Option 1: Flush-Out
Option 1: Flush-Out
Depending on your climate and the time of year the flush-out will be completed, the energy costs of doing a flush-out could vary significantly. Estimate this early on, to help inform your chosen compliance path.

Pursuing this credit through Option 2: Air Testing can allow for an earlier move-in date than might be possible when pursuing a building flush-out. IAQ testing can be a quicker process if your project team can ensure that the air contains very little contamination at the time of testing. However, there is always a risk of failing the test, which results in the need to flush-out the building again and retest—or forfeit the credit.
Many teams consider Option 1, but ultimately choose Option 2 for one of two practical reasons:Scheduling the flush-out is not possible.The building’s HVAC will not be able to maintain the required temperature and humidity levels for the duration of
Many teams consider Option 1, but ultimately choose Option 2 for one of two practical reasons:
Scheduling the flush-out is not possible.
The building’s HVAC will not be able to maintain the required temperature and humidity levels for the duration of the flush-out. Doing so will also be energy-intensive.
If your goal in pursuing this credit is to provide good IAQ at the start of occupancy, IAQ testing is the best way to confirm it, even though it doesn’t guarantee that you’ll earn the credit. (If you initially fail testing, you can do a flush-out and rete
If your goal in pursuing this credit is to provide good IAQ at the start of occupancy, IAQ testing is the best way to confirm it, even though it doesn’t guarantee that you’ll earn the credit. (If you initially fail testing, you can do a flush-out and retest, however.)
If you follow the flush-out procedures required under Option 1, you will earn this credit, while if you follow the testing procedures under Option 2, you may earn the credit if your project passes the tests. This lack of certainty under Option 2 leads man
If you follow the flush-out procedures required under Option 1, you will earn this credit, while if you follow the testing procedures under Option 2, you may earn the credit if your project passes the tests. This lack of certainty under Option 2 leads many project teams to pursue Option 1.
Consider whether Option 1 or Option 2 is a better match for your project. Review the following tips, along with more details on each option below.

Choosing an option
Depending on which of the two options you choose for this credit (see Schematic Design), you should start to consider the following two things during predesign:If you pursue a flush-out, you’ll need a mechanical system with the capacity to meet the credit
Depending on which of the two options you choose for this credit (see Schematic Design), you should start to consider the following two things during predesign:
For projects with more than one main entrance, you may draw a circle from more than one entrance. The area contained within the circles drawn from all these radii is then used as your project’s radius.
