# Add EMPD Material Properties

## Description
Adds the properties for the effective moisture penetration depth (EMPD) Heat Balance Model with inputs for penetration depths.

## Modeler Description
Adds the properties for the MoisturePenetrationDepthConductionTransferFunction or effective moisture penetration depth (EMPD) Heat Balance Model with inputs for penetration depths. 

 Leaving Change heat balance algorithm? blank will use the current OpenStudio heat balance algorithm setting. 

 At least 1 interior material needs to have moisture penetration depth properties set to use the EMPD heat balance algorithm.
