Problem presentation
When the new IKEA store in Malmö was installed in 2009 the advertising was aiming to
present the world's greenest IKEA store, where energy supply came from a geothermal energy
solution. Geothermal energy solutions are classified as renewable energy since 2007 by the
Swedish Energy Agency. A number of new IKEA stores have followed the same course and
are using different geothermal energy solutions as energy sources. IKEA Svågertorp in
Malmö is built and operated with ambitious environmental goals. The question of this report
will compare and put into perspective how sustainable the IKEA store really is, by visualizing
the geothermal energy solution and energy use at the store. Although geothermal energy is a
well-established source of energy it is relatively unknown in today's debates on renewable
energy. Also in IKEA, there is a certain lack of knowledge about how the geothermal energy
solution works. It may be that the solution is relatively autonomous and invisible, even more
the energy supplied from the geothermal energy solution meets the same requirements in
terms of heat and cold, like other energy plants can offer. The problem presentation is
summarized as follows:
- To visualize the geothermal energy solution and energy utilization at IKEA in Malmö
- To clarify how the electricity utilization could be lowered in the plant by continuous
monitoring and implementation of new routines for collecting data
Objectives
The report aims to present a visualization of the geothermal energy solution and the energy
use at IKEA's store in Malmö. The accumulation of energy utilization will be the basis for
IKEA to follow how the geothermal energy solution supplies energy and to allow the
monitoring and optimization of the plant to be improved, resulting in a good ability for
reduced use of electricity.
Method
The project is based on a review of related documents from the construction of the geothermal
energy solution at the IKEA department store built in Malmö in 2009. Discussions have been
held with people who have been, or are involved in the geothermal energy solution at IKEA
in Malmö. Logged and compiled data for temperature, flow and energy are visualized with
graphs that the operations staff at IKEA can update regularly, and use for optimization
measures and monitoring of the geothermal energy plant.

Results
The work with the visualization shows that some values should be logged and reported
differently than in the current situation, to allow for an accurate accounting of energy use in
the geothermal energy plant. Breakdown of reported electricity use for produced and
distributed energy shows that the geothermal energy plants performance enables more
accurate optimizations in respect to reduced electricity use. Simulations where the
temperature difference from the ground water circuit is increased to reduce the flow cannot
show any result indicating if the total electricity use would decline or not. Simulations are
based 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 to
enable monitoring and optimization of the plant. In comparison to other energy utilizing
commercial locals, IKEA Malmö has a low sum, indicating that the store keeps a path toward
a comparatively, sustainable energy use.
Conclusions
The energy use at IKEA Malmö can be better illustrated and more accurately subdivided with
accurate data logging. A great deal of the information contained in the current control system
that are logged and measured, is not performed in a manner that would best visualize energy
use and enable optimizations for a reduced electricity use in the plant. In order to follow the
plant in a more accurate way, different circuits should have individual metering for the use of
electricity. (Less)
