Dear All,

I would like to post this link to provide a source of discussion pertaining to IES <VE> software. Being fairly new to the energy modeling career, I am trying to stay on the front end of energy modeling software. I have been in the energy modeling field for 2 years currently working with Trane TRACE 700 and eQUEST, with successful LEED submittals with both programs. However, throughout this time period I have run into roadblocks that require a workaround solution, which led me to look for a more advanced energy modeling program. My most recent issue is the modeling of chilled beams, and the restrictions in TRACE and eQUEST.

IES <VE> is the software package that initially stood above the rest throughout my research. I downloaded the 30-day trial version in order to test the software, and the energy modeling potential seems endless with the APACHEHVAC and MODELIT. Before I dig deeper into this software, I am looking to get an opinion from fellow professionals who have experience with the software. Please see below for an outline of topics that I am skeptical about with switching to a new modeling software.

• Load Calcs - Accurate load calculation results
• Ease of creating building model - From my initial analysis of the software, it appears to be extremely easy to import a .dxf file to trace out with the MODELIT software. In addition, I tested importing a gbxml file, this was more difficult in regards to the fact the architectural model was not fully complete.
• APACHE HVAC - In comparison to other software programs this appears to be more powerful in the sense that you can modify select components of the system and the program will provide a visual representation of the system.
• Modeling Ouputs - Due to time constraints I have not completed a model to a place where I am able to to produce the output reports. Any information on the layout and types of reports available would be appreciated.
