Each BMS includes metering devices that collect information about energy, water, and gas usage. Those recordings are needed for more than just an invoice. As Peter Drucker said, “If you don’t measure it, you can’t manage it.” For metering, we should add one more statement before that sentence: “If you can’t collect it, you can’t measure it.”
We need all of the information from the building to measure the usage and then think about optimizations.
