Indoor Environmental Quality
Americans spend 90% of their time indoors. It is also reported that pollutant levels can run more than 100 times higher than outdoor levels. Because of this, indoor environmental air quality has to be a top priority for green buildings. Indoor environmental quality does not only involve indoor pollutant control and increased ventilation of spaces, but also includes the overall comfort of the building occupants. Buildings can earn up to 17 credits regarding all of these aspects.
