New AHUs resulted in an 89 percent energy saving

Strömkarlen 4 | Helsingborg

In the heart of Helsingborg, the 7,000 square metres large property Strömkarlen 4 is located. It accommodates business and care facilities, offices and a parking place of 63 lots. The owner is Stadsrum Fastigheter.

Consat were assigned to generate a complete solution for a more energy-efficient building and in June 2021, two new air handling units from our Envistar Flex range were installed. Earlier, the property was ventilated with 8–10 other units and it was now, in other words, time for an upgrade.

Lars-Olof Lindeheden, COO at Consat and responsible for this project, explains that the reality has surpassed their expectations when it comes to the energy saving.

- Our projects around Sweden usually result in low energy usage for the properties, but we could hardly wish for a better result from the new solution at Strömkarlen. In August, September, October and November, the energy saving was as high as 81–89 % with a peak of 89 % during the month of September.

Lars-Olof adds that the air handling units operated optimally with the prevailing temperatures during these months. For the most part, it was only the fans that needed energy. Also, during the rest of the months since the installation of the new units, the energy saving has been distinctive with an average of 66 %.
