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 requirements for air volume, humidity and temperature.  If using natural ventilation, you can meet the air volume requirements with temporary fans and HVAC units. 
• If pursuing the testing option, pursuing all of the IEQc4: Low-Emitting Materials credits, along with IEQc3.1: IAQ Management Plan: During Construction, will significantly increase the likelihood of passing the testing and earning the credit. If not pursuing the testing option, then earning those credits won’t directly help with IEQc3.2, but they will contribute to good IAQ.
