The primary focus of this effort is to analyze specific building systems to identify what systems can be addressed to
improve indoor air quality in alignment with national recommendations. We are committed to performing
enhancements and instituting best practices for indoor air quality improvement.
The HVAC enhancements are an important component of our plan to create safe and healthy learning environments for
our students and staff, but it is not the only thing in place. In addition to the HVAC work, DCPS will be instituting PPE,
social distancing, school routine, and cleaning protocols to help mitigate the risk of COVID-19 transmission.
