh air into the house and to expel noxious gasses from the house to keep the environment fresh and birds healthy.
There are different types of ventilation depends on the weather like minimum ventilation in cold weather, transitional ventilation in optimum weather and tunnel ventilation in extreme weather.
At present, air pollution indoors is listed by the EPA as the 4th largest environmental threat to people in America. As a heating and cooling system is in operation, airborne contaminants are usually being drawn into a duct system. Over a span of time, those dangerous pollutants eventually will build up inside air ducts. http://www.airtekma.com/duct-cleaning/benefits-air-duct-cleaning/

41. What is a “tight” house? “ Home Building Envelope Air Leakage Area. The median ACH50 (air changes per hour at 50 pascals) for the homes in this study was 4.8 air changes per hour, which compares to a median of 5.2 air changes per hour for a group of homes built since 1992 and 8.6 air changes per hour for a group of homes built before 1987 . New Californian homes are generally being built tighter, but not exceptionally tight, like those found in colder climate regions.” Pre 1987 = 8.6 ACH50 Since 1992 = 5.2 ACH50 2003-07 = 4.8 ACH50 (Calif. Study Houses) In Maine, If an energy auditor tests your home and it is at or above 3.5 ACH50 you will be told that you have plenty of natural ventilation and that you do not need any additional.
