this would suggest errors in setting geometry for WWR in the idf file. What confuses me is that the error manifested itself when moving from version 1.5.2 (where it worked fine) to version 1.6.3. Any suggestion?
Hello there,
I have come across the very useful example posted (I believe by Ivan?) regarding the use of WWR to manipulate window geometries in jeplus. The example "presents the simplest case, in which the window is located in the centre of the wall, and its width and height are proportional to the overall size of the wall according the WWR".
While this is brilliant, I wonder whether you could advice on how this could be implemented for more than one window, without doing this manually.
If I have, say, a 1bedroom flat where two rooms have 1 window each, I would like to be able to set the wwr for both by ensuring that the window centre is defined as a dependant parameter from vertexes of the hosting wall.
Should that be best done in jeplus by replacing values with labels and subsequently specifying that in jeplus?
Hi there,
I recently started to use jeplus and I am testing a workflow (i.e. generating an IDF file, performing parametric simulations, collecting results etc.).
I have simplified an existing E+ example IDF file (simple house), loaded that into jeplus and played with building orientation (used label @@north@@).
Simulations are performed and results collected. However this results in all simulations outputting the same values for relevant output variables (i.e. zone ambient and operative temperature, or Zone Exterior Windows Total Transmitted Beam Solar Radiation Rate).
I have checked the local IDF files (in.idf from sub-folders) and the north angle appears to suit the jeplus parameter change.
I am testing on the example in the folder "example_2_SimLab_E+8.3" from the "jEPlus_v1.6.3" package. From the manual online, I knew I need to specify the file to be "project.jep", job list in file "joblist.csv" , and set up the working dir to be ../output_ex2/. Now I am trying to run this simulaion in Matlab without GUI, because I have hundreds of "joblistxx.csv" intending to run in jEPlus. The following is my Matlab code to call jEPLus and run the example:
I expect the code would use the file "project.jep" and test the joblist "joblist.csv", then export result in output folder. But it does NOT work as I expected. Could you please help me out on how to set up to achieve my expectation?
When I hit "Validate Project" after defining the 3 required files (weather, IDF and RVI) and defining 2 parameters, jEPlus freezes. It just says the following and nothing happens (see the attached image):
Welcome to jEPlus!
The project contains:
Validating jobs. Hang on ...
The jEPlus version is 1.6.3 and the EnergyPlus version is 8.4.0.
Hello colleagues,
first, sorry for crossposting because I wrote in advance in the EnergyPlus group but after more testing time I think the problem is in Energyplus.
I'm performing a simulation and I have a lot of output variables in my idf.
So I want to select some of them and create a csv file using the rvi file.
The problem is that the csv file obtained only have the first 3 of the 9 variables I listed in the rvi file.
This is the code of the rvi file:
Code:
eplusout.eso
eplusout.csv
DistrictHeating
DistrictCooling
ElectricityNet
Zone Ideal Loads Supply Air Total Heating Energy
Zone Ideal Loads Zone Total Heating Energy
Zone Ideal Loads Outdoor Air Total Heating Energy
Zone Ideal Loads Supply Air Total Cooling Energy
Zone Ideal Loads Zone Total Cooling Energy
Zone Ideal Loads Outdoor Air Total Cooling Energy

Output:Variable,*,Zone Ideal Loads Outdoor Air Total Heating Energy,Monthly; !- HVAC Sum [J]
Output:Variable,*,Zone Ideal Loads Outdoor Air Total Cooling Energy,Monthly; !- HVAC Sum [J]
All the data from the outputs are included in the eso file.
Could someone give me a hint what I'm doing wrong?
I try in other file without parametric studies and the same variables and the csv have all the variables. Could it be something related to blank spaces for the variables that are not listed in the csv?
I am trying to run a parametric study of a building for which I have 20 Actual Meteorological Years (AMYs) in weather file form and I will also vary some building parameters in my idf.
What I would like to achieve is have every weather file say 50 times and for each of these times randomly sample all other parameters.
What I want to ensure is that each weather file is selected an equal number of times while the other parameters are treated randomly.
Trnsys deck file (.dck) can be parametrized using tags @@ and Paramter tree but building information (materials, layer thickness,...) are defined in .b17 file which is called from line in .dck file. Is it posible to manually include .b17 file and add parameters in jEPlus project ?
