Co-simulation between Esp-r and TRNSYS: More highly resolved modelling of integrated building and energy systems

The analysis of innovative designs that tightly inte-grate architectural and energy systems presents a chal-lenge for existing building performance simulation (BPS) tools. No single BPS tool offers sufficient ca-pabilities and the flexibility to resolve all the possi-ble design variants of interest. The development of a co-simulation between the ESP-r and TRNSYS sim-ulation tools has been accomplished to address this need by enabling an integrated simulation approach that rigorously treats both building physics and energy systems. The application and capabilities of this new modelling environment are demonstrated in this paper.
