As more and more families depend on away-from-home childcare, the expectations for quality care have steadily risen, even for the facility itself. The demands that pertain to such care facilities are vital, and proper air quality is at the top of the list. There are innumerable sources of indoor air pollution in childcare facilities, so much so that the air is considered to be as much as five times more polluted than outdoor air! Children are more susceptible to the effects of contaminated air because they breathe in more oxygen relative to their body weight than adults. Therefore, it’s essential that childcare facilities invest in a great heating, ventilation, and cooling system–one that maintains great indoor air conditions through satisfactory ventilation and filtration. In some parts of the country, natural ventilation can be an energy-efficient way to supplement an HVAC system. Be that as it may, uncontrolled ventilation with outdoor air can allow outdoor air contaminants to bypass even the best of HVAC filters. Harmful airborne particles can include pollen, mold, creature dander, pesticides, and even bacteria. The ventilation aspect of the heating, ventilation, and A/C plan should be rated using a Minimum Efficiency Rating Value to ensure that proper air quality is provided–not to mention adding to the longevity of the actual system itself. And although a common HVAC plan has numerous features, the control of outdoor-to-indoor airflow may not always be included. Consequently, daycare facilities should demand that this feature be included with their system. The duct systems should also be dirt- and moisture-free to prevent mold growth. Extra attention to this factor cannot be emphasized enough. Finally, the installer that designs the plan for the facility should take care to label all components to help the facility personnel properly operate and maintain the system.
