Indoor Air
• Potential significant contributor to environmental risk.
• Component of green building design.
• Movement of air in an indoor environment:
-design of ventilation systems
-Natural ventilation systems
• Natural ventilation systems are best used in mild or moderate climates with minimal heating or cooling demands. Also in locations with minimal pollution. System capitalize on wind and thermally
generated pressures.
• Modern systems include heat exchangers to transfer energy in exhaust air to inlet air minimizing cooling and heating costs.

Indoor Air Pollution
Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.
