On-line parameter estimation of reduced-order models for buildings energy dynamics using the modulating function method

This paper considers parameter estimation of a reduced-order model (ROM) for building energy dynamics using the modulating function (MF) method. After briefly presenting a model of building dynamics, we recall the MF method and present a way of determining a modulating function directly from the available data instead of defining it a priori. Then, we look at the application of this method in a case study, where actual weather-based data (solar radiation and outdoor ambient temperature) is used. The results together with the advantages of the MF underline the potential of the proposed algorithm.
