Consider the impact of an M&V program on mechanical system design requirements.  Keep in mind whether or not your mechanical system is capable of providing the necessary outputs for the BMS or metering system. The energy usage outputs are typically listed as kW, BTU, or therms over a given period of time. An automated record on a BMS or a metered reading on the equipment may be manually carried out at regular intervals. The specifics of the output metric and duration need to be determined in your M&V program and depend on the systems installed.
