According to a new guide from the International Ice Hockey Federation, improving the energy efficiency of an ice rink is the most important way to make a facility more sustainable.
New data from consultancy firm EKA Finland shows the Pirkkala ice rink operates on less than 1.4MWh of electricity per day, making it one of the most efficient ice rinks in the world.
Humidity control is essential to reducing energy usage, says report by EKA.
EKA Baltic will offer expertise in natural refrigerants, particularly CO2, to ice rinks and other applications in the Baltic region.
New requirements for ice rinks and arenas in Olympic and World Curling Federation (WCF) competitions, issued by the WCF, mention only natural refrigerant CO2.
