Herb Brooks National Hockey Center Ice Plant and Lighting Replacement

The ice system (refrigeration, waste heat recovery, ice rink floors, and dasher board systems) is original to the construction of the National Hockey Center in 1989. However, due to the age of the ice plant and refrigeration system, it is at a risk of failure and the R-22 refrigerant is obsolete, and since 2019 it is no longer produced due to its impact on the ozone layer. The existing mechanical, electrical, and building controls systems are also 30 years old, and in need of replacement to an updated, more efficient system. Lighting update to LEDs may reduce heat gain and the complementing work to the ice generation needs consideration for energy consumption reduction as a system. It is anticipated there will be a 35% reduction in energy use and carbon emissions from lighting replacements and 10-20% reduction from the HVAC upgrades.
