| 2015-11-01 07:57:38 -0500 | answered a question | Adding Non-Rectangular Windows to an OpenStudio Model This should be a high priority item for E+ team - I am seeing this a major issue for BIM tools to use E+ without creating multiple pieces of window glass of several quadrilateral and/or triangular pieces |

| 2015-07-28 10:40:22 -0500 | answered a question | zoning for large building It is possible to export E+ V7.1 IDF from Revit Energy Analysis (Results and Compare). The geometry information should be as complete as in the Revit model. This same workflow is also supported in Formit Energy Analysis. |
| 2015-02-13 12:08:23 -0500 | commented answer | Openstudio Run Time There were three simulations submitted on Feb 11 and all three simulations were completed successfully, though there are several warning and severe errors in the simulation due to model characterstics. The IDF files were all correctly generated and we do not have any outstanding issues with the Cloud service. |
| 2015-02-13 10:35:52 -0500 | answered a question | Openstudio Run Time This is caused by truncated IDF input for certain objects from OpenStudio IDF, passed through the version updater. We fixed this error two weeks ago and tested it to be working well. The runtime is just a bit less than 10 minutes for this model that we received. If you are still havng problems, please send us the original idf (post it to the Autodesk Labs forum) before sending it through the version updater and we will revisit this issue. Its a challenge to find out all the quirks of how IDF is authored by various tools. Kudos to EnergyPlus team that they can handle most of this gracefully !! |

| 2014-09-12 20:57:10 -0500 | answered a question | When should I use EnergyPlus instead of eQuest and vice-versa? One of the reasons quoted during the recent Energy Modeling Conference was that VRF systems could not be simulated using eQuest. There are a number of other high performance building modeling features (too many to list here) available in EnergyPlus. Another comment I hear often is that there is limited technical support and on-going development/maintenance. |

| 2014-09-12 20:36:55 -0500 | answered a question | What is the best way to model infliltration in a building? The PNNL paper provides guidelines for EnergyPlus users and is applicable for most new commercial building modeling. The biggest challenge in modeling infiltration is that it is tempting to use this as a fudge factor when calibrating existing building energy modeling. If fan pressurization test data or other reliable ACH data is available, then I would recommend using these. |
