EN HILLS <br /> MEMORANDUM <br /> Item 1.A <br /> DATE: August 25, 2009 <br /> TO: Honorable Mayor and City Council <br /> Ron Moorse; City Administrator <br /> FROM: Michelle Olson, Parks and Recreation Manager <br /> SUBJECT: Green Lighting System for hockey rinks and softball fields <br /> BACKGROUND <br /> During the most recent ice rink season, Councilmember Holden inquired about the possibility of <br /> the City utilizing more energy efficient lighting at the ice rinks. Since that time, staff met with a <br /> few different lighting companies to discuss options for upgrades. The easiest and most cost <br /> effective upgrade appears to be with Musco Sports Lighting. Staff met with a representative <br /> from Musco to review the City's current lighting systems and to analyze the benefits of <br /> upgrading. <br /> Craig Gallop from Musco Sports Lighting visited all of our rinks and also analyzed our current <br /> lighting at our Perry Park softball field. After reviewing the lighting, he recommends the City <br /> consider upgrading to the Musco Sportscluster Green lighting system for four of our ice rinks, <br /> Cummings, Freeway, Hazelnut and Perry. He does not recommend upgrading the lighting for <br /> the softball field at Perry Park, as the current lighting is a Musco system with reasonable energy <br /> efficiency. <br /> The Sportscluster Green System (SCG) is the most advanced and energy efficient hockey rink <br /> lighting available. This system will significantly increase the light on the rinks to 25 foot- <br /> candles. He estimates that the current systems at the four rinks are approximately 10 foot- <br /> candles. In the lighting industry, footcandles are a common unit of measurement used to <br /> calculate adequate lighting levels of workspaces in buildings or outdoor spaces. Footcandles are <br /> a unit of measure of the intensity of light falling on a surface, equal to one lumen per square foot. <br /> The SCG system will reduce unwanted spill and glare light, making the lighting friendly to <br /> residential areas. <br /> BUDGET <br /> \\Metro-inet\ardenhills\Admin\Council\Agendas &Packet Information\2009\09-21-09 <br /> Worksession\Packet Information\Park lighting upgrades - green 0909.doc <br />
