Is there any tool/code available that calculates energy performance according to simple hourly method of the ISO 13790?

I'm working on a web based tool that calibrates a simple model with reanalysis climate data, demo available here.

Now I'm loosely using the seasonal method of ISO 13790 together with calibrated degree days equivalents. I would like to test a bit more advanced calculation procedure that still is able to execute fast (less than ~5 seconds).

Take a look at the Energy Performance Calculator from Georgia Tech. It's an Excel spreadsheet, but there has been an attempt to covert it to Python. The EPC-To-Python GitHub repository is an attempt to open source this effort.

You might also want to take a look at this RC_BuildingSimulator github project.

The EPC-To-Python repo has jack squat in it though. Aside from the README and gitignore/gitattributes files, so I wouldn't even mention it.

Thanks Matthew! The excel tool seems to be almost exactly what I was looking for. Are there any additional references to the calculation besides the cited standards?

Marking Matthew response as a answer. But other suggestions are more than welcome :-)

Jason, RC_BuildingSimulator seems promising. Definitely going to explore that project

@Lukas, here's another one I just found: Argonne National Laboratory's ISOmodel
