Hi Christoph,
thank you for your answer. The thing is, I would like to directly input the specific solar radiation (calculated in Grasshopper) onto the windows outside surfaces and only the windows,
not input general solar radiation for the whole building. But I guess this is not so easy, as I still would like to have the general solar radiation calculated on the building by TRNBuild to keep precision in thermal calculations apart from windows.
I thought about TRNLizard aswell, but as I understood correctly its a plugin for Grasshopper. I would like my main module to be TRNSYS, as it calls CONTAM for ventilation and MATLAB for control purposes. If I use TRNLizard can I then still edit my TRNSYS
deck file to implement these two softwares, as well as edit the Type 56 file to define manual inputs and ouputs?
Additionally, I have seen that Pigeon is the CONTAM plugin for Grasshopper, therefore ventilation calculations could be implemented through this plugin. But I'm still not sure how to establish the connection from MATLAB to TRNSYS and its Type 56 by using
Grasshopper as my main module ?
Thank you for your help and best regards,
Daniel

you can input your solar radiation by changing the “Orientations” to “Free format” and “Calculation of radiation data - External by another component” in TRNBuild. After updating Type56 in Simulation Studio you can get an Input for IT, IB and AI.
Because you are working with Rhino/Grasshopper and TRNSYS – have you ever thought about using TRNLizard? TRNLizard enables thermal and daylight building simulation based on detailed 3D geometry of Rhino. You can also parameterize your geometry and other input data for design studies in earlier stages of the design phase.
Best, Christoph

Hi TRNSYS Team,
I am using Type 56 for a 3D multizone building model. My building has quite a complex glass geometry, therefore I am calculating the solar radiation on the windows in Rhino/Grasshopper/Ladybug. Now I would, preferrably, like to input this solar radiation onto the windows OUTSIDE surfaces in TRNBuild and thus take advantage of TRNBuilds sophisticated window model. Is there any way to do it this way?
Otherwise, I had in mind to just convert the solar radiation onto the windows with a simple equation to heat gains to the room and input them directly to the thermal nodes in TRNBuild. Additionally, I would still model the windows for thermal heat flux calculations to the ambient, but make them totally opaque (define windows with g value of 0).
Do you have any inputs for this problem?
Thank you and best regards,
Daniel Weber |
