The three-rink Ice Centre facility at the Promenade is one of the most remarkable skating facilities in Colorado. The existing lighting retrofit conserves up to $30,000 of energy costs per year. Inefficient metal halide lamps have been mounted on the three rinks of the Ice Centre that consumed over 1,000 W of electricity.
New Lighting at the Ice Centre
This led to a new approach where the facility can be retrofitted with fixtures from lighting manufacturer, Precision-Paragon [P2], demonstrating 35%-45% reduction in energy consumption for each fixture.
The Ice Centre facility was digitally modeled by the team at Colorado Lighting. Precision-Paragon (P2). The company helped Colorado Lighting with photometric files for retrofitting the fixtures and this enabled the digital prototype of the Ice Centre to precisely demonstrate the light levels, which would be generated by the retrofit.
An energy-efficient lighting system resulting from the integration of 10 lamp and 12 lamp T5HO fixtures was designed by Colorado Lighting. Each fixture in the facility retrofit was constructed with custom optics, spacing and reflector design at [P2], which enabled the selection of suitable fixtures for the retrofit. As a result, the entire 102 fixtures were rapidly deployed in three weeks.
The system was designed based on bi-level switching. Each 12 lamp fixture will operate at 33%, 66% or 100% of its available light output and each 10 lamp fixture performs with 30$, 60% or 100% of its available light output, thereby enabling the Ice Centre to optimize the light output according to the activity on the rink.
Recreational skating requires 30% of the fixtures' output, whereas league hockey requires 60% of output. With these fixtures, Ice Centre can save over $10,000 of energy costs per year.
The new system offers significant benefits such as uniform light level adjustment throughout the entire surface of the ice, consistent operation with less noise, instant warm up generating radiant, bright light, and provides longer maintenance intervals.
