Re: [TRNSYS-users] massive buildings

Thanks, so you believe that by increasing the timesept the results will be more accurate for massive walls. 

I am using 1 hour for timesept because it is easy to deal with the results.

Still I tkink that Trnsys is not very accurate for massive constructions.

Best regards

Hello,

you can simulate it as one wall, but have to increase your timestep in
the Trnbuild file.

Betreff: [TRNSYS-users] massive buildings

Dear all

I am working with massive buildings and it is been difficult to relate
the results from trnsys with others simulation tools because of the
big difference among them.

I need this comparison to validate a model for other studies.

I have two questions:

1. Which is the best way to simulate a heavy wall?  Is divining the
massive part in many layers or creating a fictive mass less layer?

2. How can I know ( for comparing purposes ) the amount of the total
gains that are being useful to the simulation.

All tips are welcome, thanks.

Eunice
