A North Carolina K-12 Public Charter School & Home of the Kingfishers
Our ventilation/HVAC system is a continuous forced-air system that is designed to meet or exceed EPA standards.
The building maintains positive pressure at all times.
There are five rooftop units supplying 85,000 CFM (cubic feet per minute) of air. These units are set to draw in outside air. The range of outside air varies from 15 CFM per person in a classroom to 32 CFM per person in the gymnasium. From the rooftop the air is then passed to 51 variable air boxes that then heat/cool and deliver a specific CFM to meet demand in a particular area.
The system is also equipped with a bi-polar needlepoint ionization system. This system actively cleans the air by pumping both positive and negative ions into the building. These ions actively clean the air of viruses, bacteria and mold. As an example, within 60 minutes 98.33% of the SARS-CoV-2 are inactive in the air and 99.98% of SARS-CoV-2 are inactive on surfaces.
In a typical sized classroom of 700 square feet in our building, there are at least three complete air exchanges every hour.
