We come across with a issue of loading of hourly data in design builder analysis tab when run it for yearly analysis. Can anyone help us how to overcome on this issue, and how to limit to ask for a hourly data in Design Builder.

Below the Design Builder Note below loading the result.

The eco file you are attempting to load is too large for DesignBuilder to load all of the data, would you like to load it without he hourly and sub-hourly data ?

Your help is much appreciated,

Thank you.

Have you asked for temps node/mass flow rate node output, or surface heat transfer? It can results in a tons of output Designbuilder (but you too..) cannot handle.

You have to select what is important for your analysis.

In case you need only some specific variable with hourly timestep for a whole year simulation , you have to

  • for envelope and gains related data: select "Allow custom outpu2 in Otpions > Simulation > Output

  • for plant/system data: include an IDF code piece at the end of that resulting by the DesignBuilder translation (DesignBuilder model into EnergyPlus model), attaching it via Option > Simulation > Advanced > Include IDF Data . This piece of IDF shuld be like:

Output:Variable,XXX,System Node Mass Flow Rate,timestep;

Output:Variable,XXX,System Node Mass Temperature,timestep;

with your plant node instead of XXX.

Also take a look at the guidance in the Program Help under the Reference Section (bottom of index) or search on the term Working With Large Models.
