REAL-TIME RESOLUTION OF CONFLICTING OBJECTIVES IN BUILDING ENERGY

We present an utopia-tracking multiobjective optimiza- tion strategy to resolve conflicting objectives in real-time energy management. Conflicts arise frequently from the need to balance economic and noneconomic metrics such as energy demand and occupant comfort. We demon- strate that the proposed approach leads to better perfor- mance compared with the traditional weighting approach. In particular, we demonstrate that improper adjustment of weights can lead to large excursions in performance. The proposed approach automatically locates the opti- mal weights and does not require the computation of the Pareto front, making it ideal for real-time implementation.
