Also, I am writing a python code right now using eppy, but I'm struggling to extract the sized values from the .eio file and to match the field names from the .eio files to the actual field names in the .idf file. Any recommendations on how you did it with python? Thank you!! |
| 2017-03-20 16:07:17 -0500 | asked a question | use autosizing values for next simulations I am running a parametric analysis using prototypes that are autosizing most HVAC components. How can I run this prototype once, to obtain the values auto-calculated, and then fix those values for subsequent runs. I do not want each run to autosize the HVAC system, but to use only the autosized values from the 1st run. |

Is there a way to set up the .idf to use the weather file given to EP without having the objects I ask because I want to know if I can set up EP parametric simulations in which I use the same .idf file for different locations and then I only change the weather file provided in each run. |

Hi, Is there a way to set up the .idf to use the weather file given to EP without having the objects Site:Location and SizingPeriod:DesignDay? I ask because I want to know if I can set up EP parametric simulations in which I use the same .idf file for different locations and then I only change the weather file provided in each run.

| 2015-09-18 08:46:50 -0500 | asked a question | How to select appropriate DesignDay objects for Winter and Summer from ddy or ddm files Hi, I want to update the .idf files with the appropriate SizingPeriod:DesignDay for SummerDesignDay and WinterDesignDay. The weather files I'm using are the CZ2010 versions, which I obtained from White Box Technologies. When downloaded, they included .ddy and .ddm files. But how can I adequately determine which DesignDay objects to choose from within these files (they include Clg 0.4%, 1%, 2%, and variations of DB, WB, etc)? Also, the .ddm files include options for SummerDesignDay for each month of the year. Is it wise to have 12 SizingPeriod for SummerDesignDay to represent the 12 months? Also, is there an easier way (other than use some python code) to automatically update the .idf files with these DesignDay objects? Thank you in advance for your help! Pablo |
