Towards the development of a coupled model for district simulation: buildings, energy systems and microclimate co-simulation

Abstract : This paper introduces a methodology of a coupling procedure based on a detailed district energy model from urban microclimate and a second one with a detailed description of the entire energy system of the district. The microclimatic model is able to represent the thermo-radiative and mass flow balances. The transient energy system simulation platform is capable to consider the entire energy system of the district (including thermal and/or electrical grids and their respective energy storage/production on a central or local level). In parallel, both tools allow to compute the thermal processes of the buildings concurrently. Thus, considering the building as the boundary between both tools, we examine it as the key coupling parameter. The spatial and temporal complexities and their impact on the simulation results are analyzed in a first step in order to validate the coupling methodology. In parallel, modified meteorological data that account for the urban form were obtained in offline coupling. Finally, we demonstrate some of the possible outcomes through a real study of a newly refurbished district in La Rochelle, France.
