2020-06-14 23:50:09 -0500 | marked best answer | Making a python module based on eppy Hi everyone, I’m a newb with Python and Eppy (apologies if I’m not using the proper programming terms), and I’ve been trying to make a class with different functions to work with Eppy. So, you can see in the files attached 2 modules (MyModuleV00, which works but not the way I’m trying to, and MyModuleV01, which is the one I’m trying to make work), 2 scripts using them (Working_with_MyModuleV00 and Working_with_MyModuleV01), and one IDF file to test it. So, what I’m trying to is to simplify Working_with_MyModuleV00 by avoiding the use of the variable idf1 in each function, or even avoiding all the lines above z=MyClass(… When I run Working_with_MyModuleV01 line to line, everything seems fine, however, when I open the new idf, there is no change with respect the older one. The functions should modify the existing People objects in the IDF, and add the object ZoneControl:Thermostat:OperativeTemperature for each zone in case there’s no such an object in the model. Can anyone help me please? Thanks in advance. Files attached: https://drive.google.com/file/d/1o8g5... |

2020-03-17 09:27:54 -0500 | marked best answer | Error when adding manually EMS script with Loops Hi everyone, I'm trying to add a EMS script with loops manually to a IDF (that is, copying and pasting the script), but I get the error below when I try to simulate. I just realised that I could use 'for loops' in eppy to add an EMS object for each zone, and therefore omit the zone loop, but i'd like to know if anyone knows an easier way to make this script with loops work, considering that the script should be added manually to the IDF. In the following link you will see 2 IDFs: one with loops within the scrip (which works), and one without loops within the script (which doesn't work): https://drive.google.com/open?id=1BsY... Thanks in advance. See the error below: |

2019-08-21 00:22:39 -0500 | marked best answer | Setting daily and hourly setpoint temperatures in EMS Hi everyone, The purpose of this question is to set daily temperatures in Designbuilder. I've been trying many ways to do this, and I actually achieved it by means of overriding the heating and cooling setpoint schedules in EMS, but as a result the model became so heavy and running simulations was quite time-consuming. So, I'm going to specify what I've tried: By Compact Schedules in Detailed HVAC and Detailed HVAC data The main problem is that there is a limit in the lenght of compact schedules, so I can't specify setpoints for a number of hours within a day because the lenght is larger than Designbuilder allows. Please see below an example of this. By overriding the heating and cooling setpoint schedules in EMS It works, but the model becomes quite heavy and it's so tedious to work with it. Please see below an example of this: By overriding the heating and cooling actuators in zone temperature control in EMS I think this might be the best way to achieve this, but the problem is that, even setting the zone control thermostat to operative temperature, the setpoints are applied to zone mean air temperature. Please see below an example of the EMS script below, and please find attached the output files from the simulation in EP-Launch in the following link, both of them only for the day 01/01: Link: https://drive.google.com/open?id=1U_V...
