[EnergyPlus_Support] Re: EnergyPlus Units

["tochs2002" <ochs@xxxxxxxxxxxx>]

I just want to add my support to the plea for the availability of IP 
units to the EnergyPlus software.  I am presently working with an 
older building and it is confusing to try to reconcile the input and 
output for EnergyPlus with the measured and documented values for the 
building.  I would like to see it added to the "wish list" for future 
releases.  I don't think this is a "front-end" issue which can be 
relegated to the interface developers.  I would imagine it could be 
as simple as a switch in the first few lines of data to the engine 
which then tells the engine what units it will be receiving.

units is common to Academia where EnergyPlus originated and the 
Government in it's all knowing wisdom is pushing the SI system but us 
poor engineers and architects have over 100 years of drawings and 
specs in the IP (Inch-Pound) system that must be translated into SI 
to make it work with EnergyPlus and in my case retranslated back to 
IP so I can understand the results.

link EnergyPlus to an excel spread sheet so that the data can be 
entered in IP transmitted to EnergyPlus in SI then have the results 
transmitted back to the spread sheet so they can be converted into 
IP?  Designing and programming the spread sheet for the automatic 
double translation is not a big problem the real problem is the 
automatic data transfer links so the data does not have to be entered 
three times for each use of the program.

there will be a need for a either a translator or a IP version of 
this EnergyPlus program and all of the country's academia and 
governmental edicts will not change that.  Most of the existing 
buildings were designed and built prior to electronic drafting 
programs where the translation of the graphic part of the input data 
is only a few clicks away formatting the drawing's units.  But this 
still does not translate the facility design data such as air flow, 
unit sizing, and etc.
