Re: [EnergyPlus_Support] Energy plus model calibration





Dear Heba,

Thanks Jim for your attached file, it helped me too...

I'm sure that was a great presentation (Y).
I'm calibrating a model with DesignBuilder. and have a question !!

If it is hybrid apartment, I calibrated the conditioned and unconditioned zones separately,

For the unconditioned zone, I compared the real measured temperature with the output attempts from DesignBuilder, after changing in the uncertainty variables, and made them as less as possible.
then performed the stats. tests like MBE, RMSE, and correlation coefficient, to choose the near-to-actual curve from the measured temperature.

For the conditioned zone, I made the same actually, to compare between temperatures.

My questions are:
- is that right?
- what's the difference between the calibration of a conditioned and non-conditioned zones?
- If I have the actual energy use of the air-condition of that zone, should I compare it with the cooling loads of the modeled one?

Thanks for concern, and if you could send me also some reading materials or URLs, I appreciate.

Heba
