Turning off the lights or changing the lamps? : Evaluation of the electricity use at Uppsala University Hospital

Sammanfattning: This bachelor thesis will examine the actions that have been taken to lower the electricity use at Uppsala University Hospital during the winter of 2022/2023. To be able to evaluate the changes that have been done there will be a comparison between the winter of 2022/2023 and the winter of 2021/2022. During the recent winter Uppsala University Hospital made two different types of changes to make the electricity use decrease. Firstly, they continued with implementing technical changes which involves for example switching regular lights to LED-lights and ensuring that fans are operating efficiently. Secondly, they sent out information to every department through their website, newsletters, and other information sources. They also urged every department’s environment coordinator to spread awareness about the energy crisis and how to save electricity by creating behavioral changes as well. It was discovered that Uppsala University Hospital lowered their electricity use by 5,62% the winter 2022/2023 compared to the winter 2021/2022. However, the result that was concluded from this project was that it was quite difficult to distinguish how much behavioral changes contributed to the decrease. The only time it was possible to distinguish this was when bigger actions were taken, for example turning of the sauna. In most cases it was the technical changes that contributed the most to the decrease of electricity use.
