You can earn an Exemplary Performance point for this credit through IDc1. There are not specific benchmarks for how to earn the point, but consider some of the following options:
Following best management practices for mold-control should limit liability exposure for the project team and school district, but be very careful (and consult with a lawyer) before saying or doing anything that could be construed as a guarantee that there will be no mold.
Keep costs low by starting early in the design stage and by understanding building science - how to keep moisture out of the building and air stream, and how to manage humidity levels through HVAC design.
Since IEQc3.1, a LEED construction phasesubmittal has to be achieved before a project can be approved for this credit, don’t bother to submit IEQc10 until the LEED construction submittal. This does not mean that you should hold off until after design to plan for achieving this credit, however!
For a more comprehensive IAQ plan, you may want to include design recommendations for the architect and mechanical engineer, steps for preventing moisture buildup during construction, and for remediation if building materials become wet or moldy during construction.
