Problem in orientational survey with E+: the results differences are not explainable
I study the wall application of configurations with reflective insulation systems in different climates. I have conducted a macro parametric investigation with EnergyPlus version 9.2, using Python scripts to run the models. I studied the impacts of orientation on the energy consumption of my models using the script to rotate the models with 1 degree intervals. I faced an unexplained difference between results with changing the model orientation(I have also conducted the simulations manually in some orientations and the same results are obtained). The variations in energy consumptions by 1 degree increments are not explainable and I can provide the outcomes. I simulated in 360 degrees (Angle) and in 6 different climates of iran (Location) using the weather data files available on the EnergyPlus website, and this issue happened in all of the outputs. I used 7 different models in simulations (which is shown by 1,2,...,7). Differences in results with 1 degree differences are not explainable and I believe there must be a problem in Energyplus calculations.
I would like to ask you about the reasons of this issue and possible solutions.
Please answer my question🙏`
@arash can you include images in your question post to let us know why you think EnergyPlus is not accounting for changes in orientation correctly?
@Aaron Boranian excuse me to ask it but as I am new to this site I couldnot upload the image from my problem..can you tell me how can I do it?
@Aaron Boranian the image is attached now...the difference in one degree orientations is strange and the reseon is not clear for me...
@arash how are you using this Angle variable to change input fields of the IDF? To change building orientation, all you should do is set the North Axis input field of the
Building
object.
