Mastering Sustainability Operations in Ice Hockey Practice Rinks

Facility operations for ice hockey practice rinks encompass several integrated systems designed to maintain a safe, efficient, and comfortable environment for training and recreational use. Key areas include the building envelope, air conditioning and dehumidification, ice-freezing refrigeration systems, Zambonis, and stadium lighting.
The building envelope serves as the primary barrier for thermal and moisture control. It emphasizes tightness more than thermal insulation to minimize infiltration, which introduces humidity and increases energy demand.
Sidewalls are insulated to at least R-19, with roofs at R-30 or higher. Ceiling materials like polished aluminum, reduce radiant heat transfer to the ice, potentially lowering refrigeration loads by 30% or more. Frames use lattice, ring, or beam structures for cost-effectiveness in practice rinks without large seating areas.
Vapor barriers and sealed joints prevent condensation, frost heave, and structural damage. Large glazing is minimized to avoid energy loss. A heated sub-slab, often using waste heat from refrigeration, protects the ground from freezing directly below the ice pad.
The main challenge of operations is to balance cold ice temperatures of 20–24°F with arena air temperatures of 55–60°F, and to keep relative humidity around 40–50%. Desiccant dehumidifiers maintain a low-dew-point in ice environments, and are supplemented by mechanical ventilation, heat recovery, and CO₂ monitoring. Ice rinks generate significant moisture loads from skaters, spectators, resurfacing, and infiltration. Maintaining low humidity prevents fog, condensation on the ice and ceiling, and prevents structural issues.
Refrigeration for ice surfaces ranges from 45–300 or more tons depending on size and use. Modern systems incorporate heat recovery, variable controls, and monitoring for energy savings. Annual brine testing maintains pH and performance.
Traditional propane Zambonis are reliable for heavy use and their internal combustion engines. They require propane storage, ventilation for emissions, and maintenance for fuel, oil, and air quality monitoring. They impact indoor air quality with indoor emissions.
Battery-powered models are quieter, produce no indoor emissions, and have up to 80% fuel savings and 35% maintenance reduction. They are preferred for small facilities due to lower long-term costs although upfront costs are higher.
LED fixtures dominate for energy efficiency with 50–70% savings versus metal halide lights, and they have long lifespans, durability, and dimmability. They also reduce heat load on the ice and pair well with energy management systems.
Ice rinks present a challenging set of operational expectations that require an engineering team to have an in depth understanding of systems integrations, and additional skills to excel in sustainability.
