NC-2009 EAp2:Minimum Energy Performance

EnergyPro for Whole Building Energy Simulation

We have a project in which they are attempting to use EnergyPro to show compliance for credits EAp2 and EAc1. Has LEED been accepting of EnergyPro models for this credit, when it does not allow for very detailed inputs into the model, vs. more complex software like eQuest or Design Builder? If we submit an EnergyPro model, since it automatically generates the baseline model for you, how do we fill out all the info for the Excel sheet Section 1.4 Tables for LEED, if we don't know the inputs they used? Does LEED still require this Excel sheet if you submit an EnergyPro model? Also, the energy model was previously built on EnergyPro version 6 (6.0.5.4), which only allows for simulations vs. ASHRAE 90.1 - 2010. While EnergyPro version 5 allows for simulations vs. ASHRAE 90.1 - 2007, it does not allow you do open models created in version 6 or allow you to backsave down to version 5, once it's been opened in version 6. Would LEED accept an EnergyPro model ran on EnergyPro version 6 against ASHRAE 90.1 - 2010, since it should be stricter than 2007 anyways? Or will we need to start over from scratch either on EnergyPro version 5 or another program such as eQuest or Design Builder? Thanks,

EnergyPro meets the Title 24/Appendix G criteria for acceptable modeling software. You can still see the input summary reports within the software. Many of them are in the .sim file which is generated for every DOE2 software. For a 90.1 submission a summary of the inputs are still required. For a Title 24 submission provide the required Title 24 reports summarized on the EAp2 form. It would probably be acceptable to use the 90.1-2010 baseline but you will likely be losing points in LEED.

Check with Energy Pro Support regarding opening the file in Version 5. I have ran models created for Title 24 2013 (version 6) in Title 24 2005 (Version 5) for LEED with a bit of tweaking.

Thank you. Yes, we have found out that in June they released a version of EnergyPro 5 (v5.1.9.12), that will allow you to open files from EnergyPro version 6, while previously it did not allow you to do this, so we should be able to use this software to run it against the proper standard.
