eQuest Geometry to EnergyPlus

asked 2015-10-29 17:26:24 -0500

This is a bit of a hopeful question, but, is it ever possible to move eQuest geometry into an idf file? We have a lovely eQuest model and don't really want to rebuild. We are happy to go behind the scenes and grab vertices we don't need any other information just the straight geometry. Failing that is it possible to open an eQuest model in sketchup?

There is in fact a measure for that! It has a strange name that I dont recall, but it is there.

While this is not a eQ->E+ this is a eQ to OpenStudio geometry (surfaces, subsurfaces, space, zone) converter.

This measure is a stand-alone implementation using BTAP's equest module. Until BTAP is gemified, this is to be conisdered a hard fork of that work.

This may or may not work as this is dependent on the complexity of your model. This was created using eQuest 3.62 as the basis. So future versions may not work with this script. YMMV greatly.

The measure is contained in the following repository. Users should be able to download or git clone from this repository. This was last used successfully on OpenStudio v2.6.0

Instructions on how to use this is contained in this markdown file here

Known Issues: The converter seems to have problems with special characters (accented French and Spanish characters for example). The file encoding in Ruby and eQuest make this cause some issues. Please ensure your model does not contain special characters in your model.

Wow. That's awesome!

@Phylroy Lopez - has there been an update to this measure?

I see this is a year old, but count me in as interested in any updates concerning the capacity to create doe2 measures! I'm struggling right now to envision/create a means to distribute python-based tools (of which I suppose some might be analogous to "measures") out for others without a Python/programming background to leverage in doe2/eQUEST simulation development.

Any update to this? I have 15 years of equest models that I would love to update.

The method declaration is here part of the standards project. From there you can save or modify the resulting object to an osm file using the standard methods. Your code would look ~like this.

input_file = '\path\in.inp'
output_file = '\path\out_geometry.osm'
model = BTAP::FileIO::load_e_quest(input_file )
BTAP::FileIO::save_osm(model,output_file )

I'd add the updated measure, but I am very tight on time... but this should work for the measure savvy. YMMV.

Back in 2007, I led a team of 7 at LBNL to develop doe2ep, a modified version of DOE-2.1E that exports an EnergyPlus imf file that then goes through epmacro to produce an idf file. In contrast to other efforts I've seen, doe2ep was meant to be a full conversion including both the building and HVAC descriptions. Due to funding limits, we were able to convert 95% of the loads, 50% of the HVAC, and maybe 25% of the Plant inputs, the missing portions mainly system and plant types that were not covered. However, for what it can translate, doe2ep has been very robust, as attested by that I used doe2ep to create all the first versions of the DOE Reference Commercial Buildings (also in 2007).

In 2012, I had another project with SCE where I was tasked with converting hundreds of eQUEST/DOE-2.2 files to EnergyPlus, and developed a process using awk scripts to convert from DOE-2.2 to DOE-2.1E, use doe2ep to go to EnergyPlus 3.0, and finally the Multiple VersionUpdater to what was then current, i.e., EnergyPlus 7.2. See the report here for details.

I don't have any intentions of turning this into a self-contained piece of software, since that would take a lot of time and debugging, but I have provided this as a service on multiple occasions to others. When I get a DOE-2.2 file, I run it through my process to see what happens, and then deal with problems that occur.

@Joe Huang, your vintage is showing! :) Also, you should learn to script OpenStudio Measures. I really think you will love it.

Hey Annie - here are a couple options:

I haven't used any of these and the last one is the OpenStudio measure Amir mentioned. As far as I know it's not publicly available, but @macumber can probably send you a copy.

I think it lives here, but no guarantees.

Looks like that might be it, nice jiu Gitsu.

@Eric Ringold that is the correct link, if you want to easily download it you can use this link to download the whole repository as a zip, then you can copy the measure from lib/btap/measures/btap_equest_converter to your My Measures directory.

oh my goodness you are all amazing!

@macumber, thanks for the information. I downloaded it and copied to my directory. However, it said "failed to compute arguments for measure: cannot load such file". Is there anything else we need to do after we download? any change to the measure?
