Abstract

Commercial buildings account for a significant portion of electrical energy demand in the United States. Thus, they serve as an ideal target for energy efficiency improvements, which can reduce congestion on the electrical grid and result in lower payments for building owners. One of the proposed approaches to improving energy efficiency in commercial buildings is transactive control, which allows system components to negotiate for resources within a market. The market is designed so that the control objective is met when components consume their allocation of energy. In this paper, a method is proposed to verify that the consumption of market participants matches their allocation. The method regards energy allocations at the beginning of market periods as predictions. Using collected measurements, actual consumption is then estimated at the end of the market period. Agreement between the predicted and estimated use indicates that the system component is behaving as expected. Initial results from the deployment of this verification method in a commercial building are reported, demonstrating the practicality and utility of the method.
