  • You may have already earned this credit

    You already addressed this credit as part of the compliance process for IEQp1: Minimum Indoor Air Quality Performance. If the measurements you took for IEQp1 indicate that your building has ventilation rates that are at least 30% better than ASHRAE 62.1-2007 for every ventilation distribution system, no further action is required, other than checking that any needed documentation is uploaded.

    If, on the other hand, your ventilation rates are not at least 30% better than ASHRAE 62.1-2007, you’ll need to consider whether it is appropriate to pursue this credit.

    Pros and cons to more fresh air

    If you need to increase ventilation rates throughout the building to reach the 30% threshold, you will also be increasing your HVAC energy consumption and...

Mechanical ventilation systems with operable windows

What if my mechanical ventilation was sufficient to meet ASHRAE 62.1 minimums AND the majority of my rooms had operable windows? Could I use the operable windows to meet the 30% additional ventilation for 90% of spaces?
