2021-02-18 08:15:17 -0500 | marked best answer | TMY3 conversion to EPW Hi, I've received lately many TMY3 weather files (recent purchase of IWEC2). I'm looking to use them with EnergyPlus but doesn't seem to work with this type file. So now I'm looking into converting them into .epw file format. Do you have please any idea to share to reach that goal? Many Thanks, Nassim |
2020-10-01 05:22:40 -0500 | marked best answer | Fan Coil Unit - Convert cooling power capacity to maximum cold water flow Hi all, I have to size Fan coil units in my model with known cooling powers. But on EnergyPlus/DesignBuilder, we can only specify maximum cold water flow. I've checked the Engineering reference of EnergyPlus (pasge 289 - Fan Coil Unit Sizing Formula (1257)) and they give the formula linking the two entities. However, it is unclear what are the other different parameters involved, didn't find any nomenclature explaining them (quite annoying actually), especially the DeltaTloop,des. Can someone help me with it? Thanks in advance Best Regards, |

2019-03-16 06:56:26 -0500 | marked best answer | Model Translucent Panels on DesignBuilder Hello, For a project, I have for the first time to integrate translucent panels into my model on Design Builder. For now I'm considering it as a glazing with its U-value, g-value and light Transmission factor. Is it correct to consider it like that, or is there a more correct way to include it in the calculations? Thanks in advance Best Regards, |
2018-09-19 09:44:25 -0500 | marked best answer | Supply air and extract air in DesignBuilder Hello, There are several buildings across the world where the supply air is set in one place and the extract air in another. In DesignBuilder Detailed HVAC, when defining zones, one has to put the supply air and extract air in the same zone. Therefore it is not possible to simulate the airflow from one room to another before beeing extracted. Is there a way to do it? Thanks in advance Regards, |

2017-02-18 10:15:47 -0500 | marked best answer | Model Radiant Panels with DesignBuilder then with EnergyPlus Hello, I'm looking to model a SAPP ceiling Hybrid (radiant cooling and heating ceiling panel), performing cooling and heating. I've started modeling that on DesignBuilder by implementing a chilled ceiling. Since the performance of DesignBuilder is limited regarding this type of system, I moved to EnergyPlus to model the heating part of this system. In the section ZoneHVAC:LowTempratureRadiant:VariableFLow, I've tried to put Chilled Ceiling HW Water Inlet (respectively Outlet) Node in the Heating Water Inlet Node (respectively Outlet) Name section, but I couldn't find it. I also tried to replace the heating part by a radiator in DesignBuilder, but regarding the results, there are some differences with the original system. Now I'm wondering how can I model this type of system (either on DesignBuilder or EnergyPlus). If you have some experience on this issue, please share it. With Many Thanks. Nassim |
