Runestone Community Center

The Runestone Community Center is home to many community events, including Alexandria Blizzard NA3HL Hockey, Alexandria Area Hockey Association, Vikingland Curling Club, Alexandria Figure Skating Club, Alexandria High School Boys and Girls Hockey, and many more.

With so many organizations relying on these rinks, B32 applied a step-by-step approach to the Runestone Community Center project, starting with a detailed discussion of options for renovating or placing the existing ice system for their two rinks, RCC (main rink) and WR (west rink). This included whether to continue using R-22 refrigerant or switch to ammonia or a different blended refrigerant.

Estimated costs and energy savings were reviewed and discussed. In the end, it was determined that the best option was to replace the existing direct refrigeration system with an indirect R-22/calcium chloride refrigeration system.

Considering future needs, the City also approved up-sizing the refrigeration system to allow for the connection of the existing second ice sheet when the current refrigeration system needs replacement, or for serving a future third ice sheet.

A unique, and money saving, feature of the new design is a recycling snow melt pit that recycles water for the condenser system, saving more than 385,000 gallons of water use per year.

In 2014, the City wanted to replace the R-22 system with an ammonia based system, so they turned to B32 to design a new energy efficient refrigeration system and to replace the west rink floor.
