With a series of smart energy solutions, Catena and tenant Oriola have together reduced energy costs and developed a logistics facility that is sustainable in the long-term. When the photovoltaic cell facility currently being installed comes into operation, it is estimated that the measures will have decreased energy consumption by 75 percent.
Situated right alongside the Mölnlyckemotet motorway junction in Härryda, Gothenburg, is the Härryda Solsten 1:102 property, which Catena leases to Oriola, a company that distributes pharmaceuticals and offers products and services for the wellness market. Oriola also owns the Kronans Apotek chain of pharmacies. The 25-metre tall high-bay warehouse is visible from a distance and the facility as a whole covers a total 25,406 square metres.
Pharmaceuticals for all of Sweden’s pharmacies, veterinarians and other wholesalers are warehoused on the premises, and clinical studies are also coordinated from here. Since 2018, Oriola has worked alongside Catena with the objective of reducing the property’s energy consumption. Gert Sahlén is the Facility Manager at Oriola and responsible for advancing these energy efficiency projects.
“One area of major environmental impact within Oriola’s operations is energy consumption, which involves everything from lighting in pharmacies and warehouses to the maintenance of our facilities, where it is important that we comply with the legal requirements for warehousing pharmaceuticals.”
The main source of heating for the facility in Härryda originally comprised district heating and the conversion to geothermal heating launched the extensive changes. According to Gert, the benefits of geothermal heating were obvious under the circumstances and the transition is in line with Oriola’s
“As a source of heating – geothermal heating is particularly well-suited to Oriola as our operations require large cooling aggregates. The installation allows us to take advantage of the heat generated by the cooling aggregates,” he says.
To extract energy during the winter and to store energy during the summer, 26 holes were bored into the ground. Catena’s investment has resulted in an annual reduction in energy consumption of 980,000 kWh, corresponding to annual savings in energy costs of SEK 750,000. To secure control of all of the equipment, the control system throughout the property was then replaced. Ventilation units, cooling units and heat pumps are now synchronised in the new system and everything is logged to ensure a complete
overview and full climate control, which is particularly important in the handling of pharmaceuticals.
A photovoltaic cell facility is currently being planned for the roof of the property with the aim of further reducing its already efficient consumption. Photovoltaic cells on the roof will permit annual savings of as much as 220,000 kWh. Catena’s property manager Jonas Larsson is leading the project.
“Nothing has been left to chance when implementing these energy efficiency measures. Together with Oriola, we are ensuring that the facility has optimum energy solutions fully meeting the needs of the operations and that are truly sustainable over time,” he asserts.
