You may want to post this question on the Energyplus support group page
or mailing list see below.

 

To hopefully answer some of your questions though the output file you
likely will want to view for your analysis is the .eso file and there is
a great viewer xEsoView that is free and is great for viewing these
outputs. To determine what variables are presented in the ESO file you
will need to add the variables from the RDD file to the IDF file if the
variables are not presently being reported. I believe you will need to
do this in the IDF editor, and if you have run the simulation once there
will be a drop down list of available variables in the IDF menu for
Reports:Variables.

 

I would recommend reporting the variables at the same timestep your
simulation is running in this case it looks like 4 time steps or 15
minutes. This can be changed to hourly though be changing the variable
reporting in the IDF file.

 

Constructions will need to be defined in the IDF file, but there are a
great amount of constructions available in:

 

EnergyPlus\DataSets\ASHRAE_2005_HOF_Materials.idf 

 

.. for getting started with.

 

good luck, and head on over to the energplus support page.

Subject: [Bldg-sim] Open Studio: Rescheduling in E+

 

Hello

I have few queries regarding rescheduling in Open Studio. Also I am a
new user of Energy+. 

1. I produce basic building geometry in Sketchup and set the available
input data. One thing that I understand from this is that Open Studio
have very limited inputs. Also scheduling is automatically set for the
simulations. Then I run the E+ simulation within Sketchup. I want only
the zone comfort i.e. (MRT and MAT). The result in excel format have
temperatures within every 15 mins. But I want the hourly temperature
only. What I have to do for hourly result within sketchup? 

2. I want to take this process further. I want to edit the scheduling
and change the building materials. What I understand from this is that
sketchup help in setting the building coordinates easily. After setting
the building geometry in sketchup, can one edit the scheduling and other
related stuff that is taken default in open studio. The (.idf file)
produce in Open Studio while saving, can this (.idf file) after
rearranging the scheduling and changing material assembly in IPF Editor
work for further simulation analysis. Can this process be done? I tried
this but its giving errors. Hope I am able to explain my query. 

Please help me. 

Thanks 

Rachit
