BETTER CLASSROOM VENTILATION
BETTER ATTENDANCE MEANS
MORE LEARNING AND
MORE DOLLARS
BETTER STUDENT HEALTH
(1) Mendell et al (2013) "Association of
Classroom Ventilation With Reduced
Illness Absence..."
California Study of 168 Classrooms1
Increasing classroom VRs from the California average (8.5 cfm per
person) to the State standard of 15 cfm would decrease Illness
Absences by 3.4%
(2) Corsi et al (2002) "Carbon Dioxide
Levels and Dynamics in Elementary
Schools..."
Texas Study of 120 Classrooms2
(3) Shendell et al (2004) "Associations
between classroom CO2
concentrations and student
attendance..."
Median CO2 levels were 28% higher than ASHRAE limit
Washington & Idaho Study of 434 Classrooms3
A 1000 PPM increase in CO2 was associated with a 10% - 20%
increase in student absence

School funding often depends on
daily attendance, so better attendance
may often pay for ventilation upgrades.

BETTER VENTILATION
BETTER OCCUPANT PERFORMANCE
BETTER VENTILATION
MEANS
BETTER PERFORMANCE
Harvard Study4
(1) Allen, et al., Associations of Cognitive
Function Scores with Carbon Dioxide,
Ventilation, and Volatile Organic
Compound Exposures..."
On average, a 400 ppm increase in CO2 was associated with
a 21% decrease in cognitive function scores
(2) Shaughnessy, et al., Effects of
Classroom Ventilation Rate
andTemperature on Students’ Test
Scores..."
70-school Study in Southwestern US5
Students’ mean mathematics scores were increased by 0.5% per
2 cfm/person increase in ventilation rate within the range of 2 – 15 cfm
(3) Shaughnessy, et al., "A preliminary
study on the association between
ventilation rates in classrooms and
student performance …"
54-school Study across USA6
Math and Reading scores were 14% higher when VRs were greater
than 10 cfm/student compared to scores when VRs were less than 5
cfm/student

SO, WHY ARE MOST CLASSROOMS
UNDER-VENTILATED?
• Classic Rooftop HVAC Units (RTUs) Only Ventilate
When Heating or Cooling
• RTU Dampers Are Not Working Properly
• Just Too Noisy Outside to Open Windows
• Too Much of a Hassle to Open and Close Windows
