Community Activity Center

The original ice arena at the Community Activity Center in Brooklyn Park, Minnesota was constructed in 1983 and served by a direct Holmsten Ice Rinks System. As with most of these systems that were installed in the 1980’s, equipment failures have increased maintenance costs and raised concern about reliability.

B32 Engineering Group was the lead consultant on this project and worked closely with the City of Brooklyn Park and their Energy Service organization to design a unique solution for the replacement of the Holmsten system and other mechanical systems. The solution includes using city well-water as a geothermal heat exchange system. This design allows the new refrigeration setup to operate at higher than normal efficiencies, unmatched by other designs in the industry. The new plan will also capture 100% of the waste heat generated from the refrigeration system for reuse in the facility.

This new, energy-efficient design substantially reduces the greenhouse gas emissions of the facility and lowers its carbon footprint without sacrificing performance of the two ice sheets. The first of the two ice sheets were placed on-line in August, 2010 and is exceeding performance and efficiency expectations.
