Re: [EnergyPlus_Support] Re: Post processing on number of hours when room air temperature was more than 25[C]

You can do the same thing with timebin reporting. A binned output can use a schedule field as the last field just like all other output variables, so you can set thresholds, reporting interval as well as a schedule for when an output is to be written (like an occupancy schedule which gives zero and non-zero values, i.e. 0 won't repot and >0 report).

I would need EMS only if the conditions are many fold, like report when over threshold when occupied AND the window is open.

A client recently asked to report zone lux values at reference point 1, during occupied hours, for lux thresholds 100 to 10000 in increments of 100 lux.

The reply is a one line long timebin output entry in the idf.

Hi Waseem

I replied to you there. However, I am also posting the PPD code (which hasn't been validated but it should work) here just in case anyone else might find it useful.

Best regards,
Ivan Korolija

Thanks All. I appreciate your help. I will try these.

@Ivan: I have replied on Unmet Hours but in case you see this here. just wondering, can we do the same for PPD during occupied hours? e.g. Number of occupied hours when PPD was greater than 10%?

Thanks

Kindest Regards
Waseem
