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).
