HOW HEALTHY SCHOOLS SAVE MONEY
INDOOR AIR QUALITY
Clean the air, save money. Sounds simple, but how? The best way to keep your air clean is to not let it become dirty in the first place. This means prevention by identifying, stopping or controlling sources such as idling vehicles; lack of proper entry matting; particles from poorly filtered vacuums or HVAC systems; chemi-
cal VOCs from building, furnishing or cleaning materials; fragrances in prod- ucts or on people and poorly sealed or insulated buildings.
It also means ensuring ventilation in a manner that does not inflate energy costs, either on a room-by-room basis via a central HVAC system or using a Heat Recovery or Energy Recovery Ventilator (HRV or ERV). Still, the cost of energy is less than the cost of an absent teacher or student.
Per Jeff May in his book, My Office is Killing Me, “One indoor air quality professional estimates that the annual cost of an employee is about 100 times greater than the energy cost to keep a building heated, cooled and ventilated for that one person. If an employer saves an energy cost of $1 a day by
reducing the ventilation in a building, and an employee who is paid $100 a day misses a day of work because of illness, the employer’s net loss is $99 (the salary is paid to the employee even if he or she is out sick).”
The Environmental Protection Agen- cy (EPA) cites increases in Average Daily Attendance (ADA) as a main benefit to schools with better indoor air quality: “The majority of a school’s operating budget is directly dependent on ADA, so even a small increase can significantly boost the operating budget.”
Evidence shows a clear association between IAQ and respiratory ills, in- cluding asthma. Per the CDC, asthma is a leading cause of school absenteeism.
Per the Connecticut Foundation for Environmentally Safe Schools: “Lock- port Township High School in Lock- port, IL, reported a three percent in- crease in the average daily attendance after the first year of implementing an Indoor Air Quality Management Plan.”
“Schools in Syracuse, NY, docu- mented gains in attendance of 11.7 percent, which yielded added state funding of $2,512,250.00 the first year after using a cleaning for health re-
gime. The school district’s use of high- efficiency filter backpack vacuuming, systematic disinfecting of desks and surfaces were among the measures used in the program.”
Per EPA: “Evidence continues to mount demonstrating that indoor air quality, or IAQ, directly impacts student academic performance and health.”
“In one study, students in class- rooms with higher outdoor air ventila- tion rates scored 14 to 15 percent higher on standardized test scores than children in classrooms with lower outdoor air ventilation rates.”
“Studies demonstrate that improved IAQ increases productivity and improves the performance of mental tasks, such as improved concentration and recall in both adults and children.”
>> William J. Fisk, of Lawrence Berkeley National Laboratory, estimated fiscal gains of better indoor air quality amounted to savings “of $6 to $14 billion from reduced respiratory disease; $2 to $4 billion from reduced allergies and asthma; $15 to $40 billion from reduced symptoms of sick building syndrome; and $20 to $200 billion from direct improvements in worker performance...” and that “potential financial benefits of improving indoor environments exceed costs by factors of 9 and 14.”
