Best Practices

During flush-out, record exact dates, occupancy patterns (if any, per Path 2), outdoor air delivery rates, and internal temperatures and humidity levels. 

Check filters after the flush-out is complete. Some or all of the filters may be ready for replacement, although this is not required by the credit.  

If planning to pursue Option 2, also plan to pursue IEQc3.1 and all of the IEQc4: Low-Emitting Materials credits to ensure the best chances of passing the IAQ testing on the first try. 

IAQ testing is rigorous and not at all a sure thing, so take steps to increase the probability of passing the testing on the first try.

If your goal in pursuing this credit is to provide good IAQ at the start of occupancy,

Provide appropriate resources and training for O&M personnel to maintain mechanical equipment with MERV 13 filters. 

Provide adequate training and education for all O&M and cleaning staff in appropriate handling, use, storage, and disposal of hazardous liquids.

Ventilation and exhaust systems and proper filtration should be included in the commissioning scope for the

Make sure that compliance and coordination with this credit is called out in the IAQ management plan if your project is pursuing IEQc3.1: Construction Indoor Air Quality Management Plan—During Construction.
