IS IT POSSIBLE TO USE A SINGLE REDUCED MODEL FOR A NUMBER OF BUILDINGS IN URBAN ENERGY SIMULATION?

초록

Roles of urban energy simulation become important for sustainable city design and energy management. In this context, a single reduced model that can describe a number of buildings is proposed and tested in this paper. Simulation results show that the proposed single reduced model for multiple buildings can give very similar results with separate reduced models in load calculation. However, the calculation time of the single reduced model is more important than the case of several reduced models because the PID controller used in Dymola to calculate building loads requires more iterations for a MIMO (multi inputs and multi outputs) system than a SISO (single input and single output). In conclusion, the use of a single reduced model can be a solution for urban energy simulation, but further work is needed to simplify calculation processes by an optimal solver.
