Custom Mass Opaque Material with R Value

Hi Mostapha, Chris and group members,

If I want to custom a mass opaque material, is it possible to set up with R value?

The help of Honeybee_EnergyPlus Nomass Opaque Material writes, “However, this component is very useful if you only have an R-value for a material (or a construction) and you know that the mass is relatively small. _ If you want to create a material that accounts for mass, you should use the “Honeybee_EnergyPlus Window Material” component”.

Is it possible, or my misunderstand?

Thank you in advance.

Are you trying to add a mass to the zone or set up the construction for one of the zones faces (e.g. wall, roof, floor)?

For the first one you can use “Honeybee_Add Internal Mass to Zone” and for the second one use “Honeybee_EnergyPlus Opaque Material”.
