[EnergyPlus_Support] Re: Parametric PCM simulations [3 Attachments]

Hi Jeremiah,

Thanks for the reply, I just noticed that I uploaded the wrong file, here's the correct one.

I might have worded that one incorrectly, but what I was trying to achieve in this parametric simulation is to determine the optimum phase change temperature given the weather data, i.e. similar to what the Singapore study did.

The researchers used values from 22-32C[1st image attached] wherein the simulation results [2nd image attached] that the optimum Phase Change Temp is 28C.

-------------------

I'm not sure though if I have the parametric simulation set up correctly because the results I get are completely unexpected:

(this is a snippet of the results that I got from the simulation)
