Projects have a choice of strategies for credit compliance, based in part on whether they are naturally or mechanically ventilated.
Option 1: Enhanced IAQ Strategies
Entryway systems, cross-contamination prevention, and filtration will add construction cost to a project, but not significantly. The ventilation calculations present some added soft costs, but these would be shared with EQp1. 
Option 2: Additional Enhanced IAQ Strategies
Projects can choose from one of the following strategies, depending on ventilation type.
Cost Synergies
EQp1: Minimum Indoor Air Quality Performance
EQc4: Indoor Air Quality Assessment
