Winter Is Coming: Seasonal Tips to Maintain Your School Facilities

11/12/2019 (Permalink)

classroom with children Good air quality in your local schools is important and should be maintained.

Six Tips to Prepare Your HVAC System for Winter:

  • Clear exterior HVAC systems of ice or snow; clean interior HVAC elements on a regular schedule. Poorly maintained HVAC units can lead to IAQ problems, including mold issues. Microbial growth in drip pans, ductwork, coils and humidifiers can both disrupt the HVAC system and affect building occupants’ health.
  • As temperatures fall, maintain indoor humidity levels. As the temperature outdoors drops, schools should be aware of indoor humidity levels. To protect occupant health and comfort as well as the school building and its facilities, indoor relative humidity should be maintained above 30 percent—ideally between 30 percent and 50 percent.
  • Ensure air filters are changed on a regular schedule. Air filters should have a dust-spot rating between 35 percent and 80 percent or a minimum efficiency rating value (MERV) between 8 and 13, depending on the compatibility of the air handling unit. The higher the MERV rating, the more particulates will be filtered, resulting in cleaner air.
  • Adjust HVAC operation for fall or winter conditions as needed to ensure proper ventilation. Provide outdoor air ventilation according to ASHRAE standards or local code. There are significant spatial and seasonal variations in the volume of air delivered by most HVAC systems, so systems may need to be adjusted. Learn more by checking out the ASHRAE Standard 62-2016.
  • Adjust your maintenance schedule to take holidays into account. To ensure that HVAC systems are functioning properly over winter and holiday breaks, consider creating a holiday maintenance schedule. With intermittent building occupancy over breaks, outdoor air ventilation rates may need to be adjusted. Check that air registers are not inadvertently obstructed by furniture or large objects that may have been moved.
  • Activate the frost control option on Energy Recovery Ventilation (ERVs) systems as appropriate. Be wary of frost. In colder climates, some operating conditions can cause freezing within the energy recovery heat exchanger, and it is often necessary to equip energy-recovery ventilator (ERV) systems with a frost control option.
