Ventilation System Improvements

Filters Upgraded

Upgraded to MERV-13 Filters., which filter down to 0.3 - 1.0 micron particle size.

Airflow

Air exchanges increased to a minimum of 25% outside air exchange. CO2 sensor adjustments allow for fresh air intake to be increased to 100% clean air exchanges when required.

CO2 Setpoint Lowered

Lowered the setpoint in all buildings from 1000 parts per million (ppm) to 800ppm to ensure a higher concentration of outside air during occupancy.

Ventilation Hours Expanded

Expanded ventilation operating hours to be from 6 am - 8 pm (some schools expanding to 11 pm to account for custodial staff and events after hours). Extending hours ensures schools are flushed with clean air before students arrive and after students leave.
