Active Efficiency in Action
The best way to understand the value of Active Efficiency is to see it in action. There are many examples that demonstrate the potential of Active Efficiency. Between the economic, social, and environmental benefits, the hard work that goes into making these examples successful is something to be celebrated.
Kent State University Central Plant Optimization: Ratcheting Up Energy & Cost Savings
Kent State University in Northeast Ohio is a living example of how an Active Efficiency approach to energy management can boost savings by integrating digital technologies with traditional energy efficiency measures. A longtime passenger on the energy efficiency train, Kent State had already lowered its energy use intensity to 24% less than peer universities by 2016, but wanted to push the envelope further. To reap deeper savings, Kent State invested in model predictive controls in 2016 that integrated its building systems to respond dynamically to energy needs. The investment led to estimated savings of $470,000 in annual utility costs by November 2018.
The Johnson Controls Central Plant Optimization™ (CPO) technology used at Kent State to support its central utility plant’s energy management system features two key elements of Active Efficiency: time-dependent response and systems integration. The CPO technology predicts campus loads and energy prices to make decisions on equipment operation that reduce both energy demand and costs. The success of the system depended on partnerships with time‐of‐use experts, a funding mechanism that reduced risk (energy savings performance contract), and executive‐level prioritization of energy management.
