Energy follow-up on a modern hospital : An analysis of the energy model at Nya Karolinska Solna (English)
Abstract [en]

The purpose of this study was to develop an operation method to manage the energy model at Nya Karolinska Solna and apply it to a fully operational floor in the facility. Deficiencies and improvement potential was then analysed for future management of the model.

Manual measurements were performed on the examined floor regarding heating, cooling and facility electricity and were then compared to the corresponding parameters calculated by the model. The model was calibrated with actual airflows, time schedules and internal gains to get a representative comparison with the measured energy use.

The results show that the developed mode of operation works well for the examined floor but has some improvement areas for when it should be applied to the the entire facility as a lot of processes connected to updating the model are time consuming. Improvement potential was found concerning the acquisition of data and calibration of the model. The proposed mode of operation could be improved by firstly concluding the actual usage of the occupants to adjust air flows, time schedules and internal gains and secondly, by implementing a system of reporting future deviations from normal operational patterns.

The total actual energy use compares well to the energy use calculated by the model. However, if comparing the parameters individually, deviation is evident. It was also found that values in the model for internal gains are overestimated during days and underestimated during nights and weekends resulting in a deviation of the compared parameters of the examined floor.
