1. A variable refrigerant flow system for a building, the variable refrigerant flow system comprising:
a plurality of indoor units for the building configured to generate activation requests;
a first outdoor unit configured to receive the activation requests and, in response to the activation requests, provide a refrigerant to the plurality of indoor units;
an outdoor meter configured to provide an outdoor unit electricity consumption measurement; and
a variable refrigerant flow management system configured to:
receive the outdoor unit electricity consumption measurement and activation data indicating the activation requests; and
