RESTROOM EXHAUST CONTROL

• Increase restroom exhaust rates as much as exhaust and make-up system capacities allow. • Maintain continuous exhaust (24/7). • Provide fresh outside air to restrooms in lieu of passive ventilation. Utilize reheat coils to prevent overcooling. (Ensure restrooms are still maintained under negative pressure) • Investigate make up / transfer air sources. install dedicated systems if necessary. • In addition to modifying restroom exhaust control, lowering toilet seat lids before flushing should be encouraged.
