I have a OpenStudio model with a office tower and a multifamily tower. I am trying to create a custom meter so that I can have different utility rates for each part of the building (commercial for the office, residential for the multifamily).
I know that I can create a Meter:Custom object and apply a UtilityCost:Tariff to that meter. Looking in the eplusout.mdd file I have lighting electricity and internal load electricity for each zone, but all of the HVAC energy use is for the entire building. The residential and office towers have different HVAC systems, but I am not sure how to meter each system separately. Is this possible to do?
The only approach I can think of is to use output variables to get the total energy use from each HVAC system and then manually apply the utility rate. For the residential flat rate this would not be a issue, but this would be very difficult for the demand charges for the commercial rate.
Does anyone have a good solution for multiple meters in one model?
