Re: [EnergyPlus_Support] Inverse simulation





1) Possibly your sensors were exposed to  radiation locally warming the air temperature inside the thermostat.

2) Possibly your spaces were indead not well mixed. Eplus default room air model is "well mixed".

3) Possibly envelope infiltration is not matching your real scenario.

Hi all,


I'm working on a Building model which I have to match as much as possible with the real temperatures data.


It is a simple room divided into 4 thermal zones separated by airwalls. And every zone has its own Packaged Terminal Air Conditioner.


I have been able to match the temperatures trend, but the problem that I'm facing is that the simulated temperatures in every room are almost the same, while in the real data they differ around 2-3 C degrees.


I have tried modifying several parameters but they all affect to all 4 room temperatures at the same time. Also changing the ZoneMixing parameters is not working well.


Does anyone have any suggestion about what parameters or variables should I look into detail and change in my model? Has anyone found a similar issue before?


Thank you very much!


Kind regards


Marcos Perez-Vazquez
