Re: [TRNSYS-users] Effect of outdoor conditions on building load calculation

Chun Kwong,
From the warnings, it looks to me as though there is a problem with the input connections between your weather data reader, radiation processor, and sky temperature model. If you are using a standard weather file format, I would recommend that you use Type15 instead of the combination of Type89, 16, and 69 to generate the ambient conditions for your building. If you are using measured data to drive the building then you will need to use Type9, 16, and 69 (or possibly Type109 and 69) in which case, please send me your *.tpf, weather file, *.bui file and any other files I need in order to run the simulation so that I can find the connection problem. 
Regards,
 David

Dear Bradley,

I have found the way to implement ambient conditions to the Type 56
multi-zone model.  However, when I run the simulation, some warning
messages appeared and the simulation stopped after some time (see
attached listing file).  Kindly advise how I can fix them.  Thank you!

Also appreciate previous reply from Mathaase.

Dear Chun Kwong,
  You might start by looking at one of the two building examples.

Dear all,

I want to build a zone model using TRNbuild to calculate the annual
load profile.  However, I can't find any way that I can incorporate
the effect of outdoor conditions (neither in TRNbuild nor in Type 56
proforma).  Can anyone give me some advice?  Thank you!
