Hi everyone,<div><br></div><div>I'm working with an EnergyPlus reference model (from the DOE Commercial Building Initiative) and I'd like to use the exact same materials and constructions in an ESP-r model.</div><div> <br></div><div>Here's the properties I can extract from the EnergyPlus model:</div><div><br></div><div>Conductivity</div><div>Density</div><div>Specific Heat</div><div>Thermal Absorptance</div><div>Solar Absorptance</div> <div>Visible Absorptance</div><div><br></div><div>Does thermal absorptance in EnergyPlus correspond to "emissivity" in ESP-r?

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”).<br> <br> 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.<br> <br> Best regards,<br> <br> Georgios<br> <br> <br> From: <a href="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a> [mailto:<a href="mailto:esp-r-bounces@lists.strath.ac.uk">esp-r-bounces@lists.strath.ac.uk</a>] On Behalf Of <a href="mailto:A.Sdei@brighton.ac.uk">A.Sdei@brighton.ac.uk</a><br> Sent: Friday, December 31, 2010 1:17 AM<br> To: <a href="mailto:esp-r@lists.strath.ac.uk">esp-r@lists.strath.ac.uk</a><br> Subject: [esp-r] export energy plus files<br> <br> Dear All,<br> <br> does anyone know if it’s possible to export energy plus models into ESP-r?
