Since spring 2010, when we began the major upgrade of our control and monitoring system, we have saved large amounts of energy, as you can see if you download the energy use report below. 2009 was the last year of operation of the old system and the old parameters that determined how the system should work. Since 2009 we have reduced our energy consumption by an average of over 3,085 MWh annually. In total, we have saved 25,578 MWh of electricity and 2,190 MWh of cooling between 2009 and 2018. Total 27,768 MWh. The graph below includes district heating, which has a negative effect on the figures.
