DEVELOPING AN INFECTION RISK MANAGEMENT MODE

Projects pursuing this option must implement the capability of the building to operate in an Infection Risk Management Mode. This mode provides minimum equivalent clean airflow rates, calculated as the equivalent clean airflow rate per person multiplied by the anticipated number of people in a space. The building owner and facility manager must determine when to apply this mode of operation.

IMPLEMENT BUILDING READINESS PLAN

Preparatory steps and mitigation strategies that a facility will use before, during, and after an infection risk event (or period) must be documented in the IPp4: Current Facilities Requirements and O+M plan . In ASHRAE Standard 241-2023 this is called a building readiness plan.
