I just have a couple questions about the values for the embodied energy/carbon calculations. My first question is where the default values for embodied energy and carbon for the various materials come from? I assume something like Athena, but I just wanted to confirm so I can answer the question when someone asks me.
My next question is that I was looking to the constructions for the structural component of the building templates in the template editor. I wanted to make one for concrete, to add to the existing ones for steel and wood frame. I am curious as to the values that are required, namely the "Normal Ratio" and the "High Load Ratio", both with units of kg/m2. I googled them and I am not sure what property these names are referring to with these units. My only guess could be the self weight of a beam or slab based on the cross section, and then multiplied by the length of the beam.
Thanks for the help!
