He noted the <br />existing unit has limited features for controlling the climate and that the humidity levels have <br />always been a concern. He reported the event center feels cold and clammy during the summer <br />months, which can lead to mold and mildew. He noted the current unit had a life expectancy of <br />15 years. <br />Public Works Director DeBar indicated he has met with several mechanical engineers to discuss <br />the situation and the current unit was working as it was designed, however, was not working as <br />the space needed. He explained that he recently spoke with a representative from Trane and was <br />recommending the current unit be replaced with a 50 -ton Trane unit with a Genesis Air Cleaning <br />system. The expense for the new system would be $159,640, with approximately $10,000 in <br />anticipated rebates from Xcel Energy. He noted funds have not been set aside for this expense <br />but funds were available in the Special Projects Fund. He reviewed the numerous benefits to the <br />new system and recommended the Council authorize the HVAC improvements for the Event <br />Center at the Community Center. <br />Council Member Mueller asked if the replacement unit would run more quietly than the existing <br />unit. Charlie Holt, Trane, indicated the new unit would run more quietly and more efficiently <br />while greatly improving the air quality in the room. <br />Council Member Mueller commented that the damp summer in 2012 led to mold and mildew <br />remediation in the Event Center. This in turn affected the room rentals at the Community Center. <br />She was in favor of fixing the problems to ensure that additional work was not needed. <br />Council Member Meehlhause questioned if any other areas of the Community Center had air <br />quality issues. Public Works Director DeBar stated the Event Center was a large portion of the <br />space in the building, with the largest rooftop unit. He anticipated that by positively impacting <br />this space, the air quality of the entire building would improve. <br />Council Member Meehlhause inquired how confident staff was that the new unit would resolve <br />the issues at the Event Center. Mr. Holt was confident this was the right solution for the space. <br />Public Works Director DeBar indicated he was relying on the opinions of the electrical engineers <br />at Trane and from a third party. He explained he was working on a replacement plan for all City <br />building HVAC units so that in the future these expenses would be written into future budgets. <br />Council Member Hull inquired why no other bids were received for the HVAC unit. Mr. Holt <br />explained Trane competitively completed a bid through TCPN seven years ago and was awarded <br />the contract as the best value. <br />Council Member Gunn asked for Parks Supervisor Steve Dazenski's opinion on the proposed <br />HVAC unit. Mr. Dazenski fully supported the proposed HVAC unit stating it would greatly <br />improve the air quality at the Event Center while also regulating the humidity. <br />Council Member Mueller questioned the lifespan and warranty on the HVAC unit. Mr. Holt <br />anticipated the new unit would last 15 years, but has been known to run for 20 to 25 years. He <br />
