Geoenergi på Ikea SvågertorpResultsThe work with the visualization shows that some values should be logged and reporteddifferently than in the current situation, to allow for an accurate accounting of energy use inthe geothermal energy plant. Breakdown of reported electricity use for produced anddistributed energy shows that the geothermal energy plants performance enables moreaccurate optimizations in respect to reduced electricity use. Simulations where thetemperature difference from the ground water circuit is increased to reduce the flow cannotshow any result indicating if the total electricity use would decline or not. Simulations arebased on instantaneous values so conclusions on the optimization results are difficult to reach.There is a clear need for measured values to be logged and documented with the target toenable monitoring and optimization of the plant. In comparison to other energy utilizingcommercial locals, IKEA Malmö has a low sum, indicating that the store keeps a path towarda comparatively, sustainable energy use.ConclusionsThe energy use at IKEA Malmö can be better illustrated and more accurately subdivided withaccurate data logging. A great deal of the information contained in the current control systemthat are logged and measured, is not performed in a manner that would best visualize energyuse and enable optimizations for a reduced electricity use in the plant. In order to follow theplant in a more accurate way, different circuits should have individual metering for the use ofelectricity.KeywordsEnergy utilization, operating efficiency, aquifer, geothermalenergy solutions, IKEA Svågertorp.8
