Hi there,
@chris @mostapha

I’ve been trying to output CO2 carbon emissions from electricity in Cairo, Egypt.
I know this has not been available in Honeybee-Legacy, so I used the additional strings as follows:

  Output:EnvironmentalImpactFactors,

That worked properly, and I got a .Meter file in the results file containing all the gases emissions and their carbon equivalent.
Now when I tried to do the same with HB 1.7, it did not work. I figured out about the Title 24 weather files and the supporting TDV files to add as schedules for fuel prices, yet still that did not help. Here’s the additional strings in HB 1.7 (I copied the TDV file into OS/Energyplus directory, so it is reading the file correctly):

Hello @YASSER_IBRAHIM! what errors are you getting when you try with 1.7?

@TrevorFedyna

Thank you for your interest. I’ve just figured out what the issue was. OS 3.6.1 uses Energy+ 23.1, which does not take units of measure, nor Emissions per unit factor. I checked the IDF files and found that when I first used the strings as they are, the inputs have shifted 2 rows below - apparently placing strings instead of integers etc.,

Untitled-1
Untitled-11920×1012 130 KB

I removed the two lines, so every input has got into the right place

Untitled-21920×1002 211 KB

Now everything is working properly.
And the Strings should be as follows:

Thank you for your help!
