Moisture Control in Multifamily Passive Houses

Dylan Martello, Senior Building Systems Consultant

Passive Houses are built 8 to 10 times more airtight than a typical code-level building. As a result, less moisture transfer occurs through the exterior wall assembly via air leakage through the fa├žade. This can lead to high interior relative humidity levels and pose increased risk of condensation on the building structure.

The primary means of controlling humidity levels in a Passive House is through the ventilation and heating & cooling systems.

This talk will outline an example of how this risk was assessed for a current PH project and will detail what design options are available to reduce this risk.

The presentation will be multifamily focused.
