Tiivistelmä
The long-term study of buildings with advance energy solutions has resulted in the need of continuous calibration and validation of energy models. Often the first essential step in this work is to create a base model that runs with reasonable computed time and results. The main purpose of this Bachelor’s thesis was to make a base energy model of Sheet Metal Center, the pioneer commercial-research hall aimed at near-zero-energy building (nZEB) compliance in Finland. The thesis was commissioned by Sheet Metal Center (within HAMK's project ''Multi-skilled designer in energy technology in building'').
The building case materials were mostly taken from HAMK's facility management library documents and commissioning report of AXSuunnittelu. The simulation work was performed with IDA ICE (v4.1). This program provided the possibility for detailed inputs, customized technical plant and investigation of all relevant variables and parameters.
The simulation process was the focus and the obtained results were either discussed and/or compared with some empirical measurement data. Two models were presented. The first model indicates a good design when sizing the heating equipment. The second one showed a positive sign for compliance with the latest Finnish draft regulations about nZEB. Nevertheless, there were still some questionable discrepancies between the model results and actual building energy consumption.
Overall, the model’s geometry, structure and technical plant were built thoroughly. Some views on the possible causes of mismatches were presented and a plan was proposed for future research. It is clear that an accurate calibrated model will be valuable for various applications, such as optimized building controls, fault detection and energy piles study.
