[Bldg-sim] White Box Technologies announces the establishment of a Center for Open Source Building Simulations

[Julia Beabout]

Good point.  Thanks for pointing that out.  My understanding is that they use actual weather data from weather stations where they exist.  So, if you happen to need weather data for one of those sites, then you are getting actual weather data.   If you request an "in between" site, then they interpolate via triangulation to get that weather data.  However, they appear to be able to take into account specific details of your site such as elevation, landscape, etc if you have that info.

I was referring strictly to the ESTSC/LBNL version of DOE-2.1E.  I am aware that Jeff has another version of 2.1E that bifurcates from a certain point,
and have talked to Jeff about this.  I want COSBES to be a platform for open source computing, not a platform for finger-pointing and reconstructing
15 year old history.

I admit the title may sound a bit on the grandiose side, but it capsulizes my thinking on what may help our little world of building energy simulations - a non-profit non-commercial center on simulation programs and resources that's in the public domain.

My first steps are simply to maintain an open-source version of DOE-2.1E. DOE-2.1E has been effectively abandoned by LBNL and DOE for close to a decade. I have assurances from LBNL that it's only a matter of paperwork for them to make the program open source, and have communicated to them my intentions without receiving any objections.

That would of course depend on the public's (your) interest and need, which is one reason for this announcement! But for starters, I have a backlog of completed work that have never been incorporated into the public release version of DOE-2.1E, such as two-dimensional and combined response factors for composite walls, a decent foundation model, and an improved weather file format.  In addition, I'm currently working on contract for ORNL to incorporate AtticSim into 2.1E. Lastly, I have a license from LBNL to continue working on my last major work there - a partially-completed DOE-2 to EnergyPlus translator (doe2ep) that, funding pending, can be updated to the current EnergyPlus release. Also in the works and soon to be launched are (1)  VisualEPlus, a graphical user interface for EnergyPlus done by colleagues in China, and (2) actual-year weather data
 service accessing NCDC's massive International Surface Hourly (ISH) data base.

>> I had originally thought of calling a meeting at ASHRAE to make this announcement, but then realized that finding a time to meet at ASHRAE is an impossibility. However, I would be happy to entertain any questions and comments while at the conference, where I'll typically be found in TC 4.7 and 4.2 meetings. For course, I'm also open to questions and comments posted on BLDG-SIM, although my responses will be somewhat delayed.
