[esp-r] Re: export energy plus files

[Jon Hand]

An update - I am working on export from ESP-r to V3.0 IDF files.  I think I have worked out
the logic for geometric export so that 'doors' in ESP-r will be correctly exported.  I have
also updated most of the export of casual gains to use the newer common blocks (that is
still work in progress and needs testing)

Although there is a general movement in the ESP-r community to explicitly represent frames around
windows this creates a parent/child/grandchild situation which E+ really does not like.  One
idea is to split the parent surface in two so that the frame is no longer a child surface.

This work should be finished in the next couple of weeks and should make its want into
the development branch.

The reverse operation of scanning in an E+ IDF file - that should be technically possible
and the question is whether there is sufficient interest in the community to make it
worth doing.

Arianna,

I should have read your question a bit more carefully. I am not aware of a way to convert an E+ model into an ESP-r model. I thought you were asking the opposite.

Best regards,
Georgios

Arianna,

The answer to your first question is yes but only to version 2.0 of EnergyPlus. You can then use the EnergyPlus transition utilities to bring your E+ model back to the latest version. The conversion from ESP-r to E+ is done only for the basic model features (geometry, materials and basic operations). It has been many years since I did this but I remember there is one limitation in the process: make sure your model does not have any doors. You can find the export option in the first menu of Project Manager (press “export current model”).

The answer to your second question is again yes. However, I think that you need to convert your model files from DOS format into UNIX format and you need to correct the lines in the model files that include “C:/Esru/…” into whatever folder your model is in the cygwin area. There are many easy ways to do this process. I tend to use editors such as “Notepad++” in Windows or “Nedit” in Linux (same for cygwin). There was a script somewhere in the source code I think that could do all this automatically but I have never tried that.

Best regards,

Georgios

Dear All,

does anyone know if it’s possible to export energy plus models into ESP-r? And can cfg files created by the native windows version of ESP-r be open and modified by the cygwin version?

Thank you, very happy new year to all! Kind regards,
Arianna
