US Science Lab Monitors Indoor Air-quality


Doug Errett’s AP Environmental Science class conducted indoor air-quality monitoring to evaluate air exchange rates in classrooms across campus. Average carbon dioxide (CO2) concentrations were collected in classrooms and compared with outdoor ambient CO2 levels to calculate the approximate rate of air changes per hour (ACH).  In all classrooms, ACH rates were well above the minimum recommended rate of 4 changes per hour, and most were above the “excellent” rating of 6 changes per hour.  #STEMatSTA #LifeAtStAlbans
