88 boreholes will heat Umami Park

88 boreholes have been drilled down to a depth of 300 meters in the rock layers in Umami Park, Sundbyberg. Geothermal energy is being extracted here for the central substation that will supply the Central block’s 37,000 square meters with heating and comfort cooling. The plant is operated using Wallenstam’s wind power and has now been commissioned in connection with the first tenants moving into the modern, reconstructed premises.

“Drilling for geothermal energy and building a central substation in such a central location at the same time as construction and development are in full swing in Umami Park has been a challenge. Meanwhile, it also shows that active environmental work can be pursued everywhere,” says Mathias Aronsson, Vice CEO of Wallenstam.

The central substation has been built in the property’s ground floor and will supply the entire property with heating and cooling. In summer and fall, cool air will be extracted from the rock in order to cool the property while at the same time surplus heat from the property will be pumped down into the rock.  This in turn means that the rock will become warmer and this heat will be stored for the coming winter. 

“We want to do more than just build new housing; we also want to contribute to active urban development. When we develop and build new properties, we are doing it for the future. We were the first in the sector to be self-sufficient in renewable energy through our investment in wind power. Our investment in the Central block in Umami Park will make the energy use there totally carbon-free, and will have a positive impact on future operating expenses,” says Mathias Aronsson.

The reconstruction of the Central block in Umami Park means that we are welcoming new tenants, including Convendum during 2020. The partners in the geothermal heating project are Creanova and Bygg R1.
