An M&V program generally includes both sensors—which measure the energy volume and rate of flow, watts of energy draw, temperature, length of time, and other variables—and a central processor, which stores the collected information and helps building managers interpret it. A BMS typically includes the central processor needed for M&V, but not all of the sensors or additional programming to tally energy use and track patterns. However, adding these pieces to a BMS should pose little difficulty.
