Self-sufficient properties

Catena works continuously to reduce its properties’ climate footprint and operating costs by streamlining their energy consumption. A good example of this is Catena’s site on Köpetorpsgatan in Linköping, immediately adjacent to the airport.

Catena has three buildings at the site with 57,000 m² of warehousing and logistics space, with Arla, ICA and Bring, among others, as tenants. Catena also holds land suitable for another building of approximately 10,000 sqm.

For the three existing buildings, as well as for a future fourth building, a new, shared energy system is being built that will be entirely self-sufficient and will be disconnected from the district heating system. The new system is based on the heat generated by a cooling plant in a freezer unit in one of the buildings, being stored in a geothermal storage plant comprising some 50 boreholes with a total depth of 15,000 metres.

The properties’ respective systems are being connected and the heat generated by the freezers can be used for heating in all of the properties. The total heating consumption is estimated to decrease to 10 kWh/ m², compared with the average for Catena’s property portfolio at 38.5 kWh/sqm. Catena will continue to work with energy systems for several properties.
