Hello All,

I am helping someone do a COMCheck on our building. I was asked if Revit can read a chart (see attached image). If I knew the formulas, we could probably get as close as possible. Has anyone done this in the past? Are there any tips people can share?

Thank you,

The proper way to do energy calcs with Revit is to export GBXML, which COMcheck should import. If you are trying to calc U-factor from some formula you are going to create in a window family, you will need conversion parameters to get H, ft2, and F all in the same units, and it's probably not worth the effort. Default windows have U-factor params, I suggest you figure out how to use them.
