The goal of this paper is to present a dynamic model of an integrated energy system based on Near-InfraRed faÃ§ade panels and their validation. The innovative solution has been developed in the framework of the â€˜ENVISIONâ€™ European Project funded by the EU H2020 Programme. The whole system integrates the ENVISION faÃ§ade panels with a mGT, a prototype heat pump, and two thermal storages composing an innovative microgrid. This paper briefly describes the whole system and the model of each component together with the main characteristic equations. The work is mainly focused on the model development and validation of the solar-faced panelsâ€™ systems and the heat pump and its single components. The model will be used to evaluate the impact of the temperature variation of the warm water produced by the panels over the heat pump performance and responsivity and to define the proper integration strategy. The validation of the solar faÃ§ade panels model and the HP model has been carried out using experimental data and the results showed that the realized models have reliability of more than 98%.
