Hello

I am trying to model a DOE medium office building with Trnsys simulation.

But it requires validation and calibration.

How can I compare the CBCES 2003 data with the medium office model?

I found a problem with existing DOE reference models that did not compare with survey data.

I want to calibrate my Trnsys simulation building model.

Please help!

Thank you

Calibrating a TRNSYS simulation is no different than calibrating a simulation with any software. You need to compare your outputs to your measured data (or in your case the CBECS average data). Based on the differences between the measured and simulated data you adjust your model parameters and inputs until the agreement improves. There are many standards, books, and papers that cover this process.

Thank you for your kind reply.

I have seen data comparing the output of CBECS and DOE models.

But this is a big difference.

In case of mideum office, it is only half of the CBECS EUI.

Was there no effort to compare or calibrate the DOE model against actual measurement data?

And there is no medium office in CBECS.

How can I have data to compare?

I did not do any work on the creation of the DOE reference buildings. There have been a number of publications concerning the production of them. Those would be good start for understanding how they were created.
