I understand that it is possible to output carbon emissions, energy consumption (including electricity, gas, water, etc.) from the WRF BEM result, like set up the parameters of bldg_physics, but I cannot set the output parameters in namelist.input and correctly run real.exe. Is it because using BEM should compile WRF differently from the default or something else?
how to output energy consumption and carbon emissions from BEM

Thx for answering. I learned that BEM can output the air temperature / relative humidity indoor and outdoor, and also can output the energy consumption and carbon emission. However, I can't find the correct way to output these variables. Are these variables available in the wrfout? Or should I calculate them by myself according to the wrfout?
bldg_physics is the variable chatGPT gave me, it said it represents the energy consumption setting, haha. But I can't find it in WRF official website.

I hope this information is helpful for you.
To output the variables you're interested in, you will need to modify the Registry.EM_COMMON file in your WRF directory. Here are the steps:
- Locate the variables: Open the Registry.EM_COMMON file and search for the relevant variable names (e.g., SF_AC_URB3D, LF_AC_URB3D, or CM_AC_URB3D).
- Activate the variables for history output: In the lines corresponding to these variables, change the package designator from r to rh. This will ensure they are included in the wrfout history files.
- Recompile WRF: After saving your changes, run the ./clean -a command and then recompile the model.
This process is based on the solution provided in the support forum, which you can review here for more context: How to produce HFX and LH at different heights?.
