St. Cloud State University has embarked on a $12.9 million renovation of the Herb Brooks National Hockey Center, a facility that has been a cornerstone of Minnesota’s ice‑hockey culture for decades. The project aims to replace aging infrastructure while preserving the arena’s historic character.
Modernizing the cooling infrastructure
The center’s original cooling system relied on R‑22, a hydrochlorofluorocarbon that has been banned worldwide because of its ozone‑depleting properties. With the refrigerant no longer produced, the university seized the opportunity to install a next‑generation system that uses ammonia, a natural coolant that offers high efficiency and a dramatically lower environmental footprint.
Ammonia’s thermodynamic properties allow the new plant to achieve the same cooling capacity with less energy, positioning the arena as a model for sustainable sports venues. By eliminating synthetic refrigerants, the university not only complies with emerging environmental regulations but also reduces long‑term operating costs.
Lighting and controls get a boost
The renovation adds state‑of‑the‑art LED lighting throughout the rink and surrounding areas. Early simulations predict a 35 percent drop in electricity consumption, translating into measurable savings for the university and a reduction in carbon emissions.
Complementing the new lights, upgraded temperature controls give facility managers granular oversight of heating, ventilation and air‑conditioning systems. According to the university’s engineering team, the smarter controls could trim HVAC energy use by as much as 20 percent, further easing the building’s utility burden.
Beyond energy savings, the upgrades include reinforced safety features such as improved rink barriers and enhanced emergency lighting, ensuring that players and spectators alike benefit from a safer, more reliable environment. University officials say the improvements are designed to keep the Herb Brooks National Hockey Center operational for generations, serving both the campus community and the broader Minnesota hockey ecosystem.
The project reflects a broader commitment by St. Cloud State to blend tradition with innovation, reinforcing the arena’s role as a gathering place for alumni, youth leagues and regional tournaments. By investing in greener technology, the university hopes to set a benchmark for other collegiate facilities across the Midwest.
