Simulation model validation Clause Samples

Simulation model validation. Both the Östersundom and Kalasatama simulations were validated against their corresponding pilot cases. The purpose of validation was to fix errors in the simulation model and at the same time calibrate the model to better match real cases. The Östersundom simulation model was validated against measured data from School of Sakarinmäki. The simulation model is robust compared to its pilot since it represents a bigger area with numerous buildings and a larger overall energy system. However for validation, the Östersundom simulation model was scaled down by fitting its parameters to match the system at the School of Sakarinmäki. Practically this meant dimensioning the district heating pipes and changing storage tank’s size and properties. The measured energy demand and solar heat production was connected to the simulation model as inputs. The model parameters in model validation are listed in Table 4.
