Re: [TRNSYS-users] Best practise for simulating several variants of different buildings

[David BRADLEY <d.bradley@tess-inc.com>]

David,
  Your methodology would certainly work so long as you are not using a shading mask (*.shm file) in Type56. If you are using the shading mask that TRNBuild can generate then make sure that your buildings are all drawn far away from each other in Trnsys3D so that they do not shade each other.
 
  When I have simulations in which I am dealing with many slight variations from one project to another I rely quite a lot on a text-compare tool such as CompareIt and I look a lot at the *.dck and *.b17 files. Even if you aren't very familiar with the syntax of these files the differences from one project to another become much more obvious than if you are looking at those same differences from the respective interfaces (Studio and TRNBuild). I still make all my changes in the interfaces and I use the comparison tool just to make sure that there aren't any unintentional differences between the projects.
Kind regards,
 David

Dear all,

 

I'm tasked with simulating different optimisation strategies for serveral buildings. There are about 10 buildings with

3-5 strategies mainly consisting of changing only wall layers or windows. My first approach was to create a base version

and then copy the project file for each variant. But this leads to quite a few project files and makes adding or changing

things like heating types or schedules tedious and prone to errors.

An idea was to create just one building project file per building with several independent zones which contain the

walls/windows of the different variants. Are there any drawbacks to this approach? Or does TRNBuild include a solution

that I'm not aware of? And if not, how do/would you handle this?

 

Thanks in advance!

 

Regards,

David
