Bid accepted for Jolley roofing project; board eyes AC options

Bid accepted for Jolley roofing project; board eyes AC options by M. Jill Karolevitz A bid of $93,390 was accepted Monday night by the Vermillion School Board for the Jolley School re-roofing project, scheduled for this summer.

In addition to the total bid, the project will include an alternate for the preparation of air conditioning installation at a cost of $975.

The school board also heard information regarding the installation of air conditioning at both Jolley and the high school. Bids have yet to be let for the project, but proposals from interested providers are being solicited by the school district via public notice publication, with a deadline of March 29.

As part of its 10-year contract as the heating and air conditioning provider for the school district, Johnson Controls implemented its consulting and planning service and produced a list of options for the school board to consider for the air conditioning project.

Brian Miller, sales office manager for Johnson Controls of Sioux Falls, discussed the options with the board Monday night:

Option #1

This would add air conditioning only, leaving existing heating/ventilation as is.

According to Johnson Controls, the system would have a life span of 10 to 15 years, with poor heating/cooling coordination and indoor air quality. Energy efficiency, rated on a scale from one to 10, is six. The system would have individual room cooling capability with a fair ease of maintenance rating. There would be no energy savings as far as heating is concerned, and operating costs would not be reduced.

Option #2

This would replace each room unit, retain steam heat and add terminal air conditioning to each unit.

According to Johnson Controls, the system would have a life span of 20 years, with good heating/cooling coordination and indoor air quality. Energy efficiency, rated on a scale from one to 10, is eight. The system would have individual room cooling capability with a good ease of maintenance rating. There would be some energy savings as far as heating is concerned, and operating costs would be reduced.

Option #3

This would replace each room unit, eliminate steam heat, convert to a water system, add a central chiller and replace boilers.

According to Johnson Controls, the system would have a life span of 30 years, with good heating/cooling coordination and indoor air quality. Energy efficiency, rated on a scale from one to 10, is nine. The system would have limited individual room cooling capability with a better ease of maintenance rating. There would be energy savings of 15 to 25 percent as far as heating is concerned, and operating costs would be reduced.

�In my professional opinion, just adding air conditioning is short-sighted,� Miller said to the school board. �It does not address the 30-year-old-plus heating unit that the school relies on most of the year for comfort. It also doubles the amount of equipment to maintain. From an engineering standpoint, it�s best to make the larger investment to replace aging equipment and incorporate air conditioning into that.�

Members of the school board will now study the options and gather more information before their next meeting on April 10.
