I have a question regarding default material properties

Hi

I am aware of that honeybee will take default materials for HBSurface based on surface type.

Where can I check the default material properties in HB? (for example, U value of the default wall or u value)

Furthermore, I would like to know the information regarding the values derived from the building program, when we use ListZonePrograms.

It will be much appreciated if you can give me some information regarding this matter.

Thank you!
