2016-02-22 13:00:46 -0500 | commented question | GSHE with unreasonable Loads I read a post that for simultaneous cooling and heating a CentralHeatPumpSystem is needed. Is it possible that this leads to my problems? As mentioned on the Openstudio webpage "new in version 1.9.0" it should be possible to add this object but I couldn't find it in OS. |
2016-02-19 13:13:05 -0500 | asked a question | GSHE with unreasonable Loads Hi, I am trying to model a GSHE with several heat pumps in OpenStudio (V1.10.0). I used the tutorial which is already mentioned in a few other posts (District Cooling and Heating for sizing the GSHE with GSHEPro). The problem is now, that I get very unreasonable cooling / heating loads as well as pump loads. The load distribution before the GSHE was approx. even. I used an autosized variable speed pump. Do you have any suggestions what could be wrong? Thank you, Phil C:\fakepath\GSHE Loop.png C:\fakepath\Pie_Loads.png C:\fakepath\Bar_Monthly_Loads.png C:\fakepath\Electricity_Loads.png |

2016-02-03 22:02:19 -0500 | commented answer | Radiant Ceiling System Thank you very much for your comprehensive explanation. I would like to try your suggestion with the plenum. How can I do that? Editing the IDF would mean that I havw to leave OS for my future steps and I would like to omit that. |

2016-02-03 16:04:12 -0500 | commented answer | Schedule:Constant I put the screenshot into an answer. I just saw that even my newly drawn models from the SketchUp plugin have the same error. And there is no equipment assigned yet. Thank you |
2016-02-03 15:05:36 -0500 | asked a question | Radiant Ceiling System Hi, I am trying to implement a radiant ceiling system to my OpenStudio (V1.9.5) model. As shown in many tutorials I created an internal source construction, applied it to the surface and used the low temperature radiant var flow for the thermal zone. As long as applied for my first floor it works, but as soon as I try to apply it to the second floor I get the following error: * Severe * Surface SURFACE 30 is referenced by more than one radiant system--this is not allowed * Severe * Interzone surface SURFACE 55 is referenced by more than one radiant system--this is not allowed I compared two .idf files, one in which I used a BCL measure to apply a radiant floor system and one where I assigned the internal source construction by myself. What is striking is that in the model I applied the radiant ceiling system the flow fraction is shared (shown below). Do you know why this happens? I did not make this selection in my OpenStudio model. And why does the BCL measure apply an internal construction for each surface, is that necessary? Thank you, Phil ZoneHVAC:LowTemperatureRadiant:SurfaceGroup, Low Temp Radiant Var Flow 4Ceilings, !- Name Surface 55, !- Surface Name 1 0.5, !- Flow Fraction for Surface 1 Surface 60, !- Surface Name 2 0.5; !- Flow Fraction for Surface 2 |
2016-02-03 12:38:38 -0500 | commented answer | Schedule:Constant I am using OpenStudio(Version 1.9.5). Openstudio made this schedule automatically and since it is a constant schedule I cannot change it in the schedule settings. There are also 4 drop-down menus which are empty in the PlantLoop settings (I cannot select anything there). I created a OnOff schedule for my HPWH but I cannot find any equipment which uses the mentioned schedule in the errors. |

2016-02-03 09:48:29 -0500 | asked a question | Schedule:Constant Hi, I ran into following warning: * Warning * ProcessScheduleInput: Schedule:Constant="ALWAYS_ON", Blank Schedule Type Limits Name input -- will not be validated. As long as I don't use any equipment which needs the Always On Schedule nothing severe happens. But if I for example add a HVAC System were some fans use the constant schedule I get the error message below. I already tried different approaches (tried to change .osm code) but I couldn't find any solution yet. Any idea what could help? Thank you, Phil |

2015-12-10 09:36:14 -0500 | commented answer | Fan Assists Night Ventilation Thanks, I will try to apply the measure the next days. |
2015-11-25 20:07:43 -0500 | commented answer | Fan Assists Night Ventilation Thank you very much, I really appreciate your support. |
2015-11-24 10:07:24 -0500 | commented answer | Fan Assists Night Ventilation Thank you for your fast response. I used the guide you suggested above. Then I added more and more spaces to the model to see if anything unwanted happens. I wanted to try this before I am changing a lot of interior walls in my complex model. At one point, after adding one more space the simulation failed without any error messages. I am using OS Version 1.9.0, could that be a problem? Is there a way to upload the .osm files so you could have a look on it? Thanks |

2015-11-23 22:57:25 -0500 | asked a question | Fan Assists Night Ventilation Hello, I tried to use the Fan Assists Night Ventilation Measure for a very simplified model. When I added one more space to my model, with an obvious air trace, the simulation failed. Unfortunately I cannot upload my .osm files. What do you think could be wrong in my model? There is just one possible air trace and both windows are operable. Thank you |
