Acceptable Humidity Levels

Is 60% the Accepted Threshold for Humidity?

Well…it Depends….p

Building Durability would determine acceptable levels

Modeling Tool Needs/Gaps

• Construction Moisture can elevate interior RH levels (up to 9 pints per day)

• Slab on grade homes are most risky due to the enormous amount of water that is stored in concrete

• Slabs can only dry toward the interior of the house when enclosed
