Heat and hot water to the arena and the adjoining properties. The total contract included a thermal storage with 91 holes at 180 m. Charging the storage takes place in summer when the playing field acts as a large solar panel which heat is absorbed through a loop system located under the pitch.

Additionally, excess energy from making ice for the bandy rink, energy traditionally lost, are now utilized. The football pitch is kept free from frost in the winter and is therefore also playable in winter.
