Abstract

Systems and methods of providing intelligent energy-efficiency performance coaching. Energy efficiency performance is measured by a performance score calculated in association with various efficiency metrics. The performance score may be provided as feedback to the operator and may further be used by an operator reward system and/or gamification system. An intelligent energy-efficiency coach responds to variability in operator behaviors by using tunable variables to bias weighting constants assigned to the efficiency metrics to normalize calculations of performance scores. The intelligent energy-efficiency coach may use reinforcement machine learning techniques to calculate tunable variables and adjust performance scores on an ad hoc basis. A mutual learning process may be performed, where the operator may learn energy saving behaviors from feedback provided by the intelligent energy-efficiency coach to improve energy efficiency and the intelligent energy-efficiency coach adjusts tunable variables to help the operator improve their energy efficiency performance.
