Long-Term Benefits

“Persistence of savings. . . . installations that boast real-time measurement of savings tend to have higher savings initially and experience savings levels that remain high‌â€? (G. Kats et al, US DOE) Schneider Electric

Benchmarking Requires Data

● Data comes from meters and production variables. ● Meters for all utilities: ● WAGES (water, air, gas, electricity, steam). ● Production variables include: temperature, humidity, occupancy, patient beds, ft2, number of widgets produced, litres of water pumped, etc…

Feedback - Power to the People

● Successes or failures should be pushed to external facing tools to allow users within the facility to manage energy “ontheir-own”. ● Displays in lobby kiosks, web-sites and financial reports. ● Similar to speedometer in car while driving
