Aldrich Arena will get an estimated $3.6 million worth of renovations next year, as Ramsey County gets ready to phase out the use of Freon at its ice rinks and switch to a more available coolant.
The county also will repave the Maplewood arena's parking lot; upgrade its heating, ventilation and lighting systems; and bring the arena into full compliance with the Americans with Disabilities Act. The upgrades are expected to save the county an estimated $30,000 a year in energy costs, county spokesman John Siqveland said.
The work is expected to start in the spring and finish by Nov. 1, said Mark McCabe, county Parks and Recreation director. "We'll work around the existing schedule as much as possible to make sure there's no ice time closures."
Ramsey County has been wrestling with the future of its 13 sheets of ice, at 11 sites, for several years.
A task force found in 2016 that demand for ice time had been slipping at the county's arenas since the start of the Great Recession in 2007. The county's annual average of about 14,000 rental hours had fallen to about 10,000 hours by the 2011-12 season. But since 2016, demand has been steadily climbing.
The county already has rented out 16,500 hours of ice time for the upcoming 2018-19 season, McCabe said.
The most pressing question now is what to do with each arena's cooling system.
With manufacture of the gas R-22, or Freon, set to end in 2020, the task force recommended that Ramsey County slowly begin the expensive process of replacing its cooling systems with ones that use more environmentally friendly ammonia-based coolants.
