You can’t calculate ROI of a metering system any more precisely than you can for a financial accounting system, but experience shows energy monitoring always leads to reducing consumption by 10 to 20 percent or more.
People seem to think that because it can turn energy-consuming equipment off and on, a control system is an energy management system, but it’s not. If you want to manage energy, you must measure energy.
Many companies are ready to sell you their technology, but the typical energy management or control system may not provide the information, analysis and reports you’ll need to diagnose problems and improve efficiencies.
Maybe one of the reasons your competition sometimes beats your price is that they’re doing a better job of holding down energy costs, for example, by participating in an electric power demand response program.
