An M&V program generally includes sensors—which measure the 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. Building automation systems typically include the central processor needed for M&V, but not all of the sensors or the additional programming to tally energy use and track patterns. Adding these pieces to a building automation system, however, is relatively easy.
