I don't know if it is useful, but if it is, it probably needs some refinement. Or just get rid of it.

Tehcnically it would dump some statistics (number of calls, etc, see here) to a file when you pass the environment variable TRACK_AIRLOOP (eg TRACK_AIRLOOP=True energyplus -w ../chig.epw -d out 5ZoneAirCooled.idf)

Problem is that it crashes, because on this line https://github.com/jmarrec/EnergyPlus/blob/develop/src/EnergyPlus/HVACControllers.cc#L2644 AirLoopStats is empty.

Not sure whether it is worth fixing though.

I had no idea there were so many Environment variables one could pass... Some search after discovering it in the code, shows that it's indeed in the documentation though: here's the TRACK_AIRLOOP one: https://bigladdersoftware.com/epx/docs/9-0/module-developer/air-loop-simulation-environment-variables.html#trackux5fairloop-runtime-performance-tracker-for-air-loop-simulation

@rraustad Do you use this?

rraustad commented 5 years ago

Never have, probably because I dislike the water controllers. Looks to me like a developers debugging tool.
