Arena Oskarshamn consists of an ice rink, gym and office space, swimming pool, leisure pool, café facilities and an outdoor artificial frozen bandy rink that in summertime is the football field with artificial turf.
The fact that everything is located in the same place means that the condenser heat from chillers for the ice rink and bandy rink can be used to heat the entire facility – the pool water in the three basins, air, and almost all tap water - in hockey and bandy season. Arena Oskarshamn consists of an ice rink, gym and office space, swimming pool, leisure pool, café facilities and an outdoor artificial frozen bandy rink that in summertime is the football field with artificial turf.

The fact that everything is located in the same place means that the condenser heat from chillers for the ice rink and bandy rink can be used to heat the entire facility – the pool water in the three basins, air, and almost all tap water - in hockey and bandy season. One of the chillers is also used as a heat pump when the bandy rink is not in active mode and heats the domestic hot water, bathing water and the water for heating the premises of the plant.

The heat in the shower water is utilized in a heat exchanger before the water goes into the sewer system and heats so incoming water in a first step. The heating system is also connected to the district heating in Oskarshamn in order to be able to buy the heat if necessary.

The Arena chosed to work with as few suppliers as possible. By having one brand for controlling all the technical features they have been relieved from demarcation issues between different systems and this gives the staff a good position to actively operate in an optimal way. Clear screen shots show how the system works. Air quality, temperature, water quality, recycling capacity, pressure and water levels are measured continuously. When the operator is sitting at the PC, he or she can control and change various parameters. When the operators is not there, they receives an SMS on their mobile phones if something happens that requires action. The system is web-based, which also gives the opportunity for operational monitoring and troubleshooting remotely.

"When we started planning for a new swimming pool, the idea to place it adjacent to the rink early arose. We saw the opportunity to utilize excess heat from the ice production instead of it just cooling off. That way we could save energy and reduce operating costs for the facility. Co-location also meant that we could create an efficient service organization of the entire Arena Oskarshamn. When everything is controlled by a superior system, the staff are in even better position to have a good handle on the different parts of the plant. Currently, we saved about 1 000 000 kWh per year. That means a reduced carbon dioxide emission by more than 600 tons per year! "
