According to studies conducted by the EPA, indoor levels of pollutants can be two to five times higher than outdoor levels. School-age children spend a significant amount of time at school, which means schools need to maintain indoor air quality through their HVAC systems. Local HVAC company Dittmer Air and Heat discusses the importance of good HVAC systems in schools.
HVAC-Related Issues In Schools
Publicly-accessible buildings, including educational facilities, can have indoor air quality affected by some or all of the following factors. All of which can be mitigated by a good HVAC system:
- Indoor air pollutants. Common indoor air pollutants include dust, germs, bacteria, and mold, which can track into the building by students and staff as they move about the facility. Volatile organic compounds (VOCs) are another indoor air pollutant that is off-gassed from common objects like paint, plastics, and aerosols.
- Temperature and humidity. High heat and moisture levels can affect the levels of bacteria and mold in a space. Classrooms, offices, and other enclosed areas must be kept at moderate humidity levels, about 40% to 70%, and temperatures between 68 to 74 degrees.
- Ventilation. Proper ventilation helps keep indoor air pollutants and moisture from building up. Airflow from the building ventilation system can also cool the room on hot days.
How a Good HVAC System Can Help Address These Issues
What is a “good” HVAC system? First, it has to fulfill the basics – heating, cooling, and ventilation – and it should be capable of addressing these issues. The following are the components that directly address this:
- Air filters prevent airborne particles from entering the HVAC system’s air handler. They need to be replaced every one to three months.
- Air purifiers installed in common areas scrub the air for indoor air pollutants and should complement the HVAC air filters.
- Properly-sized heating and cooling systems help maintain comfortable and healthy temperatures.
- Humidifier/dehumidifier systems help maintain relative indoor humidity levels.
- Adequately sized and well-maintained ductwork helps deliver air and maintain airflow throughout the facilities.
Most importantly, the people in charge of the HVAC system must be diligent in keeping up with its upkeep. Replacing the air filters when needed and adhering to scheduled maintenance appointments are just some ways to do so.
