gas and electric meters at the same building

Hello,

What do you recommend when a building has gas and electric meters?  I read on https://github.com/openeemeter/eemeter/blob/fc91df2b5fa69125a85b1235d24783c350d5b99a/docs/caltrack_compliance.rst:
 
For natural gas meter use data, the function :any:`eemeter.fit_caltrack_usage_per_day_model` must set fit_cdd=False and cooling_balance_points=None so that models using cooling degree days are not considered.
 
3.4.3.1:any:`eemeter.fit_caltrack_usage_per_day_model` must set fit_cdd=True, fit_intercept_only=True, fit_cdd_only=True, fit_hdd_only=True, fit_cdd_hdd=True for electricity data, and fit_cdd=False, fit_intercept_only=True, fit_cdd_only=False, fit_hdd_only=True, fit_cdd_hdd=False for gas data.

So do you recommend building separate models for gas and electric with the parameters changed?

Definitely, for buildings with multiple meters, there should be a separate model for each meter. It is important to use different parameters for gas and electricity, as you read in the CalTRACK compliance document.

OK, thank you very much for clearing that up.
