Jeremiah,
Thanks for the plug, but please note that both my name and Dru's were misspelled. The correct spellings are Joe Huang and Dru Crawley :-)
In response to YuanLu's earlier comment, it was never the intention of the Reference Buildings to encapsulate the best energy efficiency measures, but to provide representative computer models, i.e., "fleet averages", by building type and vintage. As buildings standards evolve and better and more recent data become available on actual average energy use, including end-uses and hourly profiles, it would certainly be worthwhile to update and improve the Reference Buildings.

If you have use them before, you should know that they are repeated many times.
The latest Chicago set should be up-dated for the exampleFiles folder, but there is no urgency. In fact, the update has caused more problems for some user following the ASHRAE guide lines..
I have download them as they were made available, but have use only a few of them to compare the differences between the up dates. The Chinese old advice for learning is " to understand the old well, then the new can be mastered."
I am not trying to stop the up date process. There is nothing "wrong" to have them up-dated. If resources are not available, it is a low priority task.

Well- I wonder how many downloads per year happen-
From the standpoint of a modeler working for a manufacture and using models to develop and innovate on product design and to create rules sets for what product to use in what applications and what climates I find them to be very useful. Also from the perspective of a modeler who is still learning they are very useful when modeling a similar building, or when creating a baseline model as to be able to check how an example is setup.
Could you be more specific about what you think is "wrong" with this set of example buildings that was originally developed by Joe Haung & Drew Crowley for DOE2 and has since been updated several times by NREL and PNL? They may not be perfect but they are the best database of models ever created to date so far as I can tell, and if they where kept up to date with versions of Energy Plus I would think they would be utilized more often.
Best regards-

I do not think it is necessary to up-date those ref. building files. Hardly anybody uses all of them.
The set in the EPlus exampleFiles folder is good enough for most.
New OpenStudio has another set in their release.
The building models do not have the best energy saving features, to minimize the use of HVAC..

Conversion from one EnergyPlus version to another is one thing. Updating (i.e. correcting problems that may have been in the files originally or taking advantage of other changes) is a different story.
Conversion is simple. Updating is not.

Thanks Brent-
Actually I received a call from someone at NREL who said that though it was not funded, someone would do it on their time- basically he said that he was calling to let me know someone was working on it-
The process of transitioning versions of the buildings library should not be something each user has to do each time, rather if the models where just updated once per year by one person it would be easier for everyone.
Thanks NREL- we look forward to the update:)

- Dear, Commercial reference building keepers at the national renewable laboratory & keepers of the 90.1 Prototype models at the pacific north west laboratories/USDOE building codes division.
- Could you do us modelers a favor>? Could you update the commercial reference buildings from their current version 5 to version 7.1? And the 90.1 prototype building models from version 6 to version 7.1?
- The Energy Plus helpdesk site>Downloads>Converting older versions files>Download zip file>Create text file using Ep launch to select all files>convert to V6> Convert to V7 process is cumbersome and makes the idea of using these files feel like work in its self. The current version updater that comes packed with Energy Plus 7.1 will not convert from version 5 to 7.1 so the downloading of items is just a bit confusing/time consuming and is a deterrent for users to get started... One of the best uses of these reference buildings is to for new Energy Plus users to be able to use and experiment with, but new users may not find the transition process to be user friendly.
- The use of the reference buildings, and the prototype baseline buildings found at the links below should be a easy to use asset, but because they are not updated in unison with Energy Plus they are not being put to use as they would be if they where maintained.
- http://www1.eere.energy.gov/buildings/commercial_initiative/reference_buildings.html
- http://www.energycodes.gov/commercial/901models/
- The subject of these models has came up several times this year on the Energy Plus support forum, so I have taken it upon my self to send this formal request on the behalf of the Energy Plus modeling community to request that the files are updated to version 7.1 and re-updated when each release of Energy Plus is issued.
- Thank you

When I select one of the commercial reference buildings in the "IDFVersionUpdater" it provides the error message:
"No approriate TransitionV-x-x-to-V-x-x.exe files found. They may need to be downloaded from
http://www.energyplus.gov
click on Add-Ons and look for the link to download the Transition programs."
However, no upgrade to the utility can be found on the EnergyPlus website.
