AdO Arena
AdO Arena is Norway's national swimming arena in Bergen, a 12,000 m² facility named after Olympic swimmer Aleksander Dale Oen and opened in 2014. Straume Rør installed a Tequs Aqua4 CO₂ heat pump that replaced an originally specified propane system, delivering roughly 1,100 MWh a year and cutting the building's district-heating consumption by 30 to 40%.
