HomeMy WebLinkAbout3.D. Ice Arena Radiant Heating 1.1) - CITY OF SHAKOPEE MEMORANDUM To: Parks and Recreation Advisory. Board Mayor and City Council From: Josh Barrick, Ice Arena Operations. & Programs Mark Themig, Parks, Recreation, and Facilities Director Date: November 17, 2004 Subject: Ice Arena Radiant.Heat Proposal INTRODUA TION The Parks and Recreation Advisory Board and City Council are asked to consider authorizing the installation of radiant heat in the Ice Arena. BACKGROUND In 1995 the Shakopeelce Arena was built to meet the needs of Shakopee Youth Hockey Assoc., Shakopee High School and the community. Since then the ice arena has seen an estimated 200,0000 patrons annually. The arena has been a focus of the hockey and skating community since the existence of the old Bubble site at Lions. Park. The Ice Arena continues to grow in interest and community pride. When the Ice Arena was built it was equipped with forced air heat. Although cost effective for construction, this system is inefficient for the arena because it attempts to heat the entire space. In addition, there were no thermostats to operate the unit - it was either full on or full off. In 2001, we added a thermostat to better regulate the usage and temperature and cut energy costs. DISCUSSION Our arena is cold, Due to the inefficiency of the heating unit, we usually do not have the heaton unless there are games or special events. This results in ongoing complaints from parents and visitors, and has been a recent discussion item at the Parks and Recreation Advisory Board. Most arenas use radiant heating systems instead of forced air units. These systems are more efficient because they heat the object below them instead of the space. Over the past few months, we have been working with vendors of radiant heat systems to determine the feasibility of installing a radiant heat system in our arena. One of the more significant issues is exhausting the unit. Most arenas that include radiant heat in the construction can exhaust the units through the roof. However, cutting holes in our roof was a significant concern for most providers. An alternative to exhausting through the roof is to exhaust the unit through a side wall. This seems to be the best approach. In addition to exhausting the unit, there are different types of radiant heating systems. However, gas fired tube heat seems to be the most cost effective, and is the choice in the ice arena industry. <;41> PROPOSAL There are many options to consider when choosing the layout and design. The design option that seems to be the best fit is a layout of four long tube burners along the top of the bleachers with venting going out the in the side wall. All four burners would be controlled separately to help ensure efficient operation. The heating design would also accommodate future expansion. We received three proposals for installation of a system. Although all the systems are generally similar, there are differences in the material used and the qualities of the burners were each unique. 1.) Infrared Heatino Sales and Service Inc. Cost was $30,793.00 to install the four burners over the bleachers and one burner by the score box area. It did not include electrical work. The option for the score box may be changed to not include a gas fired burner but replaced buy an electrical unit due to installation concerns. The quality of heat burners was good. 2.) Ron's Mechanical. Inc Cost was $28,174.00 to install four burners and all the venting and electrical work. Exhaust would be through the side of the building. The quality of the heat burners was excellent. Total turnkey work performed. 3.) Alan Mechanicallnc Cost was $22,800 to install four burners and gas piping and venting. The cost did not include electrical work or overtime. There was also an added cost for the option of venting through the roof of $3,400.00. The quality of the heat burners was good. Ron's Mechanical's system. is the best option, with high quality burners and all costs included. BUDGET IMPACT This would be an unbudgeted expenditure for 2004. However, we have identified funding for the work, and we feel it is warranted to address ongoing concerns from users. (Some of these users frequently comment that they are the only sports facility users that pay for some of the operational costs for the facility they use.) Funding for this work can come from the Recreation Fund, if Council desires to proceed with the work. There was approximately $92,000 in additional revenye thatwe generated in 2003 that Mr. Voxland has indicated could be used for this project. Since the units operate more efficiently than our forced air unit, the energy savings of this new heating method would be an estimated $3,000 to $5,000 annually. Center Point Energy is also researching whether or not there are rebates available for this work. REQUESTRED ACTION City Council is asked to consider adding radiant heat to the ice arena, and funding that expenditure from the Recreation Fund. If City Council agrees to this work, you are asked to award the work to Ron's Mechanical in the amount of $28,174.
