2021-04-28 18:14:30 -0500 | marked best answer | Simulation time step can not be changed I just describe my problem of using energyplus below: I just generated a IDF profile by openstudio sketchup plugin and then input this IDF profile into Energyplus Launch for simulation. The problem is no matter what time step I changed in the IDF editor, the simulation results are always in hourly time interval. I quite appreciate anyone who can put a light on this issue. |

2018-01-08 17:28:03 -0500 | marked best answer | Does BCVTB support Energyplus Version 8.8 Hello everyone, I want to know if the least version of BCVTB (version 1.6) support the co-simulation with Energyplus 8.8. From the manual of BCVTB 1.6, it states that the BCVTB is tested with energuplus 8.5 or lower versions and all the examples files of BCVTB use the Energyplus 8.5 or lower versions. I have tried to upgrade one of the idf file of version 8.5 in the BCVTB example to version 8.8. After the upgrade, the co-simulation does not work. I am not sure this is due to BCVTB does not support Eplus 8.8 or somethong went wrong with my seting. Can any experienced person can confirm if BCVTB works with Energyplus 8.8? I will be grateful if someone can give me comments. |

2018-01-02 08:18:15 -0500 | marked best answer | How to set a node air temperature from outside as constant I am running the energyplus example file which is named as 'DesiccantCVRh'. I draw the system diagram in the power point as shown below. In the original model, the Outside Air Inlet Node 1 is outside air node and the temperature of the inlet air is the time varying outdoor ambient temperature based on the weather file. My question is if i want to make the temperature of Outside Air Inlet Node 1 as constant like 50 degree, 70 degree....during the whole simulation, how can i do it? What objects i need to add? |
